Chances are you've heard of the term "dread detox," especially if you are loc'd. It's a tried-and-tested way to deep-clean your dreads.
There's a lot of conflicting information out there about how to deep clean your dreads via detoxing, so we'd like to clear things up. In this article, you'll learn all you need to know about dread detoxing.
Dread Detox Steps
- To detox your hair, fill a basin halfway with warm water and stir in a tablespoon or two of Arm and Hammer Pure Baking Soda. Add a tablespoon of ReaLemon 100% Lemon Juice and 5-7 drops of Gya Labs Lavender Essential Oil so your hair smells good afterward. Keep your Bragg Organic Apple Cider Vinegar aside for a separate rinse afterward, because the two cancel each other out in the same basin.
- Submerge your dreadlocks entirely in the solution, ensuring a thorough soak.
- Gently massage your scalp to dislodge built-up residue.
- Allow your dreads to soak for about ten minutes. Watch the color change in the water to assess how much buildup is removed.
- After soaking, rinse your hair thoroughly. Rinsing will ensure all the detox solution is washed out.
- Now pour the vinegar rinse through your dreads: about a quarter cup of Bragg Organic Apple Cider Vinegar in a quart of warm water. Rinse that out of your hair too.
- Follow up with a clarifying shampoo to cleanse away the dislodged buildup.
- Then, use a deep conditioner to restore your hair's natural oils and moisture. This moisture was stripped away during the detox.
Using these dread detox steps, you can clean your dreadlocks and keep them healthy and strong.
Key Takeaways
- Detox Recipes for Clean Locs: Use baking soda, apple cider vinegar (low pH), citric acid from lemon juice, and optional lavender oil for deep cleansing to remove product buildup and keep dreadlocks cleaner and lighter. Use the baking soda and the vinegar one after the other, never mixed together.
- Combat Scalp Problems: Address issues like dry scalp flakes and promote healthier hair growth by thoroughly rinsing your hair and using an essential oil treatment afterward.
- Best Results in Detox: Soak dreads in the baking soda solution for about ten minutes, and repeat the process another day if the water turns dark brown, indicating significant buildup.
- Post-Detox Care: After the detox soak, wash your hair with a clarifying shampoo and deep condition to replenish natural oils.
- Avoid Over Detoxing: While it's a good idea to detox your locs regularly, avoid overdoing it to prevent stripping away your hair's natural moisture, which can lead to scalp problems and slow hair growth.

What Does It Mean to Detox Your Dreads?
Before we dive into the dread detox process, we'll explain the term "detox" and why it's important to detox your dreads. Detox essentially means getting rid of toxic or unhealthy things.

Your hair is already growing. The problem is keeping it.
On average, hair grows a third to half an inch a month, and curlier hair tends to grow more slowly. If your length looks stuck, that’s your hair breaking off as fast as it grows in. Here are the seven causes of breakage and the weekly routine that stops them.

What Is a Dread Detox?
A dread detox is a deep clean for your dreadlocks. You soak them in something that loosens the residue a normal wash leaves behind, rinse it out, and follow up with a deep conditioner. The residue (or build-up) here refers to product that remains on your hair strands and your scalp’s natural oil, dirt, and the smell that comes with them.
Two things decide whether a dread detox will work for you. The first is what is actually built up in your dreads, because a soak only helps in certain situations. The second is how you use the baking soda and the vinegar: one after the other, never mixed in the same basin, for a reason worth understanding before you start.
Start with what you’re dealing with.
Not all build-up is the same thing
What’s actually in your locs
A detox soak is often recommended for all five scenarios, but it only helps with two. First, determine which scenario you’re dealing with, because it will dictate which detox approach you need.
| Verdict | What you notice | What it usually is | What actually removes it |
|---|---|---|---|
| Washes out | Dreads feel slippery or coated, and product seems to sit on the surface instead of rinsing away | Gel, wax, butter and cream that never fully rinsed out. The most common kind by far. | A clarifying shampoo, worked into each dread and rinsed in sections. Regular shampoo already lifts this out, and baking soda adds nothing it can’t do at a safer pH. |
| Washes out | Roots feel greasy within a day or two, and your dreads feel heavier than usual | Your scalp’s natural oil, which locs hold onto instead of letting it travel down the strand. | Wash more often rather than harder. This isn’t a detox problem, and a monthly soak won’t fix a weekly washing gap. |
| Needs the right product | Dreads feel rough or stiff, shampoo won’t lather well, and you’re on hard water | Calcium and magnesium from your tap water, left behind on the hair. | A chelating shampoo, which means looking for EDTA or disodium EDTA on the label. The evidence that minerals damage hair is mixed, so treat this as worth trying rather than a certainty. |
| Won’t wash out | A gray or fuzzy cast running through the loc rather than sitting on it | Lint from towels, bedding, hats and clothing, woven into the loc as it tightened. | Nothing you can soak. It’s inside the loc now, so the answer is prevention: satin at night, and no cotton towels on wet locs. |
| Not build-up | A sour or musty smell, usually strongest a day or two after washing | Moisture trapped in the core of the loc that never dried out. | Drying time, not a soak. Squeeze the water out, then dry properly. Soaking your locs for half an hour makes this one worse, not better. |
Two of the five scenarios can be resolved with a normal clarifying wash. One needs a different product. Two can’t be washed out at all, and a long soak actively works against the last one.
Do You Need to Detox Locs?
Hair products like shampoos, gels, and wax leave residue in your dreads. The residue accumulates over time and can give your dreads a slippery, coated feel even after using a clarifying shampoo.
It could even get as bad as leaving a dirty brownish or ashy color on the surface of your dreads or weighing your dreads down.
Another surprising fact is that a portion of the build-up results from a naturally occurring substance on your scalp called sebum. It is perfectly normal and advantageous for your scalp to produce sebum. Sebum production serves as a natural oil for your scalp and hair.
But over time, the sebum can start to build up in your hair. The nature of dreads makes it easier for the build-up to accumulate and remain even though you regularly wash your hair.
Although clarifying shampoos can prevent residue build-up, they cannot do much for you when you already have considerable product build-up. This is when a dread detox is in order.
How to Deep Clean Dreads: Step-by-Step
If you've decided that you need a dread detox, this section is for you. The most popular detox method is the detox rinse, with its main ingredients being baking soda and apple cider vinegar.
The good news is you can do it by yourself if you follow the steps outlined in the following sections.
What's in a Dreadlock Rinse (i.e., Apple Cider Vinegar Rinse)?
Baking soda (also known as bicarbonate of sodium or sodium bicarbonate) is a substance that will draw out the residue in your dreads and make it easy to rinse or wash out.
While it helps rid you of the product build-up and other things that may be coating your dreads, it also strips your hair of its natural oil and throws your scalp pH level off balance.
That is because, on the pH scale, which determines the level of acidity and alkalinity of a substance, baking soda is a 9 (very basic). However, the hair's pH ranges between 4.5 and 5.0, just like the sebum produced by the scalp.
This is where apple cider vinegar (ACV) comes into the equation. ACV contains acetic acid, amongst other nutrients that are good for your hair. It's rich in vitamins B and C, inhibits the growth of fungi and bacteria, and may even help with dandruff.
That’s the part worth checking before you put it anywhere near your hair, and it does not hold up.
Here’s why the two never go in the basin together. The measures you usually see are a quarter cup of baking soda, which weighs about 53 grams, against three quarters of a cup of regular vinegar, which contains about 9 grams of acid. That much acid can cancel out roughly 12 grams of baking soda, so the vinegar is spent almost immediately and about three-quarters of the baking soda is never canceled out at all.
Put it the other way around: the vinegar in your basin can cancel out about one tablespoon of baking soda, not a quarter cup. To cancel out a quarter cup, you would need somewhere around three and a quarter cups of vinegar.
That fizzing is not the mixture working. It’s the vinegar being destroyed. What you are left with is a solution still sitting high on the pH scale, far from the mildly acidic range your hair likes. That is why the vinegar goes in on its own afterward, as a rinse.
Every study we could find
Does the baking soda and ACV detox actually clean your dreads?
The standard recipe cancels itself out in the basin. Here's every claim behind it, and what the research actually says about your dreads.
| Study | Who or what was tested | How it was given | What it found |
|---|---|---|---|
| The recipe itself | ¼ cup baking soda plus ¾ cup apple cider vinegar in one basin | Mixed together, then soaked | Points againstBaking soda is in roughly four-to-one excess, so the vinegar's used up on contact and about three quarters of the baking soda is still sitting there.That fizzing is the vinegar being destroyed. You're left soaking your dreads in a basin still sitting high on the pH scale, with none of the acid left to bring it back down. |
| Gavazzoni Dias et al. | 123 shampoos measured | Topical | StrongA high pH increases the negative charge on the hair surface, which makes strands drag against each other and can wear away the cuticle, the outer layer of the strand, and cause breakage.Baking soda solution sits at pH 9, level with the highest-pH shampoo they measured. That drag matters more in dreads than loose hair, because you can't comb a loc out to undo it. |
| Ogunleye et al. | Literature review of the ACV rinse | Topical rinse | WeakThey found a notable deficit in the literature, and call the ACV rinse an anecdotal remedy lacking data.ACV is often credited with vitamins B and C, and with fighting fungi, bacteria and dandruff. None of that's supported for a rinse on your hair. |
| Luqman et al. | Hair from 70 people, treated with hard or deionized water | Soak | WeakHard water lowered the measured strength of the hair.Small, one region, and hair from men only. It supports the idea that minerals matter, but it doesn't support it strongly. |
| Srinivasan et al. | 20 volunteers, hard water against soft water for three weeks | Washing | Points againstNo statistically significant difference in surface damage between hard and soft water.Worth knowing before you buy anything sold to fix mineral build-up in your dreads. The evidence cuts both ways, and this one didn't find the damage. |
Sources, in order: The recipe itself 2026, Gavazzoni 2014, Ogunleye 2025, Luqman 2018, Srinivasan 2017. We searched PubMed for the baking soda and apple cider vinegar loc detox and hair; last checked 2026-09-07.
Why pH matters more in dreadlocks
Gavazzoni Dias and colleagues measured the pH of 123 shampoos and found that a high pH builds up negative electrical charge on the surface of the hair, which makes strands drag against each other and lifts the cuticle, the overlapping outer layer that keeps a strand smooth.
On loose hair that drag is annoying but you can comb it out. Inside your dreads the hairs are already pressed together for good, so there’s nothing to comb. Damage in your dreads adds up and it stays, which is why the same pH matters more here than it would on loose hair.
Ingredients You Need for the ACV Rinse with Baking Soda
Below are the ingredients you'll need to make your dread rinse:
- A sink or basin half-filled with comfortably hot or warm water
- ¼ cup of baking soda - Arm and Hammer Pure Baking Soda
- ¾ cup of apple cider vinegar, for the separate rinse - preferably Bragg Organic Apple Cider Vinegar
- A tablespoon of lemon juice - ReaLemon %100 Lemon Juice
- About 5-7 drops of lavender oil (optional) - Gya Labs Lavender Essential Oil
Note: It's common to substitute lavender oil with rosemary essential oil or an essential oil blend (e.g., tea tree oil, coconut oil, jojoba oil, etc.).
Make the Detox Mixture
- Fill a basin or sink with warm to hot water.
- Take ¾ cup of apple cider vinegar and add it to the water.
- Don’t pour the baking soda into the vinegar. Mixed together they cancel each other out, so they only work one after the other.
- You can now add a teaspoon of lemon juice.
- Add 5-7 drops of lavender essential oil to improve the smell of the mixture.
- Stir the mixture with your fingers or a large spoon.
Soak Your Dreadlocks in the Detox Solution
Used in the right order, the two steps are: a brief soak in warm water with a tablespoon or two of baking soda, no more; a thorough rinse until the water runs clear; then a separate rinse of diluted vinegar, roughly a quarter cup in a quart of water, poured through your dreads and rinsed out.
One after the other, never mixed. Ten minutes is plenty for the first step, and the rinsing between them is the part that actually dislodges the build-up in your dreads.
- Make sure that you position yourself as comfortably as possible, as the soak will last for about ten minutes. Some like to do their dread detox in the sink, and this works for many.
- Place your head in the sink or wash basin. Make sure that all of your dreads are completely submerged in the mixture. Using a cup, scoop up some of the mixture, pour it on your scalp, and gently massage your scalp to help dislodge residue there. Do this for a few minutes until you feel your hair and scalp is clean enough.
- Settle into a comfortable position and let your dreadlocks sit for about ten minutes. Set a timer to keep track of time.
- When time is up, use your hands to work the mixture into your dreads gently. Then squeeze from root to tip to get the rinse out of your hair. Depending on how much build-up you had, the color of the mixture may become murky and can range from light brown to deep brown. If the water is very dark brown, this indicates that you may need to repeat the process to remove more buildup.
- Once you feel like you've removed enough buildup, rinse your hair thoroughly in the shower or sink and move on to the next step.
Clarify and Deep Condition
In the final stage of the detoxing process, you'll complete your regular hair routine. Wash your dreadlocks with a clarifying shampoo to wash away the buildup dislodged from the rinse.
Next, go in with a deep conditioner to restore some of the moisture and oils stripped from your hair during the detox process. Some people also incorporate a hot oil treatment into their deadlock regimen.
Dos and Don'ts of Dreadlock Detoxing
Dread detoxing is a fairly straightforward process, but some people still run into issues like dry hair, an irritated scalp, and more.
To reduce your chance of experiencing a hair disaster, we recommend reading and following the below dos and don'ts of dreadlocks detoxing.
Dos
- Make sure to thoroughly deep condition your dreads after a detox.
- Match the method to the build-up. A clarifying shampoo handles product; a chelating shampoo, which just means one that grabs onto minerals, handles hard water, and neither needs baking soda.
- Detox your hair 2-4 times a year or whenever you think your dreads need it.
Don'ts
- Don’t soak for half an hour. The cleansing ingredient in a shampoo does its work in minutes, and the rest is just your dreads getting heavier and taking longer to dry.
- Do not detox more than four times a year. Exposing your hair to baking soda too often is not good for your dreads.
Pros and Cons of Dreadlock Detoxing
If you're not quite sure whether you'd like to detox your dreads, the below pros and cons will help tremendously.
Pros
- Detoxing your dreads is excellent for getting rid of product residue build-up.
- Your locs lather and take water properly again once that coating comes off.
- A diluted vinegar rinse brings your hair’s pH back down after a high-pH wash, which is a real effect and a small one.
- It improves the overall appearance of your dreadlocks.
Cons
- Due to the harsh ingredients, it can be quite stripping to the hair.
- Mixed together, the baking soda and vinegar cancel each other out, so what you’re soaking in is a basin still sitting high on the pH scale.
- Washing at that end of the scale makes strands drag against each other, and you can’t comb a loc out to undo it.
- A thirty minute soak leaves your dreads heavy and slow to dry, which is what causes a musty smell in the first place.
- It does nothing for lint, which is often what you’re actually looking at.
How much does a loc detox cost?
At home, close to nothing. A clarifying shampoo costs what your shampoo costs and a chelating one is not much more, and both do more for your dreads than baking soda and vinegar.
In a salon it is usually bundled into a wash and retwist rather than sold on its own, so most of what you pay for is the retwist. If it shows up as a separate line on your bill, it’s worth asking what is in it, because the answer is often the same baking soda and vinegar.
When a detox is the wrong idea
Two of the five rows in the table above cannot be washed out at all. We would rather tell you that now than have you spend a wash day on it.
If what you are seeing is lint, no soak will touch it. Lint from towels, bedding and hats gets woven into your dreads as they tighten, and by then it is part of the loc. Your answer is satin at night and no cotton towels on wet dreads.
If what you are smelling is sour or musty, that’s trapped moisture rather than build-up, and a thirty minute soak makes it worse. That one needs drying time and a look at what is going on in the loc, not a detox.
Dread Detox FAQs
What Do You Need for a Dread Detox?
Less than you might think. A clarifying shampoo handles product build-up, and a chelating shampoo, which just means one that grabs onto minerals, handles hard water; look for EDTA on the label. If you want to do the traditional soak, you'll need baking soda and apple cider vinegar, but you'll use them one after the other rather than mixed, and you'll need a deep conditioner afterward either way.
What Is the Best Detox for Locs?
The one that matches what's actually in your dreads. Product and oil come out with a clarifying shampoo. Minerals need a chelating shampoo, which is one that grabs onto minerals; look for EDTA on the label. Lint doesn't come out at all, and a musty smell is trapped moisture rather than build-up, so a soak makes that one worse. Work out which you've got before you pick anything.
How Long Do You Have to Leave Dreads in the Detox?
Around ten minutes. Twenty or thirty minutes is far longer than any shampoo needs, and the rest of it is just your dreads sitting in warm water getting heavier and taking longer to dry. Ten minutes is plenty, and drying your dreads properly afterward matters more than the soak did.
Is It Good to Detox Dreads?
Clarifying your dreads properly is worth doing, because dreads hold onto product and oil in a way loose hair doesn't. The traditional baking soda and vinegar soak is a different question. Baking soda sits at about pH 9 against your hair's 4.5 to 5.5, and washing at that end of the scale makes strands drag against each other, which you can't comb out of a loc.
How Long Does It Take to Detox Your Locs?
About half an hour end to end, most of which is rinsing and squeezing rather than soaking. Then give your locs a full day to dry, and longer if they're thick. The drying is the part people skip, and it's the part that causes the sour smell they end up detoxing for next time.
Can You Detox Your Locs With Apple Cider Vinegar?
You can rinse with it, diluted, after you've washed and rinsed. What it won't do is what the recipes claim. A 2025 review in Cutis looked for evidence behind the ACV rinse and found a notable deficit in the literature, describing it as an anecdotal remedy. It's an acid rinse, which is a reasonable way to bring pH down; it is not a treatment.
Can I Use Regular Vinegar for Dread Detox?
White vinegar is the same acid at a similar strength, so it does the same job. Apple cider vinegar gets recommended for its supposed extra benefits, and those are the claims the research doesn't support. Pick whichever you have, dilute it, and use it as a rinse rather than a soak ingredient.
