What Is Wella 7A?

How to Use Wella 7A on Your Hair

If you’ve decided that Wella 7A is what you need to get the cool medium-blonde hair you’ve been dreaming of, keep on reading. We’ll give you some clear instructions to follow to get the best possible results.

  1. Survey the health of your hair. If your hair is already damaged, dry, and brittle after lightening, applying demi-permanent dye to it isn’t the best idea. Compromised hair needs TLC first.
  2. With gloved hands, mix the Wella 7A hair color with the Wella Color Charm Activating Lotion in a 1:2 ratio. You can use a 10-volume developer of your choice in place of the activating lotion if necessary. Add both to a plastic mixing bowl and mix with a whisk or a plastic spoon.
  3. Apply the hair dye mixture to your hair, starting at your roots and slowly moving to your ends. Be generous with the dye, and take your time to ensure that every strand of hair is coated. If you’re not thorough, you won’t end up with even results.
  4. Leave the dye to process for 20 minutes. Then, rinse your hair with lukewarm water until all the dye is gone.
  5. Finish up by conditioning your hair with a color-safe conditioner or deep conditioner.

Should You Pre-lighten Your Hair Before Using Wella 7A?

One of the most common questions people have about using Wella 7A is whether they have to pre-lighten their hair. The concern is warranted, considering the fact that bleaching or otherwise lightening your hair can drastically damage it.

If you’re concerned about the health of your hair, you should definitely avoid chemicals wherever possible.

Thankfully, pre-lightening your hair is not a requirement when using Wella 7A, as we mentioned earlier. But, in some cases, you will need to pre-lighten your hair if you want to achieve the color on the box.

A young Brazilian female used Wella 7A with sodium sulfite to create the perfect blonde shade on her natural curls.

Dark brown hair won’t magically lift to a medium blonde with just Wella 7A. Ideally, your hair will be one shade lighter than the color of the toner before application.

Note: We don’t recommend pre-lightening your hair if it’s at all fragile. Though demi-permanent dye is not the worst chemical you can expose your hair to, it can still damage your hair.

How to Pre-Lighten Your Hair with Bleach

Bleach is a very efficient way to lighten your hair. But it’s also one of the harshest hair treatments out there.

To ensure the integrity of your hair and avoid wasted time, here are the steps you need to take:

  • Ensure that your hair doesn’t have visible buildup on it. If it does, you’ll need to clarify it first with a clarifying shampoo 48 hours before pre-lightening.
  • Prepare your space for the bleaching process. Put on an old T-shirt, put down newspaper everywhere to catch spills, and ensure that the room is properly ventilated.
  • Put on gloves and mix one part bleach powder and two parts 20-volume developer in a plastic bowl. The two products should be smooth and completely integrated for the best results.
  • Separate your hair into at least 4 to 6 sections. The more sections you make, within reason, the easier it’ll be to get the bleach onto your hair quickly and evenly.
  • Use a tinting brush to apply the bleach to your hair, starting with the mid-lengths and ends. Once those are completely coated in bleach, go back and apply the bleach to your roots.
  • Set a timer for 45 minutes. You probably won’t need to leave the bleach on for that long, though. Check your hair every 5 minutes to see how quickly it’s changing. Once your hair is about level 8 or 9, go to the next step.
  • Rinse the bleach from your hair with lukewarm water, massaging your scalp in the process.
  • Follow up with a shampoo session to remove any bleach that may still be hanging out in your hair or on your scalp. This step isn’t negotiable. You can’t always see bleach residue.
  • Proceed with your Wella 7A hair color treatment.

Note: It could take several bleaching sessions to get your hair a shade lighter than medium blonde. It’s not unusual for people to have to do 2 or 3 bleach sessions in total. The number of bleaching sessions you’ll need depends on how dark your natural hair is, your hair history, the strength of the developer, and more.
