Hair Growth & Length Retention

Topic guide

Hair Growth & Length Retention

If your hair looks like it hasn't moved in two years, your scalp is almost certainly still growing it; what's happening at your ends is the problem. This section covers both halves: how growth actually works on textured hair, and how to keep the length you're already making.

Read this first

It's not a growth problem. It's a retention problem.

Textured hair grows about a third of an inch a month, which comes out to a little under four inches a year. That's an average, and the spread between people is wide; the same measurements put individual rates anywhere from roughly two to five inches a year. Your own rate is set mostly by your genetics, your age, and your health, and no oil, vitamin, or regimen moves it much.

So if your hair has looked shoulder-length for three years, your scalp is still making close to four inches of new hair every year. You're losing it at the other end, to breakage, split ends, damage from styling, and over-trimming. Length retention just means keeping the length you already grew.

Curly and coily hair loses more of that length than straight hair does, because every bend in your strand is a weak point, and the oil your scalp makes can't slide down a coiled strand the way it slides down a straight one. That's how your hair is built, not something you're doing wrong.

Almost everything on this page is more useful once you know which one you're actually fighting: slow growth, or lost length.

You're in the right place if

Your hair seems stuck at the same length no matter what you do

You're shedding more than you think you should be, and you can't tell what's normal

Your edges are thinning, breaking, or not coming back after a protective style

You want to know whether a growth oil, supplement, or treatment is worth buying

You're growing out a cut, a color, or a relaxer and want to do it without damage
