Does Bleaching Your Hair Make It Grow Slower?

Bleaching your hair is a quick and easy way to lighten your hair. But all those harsh chemicals that strip color can leave hair damaged.

Many people claim that their hair grows slower than usual after bleaching, leading to confusion about whether bleaching actually slows down hair growth or if these claims are merely myths.

It turns out these claims have some truth to them, but bleach doesn’t directly make your hair grow slower.

This might sound contradictory to you but we’ll clear up any confusion in this article, explaining how all of this adds up.

Does Bleaching Slow Down Hair Growth?

No, it’s a misconception. Bleach does not cause hair to grow slower than usual. While your hair may appear to be growing slowly, it’s not!

Instead, the bleach may have caused your hair to become brittle after bleaching. As a result, hair will break off as it grows out.

It is also important to remember that, on average hair grows only 1.27 cm per month. Though this growth rate varies among individuals, it will take about 2 months to grow hair an inch after bleaching even for people with normal hair growth.

So, if you are more aware of your hair growth after bleaching, it might look like it’s growing slowly but actually, it is growing as it used to grow before.

Why Does Hair Seem to Grow Slowly After Bleaching?

There are several reasons behind bleached hair appears to grow slower. As we mentioned earlier, sometimes people think their hair is taking longer to grow after bleaching but actually, they were not aware of their hair growth rate before.

In this case, the only reason your hair seems to grow slower after bleach is overthinking. You need to compare how long it used to take to reach a certain length before and after bleach.

But if you actually notice your hair has not gotten longer or growing slowly it is because the bleach probably caused your hair ends to become damaged.

The growth in damaged hair is less noticeable than in healthy hair. So it creates an illusion of slower hair growth.

You can also consider this example to understand the cause. The average hair growth rate is the same for curly and straight hair. But wavy hair looks shorter than straight hair for the same length.

It is also possible that you are losing your hair or your hair is breaking due to the damage. When hair loses moisture, it’s prone to fallout, frizziness, and breakage. Due to unhealthy conditions, your hair is unable to reach a longer length. 

If this is the case, it is crucial to spend extra time caring for your hair after bleaching it than you normally would.

Caring for your damaged bleached hair will make your hair look longer at the same pace as it does under normal conditions.

You can also consider adding Vitamin B and biotin into your diet to help promote hair health. Split ends can also lead to breakage so trim your hair ends.

Can Combing Your Bleached Hair Cause It to Break?

Yes! Another thing that can cause issues with hair growth when you have bleached hair is combing your hair regularly. It is crucial to comb your hair to keep it from getting tangled.

Unfortunately, combing often causes hair to get pulled out of your head under normal conditions. When your hair is brittle from bleach, it is more likely to break. 

To avoid breakage, give your hair time to recover. Give it time to relax and recover by avoiding further coloring, heavy styling, and rebleaching for at least three months after bleaching. 

If you need to re-bleach, only apply bleach to the grown-out roots rather than your entire head of hair.


So, bleached hair does not take longer to grow than natural hair. If you notice slower hair growth after bleaching, it is because the hair is brittle and breaking because of splits.

The best thing you can do to avoid this problem is to follow all aftercare instructions. If you’re ever concerned about the health of your hair, consult with a hairstylist for help and guidance.
