How Long Do You Leave Bleach in Your Hair? (The Definitive Answer)

Bleach is a powerful chemical that should be handled with care. But how long do you leave bleach in your hair?

The answer to this question depends on the type of bleach that you are using and what color you want your hair to be.

In this blog post, we will go over some tips for applying bleach safely and maintaining healthy hair!

What Type of Bleach Should I Use?

There are three types of bleach: powdered, liquid, and cream. Cream is the most gentle of these options but also takes more time to see results that you will like.

Powdered bleach can be stronger than both creams or liquids (but still weaker than traditional bleaching) so it's a good choice if you want fast results without the harshness of liquid bleach.

Liquid bleach is a good choice if you want results that are both fast and strong, but it can also be the harshest option because your hair will absorb more chemicals with each application (so many people recommend using this sparingly).

How Long Should I Leave Bleach in My Hair?

There are a few things to consider when deciding how long you should leave bleach in your hair: the type of bleach that you use, the color of your hair, and the results you desire.

  • Powdered bleach will require the least amount of time to work. If you are using powdered bleach, you should leave it in your hair no more than 15-30 minutes. 
  • Liquid and cream bleaches will require a little more time. Leaving these types of bleach in your hair for 20-45 minutes should be sufficient to achieve the results you want.
  • If you are looking to lighten your hair, the amount of time that it takes for bleach to work will depend on how dark or light your hair is to begin with.  If you have dark hair, leaving bleach in your hair for an hour or more may be necessary. If you have light blonde to brownish-blonde hair, you should only have to leave bleach in your hair for 20-30 minutes.
  • If you are trying to remove a color like blue or green from your hair, leaving bleach in for around an hour should do the trick.
  • Finally, if you are trying to achieve a very light blonde color from dark brown hair, it will require bleach that has been left in for up to three hours.

Remember that every strand of hair absorbs bleach differently, so it is important to experiment with time and temperature in order to achieve the results that you desire.

Your best bet is to apply the bleach and then wait half an hour before washing it out. This will give you time to make sure that your hair isn't burning or itching, but it also won't let the chemical sit so long that your scalp begins to burn.

After this initial thirty minutes, you should wash out all of the bleach from your hair then let it dry naturally or use a brow dryer if you want to speed up the process.

There shouldn't be a need to reapply the bleach if you followed these steps and didn't wash out your hair before half an hour was up!

Can I leave bleach in my hair overnight?

No! This is a terrible idea and can cause damage to your hair.

While some people believe that leaving bleach in overnight will speed up the bleaching process, it actually weakens hair strands. It's better to leave on for half an hour as described above rather than risking further damage by going over this time frame.

Leave bleach in your hair for too long and you could end up with a fried head of straw.

It's better to use bleach sparingly so that it is effective but won't cause lasting damage!

Steps to Take Special Care of Your Hair After Bleaching

If you've bleached your hair and are trying to care for it in a healthy way, there are some steps that you will need to take.

Since bleach can be drying on the scalp, consider using a moisturizing shampoo and conditioner after each use of bleach or any other chemical treatments so your locks stay hydrated! You should also use a deep conditioning treatment once or twice per month to keep your hair moisturized and healthy.

Another thing that you can do is minimize heat styling after bleaching. Irons, straighteners, curlers, and blow dryers will all damage locks over time if used too much! If possible, try to hold off on using heat styling tools for at least a month so you can let your hair repair itself.

If bleaching has left your scalp dry and itchy, then consider using an anti-dandruff shampoo to clear up the problem. This will help get rid of any flakes or build-up that is causing irritation on your head!

All in all, the trick to healthy bleached hair is using gentle products that won't affect your bleach or cause damage.

If you stick with this advice and don't overdo it on the bleach treatments, then your hair should be back to normal in no time!
