How Long Do You Leave Bleach On Your Hair

How Long Do I Leave Bleach In My Hair-1

Bleach is commonly believed to be more effective if left on for an extended period of time due to a widespread misconception. Wrong!

Bleaching your hair for more than 30 minutes is not recommended. This is to keep your hair from becoming permanently damaged.

If you leave bleach on your hair for a few hours, some people believe it will last longer, but this is not the case at all. Your hair will become dry and orange if you do this.

Bleaching should be limited to no more than 30 minutes to avoid damaging the hair we've worked so hard (and paid so much) to achieve!

How Does Bleach Dye Hair?

Bleach is so named because of its reputation as a "aggressive" product.

Dissolving the dye and opening the hair cuticle are the two mechanisms at work here (melanin). Leaving keratin on longer and longer causes the protein bonds to break down.

Ammonia- and hydrogen peroxide-based bleaches are the most commonly used bleaches in the world today. It's difficult to avoid damage when there aren't any alternatives.

According to Nikki Goddard, a certified hairstylist and make-up artist, "peroxyde-free" products should be avoided.

Hair could have been further damaged by the use of a new oxidizing agent.

What Happens If You Leave Bleach On Too Long?

If you don't take proper precautions, the fun of bleaching your hair can be overshadowed by the dangers. Even if you do everything right, you still run the risk of damaging your hair or getting your desired hair color wrong.

One way to prevent this is to not leave your hair in the bleach for an extended period of time, which can cause it to dry out and break more easily (which makes the colour uneven).

What Kind Of Bleach Should I Use?

How Long Do I Leave Bleach In My Hair

Bleaching agents can be divided into four categories:

Peroxide – The strongest option is hydrogen peroxide with a concentration of 10% or more. Your hair will gradually lighten if you use hydrogen peroxide on a regular basis. Make your hair blonder by using it on dark hair.

Hydrogen Peroxide Solution - Hydrogen peroxide is more potent, but this is still a viable alternative. It's still a great product that won't damage your hair and does the job. When working with extremely dark hair, professional hairstylists prefer to use peroxides rather than home users.

Bleach Powder Mix- Bleach powder can be applied to hair easily and uniformly by mixing it with 10% hydrogen peroxide or ammonium bromate. When it comes to bleaching your hair at home, powder bleach mixed with water is one of the most inexpensive methods.

Liquid / Creme Developer- Before applying the developer cream to your hair, it must be mixed with either peroxide or this solution. You can use creme developer on its own if you already have light blonde hair and want to lighten it even more. The hydrogen peroxide content is insufficient for dark hair, so check your natural hair color before attempting this method if you have dark hair.

Some are stronger and take longer to develop your desired shade than others because of the variations in concentration.

The Difference Between Hair Volume Developer Strengths 

First, we'll cover the basics to help you understand the differences between hair developer levels. This chemical, when combined with hair color or bleach, allows the hair cuticle to open up.

On the developer packaging, the number indicates that it contains hydrogen peroxide (10, 20, 30, or 40). A look at some of the developer's strengths is in order below.

  • If you want to darken your hair just a tad, a 10 volume developer is ideal. Developer in 10 volume only adds a tint or shade to the same lightness level as your base color due to its low peroxide content (3%). You can easily go from one lighter to another darker shade or maintain the same hair color.

  • The 20 volume developer is used primarily for permanent dye or temporary color. It opens the hair cuticle and lightens the hair by one to two shades, thanks to its peroxide content (6%), which is ideal for completely covering gray or white hair with a beautiful, long-lasting color.

  • The higher peroxide level in the 30 volume developer makes it lighter than the 20 volume developer by two or three shades (9 percent ). If you want to lighten your hair just two or three shades, this is a good option for you. It's best to use the '30 volume developer' if you want light brown to honey blonde curls if your hair is dark.

  • The most potent developer, 40 volume, can have a significant impact on the color of your hair. 40 volume developer has a peroxide concentration of 12 percent and can lighten hair by up to four shades.

How Long Do I Leave Bleach In Brown Or Black Hair?

It's extremely difficult to lighten dark hair colors like black and brown.

Your hair may need to be lightened more than once, or the bleaching strength may need to be increased.

For as long as you like, you can use as much bleach as you want. As a result, the time limit is 30 minutes. However, you should be aware that bleaching may be required.

If you don't know what you're getting yourself into, do a strand test before each application.

How Long Should You Leave Bleach On Your Roots?

Do you ever wonder how long you should leave bleach on your hair for?

To determine how long you need to leave the bleach on your hair, consider the color of your hair and whether or not it has been dyed before.

If you have naturally light hair or hair that has never been dyed, you may be able to get away with just 5-10 minutes of bleaching rather than the full 30 minutes.

For those of us with darker hair, this is not the case. Observe the fact that our hair's roots are darker in color than the rest of it. Right now, the grown-out root look and blonde hair with dark roots are extremely popular.

Because it won't look authentic, avoid going platinum or white blonde at the roots.

Best Tips for Bleaching Hair at Home

Minimize Damage

Bleaching, a potent chemical, has the potential to damage both your hair and skin. When applying the bleach, take care not to get any on your face. Put on gloves and old clothes that you don't mind getting stained to keep your hands safe.

Prepare Your Hair

This is a grueling process because bleaching removes so many nutrients from hair.

It is possible to minimize the damage to your hair by using hydrating products such as deep conditioning treatments, moisturizing shampoos, hair masks and hot oil treatments. One alternative might be to use the squish-to-condish method.

For a few days before bleaching your hair, you should use gentle shampoos like sulfate-free ones.

Hair oils, such as coconut oil, may be applied to the hair before it is bleached. Reduces hair damage by hydrating and protecting the hair's proteins.

Blonde is a potent product, but it can only lessen the damage to your hair.

Apply Bleach Correctly

You should always follow the manufacturer's instructions, no matter how often you've bleached your hair before.

Apply the bleach completely to ensure a smooth finish. Using sections of your hair, spray hairspray on each strand to ensure that it is evenly coated.

Finally, keep your hands away from your scalp if you're applying bleach to it. Bleach can damage your scalp's skin, so start with a small amount and work your way down.


If you have any questions or concerns about the procedure described here, seek the advice of a colorist (or a hairdresser).

Bleach should not be left in your hair for an extended period of time in order to preserve your hair's strands. The manufacturer's instructions should always be read and followed before using any product.

For at-home bleaching, we recommend using a lower-level developer and never speeding up.

People with curly hair are more prone to hair breakage as a result. Once your hair is naturally curly, it's best to gradually lift your curls.
