Can You Bleach Your Hair Twice In One Day Without Damages?

Bleaching is involved when you have dark hair but want to dye it with a light color. Depending on how dark your hair is and what color you want to dye, you may need to bleach more than once. This leads to a commonly asked question: Can You Bleach Your Hair Twice In One Day?

To help you answer this question, we will discuss the nature of bleaching and its influences on your hair. Plus, you will find helpful advice in this post to keep your hair healthy.

How Does Bleaching Work?

Hair bleaching is a process very different from hair dying as it’s aimed to lighten your hair color. 

This process is also known as oxidation, using an oxidizing agent to remove your hair pigment. The most widely used oxidizing agents are ammonia and hydrogen peroxide, which are often mixed to achieve more stability. 

After bleaching, your hair color will be a few shades lighter than the previous one.

Can You Bleach Your Hair Twice In One Day?

The short answer is No, you cannot.

Sometimes, you have to bleach your hair more than once to get the color shade you want. And this is okay.

However, once you successfully lighten your hair color in the first bleaching attempt, you may be tempted to do it again right away to increase the effect. This is a bad idea.

For example, you can’t and must not bleach your hair twice in a row, even within 24 hours. Hair bleaching is an aggressive process that causes damage to your hair shafts, especially when you repeat it in a short period of time.

Adverse Effects Of Bleaching Twice In A Day

Burn your scalp

The scalp, which is the skin on your head, is very sensitive. Such a powerful chemical like a bleaching agent will likely cause damage to your scalp and make it feel itchy.  

Alter your hair

If bleaching is not done right, it can turn your hair into something frizzy, dry, and coarse. This is clearly shown through the look of the hair and to the touch as well. 

Not just that, your hair will become gummy, break easily, or shed in clumps. 

Wrong color

When bleaching, if the ingredients are not mixed properly, you may end up with discolored hair. 

How Long To Wait Before Bleaching Again?

Many people are so eager to get their hair color lighter that they often ask: “How many times can you bleach your hair in one day?”

Meanwhile, the question you should really ask is how long you should wait before the next bleaching attempt

The recommended break is three weeks before two consecutive bleaching sessions. This way, your hair cuticle has enough time to heal. If that’s too long for you, wait at least a week. 

If you don’t want to suffer unfortunate consequences, you’d better avoid bleaching your hair time after time within a short period.  

That said, those with dark hair who want to go blonde have to be very patient and make a lot of effort. You will have to undergo multiple bleaching sessions with three-week breaks between them. 

During each break, you also need to take very good care of your hair, including conditioning and pampering, to help it heal and recover before bleaching again. 

How To Bleach Your Hair At Home?

Prepare your hair before bleaching

The night before bleaching, remember to apply coconut oil to your hair to maintain moisture and reduce the influences of the bleaching process. 

Especially, between consecutive bleaching sessions, you need to apply virgin coconut oil to your hair every other day. Also, don’t use styling equipment and trim the split ends (if any).

Tips On Hair Care After Bleaching

Taking good care of your hair after bleaching will help it recover and stay healthy before dying or bleaching again. With that in mind, there are a few tips recommended for you.

Treat your hair gently

In the first week after the session, you shouldn’t use shampoo at all. Then, use a sulfate-free shampoo, avoid those that contain sodium lauryl sulfate, SLS, or sodium laureth sulfate. 

You can also use hydrating shampoos for cleansing as it ươn’t wash off the oil that protects your hair. When washing your hair, don’t scrub your scalp too hard. 

Once you’ve finished washing your hair, pat it dry using an old T-shirt or microfiber only. 

Deep condition your hair

Use the best conditioners for your hair. This way, your cuticle will be restored effectively, helping your hair become healthy and beautiful. 

Two things to remember, though. First, choose a conditioner that’s color-safe; secondly, let it sit and soak in when applying to your hair. 

Hydrate your hair

To maintain moisture, you can apply olive oil, coconut oil, argan oil, or almond oil to your hair and rub it gently. Hydration using these oils will also add shine to your hair. 

Besides, you can use hair masks made from honey, avocado, and egg white, which will make your hair soft and elastic. 

Stay away from heat stylers

Heat stylers like blow dryers and flat irons will further damage your bleached hair. This type of equipment sucks all the remaining moisture from your hair. 

Scalp massage

Scalp massage boosts hair growth and increases blood circulation to your head. You should massage your head whenever washing your hair, especially at the temples and the nape of the neck.

Wash hair with cool water

Washing your hair with hot water will open up the cuticle and further damage your hair strands.

You should wash your hair with cool or warm water only. Also, spritz cool water to your scalp before finishing to seal moisture. 

Trim off split ends

You should trim off 2-3 inches of the split ends. It will promote hair growth and help control the damage on bleached hair.
