Double Trouble: Can You Bleach Your Hair Twice In One Day?

Dyeing hair is a trend that has lasted for years. But to experience the full intensity of the color, lightening or bleaching your hair strands is important, especially if you have darker hair. Hair color without bleach doesn’t quite have the same impact. 

But bleaching is a stressful process for your hair. In fact, if applied incorrectly, bleach can damage your damp hair.

Want to bleach your hair to stay up to date with coloring and highlighting trends? Here’s the ultimate guide that throws light on a key aspect: can you bleach your hair twice in one day?

Understanding The Mechanism Of Hair Bleaching

Bleaching involves using an oxidizing agent to strip the natural color of the hair strands. 

Once you bleach black hair, it acts on the melanin, a pigment that is responsible for lending the dark color. There are two types of melanin pigments: eumelanin which adds a black color, and pheomelanin, which adds a reddish hue. 

Bleach targets and oxidizes eumelanin and increases the intensity of pheomelanin. That’s why anyone with black hair has a reddish-orange hue post-bleach. If you leave the bleach longer, more melanin gets removed, resulting in a much lighter shade or a higher lift. 

Ammonia and Hydrogen Peroxide are popular bleaching agents.

Is Hair Bleaching Twice A Day A Good Idea?

Bleaching hair twice in one day is strongly discouraged due to potential stress and damage. For first-timers, a single session suffices for dyeing preparation.

 If a second bleaching is needed, wait at least 2 months to prioritize hair recovery. Repeated bleaching may result in a lighter base but risks frazzled and fragile strands. 

Can You Bleach Your Hair Twice In One Day Without Side Effects?

Common risks associated with bleaching hair twice in 24 hours include:

• Change in hair texture
• Increased porosity(1)
• Brittle and dry ends
• Redness and irritation on the scalp(2)
• Scalp burns

How Long Should You Wait Before Bleaching Again?

Maintain at least a 4 to 6-week gap before opting for another bleaching session. This window helps your hair to combat the negative effects of bleaching and restore the lost moisture.

The longer you wait, the better it is for your hair. Follow a consistent oiling and conditioning routine to help your hair be at its healthiest before it comes in contact with bleach a second time. 

Bleaching too frequently results in over-processed hair that breaks too quickly as the hair shaft doesn’t get any room to breathe or heal. 

How Many Times Can You Bleach Already Bleached Hair?

Technically, there is no limit on how many times can you bleach your hair that’s been bleached already.

However, that doesn’t automatically translate into a free pass to bleach your hair whenever you want to. Can you bleach your hair two times in a row? You can but you shouldn’t. 

Overbleaching can make your hair more fragile and prone to frizz. Ideally, wait for 4 to 6 weeks before bleaching your hair again. When you rebleach, only focus on the newly grown hair strands or your roots. Don’t apply bleach to your full head as that would mean exposing already bleached strands to more bleach, damaging them further. How to bleach hair twice in one day safely? It is best if you don’t!

What Is Double Bleaching?

Double bleaching refers to bleaching your hair twice on the same day. As tempting as it may sound, hair experts across the globe believe this is a dangerous practice. It can damage your hair irreparably and make it more fragile. 

How To Care For Bleached Hair?

Here are some handy tips to take care of bleached hair:

• Don’t skip the conditioner: Bleaching reduces the moisture and protein content of your hair. This makes it extra fragile and prone to dryness. Be generous with conditioning your hair and pay special attention to the ends. This is important for restoring shine and strength.
• Limit the usage of heat: A gorgeous blowout looks jaw-droppingly spectacular but it comes at a huge cost. Heat is not the kind of friend you would like your bleached hair to hang out with. Since bleached hair is already fragile and delicate, exposing it to more heat isn’t helpful. In fact, it can add to the dryness. If heat styling tools are an unavoidable part of your styling routine, don’t skimp on applying heat protection spray. 
• Try not to wash too frequently: Bleached hair is usually porous. Washing too frequently can increase porosity and make it more prone to frizz and breakage. Hair experts recommend washing it less often, so the natural hair oils can nourish and protect the strands.
