We consulted the professionals to in finding out precisely how bleach works, its results at the hair, scalp, and pores and skin, and the way to give protection to your curl after lightening up.

What does bleach do, anyway?

It’s simple to put out of your mind simply how sturdy chemical bleach is when you are sitting for your colorist’s chair or purchasing a field of dye from the pharmacy. However, it doesn’t get advantages any person to forget about the truth that bleach is extremely poisonous.

These compounds are blended with liquid hydrogen peroxide to create bleach.

“When this composition is applied to hair, high concentrations of oxygen penetrate deep into the hair’s cortex and break down the melanin or natural color pigmentation. As the melanin granules are degraded, the hair becomes lighter in color,” explains Joseph Cincotta, a beauty chemist for Federici Brands (dad or mum corporate of Color Wow and Time Bomb). “Oxidation decolorizes the pigment in your hair shaft, which is why bleach will turn your hair almost white if it’s left on for too long,” explains Anabel Kingsley, a trichologist at Phillip Kingsley.

In order to create sufficient oxygen for oxidation to happen and successfully lighten the hair, activated bleach should have a top pH, which, as Cincotta issues out, is within the nine.five to 11.five vary. “When these disulfide bonds are exposed to the high pH level of active bleaching compositions, they can break. So, the unavoidable negative consequence of lightening hair is that your strands become weaker and less resilient,” he says. The response that happens between oxygen and the hair bonds is on the crux of all harm brought about by way of bleaching.

The harsh fact is that the extra often you bleach, the extra bonds are damaged, which has an impact at the look of your hair. “While all bleaches have a damaging effect on your hair’s protein structure, this is intensified each time the process is undertaken,” explains Kingsley.

The results of bleaching don’t seem to be restricted to the hair follicles, on the other hand, because the scalp, face, and neck are all normally uncovered to bleach throughout any colour carrier. “The high concentration of H2O2 and alkalizers in many bleaching products can cause blisters and burns on the skin,” says dermatologist Michelle Henry. Not most effective can this be all-around painful, it might probably additionally lead to transient or everlasting hair loss and scarring of the scalp. Though this feels like a nightmare state of affairs, it’s if truth be told extra commonplace than you assume. “Studies show that most hair stylists see transient scalp redness, even after routine bleaching treatments,” she notes.
