How Does A Keratin Treatment Work?

Keratin is an organic protein that makes up the structure of hair and skin. It is also found in nails, hooves, horns, claws, and feathers.

Keratin treatments work by sealing in moisture and locking in natural oils that keep your scalp healthy and prevent it from becoming dry and flaky [2]. The treatment also helps reduce frizziness and creates a smoother texture for your hair.

The keratin protein strengthens the bonds between strands of your hair. This prevents breakage, making your hair stronger and healthier looking.

Well, the truth is you can’t have the best of both worlds. If you want straight, manageable hair free of frizz, then you might have to risk your curls.

Keratin treatments are chemical + high heat treatments that open up the hair cuticle and smooth the curls. It also boosts shine, which is reduced by curls because the shine is caused by light bouncing off flat surfaces.

Keratin treatments are designed to dissolve the disulfide bonds inside your hair follicles. This chemical loss of disulfide bonds cannot be restored, and natural curls cannot exist without those bonds.

So, no matter how “gentle” or “safe” a keratin treatment purports to be, it’s crucial to understand that while your hair may seem smooth, glossy, and healthy after the treatment, your curls will be gone.

The good news is that it’s not permanent. After a few months, the chemically treated portions of your hair will grow out, and you will regain your curls.

According to Laura McGraw, curls specialist, “Damage can occur anytime the curls are chemically altered in any way, shape, or form.

That said, true damage can happen if the treatment is done poorly or a low-quality keratin product is used, resulting in hair breakage or unevenly altered curls”
