  • After a keratin treatment, why might you start to get an itchy scalp? It’s because the formaldehyde derivatives the treatment contained dried and flaked your scalp. And that causes itching and irritation.
  • First of all, you should consult a dermatologist. They can do a complete study of your scalp to rule out an infection and recommend a treatment.
  • While you’re waiting for the appointment with the dermatologist, you can use certain shampoos and conditioners to soothe the itching, such as NIZAROL SHAMPOO. You can also use peppermint oil or rosemary water to treat itching.

Why your scalp feels itchy after a keratin treatment

A long time ago, but probably not as long as you might imagine, keratin treatments contained formaldehyde so their effects would last longer. The treated hair would be straight and frizz-free.

But in 2010, alarm bells started to ring around the world. It was discovered that many keratin treatments contained an excessive percentage of formaldehyde, which was extremely dangerous for your health.


Obviously, all keratin treatments containing a higher percentage of formaldehyde than what was allowed were withdrawn from the market.
