Types of keratin hair treatments

In the hairdresser, keratin is used in two types of treatments: hair reconstruction and smoothing, the latter not to be confused with chemical straightening or permanent straightening.

The substantial difference lies in the fact that keratin does not affect the structure of the hair, but only modifies its shape, smoothing it without damaging it.

Which of the two treatments to ask? It depends on the type of hair: if they are only damaged and straight, reconstruction is sufficient; if they are wavy, curly or very frizzy, it is better to opt for the straightening treatment. In some cases, it is necessary to first rebuild and, after a month, proceed to smooth the hair with keratin.

With a brush, the product is applied to each strand starting from the root, and then a fine-toothed comb is passed to distribute the product over the lengths. Leave on for 30 minutes. It is dried with a hair dryer, and the plate is passed on each single strand from 6 to 8 times with a temperature ranging from 200 ° C to 230 ° C (it all depends on the diameter of the hair and how much you want to straighten).

We then proceed to a light wash without conditioner and you should avoid washing your hair for the next 48 hours. This type of treatment lasts between 3 and 5 months. The cost is around € 100, although a lot depends on the length of the hair.
