7 misstag som förkortar din keratinbehandling

When a keratin treatment fades prematurely, it is rarely because of the product. It is almost always one of these seven things.

1. Skipping the deep cleanse

Without clarifying shampoo, the keratin adheres to product residue instead of the hair shaft.

2. Moisture left in the hair

The hair must be completely dry during application, not almost dry.

3. Washing too soon

72 hours is not a guideline. If you wash after one day, you have effectively rinsed away part of the treatment.

4. Sulfates in the shampoo

The most common mistake of all. Switch to sulfate-free shampoo and sulfate-free conditioner from the first wash. Also check your dry shampoo and purple shampoo, as they are often forgotten.

5. Washing too often

Every wash removes a little of the treatment. Every other day to every third day is ideal.

6. Chlorine and salt water

A week of daily pool swimming can reduce the treatment's longevity by a month. Wet your hair with fresh water and apply conditioner before swimming.

7. Not replenishing it

Keratin fades gradually. A treatment with Cocochoco Keratin Repair Mask once or twice a week maintains the level and noticeably extends the period.
