Why should I wash my hair with Thymuskin Shampoo before using Thymuskin Serum?

Thymuskin Shampoo and Thymuskin Serum are coordinated preparations.

The function of each Thymuskin Shampoo is to gently cleanse the scalp and optimally prepare it for subsequent use with the Thymuskin Serum.

It is not necessary to wash your hair every day. However, deposits of all kinds and dead skin cells also collect on the scalp, which should be removed at least 1-2 times a week.
