How to use the shampoo most effectively?

Wet the hair thoroughly and apply the required amount of shampoo to the root, massaging with the soft fingers or using a scalp massager for 2-3 minutes, then rinse thoroughly with warm (not hot) water. Repeat if necessary. Finish with a Calinachi hair and scalp mask or conditioner.
*It is good to dilute 1:1 a sulfate-free shampoos with water beforehand to activate the foaming agent.
