The serum is applied exclusively to the scalp! If the serum gets on the skin of the face and body, there will be an effect of redness and itching. 

How to do a sensitivity test correctly? 
Before using, apply the product to the hairy part of the skin behind the ear. If there is a comfortable reaction - use with pleasure! If there is an unbearable burning sensation, then the concentration of the serum is too high for you, so you should dilute it with water 1:1. The course of using the serum is from 3 months.
