How to use

Apply Sérum Extentioniste directly to the scalp on cleansed, towel-dried hair.
Depending on hair type, 2 pipettes for fine hair and 4 for thick hair, position the pipette directly at the root and scalp to distribute 1 full pipette of the serum in a straight line from the front to the back of the head.
Follow the pipette with your fingers to massage the serum into the root and scalp as you work through each section.
Once application is complete in all sections, massage the entire head to distribute the serum evenly and comb through.
Leave in and proceed to blow dry.
Recommended to use at least 3 times a week.
