HOW TO USE

HOW TO USE

Apply 4 doses on dry or towel-dried scalp, section by section. 1 dose = 1 pipette until the mark. Do not rinse.

When choosing where to apply the sèrum think of the areas of your scalp where the hair needs the most strength. Where do you notice less density? What areas are you experiencing hair fall in? Start by applying in those targeted areas with the pipette then massage in everywhere. Think of the serum like topical vitamins for your hair!
