HOW TO USE

Expert Application Guide

  1. Towel-dry hair after cleansing with shampoo and conditioning
  2. Fill pipette to the black dosage line — this equals one dose
  3. Part hair and apply directly to scalp — focus on areas prone to breakage or where you notice lower density
  4. Massage into scalp to ensure full absorption
  5. Apply up to 4 doses total, targeting problem areas section by section
  6. Do not rinse — proceed to blow dry or let hair air dry and style as usual

Pro Tip: For maximum cooling and calming benefits, store your serum in the refrigerator prior to applying.

Between Washes: Can also be applied to dry scalp on non-wash days for continuous strengthening protection.

 


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!
