  • Thinning or low-density areas needing targeted strengthening
  • Color-treated, highlighted, or chemically processed hair
  • Those seeking professional scalp treatments at home
  • Daily preventative hair strengthening routines

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.
