Hair Serum & Hair Oil Application Tips
- Apply hair growth serum to a clean, dry scalp — for best results, apply directly to the scalp after washing and towel-drying. Massage gently with fingertips to stimulate circulation and boost absorption.
- Apply Olaplex No.7 to damp or dry hair — a few drops worked through mid-lengths and ends before blow-drying or styling delivers frizz reduction, heat protection and shine. A little goes a long way.
- Use argan oil as a finishing step — apply 1–2 drops of argan oil to dry hair as the final step in your styling routine for instant shine, smoothness and frizz control.
- Be consistent with growth serums — hair growth serums require daily, consistent use to deliver results. Most users see noticeable improvement in density and thickness within 8–12 weeks.
