As a growth serum: apply to the scalp as regularly as possible using circular movements to activate blood circulation and thus stimulate growth. Do not rinse.
In oil bath: apply to damp hair from scalp to lengths. Leave on for a minimum of 30 minutes under a heated cap. Rinse and then proceed with your usual washing routine.
As a finishing oil: apply at the end of your styling routine. A few drops are enough to seal in the moisture. No rinsing required.
