Use the dermaroller 3 times per week on a clean, dry scalp. Gently roll it back and forth over areas of concern—front hairline, temples, crown—for about 5 minutes total. Apply light, even pressure without dragging.
On dermaroller days, do not apply The Hair Multiplier immediately before or after. Instead, allow your scalp to rest and resume serum application the following day. This helps avoid irritation while still supporting consistent results.
For hygiene, always disinfect your dermaroller with rubbing alcohol before and after use.
