4-In-1 Hair Growth Serum – Rosemary, Batana, Castor Oil & Biotin (50Ml)

The 4 most sought-after hair loss actives, in one bottle

Rosemary or batana? Castor oil or biotin? Don't choose: this serum concentrates the 4 ingredients most backed by the hair care community in a lightweight, fast-absorbing, non-greasy formula.

The formula

• Rosemary oil — the classic, with studies on mild hair loss
• Batana oil — deep follicle nourishment
• Castor oil — density and strength for fine hair
• Biotin — the essential building block of keratin

How to use

Using the dropper, apply daily to lower-density areas (best: load it into the reservoir of your red light comb). Massage for 3-5 minutes. 50 ml bottle ≈ 6-8 weeks.

What to expect

Less shedding in the shower around weeks 6-8; visible density with 12 weeks of consistency. No overnight results — and anyone who promises you that is lying.
