A multi-botanical hair growth serum blending rosemary, batana, castor oil, and rice water with biotin. Positioned as a thickening and growth-support treatment for women and men. Comes as a 2-pack of 1.7 fl oz bottles with dropper application. The formula targets the appearance of fuller, faster-growing hair through scalp circulation and hydration claims.

Key actives: rosemary (circulation), castor oil (conditioning), rice water (protein), biotin (hair strength). Growth claims are primarily anecdotal—no clinical data provided. Amazon reviews (mid-4.0s) cite modest scalp hydration and light texture, though some report minimal visible growth. The lightweight feel suits most hair types, but efficacy hinges on consistent use over weeks. Better suited as a scalp hydration and sealing oil than a clinically proven growth accelerant.
