Hair Regrowth Treatment

Regrowth Labs FIN25 is a pharmaceutical-grade hair regrowth treatment containing the highest purity Finasteride USP 0.25%, a powerful and clinically proven 5α-reductase inhibitor that prevents conversion of testosterone to dihydrotestosterone (DHT). Propanediol, a Propylene Glycol alternative, reduces skin irritation and delivers optimum absorption. FIN25 treats the entire scalp against hair loss--both the vertex and hairline. 


Science Matters

  • Finasteride works as a type II and type III 5α-reductase inhibitor; 5α-reductase, an enzyme, converts testosterone to dihydrotestosterone (DHT), the powerful androgenic hormone that causes damage to hair follicles in men.
  • Propanediol is a natural, plant-based, skin-friendly, preservative-boosting alternative to petroleum-based Propylene Glycol. With no irritation, enhanced moisturization and excellent aesthetics, Propanediol is ideal for hair care products. Importantly, it is also used as a high-performing carrier for actives and botanical extracts.
