Hair Regrowth Treatment

Regrowth Labs D5a is a pharmaceutical-grade hair regrowth treatment containing the highest purity Dutasteride USP 0.5% and Azelaic Acid, two powerful and clinically proven 5α-reductase inhibitors that prevents conversion of testosterone to dihydrotestosterone (DHT). Propanediol, a Propylene Glycol alternative, reduces skin irritation and delivers optimum absorption. D5a treats the entire scalp against hair loss--both the vertex and hairline.


Science Matters

  • Dutasteride 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.

  • Azelaic acid inhibits dihydrotestosterone (DHT) and prevents hair loss.

  • 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.

  • Trichogen decreases hair loss and stimulates hair growth, stimulates metabolism, and improves cellular oxygenation and skin/scalp microcirculation.

  • This formula combines proprietary nanosome encapsulation technology and transdermal enhancers to ensure deeper penetration and delivery without alcohol and propylen glycol.

  • D5α contains no petroleum/petroleum, no mineral oil/paraffin liquid, no fragrance, no sulfate and is parabens-free.
