Product Details

SP2 Hair Regrowth Treatment is a specialized topical formula designed for individuals with sensitive scalps who want targeted support against androgenetic alopecia (male and female pattern hair loss). Featuring an androgen receptor antagonist, SP2 is formulated to help reduce the effects of DHT (dihydrotestosterone) by limiting its interaction with hair follicles at the receptor level.

Unlike treatments that work by altering hormone production, SP2 is designed to act locally on the scalp, making it a gentle option for those seeking a DHT-targeting solution with a focus on scalp comfort. Its carefully balanced formula helps create a healthier environment for hair follicles while minimizing the risk of irritation commonly associated with stronger topical treatments.

Developed as one of the gentlest DHT-focused options in the Regrowth Labs line, SP2 supports healthier-looking hair by helping preserve follicle function, maintain scalp balance, and promote a comfortable daily treatment experience. The lightweight, fast-absorbing formula is suitable for long-term use as part of a comprehensive hair restoration routine.

Key Benefits
  • Helps reduce the effects of DHT at the hair follicle receptor level.
  • Designed specifically for sensitive scalps.
  • Gentle, irritation-conscious formulation for everyday use.
  • Supports healthier hair follicles and overall scalp health.
  • Helps maintain an optimal scalp environment for hair growth.
  • Lightweight, non-greasy, and fast-absorbing formula.
  • Can be incorporated into a comprehensive hair restoration routine.
  • Suitable for long-term topical scalp care.
How to Use
  1. Apply the recommended amount directly to clean, dry areas of the scalp affected by hair thinning.
  2. Gently massage until the solution is evenly distributed and absorbed.
  3. Allow the product to dry completely before applying other hair products.
  4. Use consistently as directed by your healthcare provider or according to the product instructions.
Ideal For
  • Individuals with sensitive scalps.
  • Men and women experiencing androgenetic alopecia.
  • Those seeking a gentle topical DHT-targeting treatment.
  • Users who want to minimize scalp irritation while supporting healthy hair growth.
Caution
For external use only. Avoid contact with the eyes and damaged skin. If irritation or an allergic reaction occurs, discontinue use and consult a healthcare professional. Keep out of reach of children.
