The Follicle Revitalizer for Intensive Anti-Hair Loss and Regrowth Support
Pyrrolidinyl Diaminopyrimidine Oxide is a high-performance cosmetic grade active and a benchmark in modern trichology. Closely related in structure to Minoxidil, it acts as a potent follicle revitalizer that increases blood flow to the scalp and reverses the shrinkage of hair follicles. By improving nutrient delivery and oxygenation, it effectively reduces hair shedding and stimulates the growth of thicker, stronger hair.

In the advanced medical-aesthetic hair care sector, addressing non-scarring alopecia without triggering scalp irritation is the ultimate formulation challenge. Our premium Cosmetic-Grade Pyrrolidinyl Diaminopyrimidine Oxide is rigorously engineered to completely remove pharmaceutical impurities. Built to be 100% farnesol-free, it establishes a flawless safety profile that eradicates the risk of ingredient-induced sensitization on hyper-reactive scalps. By stimulating scalp microcirculation and extending the anagen (growth) phase, it acts as a highly potent follicle anchor that halts thinning and promotes the emergence of healthy “baby hairs” without the itching or dryness associated with traditional pharmacy treatments.
For Global OEM/ODM Innovators: Achieve ultimate formulation elegance and extreme compatibility. Our ultra-fine crystalline powder dissolves flawlessly into your solvent phase (Ethanol or Propylene Glycol), yielding a crystal-clear, water-white, and entirely odorless profile. It ensures zero greasy residue and guarantees it will never compromise the precise color, fragrance, or aesthetic of your final hydro-alcoholic tonics. Exceptionally stable and easy to process, it completely eliminates manufacturing friction for your R&D teams.
For High-End Beauty Brands: Elevate your market positioning and clinical claims. This ultra-pure active is the signature choice for strict “Clean Beauty” mandates and highly tolerable “SOS Emergency Repair” scalp formulations.

Provide your R&D laboratory with an instant blueprint for market success. Our Pyrrolidinyl Diaminopyrimidine Oxide acts as a supreme biological growth stimulator, protecting and amplifying the restorative efficacy of companion actives for total scalp and follicle health:
Pyrrolidinyl Diaminopyrimidine Oxide + Allantoin: The ultimate post-damage clearing and growth matrix. Combines the targeted vasodilation and follicle anchoring of our active with the water-soluble wound-healing properties of Allantoin to rapidly clear micro-traumas and instantly soothe inflamed, thinning scalps.
Pyrrolidinyl Diaminopyrimidine Oxide + Panthenol: A comprehensive “SOS Barrier Rescue” and follicle-strengthening system. Panthenol floods the stratum corneum with deep, targeted hydration, creating a healthy, non-reactive scalp environment that allows our active to effectively extend the anagen phase and thicken the hair shaft without triggering dryness.
Pyrrolidinyl Diaminopyrimidine Oxide + Ceramide NP: The absolute defense and structural longevity complex. While our active tackles internal follicle miniaturization from within, Ceramide NP safely and physically rebuilds the scalp’s depleted lipid cement on the surface, ensuring a resilient, balanced, and perfectly protected environment for new hair emergence.
