Diaminopyrimidine Oxide is a hair growth active ingredient developed to address follicular degeneration and non-pathological hair loss. It is commonly used in anti-hair loss, hair regrowth, and hair density–enhancing personal care formulations.
By acting on dermal papilla cells and key follicular structures, Diaminopyrimidine Oxide improves the follicular microenvironment through multiple biological pathways. It supports the transition of hair follicles from the telogen phase to the anagen phase and helps prolong the active growth phase, contributing to visible improvements in hair density, strength, and overall hair vitality.
Why Choose Diaminopyrimidine Oxide?
Multi-Pathway Action on Hair Follicles
Rather than functioning as a simple stimulation agent, Diaminopyrimidine Oxide works on follicular structure, microcirculation, and cellular activity to comprehensively address hair loss concerns.
Designed to Target Follicular Fibrosis
Helps reduce abnormal collagen accumulation around hair follicles, softening fibrotic tissue and improving follicle elasticity, which is critical in preventing premature hair shedding.
Supports Prolonged Hair Growth Phase
Acts as a potassium channel opener, facilitating the shift from resting phase to growth phase and extending the duration of active hair growth.
Suitable for Global Formulations
Complies with cosmetic regulatory requirements in major markets including China, Europe, the United States, and Japan, making it suitable for export-oriented formulations.
