Diaminopyrimidine oxide is a chemical compound used to increase the volume of hair in the growth stage by working on the deep structure of the roots. It rejuvenates the hair roots so that healthy hair growth can persist. The perifollicular fibrosis is a condition in which collagen around the roots becomes rigid, tightens, and pushes the hair out. Diaminopyrimidine Oxide helps in softening of the collagen.
