Aminexil (diaminopyrimidine oxide)

2-4 Diamino Pyrimidine-3-Oxide) is a similar compound to Minoxidil that prevents premature aging or rigidification of collagen, but without the possible side effects (scalp irritation, redness, itching).

Is it safe?  Are there side effects?

There are none directly associated with this topical solution. At present, the SCCNFP does not recommend any specific warnings or restrictions under the currently proposed conditions of use 


Through the softening and improvement of elasticity to this collagen structure, micro capillary blood flow to the follicle is enhanced allowing stronger and more vigorous hair growth, particularly in follicles that are becoming compromised. Clinical Trials have demonstrated that Diamino Pyrimidine Oxide) preserves and strengthens hair fibres. In a Trial involving over 100 men it was shown to slow hair loss after 3 weeks and maintain an additional 8% of hair in the growth (anagen) phase after 6 weeks. A solution containing 1.5% 2,4-DPO in ethanol/water at least three times a week.


Originally developed by a French company named Vichy.


Inhibits Lysyl Hydroxylase, an enzyme participating in the maturation and hardening of the collagen structure of the hair follicle.

  3. Why Hair is Important 2 Kareena Kapoor-Top Bollywood actress Although Hair is dead tissue, but play a very important role to enhance the beauty
  4. Hair Science • Hair is made of a structural protein called keratin. • Two major parts: A) Hair Shaft B) Hair follicle or hair bulb. • At the base of the follicle is the dermal papilla, feed by the bloodstream which carries nourishment to produce new hairs. 3
  5. Any change in Hair growth cycle leads to hair loss, is a common problem affecting both men and women. • Hair loss is a multi-factor disorder, happened due to below given reasons. • Shrinkage of hair follicles. • Gradual increase in telogen phase • Reduction in A:T ratioResults in hair loss and visible baldness Hair Loss 4
  6. 5 Market Potential of Hair Care products •Global Hair Care Products Industry Revenue is Forecast to Reach an Estimated $82.2 Billion in 2018 . • The global hair care products industry mainly comprises the manufacturers of all hair care products such as shampoos, conditioners, hair oils, hair colorants, hair treatment products, and hair styling products. • Europe dominated this industry with the highest market share of approximately 43%, followed by Asia Pacific. • Asia Pacific has emerged as the fastest-growing region in the industry.
  7. FDA approved hair growth stimulants 6 • Minoxidil and Finasteride are only FDA approved molecules for Hair growth, comes under schedule H and cannot be used for cosmetic applications. • Minoxidil is treated as a gold standard but it is insoluble in water and containing high concentrations of alcohol which makes scalp dry and resulting in dandruff. • Minoxidil also affects on blood pressure, so not ideal for BP patients. • Kumar organic R&D team developed the innovative hair growth molecule which is 100 % soluble in water and having strong anti-oxidant property.
