When it comes to hair regrowth, dermatologists generally recommend Procapil or Minoxidil. Minoxidil has been prescribed for years but is now becoming a lesser-favored choice due to its side effects. Compared to it, Procapil is derived from plant-based ingredients and has no side effects. When you pick a Procapil-enriched hair serum like Nutrex Hair, you are choosing an FDA-approved formulation that has NO harmful side effects of Minoxidil, like itching, dryness, irritation, and initial shedding that could really scare many people off.
