Most people prioritize dietary supplementation as the first reason to stop hair loss. This is true, but it is not enough. The solution is to stimulate microcirculation on the surface of the scalp by increasing the supply of nutrients to the hair bulb. In other words, apply serums, creams and shampoos topically, not just oral supplements.
In short, an effective hair treatment combines two treatment fronts: oral treatment through a food supplement + topical treatment.
