From my understanding, hairloss comes from a variety of circumstances: genetics, nutrition, stress, etc. When it comes down to it, DHT blocks blood flow to the follicle, until the follicle eventually “dies.” Are there any products or studies being done to remove that blockage? If the blockage is removed, and blood flows back in, will the follicle grow hair again?
This is not an issue of blood flow to the follicle. Hair loss, when it occurs, reduces the demand for blood as the metabolic needs of the follicle are reduced when it becomes miniaturized. We know, for example, that if you put a normal hair follicle from the back of the head that has no genetic cause for its death, that hair will grow in the midst of thinning hair and when it grows it will be a thick, normal hair shaft. Your premise is incorrect, as DHT has little to do with blood flow directly.
