Hereditary baldness is caused by follicle sensitivity to DHT.
Hormonal changes, stress, or nutrient loss can trigger shedding.
Alopecia areata is an autoimmune attack on hair follicles.
Blood flow and oxygen supply influence follicle recovery.
Treatments aim to reactivate dormant follicles or block DHT.
Microneedling and stem-cell research are expanding regrowth options.
Hair transplantation redistributes follicles, not new growth.
Balanced diets and reduced stress help maintain density.
