Hair loss is primarily caused by genetics and hormones like DHT that make hair follicles sensitive to changes in hormone activity, causing gradual hair loss known as androgenetic alopecia. Effective hair loss treatments block hormones like DHT from reaching hair follicles while also stimulating hair growth. Topical creams containing anti-androgens can stop sensitive hormones and help hair growth. It is important to understand what causes hair loss and how different treatments work before finding a pure herbal treatment without harmful chemicals.
