DHT (dihydrotestosterone) is one part of the biology behind androgenetic, or pattern, hair loss. It is not the cause of every type of shedding. Understanding that difference helps you choose hair care more intelligently.
What Is DHT?
DHT is an androgen made from testosterone. In genetically susceptible hair follicles, androgen signalling can gradually miniaturize follicles. This can appear as a receding hairline or crown thinning in men, and a widening part or diffuse thinning in women.
Does Every Case of Hair Fall Come From DHT?
No. Hair shedding can also follow illness, major stress, rapid weight loss, pregnancy and postpartum hormonal changes, nutritional deficiencies, scalp conditions, medications and physical hair damage. If shedding is sudden, patchy or rapidly progressing, professional assessment is more useful than assuming DHT is the cause.
What Are DHT-Blocking Ingredients?
Some cosmetic products use botanical ingredients such as saw palmetto and pumpkin seed oil because laboratory and limited human research suggests possible effects on androgen pathways. However, evidence for topical cosmetic formulations is still developing and should not be described as equivalent to prescription treatment.
What About Minoxidil?
Minoxidil is a medicine with evidence for certain types of pattern hair loss. It works differently from a DHT-blocking ingredient. Some users experience irritation or an initial increase in shedding, and ongoing use is generally needed to maintain benefit. A clinician can help determine whether it is appropriate.
