DHT (dihydrotestosterone) hair loss, also known as androgenetic alopecia or male pattern baldness, is a common type of hair loss that affects both men and women. DHT is a hormone derived from testosterone, and it plays a role in the development and growth of hair follicles. However, in individuals with a genetic predisposition, DHT can have a negative impact on hair follicles, leading to miniaturisation and eventual hair loss.
Hair follicles in certain areas, such as the temples, crown, and frontal hairline, become genetically sensitive to the effects of DHT. When exposed to DHT, these sensitive hair follicles gradually shrink in size and produce thinner, weaker hair strands. This process is called miniaturisation. Over time, the affected hair follicles produce increasingly smaller and finer hair until they eventually stop producing visible hair altogether. This leads to the appearance of thinning hair and, in some cases, baldness. While DHT hair loss is primarily associated with male pattern baldness, women can also experience it, although the pattern of hair loss may differ.
The FDA-approved medications like minoxidil (Rogaine) and finasteride (Propecia) which can help slow down hair loss and promote hair regrowth in some individuals. These medications work by either stimulating hair follicles or inhibiting the conversion of testosterone to DHT.
For individuals with advanced hair loss, hair transplant procedures can be considered. This involves transferring hair follicles from donor areas to areas of thinning or baldness.
Some individuals may benefit from low-level laser therapy devices, such as laser combs or helmets, which can stimulate hair growth.
It’s important to note that results can vary from person to person, and it’s best to consult with a dermatologist or a healthcare professional specialising in hair loss to determine the most suitable treatment options for your specific situation.
