Hair loss is a condition in which genetic factors play an important role. Genetic predisposition affects an individual’s propensity for hair loss and determines susceptibility to male pattern baldness or other types of hair loss. One of the main factors affecting the success of hair transplantation is genetic characteristics. Therefore, it is important to understand genetic factors to deal with the hair loss problem and plan an effective hair transplant. In this content, we will take a closer look at the role of genetics in hair loss and its effects on hair transplantation success.
What is Genetic Hair Loss?
Genetic hair loss, also known as androgenetic alopecia, is a hereditary condition characterized by a gradual and predictable pattern of hair loss. It is the most common cause of hair loss in both men and women. The term “androgenetic” implies that genetic and hormonal factors contribute to the development of this condition.
In individuals genetically predisposed to androgenetic alopecia, hair follicles are sensitive to dihydrotestosterone (DHT), a hormone derived from testosterone. Over time, exposure to DHT causes hair follicles to shrink, leading to shorter and finer hair growth cycles. Eventually, the affected follicles stop producing new hair altogether, resulting in visible thinning and, in some cases, balding.
Genetic hair loss typically follows a specific pattern. In men, it often begins with a receding hairline and thinning at the crown, forming an “M” shape. Women with androgenetic alopecia typically experience diffuse thinning across the crown of the scalp, rather than specific patterns.
While genetic hair loss cannot be completely prevented, various treatments, including medications like minoxidil and finasteride, as well as surgical options like hair transplantation, can help manage the condition and promote hair regrowth.
