Androgenetic alopecia

Androgenetic asteroids AlopeciaHereditary hair loss, also known as male pattern baldness, is the most common cause of hair loss in both men and women. It is characterized by a progressive thinning of the hair in a characteristic pattern caused by genetic and hormonal factors. In men, this condition is often referred to as male pattern baldness, while in women, it is characterized by general thinning of the hair across the entire scalp (female pattern hair loss), without necessarily leading to complete baldness.

causes

Androgenetic alopecia is caused by a combination of genetics and the influence of male factors Hormones, caused by androgens. A key role is played in this Dihydrotestosterone (DHT), a metabolite of testosterone. DHT binds to androgen receptors in the hair follicles, leading to a reduction in hair size in genetically predisposed individuals Hair follicles This process, also called miniaturization, shortens the growth phase of the hair (Anagen phase) and leads to thinner, shorter hair and eventually to the loss of this hair.

Symptoms

In men, hair loss typically begins at the temples and crown, progressing to an M-shaped hairline and a bald spot on the head. Over time, this can lead to complete baldness, except on the sides and back of the head.
In women, androgenetic alopecia usually manifests as a general thinning of the hair on the top of the head, while the hairline remains intact. Women experience complete baldness less frequently than men.

diagnosis

The diagnosis of androgenetic alopecia is typically based on the clinical presentation and family history. A doctor may also perform a scalp biopsy to rule out other causes of hair loss.

Treatment

The treatment aims to slow down or stop hair loss and promote hair growth. Options include:

Topical applications : Minoxidil (Rogaine) is an over-the-counter medication suitable for both men and women that can promote hair growth.
Oral medication : Finasteride (Propecia) is a prescription drug that inhibits the conversion of testosterone to DHT. It is only approved for use in men.
Hair transplantation : In this surgical technique, hair follicles are transplanted from densely haired areas of the head to bald or thinning areas.
Laser therapy : Low-dose laser therapy can improve hair density in some people.

prevention

Since androgenetic alopecia is primarily genetic, there are no known methods for prevention. However, early treatment can help slow hair loss and maintain or improve hair density.

It is important to seek medical advice if you experience signs of hair loss in order to make a correct diagnosis and determine the most appropriate treatment.
