Androgenetic alopecia

Androgenetic Alopecia, also known as hereditary hair loss, is the most common cause of hair loss in men and women. It is characterized by progressive thinning of 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, general hair thinning across the entire scalp (female pattern hair loss) occurs without necessarily leading to complete baldness.

causes

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

Symptoms

In men, hair loss typically begins on the temples and top of the head and progresses 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 itself as a general thinning of the hair on the top of the head, while the hairline remains. Women are less likely to experience complete baldness than men.

diagnosis

The diagnosis of androgenetic alopecia is typically based on 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 or stop hair loss and promote hair growth. Options include:

Topical Uses : Minoxidil (Rogaine) is an over-the-counter medication suitable for men and women that may promote hair growth.
Oral medications : Finasteride (Propecia) is a prescription medication that inhibits the conversion of testosterone to DHT. It is only permitted for men.
Hair transplant : This surgical technique involves transplanting hair follicles from more hairy parts of the head to bald or thinning areas.
Laser therapy : Low-dose laser therapy can improve hair density in some people.

prevention

Because 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.
