The most common form of hair loss

In both men and women, around 95% of all hair loss cases are caused by androgenetic alopecia (alopecia androgenetica, "AGA" for short). This inherent hair loss is the most common cause of alopecia in both sexes. The term "androgenetic alopecia" loosely translated means "hair loss due to male hormones". This is understood to be a form of hair loss that is triggered by a predisposition-related increased sensitivity of the hair follicles to male sex hormones (androgens). This is a genetically predetermined hair loss in which age plays an important role. The degree of androgenetic alopecia generally increases with age. It is also dependent on type-related and family predispositions. The hair roots develop a hypersensitivity to DHT (dehydrotestosterone), which comes from the body's own hormone testosterone. DHT shrinks the hair follicles, which restrict their production. The hair falls out faster. This applies equally to men and women. Usually this change begins between the ages of 30 and 40. It starts in the area of ​​the frontal cusps and at the top of the head. It comes to the well-known "receding hairline", which over time combine to form a bald head.

The difference between men and women

It is important to distinguish between androgenetic hair loss in men - also known as male baldness - and AGA in women. In men, the hormones cause, on the one hand, increased growth in the beard area, and, on the other hand, the proliferation of sebum glands on the head. The proliferation of the sebum glands is associated with the loss of hair. In men, complete baldness can occur in the final state, in women only a clearing of the main hair is created. In women, androgenetic alopecia is often associated with a masculine hair type. The affected women have hair on their lower legs, toes and face.

Treatment options

There are no effective measures to prevent androgenetic alopecia. How you care for and clean your hair does not in any way affect hereditary hair loss. Cosmetic hair restorers and what appears to be "miracle lotions" raise high hopes, but the effectiveness of these lotions, cures, hair lotions, creams, etc. for the treatment of hereditary hair loss has not been adequately documented. The earlier hair loss is detected, the sooner the treatment will be successful. Because the success is often only visible three months after the start of the treatment. Hair regrowth in already bald areas can only partially be achieved because the shrinking of the hair follicles in the context of androgenetic alopecia is generally irreversible. However, new drugs are making it possible to stop hair loss. The treatment methods are different for men and women. Alopecia can be treated in women with hormonal preparations such as hormonal contraceptives or topical products containing estrogen. In men, the genetic predisposition to hair loss can be treated with a relatively new active ingredient. The prescription drug contains the active ingredient finasteride, which is said to be able to stop hair loss in over ninety percent of men - if it is taken regularly. Finasteride inhibits DHT and thus blocks androgenetic hair loss. Long-term observations are still pending on this drug. But it is suspected of causing potency problems. Women are not allowed to take finasteride. The estrogens contained in hair lotions can have a relatively successful effect. They neutralize the effects of DHT in the scalp. However, if you stop using the agent, the hair will go out again. In addition, there is now a hormone-free solution for hereditary hair loss. Minoxidil solution has been approved for men in Germany for a long time, and since the beginning of 2004 also in a weaker version for use in women.

Hair replacement or hair transplant

Most of those affected do not need them, but wigs, toupees or hair transplants must be considered if nothing else works and the suffering is high. Various techniques are used during transplantation, e.g. the so-called autologous hair root transplant. A hairy area of ​​skin is removed under local anesthesia. This is then used again in bright or bare places. Alternatively, plastic hair can be implanted in the sparse area.
