Androgenetic alopecia

It is one of the most common reasons for hair loss in case of men. The process is the consequence of the influence of testosterone derivate (dihydrotestosterone) on genetically predisposed connective tissue hair sheaths. As a result, the hair previously thick is becoming thinner leading to the final disappearance of connective tissue hair sheaths. Although the process is induced by testosterone, in majority of cases the level of this hormone in antitoxin usually stays within the limit of the normal range. The problem concerns both men and women.

In case of men:

The first symptoms of male–pattern hair loss may appear in teenage years. The predisposed areas include a temple, a forehead and in case of some patients – the top area. In some cases the male-pattern hair loss may include skin on the whole head. However, in majority of cases, thickness of hair on an occipital area remains unchanged, which results from lower androgen responsiveness of connective tissue hair sheaths in this part of a head.

In case of women:

Female-pattern hair loss may have various clinical pictures. It appears, most often, in the parietal area and is characterized by a widening parting in a form of so called “holiday tree” (thinning of hair is more visible in the area of a forehead and less visible on the area leading to the top of the head). Female-pattern hair loss is less common in the area of the top of a head or connected only to moving back the line of hair in the temporal area. In some cases, female-pattern hair loss may be the symptom of hormone dysfunctions such as polycystic ovary syndrome (PCO), insulin resistance or metabolic syndrome.

In trichoscopy, in predisposed areas as to occipital one, significant hair thinning is visible as well as numerous single hair.

In curing both men and women what is used are topically administered minoxidil preparations and given orally 5-α-reductase inhibitors: finasteride and dutasteride. Additionally, carboxytherapy and mesotherapy treatments with the use of platelet-rich plasma or minoxidil may be used.
