Types of alopecia:
Also known as baldness, it is the most common in men; 80-90% of cases of alopecia. It is produced mainly by genetic causes, hereditary, because of age and, especially, by male hormones (androgens). You can inherit both father and mother and it can start at any age, from puberty.
The degree of sensitivity to dihydrotestosterone (DHT) is a natural metabolite (substance produced by the body or used when food, drugs or chemicals break down, or their own tissues such as fat or muscle tissue. called metabolism, produces the energy and materials necessary for growth, reproduction, maintenance of health and elimination of toxic substances) of the male hormone testosterone causes weakening of the follicle. DHT causes hair atrophy, hypertrophy of the hair sebaceous gland and a decrease in hair density, thinning and losing color.
DHT first causes a shortening of the growth phase of the capillary cycle, which leads to the miniaturization of the hair and finally the hair becomes thin, short, colorless, leaving less and less hair on the head.
To fight against this, there are only two products, a topical (minoxidil) and an oral (finasteride). The 3rd option, definitive, is the hair transplant.
