Definition
The various types of alopecia can be divided into:
- non-cicatricial forms (temporary forms of alopecia with transient functional inhibition of the hair papilla). Examples are androgenetic alopecia, post-pregnancy, malnutrition, psychophysical trauma, alopecia areata, traction alopecia, iatrogenic (from drugs), etc .;
- cicatricial forms (forms of definitive alopecia with disappearance of the follicle and germinative papilla). Examples are scleroderma, discoid lupus erythematosus, lichen planus, decalvenous folliculitis, mycoses, neoplasms.
Androgenetic alopecia is the main cause of thinning of the scalp. In the course of life it affects about 80% of the male population and 50% of the female population.
