PARIETAL AND OCCIPITAL HAIR LOSS PATTERNS IN INITIAL STAGES OF ANDROGENIC ALOPECIA IN MEN

Background: The initial stages of androgenetic alopecia in men are characterized by a variety clinical manifestation the parietal or occipital scalp regions. However, differences pathogenesis hair loss patterns not well understood, selective treatment has been developed.
 Aims: Trichological characteristics patients with identification genetic and non-genetic factors that determine different regions, their response to conservative therapy.
 Materials methods: Trichograms were photodocumented using an AramoSG microcamera (Republic Korea). factor was analyzed mini-sequencing single nucleotide polymorphisms rs929626, rs5919324, rs1998076, rs12565727, rs756853. study included hormonal status (total free testosterone, dihydrotestosterone, 17OH-progesterone, dehydroepiandrostenone, SHBG) blood content trace elements (Mg, Ca, Zn, Cu, Se, Fe) vitamins (B12, D, E, folic acid). Conservative topical application minoxidil 5% (twice-a-day, 4 months) micronutrient deficiencies personalized correction.
 Results: 47 man alopecia. Their trichological examination showed two patterns, consisting predominant decrease density diameter which subgroups formation criteria. An intergroup comparison revealed similar risk, while parameters (increased dihydrotestosterone levels, testosterone) subgroup pattern. Also, multiple deficiency Se B12, acid detected all patients. Subsequent had positive effect pattern, pattern no significant observed.
 Conclusions: develops ideas about between androgen-dependent androgen-independent alopecia, requires approaches therapy.
