Hormony, vodi\u010de ochlupen\u00ed na t\u011ble<\/h2>\n

R\u016fst vlas\u016f je prim\u00e1rn\u011b ovlivn\u011bn androgeny, co\u017e je skupina hormon\u016f, kter\u00e1 zahrnuje i testosteron.

Jeho role se nejv\u00edce projevuje b\u011bhem puberty. Pod jeho vlivem se jemn\u00e9 chlupy pokr\u00fdvaj\u00edc\u00ed t\u011blo mohou v ur\u010dit\u00fdch oblastech, jako je obli\u010dej, hrudn\u00edk, pa\u017ee nebo z\u00e1da, vyvinout v siln\u011bj\u0161\u00ed, tmav\u0161\u00ed a odoln\u011bj\u0161\u00ed chloupky. P\u0159ekvapiv\u00fd detail: v\u0161ichni, nebo t\u00e9m\u011b\u0159 v\u0161ichni, m\u00e1me stejn\u00fd po\u010det vlasov\u00fdch folikul\u016f.
