The 5-alpha reductase inhibitor finasteride promotes the growth of these structures. Horny, flattene
The 5-alpha reductase inhibitor finasteride promotes the growth of these structures. Horny, flattened, nucleated cells can be found in Huxley's layer, and cubical cells with clear, flattened nuclei make up Henle's layer, in these structures. These structures grow during the anagen phase, stop growing during the catagen phase, and rest during the telogen phase. Fetuses and newborns possess a type of these structures known as lanugo.
