Nitric oxide is important for skin functions and both helps protect against and contributes to skin inflammation and sensitization.

CD4+ skin cells may be precursors to basal cell carcinoma.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
