This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.
This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This review discusses transplantation of melanocyte stem cells for vitiligo treatment and reports no new clinical results; it suggests the procedure could be effective in reactivating melanocyte precursors for repigmentation.
Exosomes combined with fractional picosecond laser treatment were effective in treating androgenetic alopecia and promoting repigmentation in white hair patches. The role of exosomes in hair repigmentation, particularly in conditions like poliosis, is not well-studied.
Balancing hormones, particularly testosterone and DHT, may prevent hair loss and slow aging. Treatments include finasteride, dutasteride, zinc, magnesium, collagen, and natural DHT-blocking shampoos.
Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.
RT1640, a combination of cyclosporin A, minoxidil, and RT175, is discussed as a potential treatment for hair regrowth and repigmentation. The unique formulation aims to enhance hair follicle growth and restore hair pigment without the negative side effects of immunosuppressants.
Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.
Is scalp micropigmentation suitable for people with sensitive skin?Providers say scalp micropigmentation suits most skin types and describe patch tests, hypoallergenic pigments and a skin consultation for sensitive skin. These are provider claims rather than independent safety evidence, and pigment reactions remain a risk.
