This review discusses cellular plasticity in skin and intestine, hypothesizing that mature cell reprogramming might contribute to tumorigenesis, and reports no new clinical results.
Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.
Collagen peptides are recommended for hair and skin benefits, with users noting improvements in hair and skin health. However, evidence on their effectiveness for hair growth is inconclusive.
Minoxidil may improve or worsen skin quality, with topical forms causing dryness and wrinkles, possibly due to alcohol content, while oral forms have fewer side effects. Some users consider using tretinoin to mitigate negative effects.
Finasteride and minoxidil use resulted in a more youthful appearance and improved skin. There is debate about their effects on collagen and skin aging, with no solid evidence supporting significant changes due to finasteride.
GHK-Cu peptide injections are discussed for hair growth, but users report mixed results and suggest focusing on DHT management first. Some users combine GHK-Cu with treatments like Minoxidil and Dutasteride, but emphasize its benefits for skin rather than hair.
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.
