    TLDR Commercial hair dyes can harm the skin and liver.
    The study "Some histological and biochemical evaluation on commercial hair dyes" conducted by Stanley Obialor Anyanwu, Agala Egbe, and Iwaeni Bassey Eborty-Ike, aimed to assess the toxicity of different commercial hair dyes on the skin and liver of Albino rats. The study, conducted between May and October 2019, involved 20 male Albino rats, divided into five groups of four. Four different hair dye colors were applied topically on the rats for 30 days, after which the rats were sacrificed for histological and biochemical analysis. The results showed that the serum levels of Alkaline phosphatase (ALP), Aspartate Amino transferase (AST), Total protein (TP), Total bilirubin (TB), and conjugated bilirubin (CB) in all the test groups were significantly increased compared to the control group (P=0.001). Histological evaluations indicated evidence of cellular injury in all the test groups. The study concluded that prolonged use of commercial hair dyes caused adverse effects to the skin and liver.

      The conversation suggests that changing diet and lifestyle has little to no effect on male pattern baldness (MPB), which is largely determined by genetics. Some individuals noted personal improvements in hair condition with healthier diets, but the consensus is that diet alone cannot prevent or reverse MPB.
