Superoxide dismutase (SOD) can prevent hair graying in mice.
research Dopa oxidase activity in the hair, skin and ocular melanocytes is increased in the presence of stressed fibroblasts
Stressed fibroblasts greatly increase melanin production in hair, skin, and eye cells, mainly due to a growth factor called bFGF.
research The Oxidative Degradation of Keratin (Wool and Bovine Hair)
Oxidizing agents break down keratin in wool and hair, causing swelling and increased solubility.

Hair plucking quickly increases antizyme, reducing a specific enzyme activity in rats.
research Evaluation of oxidative stress, 3-Nitrotyrosine, and HMGB-1 levels in patients with wet type Age-Related Macular Degeneration
wAMD patients have higher oxidative stress, suggesting antioxidant treatment may help.
research The Case Files
The man's skin condition improved with sun protection and topical steroids, but UV exposure still caused flare-ups.
research Sulphation catalysed by the human cytosolic sulphotransferases - chemical defence or molecular terrorism?
Human enzymes can detoxify harmful substances but might also increase their cancer risk.
research Ingestion of minoxidil associated with elevated transaminases in the absence of ischemic hepatitis
Minoxidil ingestion can raise liver enzyme levels.
research Determination of rat 5α-reductase type 1 isozyme activity and its inhibition by novel steroidal oxazolines
