The curse of the gingers | Pharyngula

The curse of the gingers | Pharyngula: "But here’s the thing: pheomelanin is a lousy barrier to UV. In fact, pheomelanin is prone to photodamage (exposure to light causes it to break down) that produces carcinogenic byproducts. It’s also synthesized biochemically by a process that consumes glutathione (GSH), an important cellular anti-oxidant. So making red hair actually depletes the body of a protective substance, and has the side-effect of producing carcinogens. "
