I have had diffuse alopecia for about ten years. My hair was a very dark brown, and now my hair is losing it's pigment and is sort of reddish. Is this something typical of alopecia? Has this happened to anyone else? I also notice a weird pigment pattern on strands of hair....like dark brown and then almost white and then brown again.

Hi Heather,

Yes, it's crazy but it happens. The way we get normal hair pigment is due to the relative percentage of eumelanins and pheomelanins ( proteins) that we have. Any disruption to the normal process in which amino acids are activated in the presence of certain enzymes and a major color change can result. It's all bio- chemistry.

According to a study published in 2001 black hair contains approximately 99% eumelanin and 1% pheomelanin, brown and blond hair contain 95% eumelanin and 5% pheomelanin; and red hair contains 67% eumelanin and 33% pheomelanin (Borges 2001).

The molecular chemistry gets messed up in alopecia areata, so the pigment process can get messed up, too.

When hair regrows it can also grow back in a different texture and color from what it used to be, too.
