Has anyone tried ultraviolet rays against dandruff? I know they use it for psoriasis, and psoriasis is much more violent than common seborrheic dermatitis, so it should make sense.
Same. I noticed a flare up with my flaking wicked bad in winter and it hasn't ended. I beleive it's a lack of sun and the dry air. I try sitting near a window but it's just not working. People in Florida and California are soooo lucky.
