I have experienced my hair really improving with getting rid of my tape worms, (and others). My hair got brittle, and dry, and thin, but I thought it was because of menopause, and generally getting older. Both my skin and hair are much more supple, my hair doesn't break off like it did when I brush it, and my skin is softer.
So yes, I had problems with my hair that have improved. I don't think it's conincidence.
