We checked with Dr. Irwin Goldstein, who helped write the study on oral contraceptives in the Journal of Sexual Medicine (January 2006). According to Goldstein, many hormone replacement therapies contain estradiol. Estradiol boosts levels of sex hormone binding globulin (SHBG). Then the SHBG attaches to women's testosterone and makes it less available.

I have a problem with a yeast condition (seborrhea) that covers my scalp. Should I avoid yeasty food like yogurt?
Yogurt does not contain yeast, and there is little data to suggest diet has an effect on seborrheic dermatitis (super dandruff). Some readers tell us that massaging old-fashioned (yellow) Listerine into their scalps helps this condition.
