Is my hair addicted to dandruff shampoos?

I have dandruff that responds well to over-the-counter shampoo. Ergo, I have been using the stuff almost exclusively for ten years. No brand in particular, sometimes zinc pyrithione (the blue stuff!), sometimes coal tar (the smelly brown stuff!). Anytime I switch to non-dandruff shampoo for like three to four days straight, I get my dandruff back. I worry that I might be addicted to dandruff shampoo. Should I worry?


What are some tips and tricks for lasting longer during sex?

1) What is the best way to learn how to prolong male orgasm when having intercourse? It seems that I might get thirty seconds of penetration before I blow my top. I'd like it if I could enjoy the situation and add to my partner's pleasure by helping her orgasm.

2) I just wrote asking about how I might prolong my orgasm so that my girlfriend might be able to reach hers. I've read through your archives extensively, so I've seen all the "orgasm is personal and shouldn't be concentrated on" so I've seen that and whatever. I just want one issue discussed: how to prolong MYSELF to please her. I'm looking for answers such as: exercises, workouts, diets, surgery (jk). Please help me please her.
