That's a strange first post. I really do not care which shampoo I use..I am fully bald, but still shampoo my head everyday, sometime twice, but I just grab My Wife's shampoo usually.
Shampoo is a scam. Ditch it and opt for a periodic cleansing with baking soda and apple cider vinegar instead. You'll save money and after a while, your hair will never look better.
