Bad Dandruff (SD?)
FOR THOSE WHO'VE TRIED NATURAL REMEDIES (ACV), SHAMPOOS, ETC., ALL TO NO AVAIL:
Go to your local Health Food Store, or online, and order an all-natural Jojoba Shampoo. What cured me was using this shampoo + tea tree oil. You will have to find out which way of doing it will work best for you. I have a shaved head so I just shampoo in the shower, rinse, and apply tea tree oil with Distilled water, on a cotton pad, onto my head afterwards (without washing it out; having a shaved head makes that easy for me to do). You may have to start with the tea tree oil, leave it in for an hour (or longer) and then wash with the Jojoba shampoo. You may also want to get Jojoba Conditioner.
