(dandruff happens when your scalp is dry) SOOO here are some of them!! - olive oil! -it sounds gross, but when put near your roots, it moisturizes like crazy! it does the same wonders for your skin :) - mayonnaise -just put it all over your hair, and leave it in for around ten minutes. it's like an extreme moisture deep conditioning treatment! - Try stay hydrated and drink lots of water, to stop your scalp being dry. If nothing seems to work you may be best off consulting a doctor, they might prescribe something or check that there's no underlying medical issues.
