Quoting Melissa Amazeen:" my hair suddenly got extremely oily an gross on the top of my heAd, i had this with my last pregnancy ... [snip!] ... i can do to clear it up? i also have to use dandruff shampoo because my dry scalp is out of this world...someone help please"
Also, apple cider vinegar is great for dandruff. I have seborrhoeic dermatitis in my eyebrows pretty bad, and just a swipe of that on each eyebrow ONCE, will get rid of it for months at a time. I'm interested to try it for the greasy hair because I too have gotten this issue. I thought it was my shampoo. I didn't have this problem when I used Pantene or Garnier Fructis.
