Hi doctor. I'm 23 years female. I had Loreal extensor straightening on dec 8 this month. So my hair stylist told to use loreal extensor shampoo, mask amd serum only. So I started using them. Now I'm getting so much itching in my scalp and noticed dandruff too. I never had dandruff till now but now I noticed dandruff in my hairs and even Itching. Is this because of shampoo or Straightening (this is my 2nd time) or weather change? I live in Hyderabad. I'm so tended.
