Hi. I have oily scalp and fine hair. I have been using sunsilk black shine shampoo for years without conditionar. I always massage hot oil night before on my scalp and hair. From past one year i am facing issue of hair fall and dandruff. I tried many different shampoos but nothing is working out for me. Please provide your guidance. Also note from past one year i have relocated so weather and water is totally different from what i had for years
