I am a 24 year old female, losing hair since 6 years. My scalp is oily and has sebum-blood filled pimples (5-20 in number) since 6 years. Dandruff is not much but it comes out thick. I have tried many homemade oil and shampoo. Sulphate and paraben free shampoo reduced the occurrence of pimples on scalp but made my hair rough. My hair is naturally soft, silky and straight-wavy. I do not apply any oil, spray or serum or heat and never had any treatment. Kindly suggest something as I have lost more than half the volume.
