I have thin hair and become very oily after 1 day of wash even if I don't apply any oil. My scalp has dandruff also and I washed my hair every second day to get rid of oil and dirt without apply oil for almost 6 months but after that I suffered from a tragic hair fall which is continued till now. Please tell me the causes and treatment of hair fall. Can my hair regrow again nf yes then how much time will they take. I am very worried about it. I have also started apply topisal lotion. Will it be effective or not?
