I have an oily scalp and got dandruff for more than 10 years. I went to a trichologist in 2010 and he prescribed me daily use of Head & Shoulders shampoo and Candid TV shampoo twice in a week. After using these two shampoos for months, the dandruff completely went off my scalp but I started noticing hair thinning in the crown area. Thereafter I changed to herbal shampoos like Biotique, but the hair thinning continues and even the itchiness is also there. Two years ago, I shifted my residence and use hard water to wash my hair. In The last two years, the hair thinning increased and scalp is visible in certain areas. I also have dandruff like flakes on my eyebrows, ears and moustache. Please suggest me a way to stop hair thinning and also should I continue using these shampoos on a daily basis.
