From my childhood I have had the desire to grow hair as long as possible. But after growing to a certain length my hair refused to grow further. I read a lot of articles and advertisements and that is how met Dr. Shahid at his clinic. He prescribed vitamins, minerals like biotin, silica, beta-carotene, inositol and vitd3 supplements. Also prescribed some essential oil mixture for application on my hair. The rate of hair growth has actually speeded up. He said like how we need extra proteins for body building. So like that if you need extra growth, you need to take specific diet and add some nutrients.
