My hair were so thick and long but suddenly I had to face hair fall and my hair gone so thin and short. I used so many products but nothing did better to it. Then I used patanjali amala juice and it made my hair little thick but not so much. And the most big problem is that my hair are not growing long. For 3 years they are of same length. Which product should I use easily available in market. Which can make my hair really thick and long? please tell me the best product.
