Choonkar's Onion hair oil ! Onion hair oil is a proven remedy since the times of Ayurveda. Obviously! We have always loved our grand mother's hair and wish to have hair like them. It's all because of homemade recipes of our Nani-maa which we ignored. Who doesn't like to have champi but in our busy schedules we don't get enough time. Onion hair oil effectively works in promoting hair growth and due to the presence of antioxidants, it nourishes your scalp and improves the blood circulation, thus ensuring thicker and stronger hair growth. Applying onion hair oil in the crown area of the scalp ensures regrowth of dark and thicker hair.
