Hair fall is a common issue caused by stress, poor diet, pollution, and lack of proper care, but using the right hair growth oil can help strengthen roots and promote healthy hair. Oils like coconut oil, castor oil, argan oil, onion oil, and almond oil are rich in essential nutrients that nourish the scalp, reduce breakage, and improve hair texture. To get the best results, warm the oil slightly, massage it into the scalp to boost blood circulation, and leave it on for a few hours or overnight before washing.
