I've seen sites and pictures online that say castor oil cures baldness, complete with photos.
While there are some commercial products available that claim to stop and reverse hair loss, using home remedies work too. Castor oil for hair loss is one such home remedy.
Castor oil is replete with omega-9 essential fatty acids, which help to nourish hair and prevent the scalp from itching. In addition, the oil has ricinoliec acid, which is a fungicide. This prevents scalp infections, which can cause hair loss. The oil also works as a humectant and attracts moisture from the body to the scalp and skin. So, the hair stays soft and lustrous.
