Alopecia is a condition that can cause hair loss, but fortunately, there are several steps that can be taken to help protect against this. First, it is important to use a gentle, non-irritating shampoo on the scalp. Look for shampoos that contain natural ingredients, like aloe vera, tea tree, or jojoba oil, which can help to soothe the scalp and nourish the hair. Additionally, be sure to massage the shampoo into the scalp using your fingertips. This can help to stimulate the scalp and promote circulation, which can help to promote hair growth. Lastly, be sure to rinse the shampoo out of the hair completely, as residue can clog the follicles and inhibit hair growth.
