Detailed answer

Using sunscreen on your scalp is important to protect it from harmful sun rays and reduce the risk of sunburn and skin damage. You can use a sunscreen specifically designed for the scalp or regular sunscreen with a spray or lotion formula. Apply it generously to your exposed scalp, making sure to cover all areas. Reapply sunscreen every two hours or more frequently if you sweat heavily or go swimming. Additionally, wearing a hat or using other protective measures like seeking shade can provide added protection for your scalp from the sun's rays.
