The condition of your scalp is affected by numerous factors including stress, hormonal irregularities, diseases and diet. Just as your facial complexion is affected by changes within your body, the condition of your scalp can be another external measure of your overall health. Sudden changes occurring on the scalp could signal an imbalance in your body or indicate an underlying disease. Skin cancer can also occur on the scalp, particularly in areas not well covered by hair. It can destroy skin cells and tissues and, in some cases, spread (metastasize) to other parts of the body. Skin cancer may appear as a growth or mole, a change in a growth or mole, a sore that does not heal, or irritation of the skin. Get a friend or your partner to check your scalp regularly for suspicious lesions and make it a habit to wear a hat when you’re out under the sun. Maintaining and preserving the health of your scalp starts with keeping your hair clean, so routinely wash and condition. If dandruff is a concern, try medicated conditioners with an antifungal agent, such as pyrithione zinc, to effectively treat and manage the flaking.
