Acne and Dandruff
Dandruff can sometimes accompany acne, especially in adolescents. The causes are similar. For dandruff sufferers, the natural process of scalp-cell renewal is accelerated when fighting off P. ovale, a normal fungus found on every human head. This causes dead cells to slough more quickly, creating the symptoms we know as dandruff — flaking, scaling and itching of the scalp. In some cases, dandruff involves tiny pimples on the scalp. Climate, heredity, diet, hormones and stress can also impact dandruff. Most cases can be managed with non-prescription shampoos containing zinc, coal tar or salicylic acid. Stronger shampoos can be prescribed by your doctor if the problem continues. Dandruff isn't caused by over washing of the hair, so it's okay to shampoo every day. In contrast, scratching or picking the scalp can worsen the condition.
