Helps protect against damaging free radicals and accelerated scalp aging caused by stressors like sun, poor water quality, irritants, chemical treatments, hair products, stress, lack of sleep, and an imbalanced diet.

Why does the scalp age faster than the rest of the skin?

The skin on the scalp has a naturally lower barrier function and slower cell turnover than the skin on the face and body. This means it is more susceptible to accelerated aging from factors such as sun, poor water quality, irritants, chemical treatments, hair products, stress, lack of sleep, and an imbalanced diet. A

study

showed that the skin on the scalp actually ages six times faster than the skin on the face.
