Yes it's a thing... we're looking at you, teenage boys. Bacteria, oil and dead skin cells are often the main culprits behind that smell. As you know, the skin on your scalp is similar to the skin on your body (aka it's all skin) and skin produces sweat and has oil glands, so any buildup of sebum and sweat creates a breeding ground for bacteria - this can affect anyone but is a bit more obvious during puberty when the sebaceous glands are producing excess oil on the scalp. Use a scalp balancing shampoo and conditioner and be sure to massage into the scalp to remove build-up! We recommend the Normal Persons range by Evo for a deep cleanse and it's fresh peppermint scent.
