Exfoliate, detoxify, hydrate, and treat a flaky scalp with John Masters Organics Scalp Exfoliating Scrub with Sugar Cane & Tea Tree Oil. This scalp scrub contains four natural exfoliants - organic sugar cane, bamboo, pumpkin enzyme, and AHA botanical fruit extracts. These natural exfoliants work together to help remove flakes, build-up, and excess sebum. Organic tea tree oil and wild thyme detoxify and help treat for a healthy, flake-free scalp. Scalp health is so important to maintaining healthy hair. Pollution, styling products and the use of chemicals that are clogging and irritating can wreak havoc on your scalp, which can lead to hair loss, flakes and unhealthy hair.
