Your scalp can become itchy and dry as a result of chemo and radiation. Many chemotherapy drugs also cause hair loss. Some of the products on this page help cleanse the scalp, keep your hair follicles clean, and moisturize the scalp, reducing the itch and dryness. The Thymuskin product line was developed for hair retention and thickening. It can be used before and during radiation and chemotherapy to prevent or reduce hair loss, and to stimulate new hair growth. Thymuskin also helps reduce balding and combats alopecia in healthy individuals.
