Itching and/or rashes may be linked to several unrelated causes, so it is important to obtain a tanning history on each customer. Some people are naturally photosensitive upon exposure to ultraviolet light. Others are susceptible to heat rashes, a cause totally unrelated to the UV exposure. Certain chemicals or ingredients found in cosmetics, lotions, shampoo, and even disinfecting agents may cause itching as well. Rashes caused by these products generally occur in localized areas on which the products were applied. It is advised to tan with the skin as clean as possible and to only use products approved or suggested by your tanning consultant. If discontinued use of a suspected product does not inhibit the problem, a person should discontinue any exposure to UV light until the condition subsides or visit a physician.
