This document discusses contraindications for waxing treatments and how estheticians should handle clients that may have medical conditions. If a client has severe skin conditions, skin diseases, diabetes, or severe varicose veins, the esthetician must recommend they seek medical advice before treatment and obtain a doctor's note. Diabetic clients have reduced healing and waxing can cause trauma, so a doctor's referral is required. Varicose veins may be damaged by waxing, so a note is also needed. Certain conditions like sunburn, cuts, or hairy moles will restrict how the waxing is done or parts that can be waxed.
