California Cosmetology Written ExamHair RemovalMedium
A client mentions she takes a daily prescription anticoagulant (blood thinner) for a heart condition and requests a full-leg wax service. Why is this medication history a contraindication for waxing?
- AIt permanently stops hair regrowth in the treated area
- BIt causes the wax to melt at a lower temperature
- CIt increases the risk of excessive bruising, bleeding, and skin tearing during wax removal
- DIt triggers an allergic reaction to the wax resin
Show answer & explanationAnswer & explanation
Correct answer: C. It increases the risk of excessive bruising, bleeding, and skin tearing during wax removal
Blood thinners reduce the blood's ability to clot, making the skin more prone to bruising, bleeding, and even skin tearing when the wax strip pulls hair and adhered skin cells during removal. A cosmetologist should proceed cautiously or refer the client to a physician before waxing.
Why the other options are wrong
- A. Blood thinners do not affect hair follicle growth or regrowth.
- B. Blood thinners have no effect on wax's physical melting temperature.
- D. Allergic reactions relate to wax ingredients, not blood-thinning medication.
Anticoagulant (Blood Thinner) Contraindication
Clients on blood-thinning medications are at higher risk of bruising, bleeding, and skin tearing during waxing due to reduced clotting ability.
- Increases bruising/bleeding risk during hair removal
- Skin may tear more easily when wax strip is pulled
- Cosmetologist should proceed cautiously or refer to a physician
