7. Can threading be performed on a client who is actively using isotretinoin (Accutane)? → No, isotretinoin thins and sensitizes skin making it prone to injury
8. Which laser type is considered safest for darker Fitzpatrick skin types (IV–VI) for facial hair removal? → Nd:YAG (1064 nm)
9. What product is most appropriate to apply immediately after waxing to calm redness? → Antiseptic spray or aloe vera gel

11. What is the primary purpose of a patch test before applying a new depilatory product? → To test for allergic reactions or skin sensitivity before full application
12. In what direction should facial hair be shaved to reduce the risk of ingrown hairs? → With the grain (in the direction of hair growth)
13. Threading removes hair at approximately which level? → At or near the follicle root
14. What is the correct technique for applying soft wax on the upper lip? → Apply a thin layer in the direction of hair growth

16. What are the three modalities used in electrolysis? → Galvanic, thermolysis, and blend
17. What is the primary advantage of hard wax over soft wax for facial hair removal? → It adheres to hair rather than skin, reducing irritation
