Practice questionReviewedSkin Care and Services › Hair Removal, Lash, and Brow★★★★☆

Question 1. Which method removes hair from the root?

  1. ① Waxing
  2. ② Shaving
  3. ③ Depilatory cream
  4. ④ Trimming
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① Waxing

Key point: Waxing removes from the root

Waxing pulls out the hair root.

Wrong choices

  • Shaving: Shaving cuts hair at the skin surface, not at the root.
  • Depilatory cream: Depilatory dissolves at the surface.
  • Trimming: Trimming only shortens the hair above the skin.

  1. ① Waxing
  2. ② Tweezing
  3. ③ A chemical depilatory
  4. ④ Threading
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ A chemical depilatory

Key point: Depilatory dissolves hair

It breaks down keratin at the surface.

Wrong choices

  • Waxing: Waxing pulls the hair out from the root; it does not dissolve it.
  • Tweezing: Tweezing pulls the hair out from the root; it does not dissolve it.
  • Threading: Threading pulls the hair out from the root; it does not dissolve it.

Question 3. In which direction is wax applied and removed?

  1. ① Applied against growth and removed with it
  2. ② Applied and removed with growth
  3. ③ Applied and removed against growth
  4. ④ Applied with hair growth and removed against it
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ Applied with hair growth and removed against it

Key point: With growth on, against growth off

This pulls hair out cleanly.

Wrong choices

  • Applied against growth and removed with it: Applying against growth and removing with it would break hairs off instead of pulling them out well.
  • Applied and removed with growth: Removing the strip with growth tends to break the hair instead of pulling it from the root.
  • Applied and removed against growth: Applying wax against growth can push hair down and lead to breakage and irritation.

Question 4. Why should you check wax temperature before applying?

  1. ① To make it stick better
  2. ② To remove it faster
  3. ③ To avoid burning the client
  4. ④ To sanitize it
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ To avoid burning the client

Key point: Test wax temperature

Hot wax can burn.

Wrong choices

  • To make it stick better: Temperature is checked for safety, not to change how well the wax sticks.
  • To remove it faster: Temperature is checked for safety, not to speed up removal.
  • To sanitize it: Warm wax does not sanitize anything, and it is not checked for that reason.

Question 5. Why should you never double-dip a spatula into the wax pot?

  1. ① It spreads germs
  2. ② It wastes wax only
  3. ③ It makes wax thinner
  4. ④ It burns the spatula
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① It spreads germs

Key point: No double dipping

Double dipping contaminates.

Wrong choices

  • It wastes wax only: Waste is a small issue; the main danger is spreading germs between the client and the pot.
  • It makes wax thinner: Double dipping does not change how thick the wax is.
  • It burns the spatula: A spatula does not burn from the wax.

Question 6. Which client should NOT be waxed?

  1. ① One with normal skin
  2. ② One with dry skin
  3. ③ One taking isotretinoin
  4. ④ One who last waxed six weeks ago
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ One taking isotretinoin

Key point: Isotretinoin: no waxing

The skin is fragile.

Wrong choices

  • One with normal skin: Healthy normal skin is not a reason to refuse waxing.
  • One with dry skin: Dry skin alone is not a contraindication for waxing.
  • One who last waxed six weeks ago: A client who waxed six weeks ago is a good candidate because the hair has regrown.

  1. ① To check skin type
  2. ② To check for allergic reaction
  3. ③ To match color
  4. ④ To check hair growth speed
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② To check for allergic reaction

Key point: Patch test for allergy

Do it ahead of time.

Wrong choices

  • To match color: A patch test is not used to choose a color.
  • To check hair growth speed: A patch test says nothing about hair growth speed.

  1. ① Wearing gloves
  2. ② Applying wax over broken skin
  3. ③ Testing wax temperature
  4. ④ Holding skin taut
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② Applying wax over broken skin

Key point: Never wax broken skin

It causes injury and infection.

Wrong choices

  • Wearing gloves: Wearing gloves is a safe practice, so it is not the answer.
  • Testing wax temperature: Testing the temperature is a safe practice, so it is not the answer.
  • Holding skin taut: Holding the skin taut is a safe practice, so it is not the answer.

  3. ③ Tweezing
  4. ④ Sugaring
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② Electrolysis

Key point: Electrolysis is permanent

It treats each follicle.

  • Tweezing: Tweezing is temporary because the follicle is not destroyed.
  • Sugaring: Sugaring is temporary because the follicle is not destroyed.

  1. ① Avoid hot tubs, sun, and scrubs
  2. ② Exfoliate heavily
  3. ③ Use a tanning bed
  4. ④ Use perfumed lotion
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ① Avoid hot tubs, sun, and scrubs

Key point: Aftercare

Skin is irritated.

Wrong choices

  • Exfoliate heavily: Scrubbing freshly waxed skin irritates it.
  • Use a tanning bed: Sun and tanning beds can burn and darken freshly waxed skin.
  • Use perfumed lotion: Perfumed products can irritate freshly waxed skin.
