question 2 of 25
identify a guideline that you should follow while styling hair using a thermal iron.
select the correct response:
use metal combs rather than plastic combs when styling hair.
test the irons temperature by clamping it around a white cotton towel or tissue for five seconds before placing it on the hair.
use only cellulose acetate combs for thermal curling services as they are nonflammable.
never place a comb between the scalp and the thermal iron when waving or curling hair at the base of the head.

Explanation:

Analyze thermal safety guidelines

Using the Thermal Iron Safety knowledge point

• Plastic or cellulose acetate combs can melt or burn when exposed to high heat.
• A nonflammable hard rubber comb should be placed between the scalp and the iron to prevent burns.
• Testing the iron's temperature on a white cotton towel or tissue paper for five seconds is the standard safety procedure to ensure it is not too hot.

Evaluate the given options

Using the Thermal Iron Safety knowledge point

• Option 1: Incorrect. Hard rubber combs are preferred over metal combs because metal conducts heat and can burn the scalp.
• Option 2: Correct. Clamping the iron on a white towel or tissue for five seconds is the standard method to test for overheating.
• Option 3: Incorrect. Cellulose acetate combs are highly flammable and must never be used with thermal tools.
• Option 4: Incorrect. A comb must always be placed between the scalp and the iron to protect the client from burns.

Answer:

• Use metal combs rather than plastic combs when styling hair.
• Test the iron's temperature by clamping it around a white cotton towel or tissue for five seconds before placing it on the hair. (Correct answer)
• Use only cellulose acetate combs for thermal curling services as they are nonflammable.
• Never place a comb between the scalp and the thermal iron when waving or curling hair at the base of the head.
