Why should products always be tested on the skin before use?

• A. To check for allergic reactions or sensitivity.
• B. To ensure fragrance is pleasing.
• C. To verify color compatibility with makeup.
• D. To ensure they remove hair.

Answer: (B)

Testing products on the skin before use is about safety. Different people can have allergic reactions or sensitivities to ingredients in barber and cosmetic products, even if they’ve used similar items before. A small patch test helps reveal whether a product could cause redness, itching, swelling, or irritation before it’s applied more widely, reducing the risk of a full-blown reaction on a larger area. If a reaction occurs, it’s a signal to avoid that product or choose an alternative with gentler ingredients. The idea isn’t about fragrance being pleasing, color compatibility, or hair removal—that’s not the primary reason for skin testing.
