A barber is performing a consultation for a client who frequently swims in chlorinated water and notices their light-blonde hair has developed a greenish tint. What is the most likely cause of this discoloration?
- AAlkaline pH of the chlorinated water opening the cuticle.
- BOxidation of natural hair pigments by chlorine.
- CMinerals, specifically copper, present in the swimming pool water.
- DReaction of hair dye with chlorine in the water.
Show answer & explanationAnswer & explanation
Correct answer: C. Minerals, specifically copper, present in the swimming pool water.
The greenish tint in blonde hair after swimming in chlorinated water is commonly caused by copper, a mineral found in pool water, which binds to the hair protein and oxidizes, creating the green hue.
Why the other options are wrong
- A. While chlorine can affect pH and cuticle, this does not directly cause the green tint; it allows minerals to penetrate more easily.
- B. While chlorine can affect hair, the green tint is primarily due to mineral deposits, not direct oxidation of natural pigments.
- D. This can happen, but the green tint is more specifically linked to metallic buildup rather than a general reaction with dye.
