What effect does an acid have on the hair's cuticle?

Swells the cuticle
Closes the cuticle
Bleaches the hair
Has no effect

The correct answer is: Closes the cuticle

An acid can cause the hair's cuticle to close, which can help improve the overall health and appearance of the hair. Options A and C may seem like possible effects of an acid on the hair, but they are not the best answer because they do not describe a positive effect. A swollen cuticle can make hair appear dull and frizzy, while bleaching the hair can cause damage. Option D is also incorrect because acids do have an effect on the hair's cuticle.
