What is the purpose of Acid Balanced Shampoo?

• A. Formulated to phase the hair and skin used for all hair types. Same pH as hair.
• B. Coats the cuticle with wax to protect against residue.
• C. Provides temporary color to the hair.
• D. Removes oil from the scalp and leaves a residue.

Answer: (A)

Balancing the pH of hair and scalp is the key idea here. An acid balanced shampoo is formulated to have a mildly acidic pH, close to the hair’s natural level (around 4.5–5.5). When the pH matches, the cuticle scales lie flatter, so the hair feels smoother, looks shinier, and is less prone to frizz and damage. This pH helps color-treated hair retain pigment better and is gentle enough for most hair types, which is why this type of shampoo is commonly used for all hair types.

It isn’t about coating the hair with wax or forming a protective layer, nor is it about adding temporary color. It also isn’t meant to strip the scalp of oil and leave a residue; it cleans while maintaining the natural balance of the hair and scalp, rinsing clean without a heavy film.
