## Before you buy

- Use frequency is listed as 1–2 times a week. The manufacturer suggests following with conditioner after rinsing, so buyers seeking an everyday-only shampoo should consider that distinction.

## A good fit for

- People looking for an occasional clarifying shampoo for product or hard-water build-up.
- Buyers with oily or fine hair who want a wash positioned for cleansing and residue removal.
- Those seeking a sulfate-free, paraben-free formula listed for a range of hair types and colours.

## Less suited to

- People seeking a shampoo explicitly intended for daily use.
- Buyers who need a product specifically confirmed to relieve scalp irritation, as customer feedback is divided on that point.

## Customer feedback

Customer feedback highlights perceived cleansing effectiveness, a small amount going a long way, and reports of clean, soft, shiny hair that stays fresh longer between washes. Customers also like the fragrance, while opinions differ on value for money and whether it helps with scalp irritation. For occasional clarifying use, reports of a concentrated formula may matter for how long the bottle lasts, but feedback does not establish a guaranteed result or suit every scalp.
- Positive themes: Customers report effective cleansing and say a small amount can go a long way.
- Positive themes: Customers mention clean, soft, shiny hair and a pleasant fragrance.
- Negative themes: Some customers feel the shampoo does not justify its price.
- Mixed feedback: Customers disagree on whether it helps with scalp irritation.
- Mixed feedback: Opinions differ on value for money.
