## Before you buy

- The listing calls the product paraben-, phthalate- and sulfate-free in its title, while the structured material-free detail specifies only paraben and sulphate free. The active-ingredient field says “carbon”, which does not match the listed biotin, hydrolysed keratin and chia seed oil claims. Check the selected pack’s ingredient information if these details matter.

## A good fit for

- People with fine hair looking for a refill-size shampoo marketed for volume and bounce.
- Buyers seeking a liquid shampoo with a fresh scent and listed anti-frizz and strengthening benefits.

## Customer feedback

Customer feedback highlights effectiveness for fine or straight hair, fragrance, softness and a lightweight feel. Some feedback describes hair looking fuller after blow-drying, while another report says it thickens without making hair coarse. This aligns with the product’s stated aim of weightless volume, but results are personal and the listing’s ingredient details are inconsistent. The aggregate ratings are strongly favourable overall, though a smaller share is low-rated and the figures do not explain why.
- Positive themes: Feedback describes softness and a lightweight feel after use.
- Positive themes: Some customers report fuller-looking hair, including after blow-drying.
- Positive themes: The customer summary reports positive responses to the fragrance.
