What to know before buying
Listing details to confirm
The volume, finish and heat-protection figures are listing claims rather than independently verified results. The stated routine calls for damp hair and blow-drying, although customer feedback also describes use with air-drying. The listing gives the quantity as both 6 Fluid Ounces and 177.0 millilitre, and dimensions include a separate weight that differs from the listed item weight. Check the selected listing if exact quantity or weight matters.
Who is it for?
A good fit for
- People seeking added volume and a fuller-looking finish as part of a damp-hair styling routine.
- Those who want a styling spray with a stated heat-protection claim for blow-drying.
Less suited to
- Buyers who need a fragrance-free product, as the listed scent is Cape Town.
- Anyone seeking a spray guaranteed not to feel greasy, since customer feedback on greasiness is mixed.

Customer feedback describes added thickness and volume, pleasant fragrance and a soft feel, with users reporting use alongside air-drying as well as blow-drying. Greasiness is a point of mixed experience, so the advertised non-sticky finish should not be treated as guaranteed. The overall rating pattern is mostly five-star but includes lower ratings too. For buyers using it before blow-drying, that feedback is relevant to the intended styling routine, while individual results and finish may vary.
Positive themes
- Feedback highlights perceived effectiveness, volume and a pleasant fragrance.
Mixed feedback
- Opinions on greasiness differ, with some describing a non-sticky feel.
