Reviews Summary
Customers say this hair treatment adds noticeable volume to fine, thin hair without leaving it heavy or weighed down. Many reviews mention the lightweight feel and natural-looking results. While most users with fine hair report improved fullness and bounce, some note the effects vary when combined with other styling products. Reviews highlight its effectiveness on wet hair, though experiences differ on dry application. Some users appreciate the product's subtle approach, while others expected more dramatic results. The texture works well for most, though a few mention it can feel sticky if overused.

    Fab!

    My hair is thinning a bit due to the perimenopause, so I thought I'd give this a go. I've been using it for about a month now; twice a week. I got my hair cut today, and my hairdresser remarked on how my hair has become fuller. This came apropos of nothing as I have never mentioned using any kind of product.

    I'm delighted with this and will continue to use it as it's so simple to apply and you can use your other styling products (if any) afterwards without any problems.
