Reviews Summary
Customers say this hair treatment adds noticeable volume to fine and thin hair. Many reviews highlight its lightweight feel and ability to create fullness without leaving residue. While most users see immediate volumizing effects, some note results vary when used on wet versus dry hair. Reviews mention the product works well for styling without weighing hair down. Some users experience texture changes, with a few noting their hair feels dry or stiff. Most appreciate that it integrates easily with other styling products, though results can vary based on application method and hair type.

    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.
