Reviews Summary
Customers say this volumizing treatment adds noticeable body to fine, flat hair. Many reviews mention the lightweight formula doesn't leave residue or greasiness. While most users with fine hair report improved volume and texture, some note subtle or minimal results. The product works best when applied to wet hair before styling, with many appreciating its natural-feeling finish. Some users find it particularly effective when blow-drying, though a few mention it can make hair feel dry or frizzy. Reviews frequently highlight its suitability for daily use and compatibility with other styling products.

    My hair has never been softer

    My hair is really long, fine, and color damaged. Nothing else has ever made my hair the way this product does. It's never been softer in my life, even when it was healthy. It's a gorgeous, lightweight product and it won't weigh your hair diwn at all.

    Excellent!

    Thus was my first Inkey product and it did not disappoint. I have fine hair and decided to try this and absolutely love it. Just enough volume and my hair is very bouncy and healthy looking :)
