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.
