A staple product as part of my hairstyling routine

Not only lifts but thickens my hair strands while burnishing them. I found the only tools I needed with this product was a young brush and a blow dryer. I normally finish my bangs and ends with a hair straightener to smooth the ends. Wasn’t necessary, which I live!

Didn’t work for my fine hair. Zero resulting volume, any volume I had initially after a blow dry fell flat almost instantly. Plus denatured alcohol is the second ingredient which damages and horribly dries my hair out. Plus alcohol
