A few months ago, I was looking at old photos with friends, and I was floored to see how full and thick my hair used to be. I know hair changes as we get older – and it's not like I'm balding or anything – but seeing the side-by-side difference was eye-opening.

Since then, I've spent hundreds of dollars (and maybe just as many hours researching and staring in the mirror) trying to get some of that fullness back. Minoxidil from Hers caused itchiness and irritation; Nutrafol and Divi yielded underwhelming results after weeks and weeks of use; and Vegamour's GRO Serum showed so few early signals that I ended up returning it within the 30-day return window.

After all that trial and error, I've finally found a solution that’s starting to work. Here’s why I’m loving RE:YOU's Dual-Path Hair Revival Serum.
