My Buying Guides on Garnier Fructis Root Amp
What I Looked for Before Buying
When I first considered Garnier Fructis Root Amp, I focused on whether it would give my hair noticeable lift at the roots without making it feel sticky or heavy. I also checked if it matched my hair type, since root-lifting products can work very differently on fine, flat, or oily hair.
