My Honest Review
After testing Olaplex No.3, it’s clear why it has cult status. Hair feels smoother, stronger, and looks visibly healthier after a few treatments. It won’t transform hair overnight, but with consistent use, breakage and frizz are dramatically reduced.
It’s especially amazing for bleached or chemically processed hair — if you’ve ever walked out of the salon with fried ends, this product is your best friend.
