T1Broken, over-processed hair
Olaplex No.3 Bond Building Hair Perfector
Olaplex · 3.3 fl oz

The problem
Color, bleach, or heat has made hair stretchy, snap-prone, and dull — conditioner coats it, but the strands still feel weak.
Why it made the verdict
No.3 is a pre-shampoo bond builder, not a mask you rinse for shine. It made the list because it is the at-home step that actually belongs before you wash, not instead of washing.
Our verdict
Use it on damp, unwashed hair, then shampoo. If your hair has been chemically processed, this is the weekly repair vote — not a daily styler.
