No. 5 Leave-In Moisturize & Mend Leave-In Conditioner — Reddit Reviews
by Olaplex
Updated November 6, 2026
Serum-textured, silicone-free leave-in glides through curls; expensive for the bottle.
What the community says
A serum-textured leave-in conditioner that slips through wet curls and helps dry ends feel manageable. Curly and medium-texture users get easy slip without silicones, while fine hair needs a half pump and the luxury pricing is the main catch.
