🔒 100% Authentic Olaplex – sourced from authorised distributors, backed by our Money Back Guarantee.
A shampoo that doesn't strip hair of the bonds you've spent weeks rebuilding. No.4 keeps the surfactants mild enough that fine or flat hair doesn't weigh down, but tough enough to actually clean without leaving film.
1000ml bottle — the size that makes sense if you're using Olaplex treatments regularly. Works on its own, but the system works better together: cleanse with this, then rebuild with No.3 before shampooing out. Two pumps per wash for most hair lengths.
