Nº.4 Bond Maintenance® Shampoo
Daily sulphate-free shampoo with bond-building technology
Olaplex's everyday shampoo — sulphate-free, gentle, and infused with the brand's bond-building active. Cleanses without stripping while providing ongoing structural repair. A solid everyday shampoo for colour-treated or damaged curls who want their wash step to do double duty. Contains silicones, which will build up over time without periodic clarifying — factor that in if you're using it regularly.
