Apply to wet hair, focusing on the scalp and working through to ends. Lather fully and leave on for up to 5 minutes. Buildup of impurities from your water, hair products, and even your air can look like signs of damage. If left in your hair, they can lead to real damage like split ends, breakage, and frizz.

My hairdresser recommended I switch over to Olaplex's shampoo and conditioner after I said I was looking for a good sulphate-free shampoo. I'd already used Olaplex 3 and always get the in-salon treatments, so tried them out. Sure enough, they do the job, making my hair stronger and healthier over time. But I did find that, given they are sulfate-free formulations, that I got some build up after a few weeks. I added the clarifying shampoo in, using it about twice a month, and now have the perfect hair routine (I also use Olaplex 3, 9 and whatever number the mask is). Follow up with Nº.5 BOND MAINTENANCE CONDITIONER or Nº.8 BOND INTENSE MOISTURE MASK for extra moisture. With a Broad Spectrum Clarifying System and scientifically proven Bis-Aminopropyl Diglycol Dimaleate. Most clarifying shampoos strip the hair, leaving it feeling straw-like, rough, and dry. Nº.4C is formulated with patented OLAPLEX Bond Building Technology™ to maintain strong hair bonds as the clarifying system removes damaging impurities, leaving the hair touchable, soft, and never dry or straw-like.
