Can you use the No.0 alone?
This intensive repair booster is designed to work alongside the use of No.3. Whilst No.3 can be used on it's own, it's recommended you don't use No.0 alone.
It will give some repair on it's own, however it's best paired with No.3.
OLAPLEX works best with wet hair, No.0 dries very quickly so it's best to keep the hair wet (which is what No.3 does) so that it can continue to deliver intense hydration.
Can No.3 be put on immediately after using No.0 to save my time?
No - OLAPLEX recommends that No.0 needs to fully absorb for 10 minutes before you add No.3.
Can No.0 be used on all hair types?
Yes - No.0 can be used on all hair types and textures with benefits to all! Those with damaged hair will see the visable results quicker than those with healthier hair. Even those with healthier hair will see results in the longer run, as the formula is still working within the hair structure.
How long can I leave No.0 in my hair?
No.0 and No.3 can be left in for around 30-45 minutes or until the hair dries. Rinse, shampoo and condition for best results.
