The pump in N°.8 is one of the things that make it truly unique. It is made for precision dosing and also prevents the product from weakening by not allowing water to infiltrate the formula, which often happens with other masks. 

As you may know, relaxers usually tend to be the strongest chemical one can use on their hair, so the risk of damage and moisture loss is something one has to be aware of and address. N°.8 works amazingly in addressing moisture loss and also helps heal the hair as well.

No OLAPLEX N°.8 should be used by itself after shampooing (preferably with N°.4)

Heat does not affect how well OLAPLEX works, so that would be a matter of preference.

OLAPLEX N°.8 goes directly into the hair shaft; unlike most traditional masks that sit on the surface, OLAPLEX works internally, giving your hair moisture from the inside out. OLAPLEX N°.8 also gives your hair immense shine and body as well so having a moisture mask that doesn’t weigh the hair down that in itself is groundbreaking!

We recommend shampooing first with N°.4 then applying N°.8 to damp hair (mid-lengths to ends). Most only require 2-4 pumps. Remember that N°.8 absorbs into the hair, so you won’t see it sitting on top of the hair strand, so less is more. Finger or comb through, allow it to sit for a minimum of 10 mins then rinse. N°.8 is designed to replace your daily conditioner on days when you feel you need more moisture.
