Behind No 0 lies Olaplex’s bond rebuilding science. In tests, when used with No 3 and No 4 as a system, it delivered notably more repair and hair that felt stronger after a single use. The formula uses patented technology that rebuilds disulfide bonds without adding protein, acting as a primer to boost the depth of subsequent repair. Developed in Olaplex labs, this approach positions it among the best hair products for hair growth; it also complements alternatives like the k18 hair mask in a holistic haircare routine.
