The science of NAD+

The science explained

Formulated with Olaplex patented bond-building technology, Nº 4P works at a molecular level to strengthen the hair while delivering precise, even toning. The highly concentrated purple pigments counteract brassiness without drying, leaving hair visibly brighter and smoother. The 1000ml size is ideal for salon use or for maintaining blonde results long term at home.
