Revolution Haircare Plex 3 is a restoring and conditioning plex treatment to use before shampoo and conditioner. What is Plex? Revolution’s Plex triple molecular weight protein cascade system targets different layers of the hair fibre helping to repair and strengthen damage from within. The Plex range not only contains the triple weight molecular protein system, but each formulation has been expertly formulated to provide the best ingredients for the hair. The protein system is made from three different types of plant protein that have been selected to target different parts of the hair fibre. The power combination of Phytantriol and Provitamin B5 work to keep hair hydrated and healthy, whilst a blend of conditioning agents help to soften and smooth the hair. Use step 3, 4, 5 and 6 as a routine to give your hair the love it needs; restores, increases strength, conditions, enhances shine, reduces frizz.
