If you suffer from dry, damaged, chemically-processed hair, then this is the hair treatment that you absolutely need! I have had multiple treatments done in my hair (e.g. L’Oreal Powerdose), but the Olaplex treatment is my favourite professional treatment. This treatment will strengthen your hair by repairing the bonds that can be damaged due to colouring in between colouring sessions. Your hair stylist can also mix the treatment into your colour. I went from having almost-black hair to light blonde and this treatment has helped make that transition successful with minimal to no damage to my hair. My hair stylist always compliments me on the absence of split ends and how healthy my hair is. I have my hair regularly coloured blonde with 30 volume, but after this treatment, my hair is very soft, much smoother and noticeably less tangled. It even feels great after the next couple of washes. Be sure to ask your professional hair stylist for Olaplex No. 3 the next time you see them!
