“I have naturally dark brown long wavy hair that I get foiled blonde every 4 weeks and straighten every day. Before using olaplex it was dry and split due to letting an apprentice colour it and I was considering cutting it all off to get it back to health. Now after using this for 6 months it’s the healthiest it’s ever been and it’s waist length! Would give more stars if I could! Love this stuff.....it’s a lifesaver”
