"Olaplex No. 3 Hair Perfector is not a conditioner, it’s an at-home treatment that contains the same active ingredient found in all professional Olaplex products. Created by two of the top PhD's in chemistry and materials science, Olaplex products feature first-of-their-kind, patented, bond-building technology, which relinks the broken disulfide bonds caused by chemical, thermal, and mechanical damage to the hair. This formula is made to work with every hair type, providing real, structural repair that works from within." Sephora
Olaplex is great for anyone with heat damaged or colour treated hair. Actually anyone can use this product; you don't necessarily have to have colour treated hair. I can swear by this product. It does absolute wonders. I'm so happy that Sephora carries this product, even though I wish the bottle was bigger and the price was lower (currently it sells for CAD $38.00). I've read some reviews where people leave the treatment overnight. I keep it on for a few hours (I don't know if i have enough patience to sleep with it in my hair) and I see a drastic difference in my hair. It is so much softer and much stronger. I’m not spending half an hour detangling the ends and my ends are much smoother. I have dyed hair so this is an absolute blessing!
Tip: the longer you leave it on your hair, the smoother your hair will feel. So I would recommend keeping it on for longer than 10 minutes as per the instructions. Try to keep it on as long as you can.
Go buy this product! Your hair will thank you for it!
