Worth the hype!
Trying Olaplex No. 3 Hair Perfector for the first time felt a little overdue. I had heard about it for years, friends raving, stylists recommending it, social media constantly calling it a "holy grail." At the same time, I've tried enough hyped-up hair products to know that not everything lives up t...

Subtle but Strong: Olaplex No.3 Plus Strengthened My Hair
I've been a fan of Olaplex products for a while and I've loved almost everything I've tried, but I have to be honest this one didn't really impress me at first. I made sure my hair was really dirty before trying it so in my before photo you can clearly see it was greasy, flat, and had no life. I app...

It Works!
Hair Type Wavy Hair
I love Olaplex much more after trying this product. My ends are very damaged with split ends and uneven pieces. This product made my curls more defined and softer. I would say any hair type this would be helpful. It's very hydrating and easy to use. Amazing job Olaplex. Received as a part of an educational promotion
My hair loves it!!!
Hair Type Wavy Hair
I have been using the Olaplex No.3 Plus Complete Repair Treatment and I can see why it's such a popular hair treatment. It helps strengthen and repair damaged hair while leaving it feeling softer and smoother after each use. I like using it as a pre wash treatment because it makes my hair look healthier and less frizzy without weighing it down. It is great for anyone dealing with dryness, breakage, or heat damage.


Simple Treatment That Works
Hair Type Straight Hair
Before this, my hair felt dry and kind of rough, especially at the ends and it didn't look very smooth. I tested this out, and the difference I see is after using it about 3 times. My hair feels softer, smoother, and just looks healthier. It's easier to brush and doesn't feel as dry anymore. I apply it on damp hair, leave it on for a bit, then rinse it out and follow with my shampoo and conditioner. After that, my hair feels really nice and smooth. It doesn't weigh my hair down, which I like. I'm going to keep using it 2-3 times a week. I feel like it actually helps over time.


Transforms dry damaged hair after one week
Hair Type Very Curly Hair
I did received this as a part of an educational promotion. I have been using this treatment for the past week and I can already feel a difference in my hair. My ends feel softer, my hair looks smoother, and it feels stronger after washing. I used it before shampooing as directed and noticed less dryness and frizz. My hair feels healthier and more manageable. A little goes a long way, so the bottle should last. I would definitely continue using this treatment and recommend it for damaged or overprocessed hair.

So recommend for anyone who wants shiny, healthy hair!
Hair Type Wavy Hair
One of my biggest hair problems is hair breakage. My hair type is considered thick but after getting multiple perm treatments, it's definitely weakened my hair cuticles. Recently, I started using Olaplex's Complete Repair Treatment and my hair has been feeling stronger and healthier. Before shampooing, I leave the Olaplex treatment in for 3 min. I also love the way it smells - it's like a combination of citrusy/floral with clean detergent. Would definitely recommend this product for anyone that wants to improve their hair quality because my hair has been shiny since using it! *received this as a part of an educational promotion
