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...

Amazing!
Hair Type Straight Hair
Received as part of an educational program. This product truly made such a difference within my hair with only one use. I've now used it three different times during my wash routine and it has made me feel like I have a whole new head of hair. I really do think that this product is not only worth the money but that it is something everyone with damaged terror needs to implement into their routine. I will be continuing to use this as needed and I think that moving forward this is going to be a product that is always going to be in my routine.
Soft hair!
Hair Type Wavy Hair
This product is very unique. You need to apply before shampooing. I had to use alot of product and applied roots to ends. After leaving in hair for 3 minutes, rinse and shampoo. I think my hair instantly felt soft while in the shower. I do like that it is a product you use before shampooing, that way it can soak in your hair and then you can clean. It smells so good and love how easy this is to use. I plan to use at least once a week to give my hair a boost of hydration. It made my hair so soft and smooth.
I'm obsessed!

I've been using the Olaplex No. 3 plus for a bit now and I really love it! The smell is really nice without being overpowering, I look forward to using it every week. What stands out the most is how soft my hair feels after. It doesn't feel coated or heavy, just smooth and healthier. I've noticed my ends look less dry and my hair is easier to manage overall. It's not an instant miracle, but with consistent use it really makes a difference!

This product is aaaaaaamazing !

Amazing repair product
Hair Type Wavy Hair
I am loving this new Olaplex number 3 plus hair treatment. It being a pre-shampoo product that only needs to be left on for three minutes is super convenient to use at home, on the go, or anywhere. I only need a small dollop for my hair so this bottle will last me a long time. Most importantly, it leaves my hair softer and smoother. I had the most dry, brittle ends prior to using this product and I have noticed a bit of a difference in my ends since I started using this product.

- Q
I cannot use many shampoos or anything in my hair that contains "sodium chloride" because it would wash out the Brazilian Keratin treatments that I get done to my hair. It does not say anywhere if this is safe for "chemically treated" hair? Would it wash out the Keratin treatment if I use Olaplex New No.3 PLUS?
- Asked by Deedah317
- Official Answer By Olaplex - Brand EngageNº.3PLUS is color-safe and suitable for chemically treated hair, and sodium chloride is not listed in the current ingredient list. Since Brazilian Keratin treatments can have specific aftercare requirements, we recommend confirming compatibility with your stylist or treatment manufacturer to help preserve your results.Was this answer helpful to you
