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...

I will never purchase this product again
Hair Type Wavy Hair
I have used Olaplex for many years and never had any issues. Olaplex No.3 plus burned my scalp and skin. I do not recommend buying. The formula is different and does not work the same. Get K18 leave-in molecular repair hair mask instead.
A MUST in my hair routine
Hair Type Straight Hair
I have seen such a difference in my hair when I use this. Everyone complements me on my shiny hair. It is so much easier to brush and dries faster now too. This is as essential as shampoo and conditioner for me! Worth every $ spent for how well it works.

Hair Type Straight Hair
Hate that it is now owned by private equity, but aside from that, the formula change felt basic and didn't make a noticeable difference compared to the OG formula. I won't repurchase for the cost per use when it doesn't leave my hair feeling soft, I'll need to do more research, but most likely, as with all private equity, they reduce the quality of the formulation.
Made a difference
Hair Type Wavy Hair
My hair is dry especially at the ends and texture had changed due to low hormones in menopause. I had gotten highlights to blend emerging gray but it really dried out my hair and no mask or conditioning treatment was helping it. I used the Olaplex 3Plus leaving on about 5 mins. I rinsed out the Olaplex 3Plus and then I used a gentle co-wash and then conditioner(these were not Olaplex for cost reasons). Lastly after a gentle towel dry I used Olaplex 7 Bonding Oil and let it mostly air dry. I finished with a curler dryer on low setting. I was very pleased my hair tangled less and didn't feel like an old dried up broom. The most damaged ends were manageable but ultimately need to be cut. There was no heaviness or greasiness. I do recommend.
Hair game changer!!
Hair Type Straight Hair
I have been dying to try this product line for a long time. I have come across multiple people that have suggested the OLAPLEX brand to me in the past so when I got the opportunity to try it as part of an educational program, I was all for it. I have been struggling with heat damaged hair for a while now despite trying a handful of products that claim they fix damaged hair. I was shocked at how OLAPLEX 3 PLUS fixed my damaged hair after only using it one time. I am very impressed with this product and will continue to tell people about how well it reveres damaged hair.
