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...

Works great to repair and tame hair!
Hair Type Wavy Hair
This is the first time I've used a pre-shampoo repair treatment so I wasn't sure what to expect. I can honestly say that I'm a believer, and that I saw noticeable results even after just one use. I left the product on for the recommended 3 minutes, then shampooed and conditioned like usual. Typically after washing and blow drying, my hair feels frizzy and pretty dry. I noticed after using, my hair was smoother and just felt stronger. It was even better after the 2nd time I used the product. It also made my hair feel more tame and manageable for days after using and in between washing. I'm very happy with the results and will purchase in the future. I received as a part of an educational promotion.


Love it!
Hair Type Very Curly Hair
My go to when I'm going from a straight winter back to a curly spring and summer. This makes my curls look juicy and feel great.
Love it after second use
Hair Type Wavy Hair
I tried the Olaplex No.3 Hair Perfector and I have mixed but overall positive feelings about it. The first time I used it, I honestly didn't see a huge difference. My hair felt a little softer, but nothing that made me think wow. I gave it another shot a few days later, and that's when I started to notice the change. After the second use, my hair looked noticeably healthier and had a really nice shine to it. It felt smoother, less dry, and easier to manage, especially on my ends. It's not an instant miracle product for me, but with consistency it definitely works. I would say it's worth it if you're patient and willing to use it more than once to see results. Not a one time fix, but it does deliver over time.

Visible repair and softer hair after just a few uses
Hair Type Wavy Hair
I have wavy hair that tends to get dry on the ends, especially after heat styling. I started using Olaplex No.3 Plus as a pre shampoo treatment and it made a noticeable difference in how my hair feels and looks. I apply it to damp hair and leave it on before washing. After rinsing and styling, my hair feels noticeably softer, smoother, and much easier to manage. My ends look healthier and I see less frizz overall. What I like most is that it does not weigh my hair down. My hair still feels light and bouncy but stronger at the same time. With continued use I also noticed my hair looks shinier and feels more resilient. This treatment is great if your hair has been damaged from coloring, heat tools, or just needs extra repair. It fits easily into my routine and feels like a great weekly reset for my hair. I would definitely keep using it and recommend it to anyone looking to improve the strength and overall health of their hair.
Nice results with consistent use
Hair Type Straight Hair
I have been using this treatment for a couple of weeks now and I can see a difference, especially on my ends. My hair feels softer and looks less dry after I use it. I like that it only takes a few minutes. I apply it on wet hair before shampooing, leave it on for about 3 minutes, and then rinse. It fits easily into my routine and does not make my hair feel heavy. I also want to mention the scent — it is absolutely amazing, and what I love most is that it actually stays on my hair even after washing. It is not an instant fix, but with regular use my hair looks healthier and feels easier to manage. I received this product as part of an educational promotion.
