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...

Noticeable difference after just a few uses
Hair Type Wavy Hair
*Product was received as part of an educational promotion.* I honestly didn't expect a big change at first, but after adding this to my routine, I could tell my hair felt different right away. Usually, when I just shampoo and condition, my hair feels okay but nothing special. After using No.3, my hair felt softer and looked healthier, especially at the ends. I used a small amount on damp hair before washing and left it on for a few minutes. It didn't feel heavy or greasy, which I liked. After rinsing and styling, my hair felt smoother and less frizzy. Over time, I also noticed less breakage when brushing. The texture is lightweight and easy to spread, and the scent is mild and pleasant, not overpowering. It fits easily into my routine without taking too much extra time. Overall, I think this is a great product if your hair feels dry or damaged and you want something that actually helps without weighing it down. I would definitely keep using it.


Works from the first use
Hair Type Wavy Hair
I originally thought I would need to use Olaplex No. 3 more than once to see real results, but I was honestly surprised by how effective it was after just the first use. My hair is bleached and quite damaged, and I usually struggle with frizz and flyaways that don't go away—even after a blowout or using a flat iron. But after using Olaplex No. 3, my hair felt noticeably calmer, smoother, and more manageable right away. It gave my hair a soft, polished look that I haven't been able to achieve easily before. What I really like about this treatment is that it doesn't just sit on the surface—it actually works to repair the hair from within. Olaplex No. 3 is designed to rebuild broken bonds in the hair, which is especially helpful for chemically treated or heat-damaged hair like mine. After using it, my hair felt stronger, less brittle, and looked healthier overall. It's also easy to use: I apply it to damp hair, leave it on for at least 10–20 minutes (sometimes longer for better results), and then shampoo and condition as usual. A little goes a long way, and it doesn't weigh my hair down. Overall, I'm really impressed with how quickly it worked. If you have bleached or damaged hair and struggle with frizz, dryness, or lack of smoothness, this treatment is definitely worth trying


Shiny healthy hair
Hair Type Wavy Hair
I have fine, thin, long hair that tends to be dry but because my scalp is oily, I need to wash it every day. I am very careful with the products I use to avoid weighing my hair down or making it look limp and unwashed. However, frizz is also a major concern for me, and it can be difficult to find the right balance between not overusing conditioners or masks and still keeping my hair smooth and good-looking. I had used Olaplex products before but it was my first time trying Olaplex No. 3. Knowing it has an updated, more powerful formula made me even more excited to try it. I absolutely loved it from the very first use. My frizz was noticeably tamed and my hair looked fuller with more volume, and I saw a healthier shine overall. My strands and natural waves also looked much more defined which I was happy about the most. I will definitely keep using this product because of the amazing results I've seen. I genuinely love how it makes my hair look and feel after each use. My hair appears much healthier, smoother and more manageable than ever before. I received this product as a part of an educational promotion.


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.

- 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
