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...

Aquí lo tienes perfecto para Ulta: corto, natural y creíble 👇✨ ⸻ I've been using the Olaplex No.3 for a few days and I can already see a difference. My hair feels stronger and looks healthier, not just softer like with a regular mask. I used it on damp hair before shampooing and left it on for about 15–20 minutes. After rinsing, my hair looked shinier and had less frizz. It's definitely more of a repair treatment than a moisturizing one, so I still use a conditioner after. Overall, I think it's worth it, especially if your hair is damaged or you use a lot of heat.

Not necessary for my routine
*received as a part of an educational promotion* I tried this hoping it would make a noticeable difference, but honestly I could take it or leave it. It feels like an extra step that didn't really change much for me. My hair didn't feel drastically stronger or healthier compared to my usual routine. It's not a bad product, just not something I feel like I need to keep using, especially for the price. If you already have a solid routine, you can probably skip this.
Love it!

I'm genuinely obsessed with this fast 3-minute hair treatment! It's such a game changer when you don't have time for a full routine but still want that "just left the salon" feeling. From the very first use, my hair felt noticeably softer, smoother, and way more manageable. Over time, I've seen a real difference in strength too — less breakage, healthier ends, and overall my hair just looks more alive. What I love most is how it doesn't weigh my hair down but still gives deep repair. My hair has been through heat styling and coloring, so having something that targets all types of damage is a must for me.

I am an avid Olaplex product user, so I was very excited to see them coming out with a revamped No 3 item. It is very similar to the original No 3, however I didn't have to leave the product on as long to see better results. After 5 minutes I was able to notice that my hair fell softer, and was a little more easier to manage while curly. This product seems very ideal for those of ethnic backgrounds, considering that it is a stormer version of the traditional item. I received this as a part of an educational promotion.


Love this
I received this as part of an educational promotion. I've been using Olaplex N°.3PLUS Complete Repair Treatment for a few days now and I'm actually really into it. It's super easy to add into my routine since you just use it before shampoo and leave it on for 3 minutes. My hair has been feeling a lot softer and looks way less dry, especially on my ends. I've also noticed less breakage when I brush it, which is a big plus. It doesn't feel heavy or greasy either, just makes my hair look healthier overall. Definitely worth trying if your hair is feeling damaged or overprocessed. Love 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
