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...

Helps dry ends
Hair Type Straight Hair
I use this before shampoo and it's easy to work through my hair. The texture is creamy but not heavy, and it rinses out clean. My hair feels softer and less dry after washing. It's not life changing, but it's a nice boost if your hair needs a little extra care.
I love the new n3 plus
Hair Type Wavy Hair
I have been an Olaplex user for a while it has seriously done my hair so good I still had a bit left of the other one so I was able to use both! I love their new formulation! My hair is shiny!

Softer, Stronger Hair in Just 3 Minutes
Hair Type Straight Hair
I've been testing Olaplex No.3 PLUS for about a week now, and I was honestly surprised by how noticeable the difference was after such a short treatment time. I applied it to damp hair before shampoo, focusing on my mid-lengths and ends where my hair is the most dry from coloring. The texture feels smooth and lightweight, and it rinses out clean without leaving any heavy coating. My hair felt softer even while wet, which for me is usually when it's the hardest to detangle. After blow-drying, it looked smoother, less frizzy, and my ends felt stronger instead of brittle. I also really love the scent - it's fresh and subtle, not overpowering. After a few uses, I've noticed less breakage when brushing and my hair just feels healthier overall. It's an easy step that makes a visible difference in softness and manageability. Received as a part of an educational promotion.


Not sure if this is for me!
Hair Type Wavy Hair
I have loved Olaplex products for a long time, but I'm still on the fence about this new product. I'm not sure if its the formula, but something didn't seem to sit quite right with me hair. It almost felt more dry after use, even after a blow dry with heat protectant. I might need to use it a few more times or pair it with other Olapex products, but unfortunately this did not impress me on the first few uses. I really wanted to like it and I'm wondering if others are disapointed with their results from this product.
Smooth hair
Hair Type Wavy Hair
I absolutely love this product. My skin felt smooth, soft, hydrated and very light with first use. I love the smell, it is fresh and nice. The product is easy to spread it across hair, the hair het sleek and smooth immediately. I sprayed some water on my hair to make it wet then left the product on my wet hair for 15 minutes. Then followed up with Olaplex shampoo and conditioner. My hair felt so soft and smooth immediately. FYI I have a really dry and frizzy hair and it tamed my frizz really well.
