Before I tried this product, I viewed Olaplex as a brand for people who were born with good hair and just went to the salon to drop a few c-notes to get a touch up. I'm not one of those people. With hair, I am very low maintenance, preferring to wet it and forget it (antithetical to Olaplex in my ...

Not for me
I really wanted this scalp treatment to be a win, especially since I usually love Olaplex' products. Their shampoo and conditioner have been staples in my routine for a while, so I had high expectations going into this. Unfortunately, it didn't quite deliver on what I needed it for. To start with th...

Hydrating and nourishing to scalp
I have been using this product for almost a month, and I really like how it feels on my scalp. It gently nourishes and hydrates skin. It has no scent and doe snto feel greesy on the hair. The product absorbs fast and does not weigh down the hair. A little bit of product goes a long way. This product was provided for promotional purposes in exchange for my honest review
My hair looks and feels healthier!
I have struggled with a dry scalp and postpartum hair loss for a little while now, so this Scalp Longevity Treatment from Olaplex was right up my alley! At first, I did notice a slight tingling sensation when using this product, but after using this product regularly, I did not notice it again. After applying this scalp treatment to my freshly washed, clean hair, my hair feels noticeably smoother, looks healthier, and there is less frizz! There was also a huge improvement with my hair shedding, my hair has not been falling out nearly as much as it was before I started using this. This scalp treatment has also helped reduce the overall flakes on my scalp that I tend to get, and I love how my hair will still feel fresh and clean like I just washed it even days after applying this! The only real critique that I have is that I noticed the product was nearing being empty after two weeks of consistent use. With that being said, this is still such a phenomenal product and a great addition to my hair care routine. (Product received in exchange for my honest review)
Soothing Scalp Reset in a Bottle
After just one use of the Olaplex No.5 Scalp Longevity Serum Treatment, I noticed a visible reduction in the small flakes I sometimes get on my scalp. It instantly soothed and hydrated without feeling greasy, and after four weeks of consistent use, my scalp felt healthier, more balanced, and noticeably more hydrated. My hair even felt a bit softer and looked shinier, which I didn't expect from a scalp treatment. I love that it targets both hydration and long-term scalp health with ingredients like ceramides, fatty acids, and antioxidants. It's also super lightweight and easy to apply. I'm giving it 4 out of 5 stars—not quite life-changing, but a solid addition to any routine if you're looking to improve scalp health and overall hair quality.

Scalp feels hydrated
Olaplex scalp treatment works well, leaving your scalp feeling hydrated instantly. Easy to apply and a little goes a long way. Only down is size of bottle but you do get multiple uses out of tube. "This product was provided for promotional purposes in exchange for my honest review,
Super light serum!
Been using Serum for 30 days. My scalp used to be flaky, and this cut that down a lot. An unexpected perk? My blowouts last longer now since my scalp isn't as oily. It's super light, not greasy at all. Product provided in exchange for honest review.
