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...

I am trying to make gets healthier and longer, and with it treating my scalp makes my hair getting healthier since when it starts to grow. Like the product doesn't leave my scalp coara and iT is easy ti apply
Honestly pretty happy with this product
I received the Olaplex No.5 Scalp Longevity Treatment for free in exchange for my honest review, and I used it every single day for 28 days. My scalp has always been kind of high-maintenance—prone to dryness, tightness, and occasional flakiness—so I was excited but also a little skeptical at first. Right away, I liked the texture; it's super lightweight and absorbs quickly without leaving my roots greasy, which was a huge plus since I have fine hair. The applicator made it easy to target dry spots, and the light, clean scent was really refreshing. After the first week, I started noticing less flakiness and that annoying itchy feeling basically disappeared. By the end of the 28 days, my scalp just felt healthier overall—more hydrated, calmer, and not as reactive when I used dry shampoo or styling products. I didn't notice a dramatic change in my actual hair growth (and wasn't expecting to), but my roots did feel softer and less oily between washes. It also didn't interfere with styling at all. The only downside is the size—since I used it daily, I went through the bottle fairly quickly. Still, a little does go a long way, and I think if I use it 3–4 times a week instead of daily, it'll last longer. Overall, I'd say it's definitely worth trying if you struggle with scalp issues or just want to give your scalp some extra care. I'll be repurchasing for sure.
Lightweight scalp treatment that feels refreshing
I've been using the Olaplex No.5 Scalp Longevity Treatment for a couple of weeks and I'm happy with it so far. The formula is lightweight and doesn't leave my scalp feeling greasy or heavy. It's easy to apply, absorbs quickly, and gives a nice refreshing feeling. My scalp feels more balanced and less dry. I also noticed less itchiness. It's a nice addition to my haircare routine, especially if you want to focus on scalp health. I'm excited to see more results with longer use.

Nice product
I really like this scalp serum! It feels lightweight and refreshing, and my scalp definitely feels calmer and more balanced after using it. I noticed less flaking and irritation within a couple weeks. My hair even looks shinier and a bit softer, which was a nice bonus. Just be careful not to use too much—if I go overboard, my roots look greasy and heavy. A little goes a long way, so I just apply it in a few spots and massage it in. Overall, it's a great treatment if you're looking to keep your scalp healthy and your hair feeling fresh.
Great Product!!!
I have thick coarse hair and struggle with scalp psoriasis. This serum has really helped calm the irritation and reduce flaking. It absorbs easily and has no scent, which I really appreciate.
