Love it
I’ve been really curious to try this scalp serum because I’m focusing much more on scalp health lately. I use it after washing before blow-drying and at first I thought it might leave some residue on my roots, but it actually absorbs really well and my hair dries light, fluffy and separated. The texture feels lightweight and comfortable on the scalp and doesn’t make my roots greasy. I’m still waiting to see any noticeable difference in thickness or new growth since I know these things take time, but so far I really like how easy it is to add to my routine. I’ll definitely keep using it consistently and see what happens!

Amazing for Dry Scalps
This scalp serum is the most luxurious feeling product I’ve ever used in my hair and I’m loving it! My scalp feels so much healthier and hydrated after applying this every day and I swear I instantly notice a difference. It doesn’t leave any oily build up feeling, it just feels so clean and refreshed. I can tell Act + Acre is intentional about the ingredients they use which makes me love them even more. Plus, the aesthetic of this bottle is so perfect I keep it on my counter. I 100% recommend this!

Doesn’t last
Using way less than the recommended dose (1-2 pipettes) the bottle only lasted 2 weeks. For $55 it should have lasted the full month. 2 weeks isn’t long enough to see any results.

Hydrating and Lightweight Scalp Serum
I’ve been using this scalp serum daily and really enjoy how lightweight and comfortable it feels. It absorbs easily without making my roots look greasy or weighing my hair down. My scalp feels noticeably more hydrated, nourished, and healthy, with less dryness and flakiness. I also love that it’s a leave-in formula and fits easily into my daily routine. So far, I’m very happy with how my scalp feels and look forward to seeing the long-term results.

Not sure…
The bottle didn’t really last me a month, and I didn’t really see much difference.
It wasn’t greasy or crunchy which was nice.

my hair feels so much better
Lately my hair has been falling out so much, so I decided to try this scalp serum — and honestly, I’m really impressed.It leaves my scalp feeling super clean and refreshed, with a nice cooling sensation after applying. My hair already feels healthier and less heavy at the roots, and I’ve noticed way less shedding lately. Such a good addition to my hair care routine .
