I love
I have been trying the 4% Niacinamide Oily Scalp Serum from Act+Acre and I have loved the results. Since I incorporated it into my routine, my scalp feels much less greasy and the hair looks clean and fresh for longer.

Amazing
I absolutely LOVE this scalp serum!! It’s lightweight, easy to apply, I’ve actually been able to extend wash day. If I use it in the morning on dry hair, the serum also gives my hair more life and volume after I rub it in, which is an unexpected bonus for my fine hair.

I've been using this scalp serum for a couple of weeks and have noticed that my scalp feels much less oily between washes. The formula is lightweight, absorbs quickly, and doesn't leave any greasy residue in my hair. My scalp feels fresher throughout the day, and my hair looks cleaner for longer. It's easy to apply and has become a nice addition to my hair care routine. Overall, I'm very happy with the results and would continue using it.

Wow!
I have the Actacre Niacinamide Oily Scalp Serum! I can’t believe this stuff actually works. I always have oily hair right at my scalp. But with this stuff it really dried it out and made a huge difference!

Terrible! Do not buy!
Terrible! Does the exact opposite of what is advertised! I followed the directions, putting 2 pipettes throughout my CLEAN scalp (mid-length hair) on freshly washed damp hair prior to blow drying. I have oily hair; it usually stays looking clean/freshly washed for 18 hours or so. The photo is 2 hours after using the product on my clean hair. My freshly washed clean hair now looks like it does (or worse) on day 3. This is the worst product I’ve ever used on my hair. Do not buy!!!!

It really does work
I’ve been using the Act+Acre 4% Niacinamide Oily Scalp Serum and it’s made such a difference in how my scalp feels. Less oily between washes, way more balanced, and my hair just looks fresher longer. It’s lightweight, doesn’t weigh my hair down, and actually feels like skincare for your scalp.

I love it
I love using this! I have oily scalp and it comes pretty quickly after showering. This has helped delay how quickly my scalp gets oily. It’s so easy to use and doesn’t weigh down hair. It’s great for all hair types.

I have been using this serum for a couple days and I am already noticing a difference. I have fine hair that gets oily quickly, and this serum is slowing the time between washes. It’s refreshing to use a product that does not irritate my scalp or weight down my hair.

Skincare
It’s powered by niacinamide, so it feels more like skincare for your scalp than a typical hair product. I also like that it absorbs fast and doesn’t leave any residue, so I can use it on non-wash days without worrying about buildup.
