I have been using the Act + Acre 3% Stem Cell Peptide H3-Grow+ Complex™ Scalp Treatment for Hair Thinning + Growth for a while now. Although it is still relatively early, I already feel like I am seeing a noticeable difference in the overall appearance and health of my hair. I have noticed less shedding and significantly less hair left behind on my brush. I have also been wearing my hair in braids more often lately, and I feel that my braid looks fuller and more voluminous. I have even received more compliments on my hair recently, which has been especially encouraging. The product is very easy to use. I simply spray it directly onto my scalp once a day and massage it in gently with my fingertips. It leaves my scalp feeling cool and slightly tingly, and I can style my hair as usual afterward. I am very happy to have found a product that has made such a positive difference in the way my hair and scalp look and feel. I am excited to continue using it and see how my results develop over time.

Amazing

This is my favorite hair product. I’m on a GLP-1 and I’ve lost 183 pounds. Of all the products and serums I’ve tried I feel like this one has been the most effective. My hair feels fuller and I’m seeing decreased shedding. I love the nozzle for easy application. Get this!!

The act + acre 3% stem cell peptide treatment h3– grow + complex is worth the price to help with hair thinning issues. As I’m getting older I’m having more thinning in the corners of my forehead and overall increased shedding. Since using this product, I’ve definitely noticed less hair shedding. With continued news I’m confident I’ll have more density and fullness to my hair. It’s very easy to use, you rub it into your scalp and it absorbs nicely without leaving any residue. I’m excited to see the results with long-term use.

Like it!

I’ve been using the Act+Acre’s 3% Stem Cell Peptide Treatment because I’ve been dealing with more hair shedding than I’d like. I apply it directly to my scalp and massage it in, and I love that it feels lightweight rather than oily or heavy. It also doesn’t leave my hair looking greasy, which is important to me since I don’t want a scalp treatment to interfere with styling. The combination of peptides, caffeine, and botanical stem cells makes me feel like I’m giving my scalp some extra attention and care. With consistent use, my hair has been feeling healthier and looking fuller, particularly around the roots. I also appreciate how simple the application is. There’s no complicated routine or lengthy process—I can work it into my scalp in just a few minutes and move on with my day. That makes it much easier to stay consistent with it. After using it consistently, I’ve noticed less hair coming out when I wash and brush my hair. My hair also feels a little stronger and healthier overall, especially around the roots.

Finally Seeing Less Hair Loss

I’ve been using this scalp treatment for a few weeks and I’m genuinely impressed. I used to notice a lot of fallout when brushing and washing my hair, but now it’s noticeably less. My hair feels thicker at the roots and overall looks much fuller, which I love. It’s lightweight, doesn’t make my hair greasy, and is super easy to use daily. Definitely feels like it’s making a real difference over time.

Great product

Great product! I have noticed a big difference in the growth and shedding of my hair. Noticed new growth in thinning areas. It is light weight and doesn’t leave a weird texture on my hair/scalp.

Absolutely worth trying

I receive this product complimentary from actacre, but I’m so happy to receive it. I’ve been using the Act+Acre 3% Stem Cell Peptide H3‑Grow+ Complex Scalp Treatment for a little while now, and it has quickly become a staple in my routine. The biggest changes I’ve noticed are in hair fall and overall density, and the experience has been genuinely impressive so far. This scalp treatment fits seamlessly into a routine and delivers visible, feel‑good results. If you’re focused on scalp health, reduced fallout, and fuller‑looking hair, this is absolutely worth trying.

Great hydration

I recently started using treatment and love how it leaves my scalp. It's light weight and non greasy which I like. It has a minty scent which I love. My hair feels nourished and hydrated instantly. I have realized less shedding and excited for the up coming weeks for more change and hair growth.

Hair feels fuller and healthier

#gifted by actacre I’ve been using this scalp serum consistently and I’m really impressed with how lightweight and comfortable it feels. It absorbs quickly, doesn’t leave any greasy residue, and layers well with my routine. After a couple of weeks, I noticed less shedding in the shower and when brushing, and my hair feels noticeably fuller at the roots. My scalp also feels balanced and hydrated, not tight or irritated. If you’re looking to support healthier-looking, thicker-feeling hair over time, this is a great addition to a consistent routine.

Healthier Looking Hair With Noticeable Fullness

After consistently using this scalp treatment I’ve noticed a clear reduction in hair fallout and my hair feels stronger from the root. Over time my strands have started to feel thicker and my overall hair looks fuller, especially around areas that usually feel flat. The formula is lightweight and absorbs easily without leaving any greasy residue, which makes it easy to keep up with regularly. My scalp feels balanced and refreshed, and my hair just looks healthier and more dense with continued use.
