Review: It works - I've been using this serum for almost a year now. This stuff really works, when used daily. I can see the new hairs coming out, shedding is substastially reduced, and my hair does seem to grow faster (not too much, but noticeably). It is expensive, so I always grab it when its on sale. And, if I'm inconsistent or stop using it, I notice my hair starts shedding again. I did try the shampoo/conditioner combo along with the serum but I don't think it made huge difference. So I only use the serum now.
Review: Pricey but seems to do what it promises - I'm not sure I can afford to keep using this... It lasted me about 3 months, but I only used it 2-3 times a week, not every day. I think it's helping, my hair is growing about ¾ inch per month, which is faster than average, and it feels thicker than before, but it's hard to measure since I have a pixie cut that I'm trying to grow out ASAP. But I'm also using a lot of other products, so I can't say for sure if this one is doing any good, or if it's the others. It's not greasy. It doesn't have a strong odor at all. I'll probably continue to get it as long as I can afford it.

### ⭐⭐⭐⭐⭐ Noticeable hair growth & less shedding – love this serum!"
*by D***H on July 9, 2025*

Amazing results in just a few weeks! I started using the MONAT IR Clinical Scalp Serum a month ago, and I’m honestly impressed. My hair was thinning around the temples, and now I’m already seeing less shedding and new baby hairs growing in. The serum feels light, non-greasy, and absorbs quickly. I love that I don’t have to rinse it out. I use it daily and give myself a quick scalp massage after applying — it fels so refreshing. Definitely worth it if you're struggling with thinning hair!
