IR Clinical™ Hair Thinning Defense Scalp Serum – Nourishes Scalp, Reduces Breakage, Boosts Hair Density, and Supports Thicker, Fuller-Looking Hair with a Lightweight, Non-Greasy Formula

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.

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.

I can only speak to my personal experience and I have been taking this for two months (since Feb 2026) and am nearing the end of my second bottle. The regrowth has been undeniable. Minimal shedding now and my hair definitely feels thicker. I just purchased my third bottle.

I used this product for a total of 3 years, because I am dependent on daily Prednisone, which causes DHT to rise and hair to fall out. For about 1.5 years, this product worked to help my hair grow, so when in the second year, I started losing hair, and in the third year, tons of hair, I didn’t originally think it was the Monat, but it was. My scalp also became very itchy in the second and third year of use. I thought it may have been complications from the Prednisone, but the itching stopped when I finally figured it out and stopped using the Monat serum. Through all of this, I became educated on peptides. Capixyl (Acetyl tetrapeptide-3) is a peptide contained in this serum. Peptides are experimental synthetic pharmaceutical drugs, and can cause side effects. The Capixyl caused my hair to grow at first, but then caused it to fall out. I wonder if topically applying this peptide eventually causes an imbalance that leads to a decline in follicle function and health.

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!

Not worth the price. It’s very expensive for what it delivers, and the packaging makes it feel like you’re barely using any product. I didn’t see results that justify the cost.

Excellent product

I was very skeptical about this product, but since my hair seemed to be fitting on top, I wanted to give it a try. After about two months of use consistently, I have a ridiculous amount of baby hairs popping up all around my head which tells me it is working! This stuff is expensive, but I think any really good working hair growth serum is going to be expensive and the investment is worth it for me. I’m 35 years old and noticed my hair was starting to become slightly thin on top.

I don’t see results yet.. I’ve used consistently for a month and the bottle is starting to be empty, for the price I’m not sure if its worth it. I do have to mention when I just wash my hair and put the serum on, my hair looks voluminous so not sure, maybe it needs more time??

Lo pedí, pagué. Sólo cancelaron el envío, hicieron la devolución del dinero y le subieron el precio. No me gustó el servicio del proveedor. Sé que es muy buen producto.
