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!

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.

The media could not be loaded. I’m pleasantly surprised by the results of this product! The serum has a lightweight texture, doesn’t weigh my hair down, and absorbs quickly. After just a few days of use, I noticed my hair became less brittle and the shedding reduced significantly. It has a gentle, non-overpowering scent, and the dropper is very convenient to use. I will definitely continue using it — my hair finally looks healthy and full of life. Highly recommend it to anyone struggling with hair thinning!

Love love love this product! I had a balding spot where my part was for years, and now I have a few inches of hair growth there instead. Works great, does take some time tho. I’d recommend using for at bare minimum 60 days before deciding on anything. Good value for the money. Clean ingredients for hair growth.

I’ve been using this hair growth serum every day for a month, and I really like it. The dispenser is super convenient, there’s no smell, it’s not greasy at all, and it works! My hair stopped falling out, it feels healthier, and I can already see some baby hairs growing. It definitely worked for me.

This is one of those products that seems to work if you use religiously. Better off getting to the root of the problem.....see what I did there. 🤣🤣🤣

It ruined the results of minoxidil. My hair had become thicker after minoxidil, but the greed for long hair after seeing the advertisements for this product made me buy it and try it. I used it for nine days and it made my hair fall out horribly. I thought it was temporary, but every day the same amount falls out three times. I feel sad about my hair. It even made my baby hair fall out.
