  • Pricey but seems to do what it promises
Size: 1.7 Fl Oz (Pack of 1)
The media could not be loaded. 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. ... show more

  • It works
Size: 1.7 Fl Oz (Pack of 1)
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. ... show more

  • Good Hair Growth Serum
Size: 1.7 Fl Oz (Pack of 1)
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. ... show more

  • Noticeable hair growth & less shedding – love this serum!"
Size: 1.7 Fl Oz (Pack of 1)
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! ... show more

  • Works so good!
Size: 1.7 Fl Oz (Pack of 1)
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. ... show more

  • Bad sealing
Size: 1.7 Fl Oz (Pack of 1)
Not happy with my product, the serum was leaking. So the bottle and the box were sticky. I think is not fair I paid a lot for some serum be waited.

  • Works if use continously
Size: 1.7 Fl Oz (Pack of 1)
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. 🤣🤣🤣

  • Save your money
Size: 1.7 Fl Oz (Pack of 1)
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.
