It has sand or something in the bag, therefore the products were dirty. The serum was opened already.

Love this product 10/10. Been using it for a little while I use to have thin stringy hair that would always split this has helped my hair grow my shedding and my broken ends.

DO NOT BUY THIS!! Makes your hair come out in clumps!!! Picture below is just one wash. I’ve been using this for a few weeks and at first I was like it’s just bc it’s new but nope the amounts kept getting bigger so I’ve stopped using this product. I will stick with my DIVI products.

It works ladies and gents! I’m here to testify. I’m in my 50’s menopause phase and my hair was thinning and since using monat exactly how they say to use it. That is key for success. It’s spendy, but obviously 🙄 I’m still here paying for a product I know works so I pay. No more shedding/or thinning

Honestly if I could give zero I would. This has made my hair fall out IN CLUMPS every time I’ve used it, which is absolutely out of the norm for me. It’s caused me a lot of emotional distress and I’ve cried over how much hair has come out in ONE comb-through with my fingers after using. :(

I had some menopausal hair loss when I came across a video with a girl who had thick, long hair from using this shampoo. I was tired of my thinning hair and am so glad I bought this IR Clinical Thickening Shampoo & Conditioner Set. So far so good. My hair feels thicker, looks shinier and I love it.

Highly dissatisfied.. it came from the returns department when I spend that kind of money I don’t expect somebody to have used & returned it. there was actually a label behind my shipping label. The shampoo bottle comes out both ends of the cap and it’s wasted.there .

Love Monat! My hair looks and feels incredible, and for the first time ever I don’t need to wash it daily. I can easily go 2–3 days between washes, which I’ve never been able to do before. Highly recommend!

Extensions in a bottle. If you want thicker, longer, stronger hair that's healthy from your scalp to the ends of your hair - this is my haircare system that I've used for the last 6 years and leads people to believe that I wear extensions, weft or wig. People also say my "before photos" I box dyed my hair amongst other things so l'm explaining here about my transformation & the background of my hair. #hairtransformation #haircare #hair

I fear it’s going to keep getting thicker and longer actually 😜  To my post partum mamas, your hair does not have to fall out in astronomical chunks. I’ve been using a clinically backed hair care system for almost 4 years now and it reduces excess shed by 92%! Game changer for PP hair loss or anyone who struggles to grow their hair in the first place ♥️♥️♥️ linked! Xx

I’m just as floored😳 • I started out as the biggest skeptic. I wanted it to work…but I also didn’t think I was going to work OR have THAT kind of transformation. • Pairing the serum with my thickening shampoo & conditioner maximized the amount of hair on my head so much that it doubled my density and gave me insane volume. My hair also became more manageable, less oily and my ends stopped breaking off and splitting. • I’ve shown my hair journey since day 1 and taken you along this ride because I’m just as shocked as you. I want to show you what’s possible with the right products🩷 • I will not let anything else touch my hair because of what it’s done. And will continue to repurchase over and over with my own money. I was always first a loyal customer and I STILL pay for all my products • If you’re finally ready to transform your own hair, comment or DM me “TRIO” and I’ll get you set up on the exact system you need to get started. It’s on major sale right now! • #hairgoals #hairtransformation #hairgrowth #haircare #healthyhairgoals

Replying to @Ayla real people, real results, and real haircare that actually works  I get it, it’s hard to trust what you see on the internet because a lot of it is fake. But that goes against my beliefs to be promoting something and it be fake. I’ve been using Monat for many years now and the results speak for themselves. When you switch to clean vegan haircare that doesn’t clog your follicles and stunt hair growth, you will see results!  My most viral system is on sale, linked here and in my showcase  #shampoo #extensions #hairgrowthtips #healthyhair #monat

I thought postpartum hair loss was just something I had to live with… until I found THIS. 🫶🏼 After 2.5 years of consistent use, I’ve never felt more confident in my hair. 💁🏼‍♀️ Thicker, longer, fuller—and no more handfuls in the shower. 😭✨ #HairTransformation #PostpartumHairLoss #ThickerHairJourney #HairCareRoutine #MonatResults #HealthyHairTips #HairRegrowth #MomLife #HairGoals #monat
