I was having issues with my hair, falling out and thinning. I started using this and started noticing a difference within three weeks and now my hair feels like it’s starting to get back to normal. I loved this and I don’t want to stop using it.

After using this product for only about a month & a half, i’ve noticed hundreds of new hair growing in from my scalp! It also scores high on the Yuka app which reassures the ingredients are great for scalp and overall health! Very pleased and excited for more results!

After the GLP1 shot, I did notice thinning going on so I'm hoping this will work along with the shampoo and conditioner to restore my hair to what it once was. I have confidence in Monat to achieve this.

this serum is a daily non-negotiable in my routine. Mind you this bottle also lasts me at least 3 months! It’s non greasy & can be used on wet or dry hair. I’m mind blown what two years of consistent can do 🤯 #hairtransformation #thickhairtips #curlyhairtips #scalptreatment

I’m here to help simplify hair growth for you. And I’ve done the testing to see what works so you don’t have to! The products that I used to transform my hair have been clinically tested. They’re also naturally based and do not contain compounds like minoxidil or finasteride. Think of it like vitamins for your hair & scalp. My products promote ultimate scalp health. This is where the growth happens. If your scalp is suffering, you can’t expect your hair to thrive and grow at its maximum potential. I’ve used these products for over 10 months now and my hair continues to improve month after month! My thickening serum is packed with powerful & natural ingredients like caffeine & melatonin. Not only will it help you reduce shedding up to 92%, it helps wake up your hair follicles to stimulate growth. It’s a daily step I never miss! My thickening shampoo & conditioner also help reduce shedding & breakage by 80%. They help strengthen and fortify the hair strands while removing buildup that can block follicles of new growth. Ready to make the switch?  Not only will you address your thinning, you’ll also help with length retention and overall hair health!  #hairgrowthproducts #hairgrowthjourney #hairgrowthoil #hairgrowthhacks #hairgrowthoil #hairgrowthtips #hairgrowthprogress #hairgrowthsolutions #vegan #veganhair #lowtoxliving

Poder recuperar la vitalidad y densidad de mi cabello ha sido un proceso que siempre comparto porque se exactamente lo que se siente perderlo de manera excesiva. Acá te dejo el suero que me ayudó a recuperar mi melena y cómo lo vas a aplicar a diario o día si/otro no. #densidadcapilar #cabellosano #cabello #detenlacaida #suerocapilar
