I rarely leave reviews, but this product has totally impressed me and improved my hair! I have been growing out my dry, frizzy, curly hair for and experiencing, shedding like crazy. This shampoo and “conditioner”, have made my hair feel soft, my curls are defined, it feels moisturized and bouncy. I absolutely love my hair. This product stopped me from cutting my hair! The shampoo has tiny beads that help clean the scalp and the lather is real. My hair is of full bounce, volume and shine. I say buy Dr, Groot, immediately! It’s worth every penny!

This shampoo smells AMAZING!!! it's cleanser my very oily hair so well! Did I mention that it smells AMAZING 😄 It has a clean, citrus fragrance. A little goes a long way. I have short hair and it use a little less than a penny-sized amount. I highly recommend that you purchase the hair serum/solution as well. Together they make a great team which leads to my hair feeling healthy. Highly recommended!

Have definitely noticed less hair loss when I wash my hair. Love the scent of this and it leaves my hair shiny and soft.

I have a dry scalp and this shampoo really helps. It creates thick foam, feels gentle, and leaves my hair with great volume after drying. As far as I know, it’s a well-studied formula from Korea made specifically for scalp care. Highly recommend!

Bretman Rock recommended! Been using for about 2-3 weeks and can already tell a difference. My baby hairs are growing like crazy. Make my hair shiny and smells pretty good.

This has been the best product for my hair. I have fine thin hair and this has really made my hair look fuller and healthier. Definitely recommend this and the serum

Be very careful when looking for thickening shampoo and conditioner. I heard about this one on TikTok but purchase here because shipping is faster. They advertise it for women with thinning hair. I've used a ton of different shampoos I found one that slows the process but the way they advertise this as if this was gonna be the one. I lost an extreme amount of hair. In the shower and throughout the day. That never happened until I used this product. The first time I lost alot of hair and thought ok that's probably just happens using it for the first time but nope 5 days later I use it again and I lost 2 times more than the first. This is absolutely the worst shampoo and conditioner I've tried. I'm so worried that I'm gonna lose more because after the first use I was shedding more than ever after washing my hair. Mind you I brush my hair before going in the shower and had a handful of hair so what you see in the picture isn't all I lost today. My hair got oily as well after day 2 no volume looks the same. I just don't like when people make false post just to make a sale. This is my honest review. Please be careful for the woman who has thinking hair. This didn't work for me and made it worst for me.

I have been struggling with alopecia areata many years. I tried Rogaine for several years but while it may have prevented future loss, it did nothing for the sparse area on my scalp so eventually I stopped using it and started to style my hair in a way to hide it. Recently I have had some health challenges that made me lose even more hair and I was feeling totally hopeless and started looking into hair surgery and wigs! I started seeing a lot of ads for Dr. Groot and yes I’m 45 and a fan of Bretman Rock and yes he “influenced” me but I’m glad he did. I’ve been using this product along with the conditioner for less than a week and my scalp feels amazing and my sparse area that I’ve had for at least 7 years is GONE. I’m excited to see what happens when I use the I shower treatment and the styling spray! I’ve been using Korean sunscreen, skin care, and makeup for many years and they are way beyond what we have in the US!
