100% will not use any other hair care products after using the Dr. Groot hair care system! I know it’s a bit on the pricey side, but it’s worth every penny. It smells sooooo good and it leaves your hair feeling so much fuller and softer. It lathers really well, especially if you get a scalp massager to go with it. It has the best Korean hair ingredients. It is very effective! I’ve noticed a huge difference in shedding since using this. 10/10 recommend!

This is by far one of the best shampoo that I am in love with lately! You can see it from the very first wash! Best for scalp and thicker hair to grow out stronger! also adds natural volume from the very first wash!!

I bought this shampoo in July of 2025 and barely fished it today January 29 ,2026 a little goes a long way and it does feel like its drying out your hair after it’s rinsed out but I did noticed a significant amount of hair growth my hair feels and looks more healthy and shiny I had a few bald spots and light hair around my hairline and now my hairline is full of hair and so much thicker I didn’t like the scent but after it’s dry it smells amazing the price was definitely worth it considering how long it lasted me and the new growth I also noticed my hair feels stronger and I had way less hair fallout it has made a huge difference and I love that you can feel it working on your scalp

I’ve been using the Dr. Groot Hair Thickening Shampoo for a few weeks, and my hair already feels noticeably fuller and healthier. The formula lathers nicely without feeling harsh, and it gently cleanses my scalp while nourishing the strands. I love that it contains botanical ingredients that strengthen hair and support scalp health, so my hair feels thicker without any heaviness or residue. After each wash, my hair feels soft, bouncy, and more voluminous, and I’ve noticed less breakage too. Honestly, it’s become a must-have in my routine for maintaining fuller, stronger hair — definitely worth trying if you want your hair to look and feel thicker!

I wish I knew about this brand sooner, my scalp health became better overtime in combination with the their scalp serum. I used other products as well with dandruff control, but this shampoo made the greatest impact and my scalp became less oily over time. For the price it's pretty expensive for the amount you get.

Now this stuff WORKS!! I got the whole set, and WOW is my extremely thin hair so much thicker everytime I wash it. I'm on something that causes hair loss as a side effect, and this is the ONLY thing that has helped with my hair, and you name it, I've probably tried it. Vitamins after vitamins, this hair serum, that hair shampoo... just about EVERYTHING! All I can say is give this a try. I know the whole kit can be pricey, but according to little ol' me, IT WORKS!! My hair is healthy, feels great, isn't dry, has volume and makes me feel pretty again.

Thank you so much I love your products. I heard about your products from my hair stylist she been using on me and I have less hair falling out and hair feels fuller and shiny thank you Dr Groot 😊

Truly loveeee the Shampoo and conditioner. I was not expecting me to like it this much that I’m even considering going to Costco in hopes of finding the bigger sizes. I love the smell, almost spa-like. I love how clean the shampoo makes me feel after washing and how minty the conditioner feels on my scalp. You can definitely feel the scalp care working its magic.

Favourite product. I haven’t noticed as much thickening but I definitely shed way less.

Après seulement deux utilisations, ce shampooing est incroyable : j’ai tout de suite remarqué la différence ! Mes cheveux sont plus épais, plus doux et paraissent vraiment plus sains. Le prix en vaut largement la peine.

Up to the standard

Expensive but effective. This product is very special. I have only used it one time since it's delivery and I can already see and feel differences in my hair and scalp. Can't wait to do further shampooing

Nice shampoo. It smells nice ang really makes my hair feels softer. Its really effective its a bit expensive but really worth it.
