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 the best shampoo system if you are losing hair due to GLP 1 or perimenopause. I started to see results within two weeks as far as new hair growth and almost immediate stop of the hair fall from showering and brushing my hair. I have recommended to all my friends. I have always been someone with very super thick hair so when I was losing hair rapidly, I went through hair vitamins, oils, serums but this is the only thing that worked. Now my thick hair is on its way back.

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!

Maybe best shampoo and conditioner out there. It feels so luxurious and leaves your hair shiny and soft.

Month in: shampoo + serum daily= thicker roots, baby hairs regrowing in spots. Herbal scent, no irritation. Real progress, not hype—worth it for thin strands. Try if you’re shedding.

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

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.

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.
