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! Read more

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 Read more

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! Read more

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.
