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!

Very happy, smells great and its smooth.

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 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

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.

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.

Loveeee this stuff no matter what I keep coming back to it. It grows my hair like crazy and I feel it gives it good volume! Everytime I use this shampoo it leaves my scalp feeling so clean and I feel like my hair is thicker after using two bottles I can definitely say it’s worth the price.

love the way this product smells and makes my scalp feel. It's only been the first use but already seeing great results with the quality of product. A little bit of product goes a long way so you will get great value for your money.

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

The bestttt I suffered with dry scalp for 4 years and this cured it

Totally worth it. Volume added and my hair was soft and easy.
