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!

Great shampoo, gently cleans and leaves your hair soft with your scalp refreshed. Too soon to test out the hair growth benefits.

I used a thickening shampoo before that caused a lot of buildup and made my hair feel weighted and gross. This does not do any of that although there is a little buildup. Regardless, my hair still feels very clean and light. I'm hoping to see improvement in my scalp health, and maybe even a little hair growth along my hairline. My hair does feel healthier. I don't know if it thickens it but it's still a good shampoo!

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!

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.

I first bought it off tiktok. I didn’t notice anything difference within two weeks as it claims but I wasn’t going to throw away a 30 dollar shampoo. So I kept using it and I love it. It took some time but I shed less and I have a lot of baby hair. My hair is naturally very oily so for me it didn’t cause my hair to become more oily.

I personally really love this shampoo, it actually makes my hair feel clean after every use. Definitely seen more growth and volume with using it and it does exfoliate your scalp. Reduced my itchy scalp and hair loss, definitely worth the money. The scent is nice too especially with being pregnant not too over powering on my nose!

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.
