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!

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

LOVEEE !!! my favorite shampoo of all time. wonderful mentholly scent. makes my hair feel super clean without being overly drying. i’ve noticed a considerable difference in my hair. however, it’s a bit expensive.

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.

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.

It’s only been 2 weeks but this has transformed my hair, I was switching between so many shampoos, it’s a 10, L’Oréal, Maui, and Ouai and all have made my hair feel so dry and brittle. I have scalp issues for like 3 months now that I’ve never had before like itchy, dry, bumpy and this shampoo made it all go away. I only use my Dyson air wrap to dry and style and it makes my hair very smooth, bouncy, frizz free and voluminous. I love it so much will be using this from now on. Will update review in a few months to see if noticed any hair regrowth or less fall out. Only thing I wish from it is that it smelled better, not that it smells bad but it’s light.

Love this brand. I got the set on a recommend from a friend, and honestly, it was the best decision. It IS a little pricey, but it works so well, I’ll buy it again. I suggest getting the system (it comes in a set of 4 products). Highly recommend.

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.
