Dr. Groot Hair Thickening Shampoo, Korean Hair Care with Biotin, Rosemary Oil to Help Volumize Thinning, Damaged Hair, Hydrate Hair and Scalp, Biotin Shampoo, Scalp Revitalizing Solution

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!

At the risk of being redundant, this stuff is amazing. I'm 62, with thinning hair and on a glp-1. I never thought I'd see a shine on my hair again. This. Works. Something about the texture and feel on the scalp just makes you want to massage it in forever. It smells very faintly of lovely rosemary. And in connection with the root revitalise, it leaves my hair looking and feeling thicker, and so shiny even my darling oblivious dad asked what's different. I've been using it the combo for a month now and just got my hair cut and highlighted. My stylist asked what I've been using! It's expensive, but worth it. A definite repurchase.

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.

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!

I have very fine hair and working out makes it a challenge. Dry shampoo doesn't work great for me. I find its a light shampoo and used with the hair strengthening serum, its not as dry.
