Great Healthy shampoo with great smell
great shampoo I saw this by Jackie hill and I had to try it and I was not disappointed at all. I recommend it if your hair falls off alot . it’s made a difference on me. Smells minty and it’s refreshing. makes your hair feel healthy. helps with volume too.

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

Not a lot of buildup like other thickening shampoos
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!

Dr. Groot: 4/5 for Thinning Hair
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 works
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.

Game Changer!
This is the best shampoo system if you are losing hair due to GLP 1 or perimenopause. I started to see results within two weeks as far as new hair growth and almost immediate stop of the hair fall from showering and brushing my hair. I have recommended to all my friends. I have always been someone with very super thick hair so when I was losing hair rapidly, I went through hair vitamins, oils, serums but this is the only thing that worked. Now my thick hair is on its way back.

Gentle Shampoo That Gives My Hair More Body and Life
Dr. Groot Hair Thickening Shampoo has been a really pleasant surprise and an easy five-star product. Washing with it feels more like doing something good for the scalp than just quickly cleaning hair and moving on.The lather feels rich without being heavy, and it rinses out clean so hair does not feel coated or waxy afterward. The scent is fresh and slightly herbal, the kind of “clean” smell that is noticeable in a good way but not overpowering or perfumey.After using it consistently, hair at the roots starts to feel a bit fuller and less flat, and the scalp feels cleaner for longer between washes. There tends to be less hair left in the drain and on the brush, and styling is easier because the hair has a little more body and grip. For anyone whose hair has started to feel thin, limp, or just not as strong as it used to, this shampoo fits easily into a normal routine and genuinely feels like it is helping well worth a full five star

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

Very impressed with this shampoo. I heard about it from a Jeff Lewis promotion and how much it reduced shedding and I’m shocked how well it actually works! Even from the very first use it has dramatically reduced the amount of shedding.
