It Works

I was pleasantly surprised to find this new product to be very effective in thickening my hair after one use, and with continued use, I have seen better results. My hair was beginning to thin and after trying other products with minimal improvement this conditioner has helped.

Have been using this product for a few weeks now and I don’t feel my hair is noticeably changed enough for a before & after photo, however my scalp feels much healthier and my hair feels a lot fuller after drying. Looking forward to seeing the long term results!!!

Great Conditioner!

I really like this conditioner and how my hair felt after using it for two weeks. It gave my hair moisture and didn’t leave my hair looks heavy and weighted down.

So soft! After I shampoo my hair I ust Dr. Groot's Hair Thickening Conditioner and leave it on while I do everything else I usually do in the shower. Just the perfect amount of time! My hair is softer than I would of ever thought. I tend to have dry and hair on the thinner side, but since I started using this product, my hair is so much better. Definitely recommend to friends!

An amazing luxury product

I am highly impressed with this product and will definitely recommend this to the next person. It made me feel extremely invigorated after from using the conditioner. I love the way that It made my hair feel after. It was extremely soft and really lives up to its name of reducing scalp buildup after one use because I could totally feel it. My main overall favorite of the product is the smell, and that is not so overwhelming. It's a subtle smell of Rosemary. I've yet to see the benefits of the biotin but I'm sure I will over time, it's been about a few uses for me so I have about a half of the bottle left.

After using this conditioner for the past few weeks, I feel like I really notice a difference in my hair! My scalp feels clean and I feel like it does make my hair look thicker.

Must have!!

I’ve been using Dr. Groot Conditioner for a few weeks now and here’s my honest take: It definitely makes my hair feel softer and look a little fuller right after I use it, which I love. It’s lightweight, so it doesn’t weigh my hair down or make it greasy, especially on my scalp. I also noticed my hair looks shinier and a bit healthier overall. That said, it’s not a miracle product. I didn’t see any major hair growth, and if your hair is on the drier side, it might not be moisturizing enough on its own. For me, it works best as more of a strengthening/volume conditioner rather than deep hydration. Overall, I like it for everyday use—especially if you have fine or thinning hair—but I wouldn’t rely on it for major repair or growth.

I really enjoyed this product! I tried to use it for a while before writing a review, but I feel this may need more time than I’ve given it. However, during the time that I’ve used it, it’s left my hair feeling super soft. My scalp is often very dry and I alternate between dandruff treatments depending on what’s going on. My scalp and hair felt very hydrated. The smell is slightly masculine, but not in a bad way. It’s nice versus all the floral scents there typically are in hair care.

This smells so good, but unfortunately did not hydrate my hair enough after shampooing.

The smell is too much to get passed.

This smells SO strong! I actually love a rosemary scent. This did NOT smell like rosemary to me. It smells like a strong men’s cologne that a guy has drenched himself in because he’s trying to cover BO. It hav me a headache and two days later I can still smell it. Pass if you’re sensitive to strong scents.
