Actually works
Love it!! I’ve bought it before and this is my second time using it works good. Worth the money but have to be consistent to see hair growth.😊

No worth the price!
Bad, bad, bad, two or three applications and it’s empty!! No worthy.

Amazing Product!!!
It is amazing I started seeing baby hairs after three days of just using it might sound like I’m faking it but I’m not my hair used to grow so fast keep in mind i am a male and after my hair started thinning and my hairline was receding I used this three days ago and I can tell a big difference I will absolutely be buying the shampoo and conditioner!!!!

Didn’t last long
I used this product for a week and it either ran out or isn’t working anymore as nothing comes out. I did not use a lot and I am so disappointed it ran out because I was hoping this would do the trick

Will update review once I see hair growth!
Love how it massages my head also.

Not enough product!
I didn't use this with the shampoo & conditioner, but even on its own it said that results will be shown in 2 weeks. However, the product didn't even last the 2 weeks to even show results. You're probably better off using just the shampoo & conditioner.

Dont buy the Serum
I bought this one, shampoo , conditioner and the scalp treatment. This serum is expensive for .5oz you cant even tell if it effective brcause you dont have enough. Among all the four products I only like the scalp treatment, the shampoo and conditioner makes my scalp flaky unless I used the scalp treatment. I can tell though it stop my haiross esp when my hair gets long.

Visible Baby Hair Growth
I’ve been using the Dr. Groot serum for a few weeks now and while it doesn’t last as long as I’d hoped (I usually need to reapply), I’m actually impressed with the results. I can already see baby hairs growing in areas where my hair was thinning, which is a big win for me. The serum feels lightweight and doesn’t irritate my scalp, and the growth results make it worth using despite the shorter-lasting effect. If you’re patient and consistent, this definitely shows promise for new hair growth.
