Review: Before and after - Amazing it made my hair so thick and full on the first week I highly recommend the product line I love Dr. Groot ❤️❤️❤️
Review: Barely anything in it! - Don’t be fooled by size!!! I never review things, but here I am. Listen to the other ppl saying it doesn’t last! Bc it doesn’t! I used this for 3 days! 3!!! It two small sections of my head-the front temple areas-morning and night. Went to use it this morning-completely gone. It did not leak. I have tried everything to get a drop out-nothing. It gave me one tiny pump and then nothing but dry. I really liked it bc it didn’t turn that section of my hair oily like others, and it didn’t leave a residue. But the amount of money it costs, for it to not even last a week, is extremely frustrating! I can’t imagine ppl using this long term!

### ⭐⭐⭐ Not enough product
*by A***A on August 18, 2026*

Ran out by the 5th use.. for the price unfortunately it’s just not worth it. I mainly used it for the sides of my scalp and the back but in order for the product to be saturated properly on your scalp you do have to use your hands. I like the concept but of the pen and how it’s supposed to stimulate hair growth on the scalp using the roller but you’re better off finding a product & scalp tool that can go a lot further for your money/time.
