Dr. Groot Award-Winning Hair Thickening Serum for Thinning Hair

Amazing it made my hair so thick and full on the first week I highly recommend the product line I love Dr. Groot ❤️❤️❤️

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!

Great product but the price is rough for the amount inside. I am purchasing again just wish it was cheaper or came with more.

I was really excited for this product but when using it the solution would barely come out and eventually stopped coming out completely. Huge waste of money since I barely got any use out of it. Seems like there is an issue with the packaging used to disburse the solution.

I was disappointed in this product and will not be renewing .

I think it works well, especially with the other products, bit jesus christ it lasted 3 days… and I used it sparingly…

I have fine hair, and had significant thinning around my temples due to styling and genetics. I've have tried a number of different products and this works the best. In 1 month, I've grown at least 1-2 inches of baby hairs. Although some of the new hair is gray, a win's a win! I have other family members that use the same solution and have seen similar changes. I also use this with Dr. Groot's Hair Thickening Shampoo, and Miracle In-shower treatment. When I was using only the Hair Thickening Shampoo, I didn't see much of a difference. However, when I added this serum plus the Miracle In-Shower treatment I saw an improvement with hair growth. Just fyi, it may take longer than 2 weeks to see a change. I'm not sure how folks are out of solution after a few uses. I wear this solution once a day and its lasted me a month already - and I still have plenty left. Perhaps to get the most of the product, when it's not in use, make sure that the pen stands upright and that you ensure the button to pump the is turned off to avoid spilling.

This product to me is not like a serum, which is a thicker liquid. This is like water coming out and it ran down my forehead right into my eyes and all over my glasses so beware before using this that it’s like putting water right on you. I wish I had been forewarned about that because any serum that I’ve used is thicker.

I have bought and used this serum multiple times previously and found this specific order to be inconsistent with what I normally receive. The liquid is completely thin and watery rather than the viscous gel texture I am accustomed to, causing it to leak through the rollerball applicator. The packaging print and barcode proportions also differ noticeably in sharpness and alignment from the authentic tubes I have at home. I have contacted customer support for a return and refund.
