Awesome product.
I have Lupus and RA, this product absolutely transformed my hair. So much of my hair fell out and it wasn’t growing. Not only is it growing. But my hair feels fuller. I now use it all the time along with the shampoo and conditioner.

Great quality but Not enough product. Super sad that it ran out after my 3rd or 4th use.
It didn’t even last me a week. I didnt over use it just a few pumps. From the three or four times that I used it seemed great and easy application but again it was out after my 3rd or 4th time using it, it was empty. I switched to lilyeve. I would’ve loved to continue using the product but because it ran out so quickly and the price for it.. I can’t. Maybe if the company reached out to rectify I would switch back. Not sure if that’s normal. Thought it would maybe last me like three weeks to a month. Super upset because I really enjoyed it at first.

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.😊

Too little product for the price
Very little product for the price, I was using it bi-weekly unlike daily like most recommend. If I had used it daily I would have been out of product by the end of a week. Also should add, I’m not using a lot of product either, I’m using it on one specific spot on my head. So using that little of product and using it only twice a week and it runs out after a couple uses? Maybe I got a bad tube, but I’m not going to spend near 30 dollars every couple weeks to see results.

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.

EMPTY
This thing comes basically empty. Don’t buy unless you have the money to get one per week. Mine only last a little over a week.
