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.😊

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

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.

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.
F**F
it finished after a couple times only. So little u don’t get to see any result! Wouldn’t recommend
