I started using Vegamour GRO+ at the beginning of the year (January 2022), because I felt like my hair was getting thinner and coming out in the shower more than usual. I haven't noticed an insane difference or anything, but I definitely think it's thicker, fuller and I don't lose as much hair in the shower. It's easy to use, I just put a few drops throughout my scalp every night and then massage it in. It's a bit pricey but it lasts a long time. I'm 1/4 through my second bottle. I also got the dry shampoo and it works well!
Dry shampoo could smell better, I don't love the smell.
