Easy to use and apply
I received this produce in exchange for an honest review. It is very easy to apply with the applicator, and dries down without any residue. There was no discernible scent as far as I could tell. I like that the active ingredient is safer for pets than other hair regrowing product ingredients since ...

Made my hair so dry
My hair reacted really poorly to it and I can't get it back to normal. It made my scalp so dry and my roots very sticky. I have very coilly hair, prone to dryness. It completely set me back :(

Best hair growth serum
Hair Type Wavy Hair
I love the ingredients such as pumpkin seed oil, Rosemary, and castor oil to help support a healthy scalp. Within weeks I noticed my hair was more healthy and thicker. It's also inexpensive compared to most serums and you can actually see results

Already see a difference
Hair Type Straight Hair
Bought this when it first came out and used as instructed for the last 2 months or so. Already have a night and day difference with my scalp feeling so much less irritated and less flakey. do recommend using it as directed on hair that's been towel dried versus fully wet or dry and that's when it won't feel sticky or greasy. it's fragrance free which is huge for me i hate when serums have weird smells but this is perf.
Affordable
