Great for postpartum hair loss.
Have been using for postpartum hair loss and it works really well. Does not leave hair greasy and smells great. I've been using on my scalp line for 6 months and have a lot of new hair growth.

Good bye sticky-uppy-bits!
This stuff smells amazing. The bottle feels luxurious. It keeps you scalp feeling comfy and your hair looking thick and lustrous. But the big surprise? All those little hairs that tend to stick out along the hairline…somehow miraculously gone!

Amazing!
I was hesitant on buying this product and after doing my research and watching/going through a bunch of tiktok videos and ratings I am so Glad I bought it! It made my scalp so much healthier and cleaner. It doesn’t leave a greasy feeling and has helped with hair loss.

Pleasant smell, will continue buying
Only been using 3 weeks so no noticeable difference in hair growth. But compared to others I've tried, this one doesn't leave your hair greasy, easy application.

Migraine central
This product gave me two migraines and multiple headaches in one week. Mine does not have a scent, but it is clear this is not a product for me.

I will update later if I notice changes - updated
I purchased this serum April 9th so I have only been able to use it about 2 weeks and I can’t say I’ve noticed much of a difference. My hair fall still seems a bit excessive but I know these things take time. I will say that the serum smells super good and I can apply it daily without it making my hair oily. My scalp is still dry and a little flaky even after using it though so I’m thinking of switching shampoos. I will definitely come back if I notice a difference or lack of one, but I certainly hope I see something for the price. Update: I used up the bottle a couple months ago and I wasn’t very impressed. For 52 dollars, I expected to at least see an improvement in the dryness of my scalp and overall scalp health like it says it will, but it didn’t feel like it did anything. I didn’t notice really any new growth or lessened shedding. The one thing I did like was that it was cooling on the scalp and very lightweight so it didn’t leave a heavy residue feeling like other scalp serums. But I won’t be purchasing again.

Smells amazing. I mostly apply after washing my hair. I believe it also helps with hair falling too. Can see some baby hair. Just need some time to observe
