I really like the hair product... It makes my hair feel refreshed and it even helps when I Wake up with bad hair day. It makes my scalp feel invigorated. It forces me to give myself a little head massage, which I know is good for my brain health.

It’s working?!
I lost a lot of hair after giving birth and I was starting to see a lot of my scalp. I’ve tried an handful of topical serums, shampoos, and even prescription pills and I haven’t really seen a difference in my hair growth in the past 3-4 years. After a recommendation from my sister, I tried the one skin serum along with micro needling and I’m now finally seeing little hairs sprouting!!!
