    Hair Renewed

    I have always had very fine, dry hair. Age certainly didn’t help. In recently years, I’ve found a good leave-in conditioner that has cured the dryness but other products (vitamins, etc.) didn’t make much of an improvement until OS-01 Hair. My hair feels and looks thicker and stronger. So much so that my husband who hasn’t even noticed color changes in the past has made comments (more than one!) about the appearance of my hair. It’s definitely worth trying!

    It works!

    I’m on my third bottle of the hair serum and I love it! I had been using Finasteride for over a year and it wasn’t doing anything! When I added the OS1 serum , my hair just started growing in the sparse areas. I feel my hair is thicker and looks better. Great confidence booster. I don’t know if OS1 works on its own, but definitely synergistically it works with Finasteride. It seems Finasteride laid the groundwork and OS 1 was the the catalyst! Will keep using both. Would love to try more products form OS 1. Suggestion for company., it would be great to receive a small sample of your other products along with purchases. I think it would be great long term client builder.

    I have been using OS-01 hair for a couple of months and can tell a difference in my hair growth. Lots of little baby hairs growing and hair is filling in.
