I have never tried Mystery Shampoo or Conditioner myself although the free sample page itself makes the product look very exciting and worth mentioning.

I received samples of the mystery shampoo and conditioner and love it. What is it called and where can I purchase it in Columbus, Ohio?
Best to contact the site and ask them what it was
thank you
