Today I used Curl Keeper by itself, and..
I got great hair. Great! I am very happy. I realize that in the summer and humidity (I live in Wisconsin), this may not be the case, but for right now it is actually better alone than with a Biotera product for styling. Its really great to only have to use one styling product. I was hesitant to use it alone until Gretchen said she uses it alone. Thank you, Gretchen! and Ashley from frizzoff.com uses it alone also. I would encourage others to try it!
