Thanks for all of the ideas and advice. I am using Tresemme Naturals with La Looks (when the dewpoint is between 40-60) and HE Set me up, the old version (when the dewpoint is above 60). I also use IAGirl's PT.
I went to Sallys and bought the colorful neutral protein filler... I was pretty pumped to see the different proteins listed in the ingredients. Hopefully it will do the trick. Thank you so much!!
