Turns out my roommate had Epsom salts, so I tried mixing them with SNC conditioner. So far its a success! Two washed later and my hair is bouncy, super shiny, not weighted down, and holds its curl MUCH better. It is a little frizzy by the end of the day, I think the salt is drying it out, I might back off on the amount of salt used and be sure to deep condition.
Added bonus, my hair survived a full day of 97% humidity and cold, drizzly, rainy weather with minimal frizz
Thank you for all your help!
