This is hands down the best hair treatment for dry, curly hair ever! It's expensive but worth it. I got it for free with purchase in a PHYTO Sephora holiday kit. It has a milky texture and is meant to be left in overnight but I use it out of the shower too because it controls frizz and tames humidity issues. I'm hooked! It's in the blue bottle shown here. I only wish is had more fill weight because I have long hair and it wastes quickly.
