Update: Help! Curls went flat after trip to AZ
Thanks for your advice, SaraNoH and JRock. I did a deep treatment of half-honey/half-coconut oil and left it on for maybe 40 minutes (shot it with the blow dryer near the end). I washed that out with sulphate-free shampoo and conditioned with sulphate-free conditioner and added honey to that. I invested in some new products (Deva Curl Arc AnGel and Set it Free). My curls look fantastic and despite the few pieces that are still suffering from being Arizona'd, things are looking up. Phew!!! Thanks so much.
