I have texturized and demi-permanent colored hair and this morning, I'm going to put it into a straight style. I shampooed with my favorite, Humecto Detangling Shampoo and conditioned with Olive Oil Cholesterol. I have hair serum (Frizz Buster) and Leave-in Conditioner by Razac. I put the serum in first and then the conditioner and combed thru, is this right? Also, I've been air-drying so it's thick but looser curls at this point (I have shorter hair) -- should I blow dry first then flatiron, or could I go straight to the flat iron? I have a CHI flat iron so I've heard this is possible. I want to use as little heat as possible but I also want it to look smooth. Any tips would be great!
