Rooting Troubles My Baby Has scales

Please help I am a newbie and this is my first time rooting. I have kyra halfway done and the hair looks great. My problem is, her head looks scaley where I rooted the on the head it has turned a white scaley color and rough texture. Really bad at crown (swirl) nap of neck and forehead. What the heck Im I doing wrong? I know she is ruined but I am not giving up finishing her if even just for practice on rooting. Please help with any advice.
Thanks Connie

It sound’s like either you paint or matt finish was not cured all the way and is flaking off.

Thanks ladies I will try that. I have been wondering if my themometer is acurate. I will get a new one today. Ill keep you posted
