When I started out I had some heat damage on the ends of hair around my face. I had never dyed my hair or used chemicals but I did love my flat iron. I chose not to cut off the damaged parts until my hair grew. I have long hair, always have but I didn't want to just go chopping off a huge part at the front. I took care of my hair and when it grew in long and healthy I cut off the damaged parts. My curls are back curlier than ever and I hardly use heat on my hair now. I don't think you always have to go cutting off drastic amounts of hair at the first sign of damage.
