Hair should be treated like a fine  fabric similar to silk , When age adding to much heat the hair it can use more damage than most people think.

1. Always keep your blow-drying from getting lost in the vents
2. use protective cream or protective hot spray to prevent further damage
3. use a mask at least twice a week to ensure the hair gets proteins check the setting on your hot irons
4. 5. section the hair with the part that you want , I recommend taking pie sections its much faster and the hair will flow better where curling the hair.
