This wig is FIRE. It is in excellent unworn condition and still has its lace uncut. It starts out dark at the top and then as it goes down it turns into oranges and reds and then into yellows. Beautiful piece! The length is somewhere between 21 and 25 inches from the front. It has a comb in the back to help hold it in place. Synthetic hair. I do not know if it is heat friendly Smoke free/pet friendly home
