I have curled, straightened, and hot combed this wig and I’ll say it can take the heat! I am a beginner to wigs so I watched many tutorials on which would be best to start on. I have on the 20’ 13x4 lace frontal wig. It fits comfortably on my head surprisingly! I cut it and it’s still long in length on me. I over bleached the frontal so I’ll be sure to more careful about that next time. Overall, I recommend this wig!
