Brown to beige blonde ombre wig measures 24-25" from the crown. I'm not sure if it's heat friendly-t's not shiny (which makes me think it might be heat friendly) but I haven't tried applying heat. only wore once in braids and it was adorable but it's too long for me and I'm not making use of it, so I might as well pass it on. fit is average to large. I'm a petite head with a 20.5" circumference and it's quite large on me. I was planning to wear it with a hat anyway since it has a hard front, so it worked. but if you were going to blend your own hair at the front or just wear it as is, without a hat or headband, I would think you'd need to be at least 21.5 - 22" or larger circumference. Hair is great and has not tangled- really incredible given the length. I've braided it and brushed it a couple of times. it's been laying in a storage box but it hasn't tangled at all while I've been taking pictures of it and moving it about. Very nice synthetic hair fibers that look realistic. I bought it online but I've bought so many hair pieces in the last few years that all I know is it was from fall of 2023, but I don't remember where I purchased it. I do know I am the first owner, it was purchased new. it has never been washed or heat styled.
