I gave this hair one star because I have not used it. I refuse to get it installed. So, I can't really speak to how it holds up and reacts to heat, etc. I gave it another star because the delivery was very prompt. As for the hair itself, I will be returning it. I am just waiting on the seller to respond. The hair sent to me was the Sensual Hair with the purple label. I stayed away from buying that hair in the first place due to poor reviews. If you notice, this item page does not show any packaging for the hair. I was under the impression that it was indian remy bundled hair (perhaps my fault for assuming)...well it is not. Straight out the package I can tell it is a rat's nest waiting to happen. My I just had a bad experience with Model Model hair (which used to be my go to, but after two bad batches and a shedding tangling mess, I swore them off.)At least with Model Model it fooled my out of the package, it felt smooth and shiny and soft for two weeks, before it cut the monkey loose on me. This hair is not even that. It is dull, has jagged edges, short inch-long shaggy hair across the entire weft. It's not even pretending to be something it's not. Very low quality hair that is plastic-y and not even close to indian remy...or mixed blend quality yaki. I have been buying from Amazon relentlessly and this in my first return and my first review. I just believe that if you make an investment to look good (whatever that is for you) you should be given the facts upfront to help you make an informed decision. I truly feel the seller didn't show the product packaging because they knew that product has mixed reviews. Now I will have to wait on my refund and go buy more hair elsewhere...so I can get it together.com before I leave for my trip. Thanks Sundance Import.Sincerely,Not a Happy Camper~
