Love love love!!! My hair is just below shoulder length and a off black with a cool grey undertone, while the clip-ins are a more warm red/brown undertone. Yet it’s only noticeable in direct sunlight. I was worried there would be an obvious difference but you can barely even notice, or tell. I got the classic so the track is a little thick which can be uncomfortable at times so in the future I would try the seamless. I can straighten and curl it with no issues. I will be 100% purchasing again in the future and I recommend Luxy to everyone!
