Alright product [SEP] The product is sturdy and easy to use, it is comfortable to wear for about 30 minutes and then it started to get irritating giving me a headache. It is too short for my hair so I had to keep an inch from the top and a few from the bottom out. I wore it for about an hour and the results were okay but not as defined as I would have liked possibly because my hair is on the thicker side, also it straightened out after about 3 hours with light hairspray in. Before putting one in you have to brush your hair very well, wet it, and then put in a strand, pulling it out hurts a bit but you have to squeeze the top and bottom and pull straight out to minimize pulling hair out. Over all good product but would work best on shorter thinner hair, also maybe keep in as long as possible or dry with hair dryer.
