If you are looking for a hairstyle? Something low maintenance and easy to maintain? Maybe your're looking for a hairstyle that will provide you with fuller and longer hair in appearance. Hym Slay'D tape-ins are the route to go. Once tape-ins are removed they can be washed, add on some new tape adhisive and you are ready to reuse them again. Each bundle consists of 100 grams of hair so there is 40 slices per bundle. I recommend 80-100 slices to complete a full head, however; I would strongly suggest consulting with a professional hairstylist to ensure you have the right quantity for you based on your desired look/results.
