Strand-by-strand extensions allow for greater versatility in styling and last for up to 5 and a half months. The cotton used to attach the extension hair provides an ultra strong, flexible barrier, preventing damage to your own hair. This hair extension application technique was designed to be safe for long term wear and easy to maintain. During the time you wear our glueless strand-by-strand hair extensions you should experience practically no shedding. There is no need for ‘top-up’ appointments saving you time and effort.
