Our weft (no clips) human hair extensions are another permanent hair extension option. Installation time is dependent on how many wefts are used and the thickness you choose. Gently woven through braided sections of your hair, they are retightened about every six weeks depending on how fast your hair grows. You not only add length and body to your hair, but you will open up a whole new world of hairstyles! Wefts are also enjoyed for their low maintenance and easy casual look. They are ideal for coarse, curly or thick hair.
