Seamless clip-ins are similar to weft clip-ins, but instead the hair is attached to an ultra thin silicone base that is very hair-friendly and invinsible. This works great for women with thin hair as the thin invisible weft is “poof-proof,” which is a word we created that means it lays flat. This line of extensions can be installed in minutes and are a great accessory when you want instant length, volume, or want to cover up thinning.
