A frechet device is a silicone strip with titanium hooks at either end. It has the ability to stretch to 200% of its original size. It comes in 4 sizes (3,4,5,6), according to the width of area to be removed. It should be removed within 30-40 days. The objective of the frechet is to stretch the hair-bearing scalp without causing any deformation of the head. As the hair-bearing scalp stretches, the bald area is loosened and can then be excised and sutured up. The process is a gradual one and the number of procedures required, depends upon the size of the area of bald scalp.
