Very Secure [SEP] This is a nice product and maybe it would be best for someone else so I wont write a bad review, but it made my hair dry around the perimeter where I put it. My clean hair started to flake almost immediately ( I do have dry skin which is not the seller's fault). Also, you could see it in the part. Its very secure, though and I don't mind using it over top of a Velcro band. Its a good product.
