Abstract: The cap is a durable flexible head covering foundation article to be used on the head of a person under an artificial head covering. The body is dome shaped and contains a smooth inner layer to protect the natural hair and hairline and to retain/provide moisture to the natural hair thereby lessening breakage along the hairline and the hair itself that can be caused by artificial head coverings. The body also includes a smooth or textured outer layer with notches above/framing the top of the ears enabling it to conform to the head of the wearer. The body further includes a reinforced rim allowing for lasting or durable stretch memory of the perimeter of the cap. The present invention contains zero to multiple openings allowing for attachment of the artificial head covering to the natural hair of the wearer.
