Implementations of a cold cap are provided. In some implementations, the cold cap may be worn on the head by cancer patients during chemotherapy treatments to prevent hair loss on their scalp. In some implementations, the cold cap may comprise a central portion, a back portion, a first side portion, a second side portion, a chin strap, and a compression strap. In some implementations, the cold cap is configured to fold around a persons head when being worn. In some implementations, the central portion, back portion, first and second side portions, and compression strap each have an interior compartment therein configured to contain a cold retaining medium. In some implementations, the compression strap may be used to compress the back portion of the cold cap against the scalp of the wearer. In this way, hair loss on the backside of the wearers head may be minimized or prevented.
