The present invention relates to a brush, comb, or hair appliance having a cage body comprising one or more functional inserts or plugs accommodated within the cage body containing bristles, teeth, or mini posts, such as loop posts and/or hook posts. Such cage-type hair tools may have no electricity or source of power, they may use traditional sources of power, or they may be heated by exposure to hot air, hot surfaces, or other heat sources. The one or more functional inserts within the cage body may be sized to move within the cage, made of a deformable and recoverable material, and/or have a specific shape to force into the cage body and expand to fill or overfill the cage body and may include hair additives, including but not limited to water, air, moisture, steam, liquids, fragrances, gels, mousses, foams, conditioners, keratin, oils, sprays, volumizers, softening agents, and/or powders.
