An example adjustable brush may include a brush head and a handle extending from the brush head. The brush head may include a first plurality of teeth extending along a rotation axis and a second plurality of teeth extending along the rotation axis. The second plurality of teeth may be rotatable independently of the first plurality of teeth about the rotation axis.

A wind comb capable of adjusting the direction of wind includes a housing, multiple first teeth, multiple second teeth, a baffle, and a driving unit. The housing defines a first receiving cavity. The first tooth and the second tooth define a first and a second wind channel respectively, which are communicating with the first receiving cavity. A direction of wind blowing from the first wind channel is different from that of the wind blowing form the second wind channel. The baffle defines multiple first and second vents. Each first vent is communicating with a first wind channel, each second vent is communicating with a second exhaust. The driving unit is used to drive the baffle to cause the first vent to communicate with or isolate from the first wind channel, and to cause the second vent to communicate with or isolate from the second wind channel.

The combination hair band and comb assists people with activities of daily living (ADLs). The combination hair band and comb includes an elongate fabric hair band having a series of small internal combs that assist the user in combing/brushing their hair. A first end of the band is attached to one end of a spring clip, and the opposite second end of the band passes through a hole at the other end of the spring clip. In use, the hair band is tightened by pulling the distal end of the band through the hole in the spring clip. The spring clip is then fastened to maintain the band in the desired position. The internal plastic combs extend through an internal slit in the band and comb the hair as the band is pulled rearward through the user's hair, by the user grasping and pulling the distal end of the band.

An interesting healthcare comb having a significant effect for cleaning dandruff, grease, and impurities may include a comb handle and a comb base that may be mounted on one side of the comb base. A cavity may be formed inside the comb base, a seat plate may be arranged at the lower end of the comb base, and a top plate may be arranged at a top end of the comb base. A plurality of comb teeth may be arranged at one end of the seat plate away from the top plate, and provided with through holes along axial directions thereof. Openings corresponding to the through holes may be formed in the seat plate. A pressing plate may be arranged in the cavity, and ejector pins may be arranged on the pressing plate and penetrate through the openings to extend into the through holes of the comb teeth.

A hair cutter has a base comb with a plurality of base teeth and a supporting comb spaced from said base comb having a plurality of elongated supporting teeth extending to a lesser extent than the base teeth. A cutter blade, which may be adjustable, is secured on the supporting comb side of the base comb in spaced relationship with respect to the base comb with a cutting edge extending in the first direction to a greater extent than the supporting teeth, but to a lesser extent than the base teeth. The hair cutter is structured to have the base teeth and support teeth engaging a portion of the body with progressive movement of the hair cutter serving to effect cutting of the hair to the desired length. The cutter blade may be caused to vibrate by a suitable vibrating motor energized by a battery.

A hair comb structure contains: a first combing element and a second combing element. The first combing element has a first flat sheet, a grip, a slidable rail, a positioning portion extending adjacent to the grip, and multiple first spaced columns. The second combing element has a second flat sheet, and the second flat sheet has a root, a slidable protrusion, and a push button. The push button has a guiding portion, and the guiding portion has a first dent and a second dent which are configured to engage with the positioning portion so that the second combing element slides relative to the first combing element. The positioning portion is moved between the first dent and the second dent so as to adjust a distance between any two adjacent first spaced columns and a distance between any two adjacent second spaced columns of multiple second spaced columns.
