BACKGROUND

This application relates to scalp brushes that remove dead skin cells.

BACKGROUND

Prior Art

Many products have been employed in an attempt to remove dead skin cells from the scalp before becoming dandruff. Shampoo, special chemicals compounds, hair brushes and scalp scrubbers are some examples.

One prior art reference can be made of a pharmaceutical hair device having “hollow teeth” U.S. Pat. No. 3,053,264 filed May 18, 1959 by inventor Alex T. Breton. This and other devices having “hollow teeth” (tubes) might have ends that are sharp enough to cut hair. These tube designs do not protect the user from hair loss due to a sharp or rough surface on the brushing ends of the tubes.

The possibility of cutting hair places the tube design in need of some modification.

SUMMARY

In accordance with one embodiment an aperture for a scalp brush that removes and retains dead skin cells without cutting hair defined by the aperture's diameter and perimeter design.

Advantages

One advantage of an aperture for a scalp brush that does not cut hair is that tubes can be used safely as part of a dead skin cell removing device for the scalp. Another advantage is the aperture contains the dead skin cells and can be used as a tool to measure quantities removed.

DETAILED DESCRIPTION

First Embodiment

FIG. 1

In FIG. 1 (perspective view) the first embodiment of aperture (20) is shown as part of tube (22) made of stainless steel. Tube (22) has an outside diameter of 1.59 mm, an inside diameter of 0.81 mm and a length of 28.6 mm.

The perimeter of aperture (20) at tube brushing end (68) of tube (22) has a contour (84) on the outside edge of the end of the tube wall. This contour is created by rounding off the outer corner of tube brushing end (68) with 320 grit sandpaper.

The sanding process establishes the predetermined point (70) where contour (84) from tube brushing end (68) intersects the outside of the tube wall away from tube brushing end (68).

The sanded contour (84) is buffed to a polished surface. The inside edge of tube brushing end (68) is also polished to remove any rough surfaces and to unsharpen the inside edge of the end of the tube wall. This is done by using a round toothpick dipped in a regular course rubbing compound. This compound can be acquired at most auto body supply stores. The toothpick with compound applied is placed inside of the aperture end of the tube and rotated to polish the inside edge removing any sharpness that can cut hair.

The first embodiment comprising the combination of aperture (20), contour (84) and tube (22) is a scalp brush that can be held between a finger and the thumb.
