Abstract

Devices and/or methods for treating facial hair are provided in order to soften the feel thereof. The devices and/or methods generally alter the structure of the tips or ends of the hair follicles to enhance their feeling of softness. Some devices and methods employ a high speed impacting principle to split the ends of the hair follicles. Some devices and methods aim to reduce the thickness of hairs near the tips through abrasion. Some devices and/or methods employ both crushing/impacting and abrasion in order to soften the feel of a subject's facial hair.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A personal grooming device, comprising:
an appliance including a rotary drive system;
at least one hair softening head coupled to the appliance via a shaft so as to be rotated by the rotary drive system about an axis substantially parallel to an axis of the shaft, wherein the hair softening head includes a plurality of spaced-apart, radially-extending bristle groups, and wherein tips of the plurality of spaced-apart, radially-extending bristle groups are configured to split the tips of the subject's hair from about 1-4 millimeters from ends of the tips of the subject's hair when rotationally applied to the subject's hair.

2. The grooming device of claim 1 , wherein the tips of the bristle groups are applied at a speed above 30 mph (48 kilometers per hour).

3. The grooming device of claim 1 , further comprising a grooming guard attached to the appliance and positioned adjacent the at least one hair softening head, wherein the grooming guard includes at least one slot arranged generally co-planar with the plurality of spaced-apart, radially-extending bristle groups.

4. The grooming device of claim 1 , wherein bristles of the plurality of spaced-apart, radially-extending bristle groups include a material selected from a group consisting of stainless steel, nylon, nylon silicon-carbide, and aluminum oxide.

5. The grooming device of claim 1 , further comprising a guard attached to the appliance and positioned adjacent the at least one hair softening head, wherein the guard is structurally configured to align the tips of a subject's hair for treatment by the hair softening head.

6. The grooming device of claim 5 , wherein the guard includes at least one slot configured to align the tips of a subject's hair for treatment by the hair softening head.

7. A grooming device, comprising
first and second parallely oriented, counter-rotating treatment heads, wherein the tops of the treatment heads are substantially co-planer; and
a drive system coupled to the first and second rotary heads via at least one shaft, the drive system configured to impart counter-rotational movement to the first and second heads via at least one shaft such that the first and second heads rotate about axes substantially parallel to an axis of the shaft,
wherein tips of radially-extending bristles are configured to split the tips of a subject's hair from about 1-4 millimeters from ends of the tips of the subject's hair when rotationally applied to the subject's hair.

8. The grooming device of claim 7 , wherein each treatment head includes a plurality of spaced-apart bristle groups, each bristle group comprising a plurality of bristles.

9. The grooming device of claim 8 , wherein at least a portion of the tips of the bristles of the first and second treatment heads overlap when rotated by the drive system.

10. The grooming device of claim 7 , wherein the drive system includes first and second electric motors configured to drive the first and second parallely oriented, counter-rotating treatment heads.

11. The grooming device of claim 7 , wherein the drive system includes an electric motor and a transmission configured to drive the first and second parallely oriented, counter-rotating treatment heads.

12. A method for softening a subject's hair with a personal grooming device, the device having a rotary drive system and at least one hair softening head coupled thereto via a shaft so as to be rotated by the rotary drive system about an axis substantially parallel to an axis of the shaft, the at least one hair softening head having at least one contact surface that includes tips of radially-extending bristle groups, the method comprising:
rotating the at least one hair softening head; and
applying the at least one rotating hair softening head against the facial hair of the subject in order for the at least one contact surface to impact the facial hair of the subject such that the tips of the radially-extending bristle groups split the tips of the subject's facial hair from about 1-4 millimeters from ends of the tips of the subject's facial hair.

13. The method of claim 12 , wherein the at least one hair softening head includes two hair softening heads, each having a contact surface, wherein the hair softening heads are parallely arranged such that the contact surfaces overlap and are counter rotated by the rotary drive system, wherein applying the rotating hair softening head further includes causing the hair to enter the overlapping area and to be contacted thereby.

14. The method of claim 12 , wherein rotating the hair softening head further includes rotating the contacting surface above 30 mph (48 kilometers per hour).
