Abstract

Claims (40)

1. A hair tool, comprising:

a handle portion; and

a plurality of bristles operatively connected to the handle portion, at least one of the plurality of bristles having a ball-shaped distal tip, the ball-shaped distal tip containing at least one therapeutic agent additive;

wherein the at least one therapeutic agent additive includes CBD or hemp seed oil;

wherein the ball-shaped distal tip is formed from a plastic or polymeric material and contains an absorbent material configured to retain the at least one therapeutic agent additive;

wherein the at least one therapeutic agent additive is mixed with the plastic or polymeric material prior to forming the ball-shaped distal tip; and

wherein the therapeutic agent is contained only in the ball-shaped distal tip and not a remainder of the plurality of bristles.

2. The hair tool of claim 1 , wherein:

the ball-shaped distal tip of the plurality of bristles are impregnated, infused or saturated with the at least one therapeutic agent additive.

3. The hair tool of claim 2 , wherein:

the plurality of bristles are porous.

4. The hair tool of claim 1 , further comprising:

a head portion connected to the handle portion;

wherein the bristles extend from the head portion; and

wherein the hair tool takes the form of a grooming brush.

5. The hair tool of claim 4 , wherein:

the head portion includes a cushion;

wherein the bristles are connected to the cushion; and

wherein the cushion contains the at least one therapeutic agent additive.

6. The hair tool of claim 1 , wherein:

the hair tool takes the form of a grooming comb.

7. The hair tool of claim 1 , wherein:

the ball-shaped distal tip has a micro-porous structure configured to retain the at least one therapeutic agent additive when contacted therewith.

8. A method of manufacturing a hair tool, comprising the steps of:

via additive manufacturing, forming a handle of the hair tool from a first material; and

via additive manufacturing, forming a plurality of bristles of the hair tool from a second material, the second material containing a therapeutic agent additive not present in the first material;

wherein the plurality of bristles are operatively connected to the handle;

wherein the at least one therapeutic agent additive includes CBD or hemp seed oil;

wherein the bristles are formed with a ball-shaped distal tip, the ball-shaped distal tip including an absorbent material configured to retain the therapeutic agent additive.

9. The method according to claim 8 , further comprising the step of:

changing from the first material to the second material as an inline part of the additive manufacturing process.

10. A method of manufacturing a hair tool, comprising the steps of:

via additive manufacturing, forming a handle portion and a plurality of bristles operatively connected to the handle; and

at least one of impregnating, infusing or saturating the plurality of bristles with at least one therapeutic agent additive;

wherein the at least one therapeutic agent additive is at least one of CBD or hemp seed oil;

wherein the bristles are formed with a ball-shaped distal tip via dipping or molding, the ball-shaped distal tip containing an absorbent material configured to retain the at least one therapeutic agent additive; and

wherein the at least one therapeutic agent additive is present only within the ball-shaped distal tip and is absent in a remainder of the plurality of bristles.

11. The method according to claim 10 , wherein:

the ball-shaped distal tip is generally hollow and includes a hole; and

wherein the therapeutic agent additive is received within the ball-shaped tip and controllably released through the hole.
