Description

MEANS FOR IMPROVING THE APPEARANCE OF MAMMALIAN HAIR AND NAILS

TECHNICAL FIELD

The present invention relates to improving the cosmetic appearance of mammalian hair and/or nails, particularly increasing the shine of mammalian hair and decreasing the breakage of mammalian nails. More particularly, the invention relates to improving the appearance of mammalian hair and/or nails by orally administering a dietary supplement comprising a safe and effective amount of a sugar amine to a mammal, preferably a human.

BACKGROUND

Mammalian hair and nails are subject to insults by many extrinsic and intrinsic factors. Extrinsic factors include environmental pollution, wind, heat, low humidity, ultraviolet radiation (e.g., from sun exposure), and the like. Intrinsic factors include chronological aging and other biochemical changes produced by the body. Additionally, diet and nutrition can have a major impact on the appearance of the hair and nails. In today's society, many people's diets are nutrient deficient and/or imbalanced, resulting in less than optimal hair and nail health and appearance. These extrinsic and intrinsic factors, as well as an insufficient diet, can contribute to hair appearance that is lifeless and dull, rather than attractive and shiny, and to unattractive nails that are brittle and break easily.

Thus, many consumers have hair that is not as visually attractive, and in particular not as shiny, as desired. In addition, many consumers have nails that are not as attractive, and in particular broken, brittle, or not as strong as desired. Accordingly, there is a need to provide consumers with a means of achieving a shinier hair appearance and/or stronger, unbroken, more attractive nails.

SUMMARY OF THE INVENTION

The present invention provides consumers with a means of achieving a more attractive, shinier hair appearance and/or stronger, unbroken, more attractive nails. In particular, the invention provides for the use of a dietary supplement by a mammal, preferably a human, for the purpose of increasing the appearance of hair shine and/or increasing the attractiveness of the nails by decreasing brittleness and breakage. The dietary supplement comprises a safe and effective amount of a sugar amine.

In another aspect, the present invention provides a method for informing consumers that oral administration of the dietary supplement can increase the attractiveness of the hair and/or nails. In yet another aspect, the invention is directed to an article of commerce. All documents cited herein are incorporated by reference in their entirety; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention.

DETAILED DESCRIPTION

While the specification concludes with the claims particularly pointing and distinctly claiming the invention, it is believed that the present invention will be better understood from the following description.

AU percentages and ratios used herein are by weight of the total composition and all measurements made are at 25 C, unless otherwise designated.

The term "safe and effective amount" as used herein means an amount of a compound or composition sufficient to significantly induce a positive benefit, preferably a positive appearance benefit of the hair and/or nails, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan. A. USE OF DIETARY SUPPLEMENT FOR THE PURPOSE OF IMPROVING THE

APPEARANCE OF HAIR AND/OR NAILS

According to the present invention, the dietary supplement is suitable for oral consumption and is administered orally. In preferred embodiments, the dietary supplement is in the form of capsules (e.g., those meant to be swallowed or chewed), tablets (e.g., those meant to be swallowed or chewed), powders (e.g., the powder can be added to water, milk, or another liquid), liquids (e.g., either in ready to drink form or suitable for dilution in another beverage), or nutritional foodstuffs. For example, the dietary supplement can be in the form of nutritional bars (e.g., meal or snack bars), cookies, candies (e.g., taffies, caramels, jellies, chocolate melt-aways, chews such as fruit chews, gums), syrups, or beverages (e.g., ready to drink or in the form of concentrates or powders).

As used herein, the term "dietary supplement" is broad enough to include not only single dosage forms, but also multiple dosage forms used in conjunction with one another. For instance, in one embodiment, the dietary supplement is a capsule (e.g., containing both omega fatty acids and glucosamine). In another embodiment, the dietary supplement is two capsules (e.g., one containing omega fatty acids and one containing glucosamine). In yet another embodiment, the dietary supplement comprises a beverage containing glucosamine that is consumed in conjunction with a capsule containing omega fatty acids. As used here, "consumed in conjunction with" or "used in conjunction with" means orally consumed at the same time or at different times.

As used in the present application, the term "improving the appearance of hair and/or nails" includes, but is not limited to, increasing hair shine, luster, and/or radiance; improving and/or increasing nail strength, reducing nail brittleness and/or nail breakage; prevention and/or correction of the functional disorders of the pilo-sebaceous unit of mammals, particularly humans, for instance the treatment of oily and/or hyper-seborrheic scalp, thin hair, hyper-trichosis, and/or alopecia; increasing the density of hair, especially human hair, and/or reducing the heterogeneity of hair diameter and/or improving (e.g., increasing the rate of) the growth of hair and/or nails and/or preventing and/or reducing and/or delaying hair loss; and increasing hair volume.

As used herein, the term "heterogeneity of hair diameter" refers to a significant variation in the hair diameter in a specific region of the scalp; some hair having a physiological diameter in the range of 100 um, and others, in the nearest proximity of those hairs, having a reduced diameter (e.g., thin hair). Thus, by "reducing heterogeneity of the diameter," it is meant increasing the diameter of thin hair. By "increasing the density," it is meant increasing the number of hairs per square centimeter of skin or scalp.

The regimen of consumption can vary according to the form of the dietary supplement. For instance, if the dietary supplement is in the form of a capsule or tablet, it is preferably taken orally with one or more meals daily. For example, the capsule or tablet may be taken daily with breakfast, lunch, and/or dinner. More preferably, there is oral consumption of the capsule or tablet form of dietary supplements of the present invention over an extended period during the subject's lifetime, preferably three times a day for a period of at least about a week, more preferably three times a day for a period of at least about one month, even more preferably three times a day for at least about three months, even more preferably three times a day for at least about six months, and more preferably still three times a day for at least about one year. While benefits are obtainable after various maximum periods of use (e.g., five, ten or twenty years), it is preferred that oral consumption of the capsule or tablet foπn of dietary supplements of the present invention continues throughout the subject's lifetime.

In combination with the oral consumption of the dietary supplements of the present invention, a product suitable for topical application can optionally be applied to the hair and/or nails as part of a combined treatment regimen. In one embodiment, one or more topical products are applied to the hair and/or nails for the purpose of increasing their health and/or attractiveness, in addition to orally consuming the dietary supplement for the same purpose. In another embodiment, a combined treatment regimen is not used; rather, the dietary supplement is orally consumed but topical products are not also used for the purpose of improvement in hair and/or nail appearance (e.g., increasing hair shine and/or decreasing nail breakage and/or brittleness).

The dietary supplement herein comprises: (1) a safe and effective amount of a sugar amine, and (2) optionally, any suitable optional components.
