Regulation of mammalian hair growth

Abstract

The present invention relates to a topical skin care composition containing a safe and effective amount of a skin care active comprising agmatine, and its salt; a safe and effective amount of a first additional skin care active selected from the group consisting of BHT or BHA, hexamidine, cetyl pyridinium chloride, green tea catechins, phytosterols, ursolic acid, compounds derived from plant extracts, their salts and derivatives; and a dermatologically acceptable carrier for the agmatine composition. The present invention also relates to methods of using such agmatine compositions to regulate hair growth and the condition of mammalian skin. Said methods generally comprise the step of topically applying the composition to the skin of a mammal needing such treatment, a safe and effective amount of such compositions.

Description

TECHNICAL FIELD The present invention relates to topical compositions containing a combination of skin care actives, particularly agmatine and its salts, in combination with other skin care actives such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), cetyl pyridinium chloride, hexamidine, phytosterols, compounds derived from plant extracts, green tea catechin compounds, ursolic acid, and free fatty acids. Such compositions are useful for regulating the condition of keratinous tissue, including, but not limited to, regulating mammalian hair growth, preferably inhibiting and / or retarding hair growth and / or reducing shaving frequency. BACKGROUND OF INVENTION As is well-known in the art, normal hair growth occurs by a cycle of activity which involves alternating periods of growth and rest. This cycle is often divided into three main stages which are known as anagen, catagen, and telogen. Anagen is the growth phase of the cycle and may be characterized by penetrat...

Problems solved by technology

Wherein hair growth ceases, most of the hair follicles reside in telogen and anagen is not engaged, thus causing the onset of full or partial baldness.

However, that function has been lost in humans, in whom, hair is kept or removed from various parts of the body, essentially for cosmetic reasons.

However, such conventional procedures frequently have drawbacks associated with them.

Shaving, for instance, may cause nicks, cuts, rash and irritation and often leaves an undesirable stubble.

Electrolysis and laser hair removal can keep a treated area free of hair for prolonged periods of time, but can be either expensive, painful, and / or sometimes leave scarring.

Waxing and plucking are painful and are poor options for shorter hair.

Anti-androgens, used to treat female hirsutism, can have unpleasant physical side effects as well as possible birth defect implications.

Depilatory devices can be painful to use and are not well-suited for many areas of the body including underarms and face.

Finally, depilatory creams, although effective, are messy to apply and typically are not recommended for frequent use due to their high irritancy potential.
