Arginine is an amino acid known most amongst bodybuilders and marathoners. Traditionally taken in supplement form, athletes consume arginine to increase blood flow and oxygen delivery during vigorous exercise (Livestrong). For those who prefer a more organic approach, L-arginine is commonly found in dairy, beef, poultry, fish and nuts.
L-Arginine is Naturally Found in the Skin, May Increase Blood Flow and Hydration
Within the skin and hair, it is no surprise that arginine has been shown to increase blood flow as well. Early research has shown arginine is effective for a skin condition known as atopic dermatitis. In the study, researchers studied the effects of a topical 2.5% arginine hydrochloride ointment for its effects on transepidermal water loss (TEWL), urea content in the stratum corneum, and overall skin hydration. Those with atopic dermatitis who used the ointment for 4 weeks saw an increase in urea content as well as a continual increase in skin hydration (Hautarzt).
In the skin, arginine is also cross-linked with leucine to form collagen (The Antiseptic, 2005). It is plausible that arginine deficiencies may lead to lessened collagen production, or a decrease in the quality of collagen produced.
L-ARGININE IS A NATURAL ROGAINE?!
Within the hair, L-arginine supplements have been found to increase nitric oxide levels, causing a relaxation of the hair follicle that has been called a natural Rogaine (Better Nutrition, 2003). Nitric oxide and minoxidil (the active ingredient in Rogaine) both open potassium channels, and is therefore believed to be the reason why L-arginine is associated with hair growth.
