Capsicum Annuum L is commonly known as Sierpeper. It is a species of the plant genus Capsicum. It is native to southern North America and northern South America. Sierpeper oil is deprived from the distillation of the fruit part of the Capsicum plant.
Sierpeper oil is naturally a very potent stimulant that is good for increasing the blood flow to the scalp. When placed on the scalp it causes a tingling sensation. That tingling feeling is the cayenne triggering increased blood flow from root to tip of every hair follicle, causing increased hair growth.
