Caffeine

Caffeine is a natural alkaloid found in coffee, cocoa, tea, cola, guarana and mate plants and beverages obtained from them. Coffee and tea are the most consumed drinks which makes caffeine the most used toning and stimulating substance in the world. Caffeine acts as a stimulant not only when taken through food but also when applied to the skin locally: in such case, caffeine is absorbed through the scalp, stimulates blood flow, and favors hair bulb oxygenation.  Well-oxygenated hair bulbs stay healthy and prevent aging and eventual hair loss.
