1. Coffee prevents hair loss: The common cause of a male?s hair loss is derived from the effects of the male hormone dihydrotestosterone (DHT). DHT affects hair follicles and slowly creates baldness. When you apply caffeine, though, DHT is suppressed. Then caffeine stimulates hair roots so that hair follicles in an anagen growth phase are motivated to grow stronger, increasing their stamina and endurance. 2. Stimulate hair growth: Caffeine is rich in antioxidants that block possible cause of cell damage and reduces transepidermal water loss (TDWL or TWL) and stimulate healthy cell production. 3. Coffee in hair makes hair more manageable: The nutrient properties of caffeine strengthen hair shafts and thus add extra shine. 4. Coffee for hair growth to improve hair structure: It?s no secret that regular use of caffeine strengthens hair follicles and its related cell structures so hair becomes softer. 5. Caffeine Stimulates Hair Matrix Keratinocyte Proliferation: The hair matrix, where the hair shaft is produced, is a critical part of hair follicle anatomy. This hair matrix produces keratin, the major protein component of hair. Different clinical studies have shown that caffeine stimulates the proliferation of keratinocytes.
