What is Caffeine?

Every day, many people depend on their morning cup of tea or coffee to wake up and prepare for a busy day ahead. Before caffeine became a beloved energy-boosting ingredient, it is believed that the benefits of caffeine were first discovered by an Ethiopian goat herder who noticed that the goats appeared more energized when they consumed the berries of the coffee plant. Today, caffeine is enjoyed by millions and is often considered a morning necessity to many people all over the world. In fact, it is suspected that nearly 80% of the world's population consumes a product that contains caffeine in it; however, in North America this number increases to a whopping 90%. Caffeine, commonly known in beverages such as coffee and green tea, is a stimulant of the brain and nervous system, responsible for giving you that more alert sensation, but did you know that caffeine is also a popular ingredient in skincare and hair care as well?

Though Caffeine has long been enjoyed in foods and beverages for its energy-giving properties, you may also see caffeine in your favorite eye cream or skincare product. When applied to the skin topically, caffeine can constrict blood vessels making the skin appear tighter and less puffy. Not only is caffeine a powerful ingredient in skincare, but it stimulant properties make it a highly beneficial ingredient for the scalp and hair.

The Benefits of Caffeine for Hair

Caffeine has been long appreciated for its ability to energize the body and skin, but what you may not know is that caffeine can also be a highly beneficial ingredient in hair care. In fact, there are several studies that go into the benefits of caffeine in haircare and how it is an ingredient that helps many people who are experiencing issues with hair fall or looking to achieve thicker and shinier hair. In this article, you will discover the top 3 benefits of caffeine for hair, and why using hair care products that contain caffeine can be helpful with combatting hair loss, stimulating hair growth, and improving the overall appearance of the hair.

1. Caffeine Prevents Hair Loss

When it comes to preventing hair loss, Caffeine is a unique ingredient because when applied topically, caffeine has been shown to block DHT, which is short for dihydrotestosterone. Dihydrotestosterone is a hormone closely linked to hair receptors on the scalp and often causes hair loss in men. In several studies, caffeine has been shown to block the hormone DHT leading to less hair loss. Just as caffeine is noted to decrease hair loss in men, this incredible ingredient has also been effective in decreasing hair fall in women as well. Additionally, within studies of caffeine for hair, caffeine applied topically has been shown to elongate the hair shaft by stimulating the hair follicle leading to the appearance of longer and fuller hair.

2. Caffeine Stimulates Hair Growth

For many years caffeine has been speculated to stimulate faster hair growth. Though caffeine has been a hair-growth remedy for many years, it has been wildly recognized in recent years and now found in many products targeted towards scalp and hair health, such as in our RKT Scalp Treatment. Caffeine is a powerful ingredient in hair care when applied topically because it has shown to increase blood flow to the scalp. By increasing blood flow to the scalp, caffeine delivers key nutrients to the hair follicles that are necessary for healthy hair growth. Furthermore, because caffeine can shrink blood vessels, caffeine also combats inflamed scalp, thus improving overall scalp health and increasing hair growth.

3. Caffeine Reduces Frizz and Promotes Shiny Hair

Not only is caffeine a great ingredient for targeting hair loss and promoting hair growth, but it is also great for improving the appearance of hair. Caffeine contains flavenoids, a form of antioxidant crucial for promoting hair regeneration. Providing the hair shaft with the essential antioxidants it needs could help it appear less dull, easier to detangle, and increase shine. Caffeine is also great as it does not strip the hair of its natural oils and instead locks in the essential moisture that nourishes it. The benefits of caffeine for hair and overall scalp health are endless!
