Let’s about the benefits of coffee in hair growth. Arabica coffee has concentrated amount of caffeine, and coffee has been shown to stimulate hair follicles to grow. It also contains antioxidants, which protect the follicles from damage and help them grow thicker and faster.
Drinking coffee promotes hair growth
Every time you drink coffee your body absorbs about 2 milligrams of caffeine. This might not seem like much, but it's enough to have an effect on your hair growth over time. Studies have found that those who drank at least five cups each day had a significantly higher rate of hair growth than those who did not consume any coffee at all.
Applying coffee topically restores hair growth
It is normal for hair to thin out over time, affecting both males and females. To stop this from affecting you we recommend that you use coffee topically on your scalp to promote new growth. DHT is often to blame for male baldness. But it can also cause hair loss in women who have naturally very high levels of DHT.
Exposure to the wrong kind of shampoo can be very detrimental to your hair. This is because it can damage your follicles and lead to baldness. But interestingly enough, several studies have shown that caffeine can stop hair loss and stimulate hair growth.
One study in 2007 found that caffeine has the effect of blocking the effects of DHT on male hair follicles. This can have a slightly positive effect by stimulating hair root elongation which results in longer, wider hair roots. It also prolongs anagen duration, which is the stage where hair growth takes place. See - Effect of caffeine and testosterone on the proliferation of human hair follicles in vitro

The study also looked at the effects of caffeine on female hair follicles and was found to promote hair growth.
Caffeine is a stimulant and stimulates hair follicles, which might make your hair grow faster & stronger. This should give you fuller, thicker looking hair.
