CAFFEINE HAIR BENEFITS
Wondering what ingredients make your hair grow longer? Caffeine is the main ingredient you need to look out for if your priority is stimulating your roots, speeding up growth or giving thinning hair a boost. Just as a morning coffee can bring us to life, caffeine has the power to energise follicles, resulting in increased density and growth.

So, is it as easy as simply drinking more cups of coffee each day? Not quite – but there are simple speedy solutions. When it comes to hair growth, caffeine is best applied topically. When hair products are massaged directly into the scalp blood circulation is improved, making it easier for your roots to absorb essential nutrients and minerals.
- Dihydrotestosterone (DHT) is a testosterone-derived hormone that prevents vitamins, proteins and minerals being properly absorbed by hair follicles
- DHT can lead to hair loss
- Caffeine combats DHT, causing cells to produce more ATP – a form of energy that encourages growth – helping you achieve a fuller, healthier-looking hair swish
