Caffeine extract is a powerful ingredient for scalp detox and hair growth. It stimulates circulation, increasing blood flow to the scalp, which helps flush out toxins and nourish hair follicles. As a natural DHT blocker, caffeine prevents follicle miniaturization, a key factor in hair thinning and loss. Its antioxidant properties further protect the scalp from oxidative stress, reducing irritation and buildup that can hinder healthy hair growth. Additionally, caffeine extends the anagen (growth) phase of hair follicles, promoting thicker, fuller strands. It also enhances keratin production, strengthening hair structure while reducing excessive shedding. When applied topically, caffeine can penetrate the scalp and energize the roots, helping to maintain a healthier scalp environment.
