Vegamour GRO Hair Serum may help thicken your hair over time by reducing shedding and promoting fuller-looking strands, thanks to plant-based ingredients like mung bean, red clover, and caffeine. Many users report noticeable improvements in hair density after consistent daily use for 3–4 months, and clinical studies support modest gains in thickness. While it’s not a miracle product, and results vary, it’s a clean, vegan alternative to harsher treatments. I’d recommend it if you’re looking for a natural, non-greasy serum and are committed to using it long-term.
