Bigen Men’s Speedy Hair Color is an ammonia-free, non-drip cream formula designed for quick and easy gray coverage in just 5 to 10 minutes. Infused with taurine, glycine, and olive oil, it moisturizes hair and reduces damage while leaving no harsh chemical odors. The cream applies directly with the included comb without pre-mixing, and any unused portion can be saved for future touch-ups.
