As of my last update, Lifebuoy primarily focuses on producing antibacterial body washes rather than hair care products. While they may have expanded their product line since then, I can't confirm the existence of a Lifebuoy Hair Shampoo specifically for anti-dandruff purposes. However, many brands offer anti-dandruff shampoos with various active ingredients to combat flakes and soothe the scalp. If you're specifically interested in Lifebuoy's offerings, you might want to check their latest product catalog or website for any updates or new releases.
