Lemon, a popular Ayurvedic remedy, has an uplifting, delightful aroma that leaves the mind feeling clean and refreshed. Rich in vitamin C, it is detoxifying, astringent, antiseptic, disinfectant, anti-infection, anti-fungal, carminative and stimulating. The citric acid in its juice helps restore the normal pH balance of the scalp, which in turn, helps in controlling dandruff and cleansed the hair and scalp of buildup and hard water buildup.
