Background: Cistanche tubulosa (CT) and Laminaria japonica (LJ) have been reported to have anti-oxidative, anti-coagulant, anti-cancer and anti-inflammatory properties. They are expected to be a promising candidat for promoting hair growth and treating dandruff and scalp inflammation as a consequence. Objectives: We investigated the efficacy of CM and LJextracts in promoting hair health in patients with mild to moderate patterned hair loss. Methods: Using phototrichogram, we compared the density and diameter of patients receiving placebo or CM and LJ extracts at baseline, 8 and 16 weeks. In order to determine the efficacy of treatment on dandruff and scalp inflammation, investigator``s assessment score and patient``s subjective score are also performed. Results: Using phototrichogram, we compared the density and diameter of patients receiving placebo or CM and LJ extracts at baseline, 8 and 16 weeks. In order to determine the efficacy of treatment on dandruff and scalp inflammation, investigator``s assessment score and patient``s subjective score are also performed. Conclusion: We conclude that CM and LJ extracts are promising substances that promote health of the scalp and hair.
