Market Transformation in Dandruff Control: Recent Developments on Anti-Dandruff Active Ingredients

After the European Union’s ban of zinc pyrithione from cosmetic use, piroctone olamine, climbazole, and salicylic acid have become the most common anti-dandruff active ingredients used in cosmetics today. Other conventional chemistries and less frequently used active ingredients, like hexamidine diisethionate and selenium sulfide, have also seen a recent upward trend. Entirely new technologies, like propanediol caprylate and propanediol undecylenate, are only in their initial stages but are ready to change the industry. The aim of the following study is to holistically characterize these compounds, regarding their chemical data, mode of action, and study results, where available, to shed light on the pros and cons and to take a detailed look at environmental considerations, market situation and regulatory aspects. In addition, many commercially available anti-dandruff consumer products combine multiple active ingredients to address the multifaceted nature of the condition, often targeting both fungal activity and scalp inflammation.
