It Hexamidine diisethionate effective against dandruff?
Hexamidine diisethionate is a poly-valent preservative with a particularly broad anti-microbial spectrum against bacteria, yeasts, and molds. Two special properties led to testing its anti-dandruff efficacy in a clinical study: its cationic character, guaranteeing a good substantivity to hair and scalp, and its efficacy against Malassezia furfur, a fungus considered to be the most common cause of dandruff.
A clinical study was carried out on 32 volunteers, using a shampoo containing 0.1% Hexamidine diisethionate every day for 4 weeks, against a placebo and positive control (zinc pyrithione at 1 %). Evaluations by the users have shown that:
- The anti-dandruff effect is visible after 1 week and increases during the 4 weeks of treatment.
- The obtained efficacy is at least as good as the positive control, and the effect is maintained 2 weeks after ending the treatment for more than 70% of the persons, better than zinc pyrithione.
- The tested shampoo was overall appreciated by more than 70% of the volunteers for its efficacy to improve the state of the scalp: diminishing dandruff, reducing itching, and delaying the time it takes to get greasy again. Quite impressive for a rinse-off product!
