Unilever’s Microbiome Breakthrough Paves Way for Gender-Tailored Scalp Treatments

In a pioneering study published in the British Journal of Dermatology, Unilever scientists have uncovered sex-based differences in the scalp microbiome that could revolutionize how dandruff and other scalp conditions are treated. The findings mark a significant step toward personalized haircare, with potential for gender-specific formulations that address the unique microbial ecosystems of male and female scalps.

The study—titled Dandruff Scalp Microbiome Exhibits Flake Severity and Sex-Related Differences—mapped how the presence of two key bacterial strains correlates with dandruff severity. Researchers found that the abundance and behavior of these microbes vary significantly between men and women, suggesting that a one-size-fits-all approach to scalp care may be scientifically outdated.

Implications for Product Innovation

– Targeted Formulations: Brands could develop gender-specific shampoos and scalp treatments that align with microbial profiles.

– Precision Dandruff Care: Treatments may be tailored not just by flake severity, but by biological sex, improving efficacy.

– Microbiome-Friendly Beauty: The findings reinforce the importance of preserving microbial balance, a growing trend in skincare and haircare.

Unilever, already a leader in microbiome research with over 100 patents and the world’s largest human skin microbiome dataset, is expected to integrate these insights into its Power Brands like Clear, Dove, and Dermalogica.
