Effect of an Oral Probiotic Formula on Scalp and Facial Skin Condition, Glucose, and Lipid Metabolism

This systematic review reported that probiotics, prebiotics, synbiotics, postbiotics, and dietary supplements may improve hair density and reduce dandruff severity in individuals with scalp disorders, potentially by modifying inflammation, oxidative stress, and microbiota composition; however, variability across studies limits the strength of these conclusions.

This review highlighted significant properties of probiotics that can promote hair growth and reduce dandruff, offering guidance for future research to scale these findings to pilot studies.

This study found that consuming a fermented protein mixture for 60 days may increase hair density in healthy adults, although it did not significantly change other scalp or hair conditions like thickness, pore condition, or blood vessel exposure.

This review assessed dermo-cosmetic treatments using prebiotics, probiotics, synbiotics, and other biotics for acne and scalp disorders, finding potential benefits, especially with multi-strain or synbiotic formulations, although challenges like formulation stability and the need for larger trials persist.

In this study, researchers explored the formation of the skin's epidermal barrier, its interplay with skin microbiota, and the role of skin appendages, suggesting that probiotics might offer promising avenues for treating scalp diseases, particularly those affecting hair loss.
