research Patch testing with hair cosmetic series in E urope: a critical review and recommendation
A standardized patch test for hair cosmetics is needed in Europe to prevent allergies, especially for hairdressers.
research Bioengineering a humanized acne microenvironment model: Proteomics analysis of host responses to Propionibacterium acnes infection in vivo
A new model helps study acne and test treatments.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Role of insulin resistance and diet in acne
Eating high glycemic foods and drinking milk may worsen acne by increasing insulin and IGF-1 levels.
research Pattern of tissue invasion by Propionibacterium acnes in acne vulgaris
The document concludes that advanced methods show the presence of P. acnes in acne lesions but do not prove it causes acne.
research Bacteria Display Differential Growth and Adhesion Characteristics on Human Hair Shafts
Human hair shafts inhibit Gram-positive bacteria growth but not Gram-negative bacteria.
