Fringe - All About Hair

This blog explores topics in 'Trichology' (the orthodox sciences of human hair). We welcome you either as an interested visitor or a prospective student seeking to study trichology to share your comments and experience. As the archives continue to accumulate, probably at some point they will become a useful reference for all. This hair loss forum may help you to grow hair too!


Hair growth‐promotion effects of different alternating current parameter settings are mediated by the activation of Wnt/β‐catenin and MAPK pathway

Electrical stimulation is being used in variable skin therapeutic conditions. There have been clinical studies demonstrating the positive effect of electrical stimuli on hair regrowth. However, the underlying exact mechanism and optimal parameter settings are not clarified yet. To investigate the effects of different parameter settings of electrical stimuli on hair growth by examining changes in human dermal papilla cells (hDPCs) in vitro and by observing molecular changes in animal tissue. In vitro, cultured hDPCs were electrically stimulated with different parameter settings at alternating current (AC). Cell proliferation was measured by MTT assay. The Ki67 expression was measured by immunofluorescence. Hair growth‐related gene expressions were measured by RT‐PCR.

Perfect Flame Hair

Trichotillomania

‘Flame hairs' is a trichoscopic feature described as hair residue from pulling anagen hairs in trichotillomania. However, a recent study showed that flame hair is not specific for trichotillomania. The flame hair is a type of broken hair which can be seen in a variety of hair disorders such as alopecia areata, acute chemotherapy- and radiotherapy-induced alopecias and traction alopecias.

About Me

As a Dermatologist and Informatician my research mainly involves application of bioinformatics techniques and tools in dermatological conditions. However my research interests are varied and I have publications in areas ranging from artificial intelligence, sequence analysis, systems biology, ontology development, microarray analysis, immunology, computational biology and clinical dermatology. I am also interested in eHealth, Health Informatics and Health Policy.
