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!


PRP in Alopecia Areata


I have blogged about the probability of PRP being an effective modality for hair loss though its wider indications in cosmetic dermatology is less convincing. A new study has demonstrated that PRP may be useful in Alopecia Areata as well. The study published in BJD compares PRP to intralesional Triamcinolone and placebo and demonstrates superiority of PRP.[1] Though it is pilot study with less power, the Ki-67 an excellent marker to determine the growth fraction of a given cell population was included as a secondary outcome measure.

Objective assessment of alopecia and its response to treatment is very difficult and is not often sensitive enough. Changes in hair mass is influenced by both the density and diameter of hair. A new device called HairCheck can measure and represent hair caliber and hair density together in a single number. Here is a study that demonstrates the use of HairCheck.[2] The authors have named this method cross-section trichometry (CST) a less attractive name than the device itself!

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.
