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!


The Transient Role for Calcium and Vitamin D During the Developmental Hair Follicle Cycle

The role for 1,25(OH)2D3 and/or calcium in hair follicle (HF) cycling is not clear despite their impact on keratinocyte differentiation. We found that calbindin-D9k null (KO) pups generated from calbindin-D9k KO females fed D deficient low calcium (0.47%) diet (D-/ low Ca) develop transient alopecia. The pups appear phenotypically normal until 13 days of age, after which the hair progressively sheds in a caudocephalic direction resulting in truncal alopecia totalis by 20-23d, with spontaneous recovery by 28d.

Dermatitis artefacta presenting with localized alopecia of right eyebrow and scalp

A Sarin, Shijin A Ummar, Betsy Ambooken, Sonali R Gawai

International Journal of Trichology 2016 8(1):26-28

Dermatitis artefacta (DA) and trichotemnomania are self-inflicted dermatoses often preceded by psychosocial stressful events. A 38-year-old female presented with sudden loss of hair in the right frontal area along with discoloration and edema of skin. On examination, there was complete loss of hair involving the right frontal area and the lateral half of right eyebrow with skin over that area appearing scalded, edematous, bruised, and discolored. After a detailed medical and psychological evaluation, a clinical diagnosis of DA with trichotemnomania was made. A tactful multidisciplinary approach is essential in managing such patients as outright referral to a psychiatrist could be counterproductive.

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.
