Background: Alopecia is a common concern in general population. Conditions like alopecia areata and androgenetic alopecia are usually diagnosed clinically and rarely investigated . Alopecia can be cicatricial or non cicatricial . Cicatricial alopecia is characterised by scarring, fibrosis and destruction of hair follicles whereas non cicatricial alopecia is a non scarring alopecia , usually reversible and amenable to treatment. Common causes of non cicatricial alopecia include telogen effluvium, androgenetic alopecia , alopecia areata , trichotillomania , scalp psoriasis and seborrheic dermatitis and syphilitic alopecia. Cicatricial alopecia like Pseudopelade of Brocq , Lichen plano pilaris and Discoid lupus erythematosus can present diagnostic dilemma. Trichoscopy is a term coined for dermoscopic imaging of scalp and hair .Trichoscope is a hand held self illuminating device which assists in visualisation of the surface and subsurface structures ,constitutions and colour outlines of scalp and hair ..1 It also assists in visualising vascular patterns , loops and arborising vessels . Trichoscopy aids in visualizing hair at a working magnifications of 10-fold to 70- fold, ( up to 160 ). It may be performed with a manual dermoscope (×10 magnification) or a videodermoscope (up to ×1,000 magnification). 2 It is quick, easy, novel, efficient, and a non-invasive device, saves time and money to achieve a probable diagnosis and enable treatment to start . It predicts the course of the disease and lessens the need for unnecessary biopsies. 3Depending on hair signs, vascular patterns, pigment patterns and interfollicular patterns, can denote specific disease and aid in making the proper diagnosis. Aim – 1.To decode various patterns of hair and scalp seen on trichoscopy 2. To differentiate between cicatricial and non cicatricial alopecia Material and methods: An observational cross sectional study was conducted on 30 new patients visiting with presenting complaint of hair disorder in dermatology OPD in a clinic in Delhi NCR. Trichoscopic findings of these patients was recorded. Observations & Results: Yellow dots, white dots and black dots, follicular patterns were seen most commonly. Homogenous brown honey comb pattern was seen on scalp. Conclusion: Trichoscopy is a valuable aid to visualize scalp and follicular ostia and aids in diagnosis of scalp disorders.
