Hello and welcome to healthcaremagic. I would keep a possibility of telogen effluvium. Telogen is the resting phase of hair cycle. Hair can prematurely enter from growth phase(Anagen) to resting phase(telogen) therefore resulting in shorter length and increased shedding. After a major stressing event like medical/surgical illness OR post-partum OR weight loss (in your case), scalp hair is prematurely pushed into resting phase (Telogen) from the growth phase (Anaphase). This phase usually starts in the third or fourth month after a major stressor and ends by six months if the stressor is removed. There are certain well known causes of Telogen effluvium: --Deficient Iron Stores --Hypothyroidism or hyperthyroidism --Post partum(after delivery) --Post Surgical or following a Medical illness (typhoid, malaria, dengue etc) --Weight loss/ Dieting etc. I would advice that you get a few lab test done e.g Complete Hemogram, Serum Ferritin levels, Thyroid function tests. In my practice I usually ask my patients of Chronic Telogen Effluvium to take an oral Iron Supplement along with a Biotin supplement for 4-6 months together. However they need to be taken for at least 4-6 months at a stretch. The action is slow, therefore don t expect immediate results. It is advisable to take them for a good 1-2 months to judge whether they are going to be effective Or not. regards
