Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I can understand your concern for hair loss. It may be telogen effluvium. Consult the dermatologist for the perfect diagnosis and proper treatment. There may be many causes, like anxiety, anemia, vitamin deficiency, drugs, internal diseases like thyroid dysfunction, etc. Warm temperature is not the cause. You may take Biotin. Vitamin and iron supplements may be taken. Cap. vitamin E improves the condition. Apply mild steroid lotion on the scalp at night. Mild herbal shampoo and almond oil may be considered for routine care of hairs. Avid anxiety and have positive attitude. Hope I have answered your query. Let me know if I can assist you further.
