See a dermatologist: Decrease stress. Eat a healthy balance diet which includes protein. Have thyroid levels and iron stores checked. See a dermatologist for evaluation and work-up. Topical Minoxidil twice a day is the only proven remedy to thicken hair. However, this treatment it is not appropriate for everyone (given the warnings, precautions, and contraindications). See and discuss options with a dermatologist.

Agree w Dr.Somani: Get enough sleep,avoid excess sugar & fat, v carbonated drinks, eat enough protein, exercise regularly. Insure you have adequate Iron (like kale & other dark green leafies), Omega 3 fatty acids (like walnuts),vit.E (fruits & veggies), D & B vitamins, biotin & zinc. Avoid sulfates & formaldehyde in shampoos, over-washing, excessive blow dry heat & curling irons. When needed use quality conditioner.
