Greetings. You seem to be having diffuse hair fall and thinning. This could be because of recent physical / emotional insults or stresses and may be manifesting now - including possible damage due to a strong hair cosmetic/or straightening procedure. Also do you have any family history of alopecia.? You'll need hair care lotions- those with vasodilator properties. Eat fruits and veggies in good quantity as a part of your regular diet. See a qualified dermatologist near you. (Caution: do not be lured by unrealistic claims and offers made by quacks who claim to be specialists in trichology n cosmetic sciences or even saloons. Make sure u are treated by a qualified dermatologist). Warm regards, Dr Govind Suresh Mittal, Bengaluru.
