Hi. You may be suffering from early onset androgenetic alopecia. Since your father also has balding, you are genetically predisposed to it. Further environmental factors , pollution, stress, junk food and poor diet could cause you to lose hair further. You'll probably need treatment with hair care lotions or serums - something that has vasodilator properties and improves thickness of hair and reduces hair loss. Have a good balanced nutritious diet. Yes your hair density can be restored if you take timely treatment and care of your hair. Warm regards. Dr Govind Suresh Mittal, Bengaluru
