Hi. The photo attached is not clear. You may be suffering from early onset diffuse androgenetic alopecia. Does your father or brother or maternal uncles have balding? This could genetically predispose you to balding. 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. Folligain lotion could help on regular use. Hope this helps. Let me know if you need any further assistance in this regard. Warm regards.
