Do I have hair loss?

Due to hairfall my scalp is visible in my temple area. Rest all is fine. Should i go for fin and min treatment?

Lighting, a short hair cut and straight hair can produce what you are showing. If you had your hair cut to the same length in the past with the same lighting and it was different, then maybe it is hair loss. Before you start a lifetime treatment for hair loss, see a doctor and find out if you have genetic balding first.
