Am i balding?

[123d]

Hi all,
25yr. Have fairly thin hair and hairline has slowly receded at the peaks. Nothing on the top. No family history of baldness. My father has the same hair pattern, but my fathers father (grandfather) is nearly bald.
Not sure if i am going bald or not.
Any potential treatments that can thicken my hair and prevent this from happening?
Your thoughts and advice would be great. thanks
