It really depends how much it bothers you. Some people just shave it all off or keep it very short and can move on with their lives. If you're able to put hairloss into perspective then this is probably the best option. I suspect though from the fact you're on this forum that you don't want to have to do this.
From the rather unclear pic, you clearly have significant frontal loss. It doesn't show if you have any loss in the crown though, or the quality of your donor region. If you can put up clearer pics from different angles we will be able to better advise you.
Other than shaving and forgetting, your options are medication (finasteride and minoxidil) which could help you to hold on to the hair you currently have, or at least slow the rate of loss, hair transplantation, and scalp micropigmentation.
