Sorry for low quality of pictures but I dont have an HD camera.

Looking for feedback,

I have a friend of mine who is looking to fill in spots where his hair is thinning as you can see by his pictures I have attached of his hairloss. My feeling is he should just use fill in spray to add more density and maybe style his hair differently to cover up empty spots........but he wants to go the Hair Transplant route to fill in, I have tried to explain to him that, what if he ends up losing more hair ? he will have to keep on going back and then will he have enough donor hair down the road?

Or do you think he should just shave area and go with a partial hairpiece?
