You may have noticed the thread i made in the new members section, if not im Nick

Basically i've been pretty depressed for quite awhile with my hair, sometimes to the extent where i dont want to go out of the house or see anyone. Well anyways my hair is receding pretty bad at the moment and seems to have gotten even worse in the past 2 1/2 months and i've had my hair cut shorter and shorter over this period to try and deal with it but it seems to make it look even worse due to my face shape etc.
So i though i'd be best shaving, as i had shaved hair along time back and i really liked it, but my dad and eveyone kept saying i have a really white head, so i ended up growing it back and in return feeling very shy about my hair again.
It seems like my dad wants me to keep my hair as long as possible as he said he lost his at around my age, in his twenties (im currently 20) but i find it very hard to tell him its depressing me.
I'll post a couple of pictures below:
This picture is about 2/3 years ago, when my hair seemed to be ok, but still it felt very very fine.

And this one was taken about 2 days ago, when i went out taking car pictures:

As you can see, in this period of time its gone pretty high up my head and it looks even thinner in the mornings when i wake up

.
So i was wondering guys, could you give me abit of help with what to do please?
Do you think my head would look ok shaved or...?
Also how would i be able to sort the white scalp problem if i do go ahead and shave?
Should i grow a goatee or something too?
Sorry for the very long thread, thanks for reading though
