"Yellow" Lawn problem

This is what it looked like on the 8th of this month,

I was pleased as the seed had germinated well and was growing, the area before was pretty patchy after some heavy scarifying

 

It looks like my frontyard's lawn.
What I actually hate is the yellow colour at the rootes of the grass' leaves.
It looks like those people who dye their hair but once they are grown up you can see the white colour at the rootes of the hair.
I also hate when the grass' leaves are so sparse.
Like those people with a few hair on their head who make their hair grow up to cover their baldness.
And on windy days, all that "hair structure" collapses.

 

Are you having a hair crisis?
