[Is this working on paint.net?]

I'm not understanding the question very well, but I'll try...

 

It sounds like you're talking about the pink glow on the girl's hair.

To do it, add a new layer (ctrl+shift+n) and open the layer properties window by double-clicking on the layer in the layer window. Set the opacity of the layer to 100 by dragging the slider and click OK. Then, set your primary color to pink and use the paintbrush tool to color where you want the effect to appear. Go to "Effects>Blurs>Gaussian Blur" and set the blur amount to a value between 50 and 100. Click OK and you're done!

i know the PSD CS6

my doubt is see him/her face are look like paint and hair too.. how to do it?

You need to edit your post title to not be the extremely vague and ironically unhelpful "please help!".

 

You need to read the rules.
