Hair on the back and sides

you don't lose, right?

because, i was with my girlfriend, and she was running her hands through the back and sides of my hair, not the front or top.

i was wearing a hoodie, which i use more as a jacket, and it hasn't been through the wash in a couple of weeks - and she said there were hairs in my hood, either mine or dog hair (i have a dog). i said how many, she said 'loads', but i could only see a couple, but she had brushed some off.

either way, would they be from the back and sides of my hair, or would they just be a general build up of hairs from the past couple of weeks do you think?

..... or dog hair. lol.
