Thin hair must be a dominant gene.

A's hair has become a mop. He definitely got mom's thin hair, but also dad's curls. Clearly, thin hair is a dominant gene, since I got it despite my mom having thick hair and my son got it despite his dad having thick hair (hey, hopefully he'll get Grandpa's fullness as he ages?).

His hair seems to have exploded in the past few weeks. Today, it's not so bad, but he got a bath last night so it's manageable. Before his bath, however, what a mess.

We're thinking of taking him for a haircut later today....
