What kind of rash is this?

Mercadies • Mother of 2 wonderful kids!

On Monday we shaved his head like we always do ever 2-3 weeks and gave him a bath, we haven’t used anything different, he has never broke out in a rash any other time we shaved his head or that but this time this happened, he’s not itching it or anything but when you touch it you can feel the bumpiness from it and it’s gotten a little more red then Monday.
