But not just yet.
In a sweet selfie that Stamos shared Wednesday, the toddler grabs his dad’s mane. Stamos hashtagged it #hairenvy and wrote: “Someday son, someday.”
Many commenters on Instagram made the same joke, mentioning Stamos’ “Full House” character Uncle Jesse’s catchphrase when he didn’t want someone to touch his signature locks — “Not the hair” and the “Watch the hair.”
The kid does appear to be the hair-apparent. So prepare to step aside, John.
