Justin Baldoni has been growing out his hair for four years. It has gotten so long that he has kept it in a man bun. Not only is it long enough for that, but it is also long enough to donate.
So the actor went into a salon with his wife and kids and got the big chop so that he could donate his (Jane the) Virgin hair to Locks of Love.
And now he looks just like he did when he was on Jane the Virgin. Is anyone complaining about his shorter hair? I am definitely not.
