Update: husband took the plunge!
He read every single one of your comments and shaved his head the literal next day, but didn’t want me to post until he had some respectable facial hair to back it up. Thank you all so much for the encouragement and kindness, he and I LOVE it and are so grateful that this validating community exists! Also for those who asked about where we live - rural Northern Utah, and we definitely know we are disproportionately lucky.
