Lock Him Up! Lock Him Up! Lock Him Up!

Mr. Trump spent more than $70,000 on hairstyling during several years of his run on “The Apprentice,” his reality-TV show.

That, of course, is quite a lot for any one person to spend on having his hair cut, blow-dried or colored. But what is really remarkable about the revelation is that Mr. Trump’s production company deducted his hairstyling expenses from its taxable income, reducing its tax bill.

Tax experts told me that deducting what is ordinarily considered a personal expense is prohibited under almost any circumstances. And they said such a deduction could potentially constitute criminal tax fraud if the cost of the hairstyling was reimbursed by someone else.

Three former NBC executives involved in “The Apprentice” told me that, while they didn’t recall the exact terms of Mr. Trump’s contract, they were very familiar with the way such contracts are typically written. The cost of hair and makeup for a star of Mr. Trump’s stature would generally be covered by the show, and Mr. Trump would have been reimbursed for any of the costs he incurred.

If this can be proven, and if Trump goes down for tax fraud because of it, there is something that will be deliciously ironic about him going to prison for double-dipping on his hair styling.
