After 8 years of having his hand in the cookie jar his hair will turn gold. Then after he retires he will wash his gold hair ever day well walking around the penthouse of Trump Tower #3 with a fluffy white towel wrapped around his freshly washed gold hair and he will be thinking - geese if I dug a little deeper in the cookie jar I could have platinum hair. Cheers!
No. By the end of his term, due to his advanced age, he won't have enough hair left to comb over, much less dye orange.
Therefore, at some point during his term, we will all suddenly be blessed with the heavenly vision of his old melon head wearing a vibrant full helmet toupee. It will be sandy brown in color with just a touch of gray at the temples for that oh so distinguished look.
