Maybe his hair is white now?
Blonde is much easier to maintain than brunette if you have white hair.
And not as dangerous as a darker shade of hair dye.
Blonde is easier to maintain with white hair. You don’t need to pre-bleach. All I use is a squirt on Roux Fanciful, in the shade called Sweet Cream, after shampooing and it changes my white hair to a soft blonde...and no harsh peroxide needed. Bet Donald does something similar.
