I had another picture in mind but I’m a Harry Potter fan, go figure…
I personally didn’t think this was possible until I found some interesting info. Thanks to Hairfinder.com
“Technically, yes they can, although it is less likely. Current accepted theory is that dandruff is caused by a wide variety of things from overproduction of skin cells, sensitivity to yeast, and an overabundance of the fungus malassezia (which occurs in everyone) on the scalp. It is also linked to seborrheic dermatitis and simple dry skin. Depending on the cause in an individual, the fact of being bald usually helps to mitigate many of the conditions that would promote the development of most of these issues.”
“Without hair, the scalp stays drier and is easier to exfoliate and keep from becoming a backup or depository of dry skin cells. With the ability of the bald man to easily cleanse and dry the scalp and to remove any skin cells that may begin to accumulate, there becomes a far lesser chance that dandruff will occur.” – Hairfinder
So basically dandruff is caused by irritation, dry skin, or fungus on the scalp. The presence or lack of hair doesn’t affect this for the most part. Dandruff appears as dry white scales when the skin on the scalp sheds its dead cells. The problem is aggravated because of the presence of hair on the scalp.
