Product to Hide Hair Loss After Swimming?

What is a good product to hide hair loss after swimming?

I’m not aware of any products, short of a wig or weave. I suppose shaving your head would hide genetic hair loss pretty well, too.

Many wig makers claim that you can swim with a hairpiece on. If they are tightly woven into your hair (recently done) then they may stay on. I would not dive off a board, but swimming with these hairpieces has to be gently done. Nobody would want their hair to float away when in a swimming pool.
