Among the weird and wacky ideas people have tried over the years to cure baldness, nothing comes close to the suction cap. The idea was simple, create suction on the scalp and you will bring blood to the scalp nourishing the hair follicles and stimulating hair growth.
Fortunately, as many hair transplant patients will testify, transplanted hairs grow perfectly fine on a totally bald scalp proving that a lack of blood supply was never the reason the hair fell out in the first place.
