It doesn't. Heads do not split, or brains fall out.
What you're referring to is the extra muscle that grows at sexual maturity, which can be from 6 months of age in a staffy, but more commonly from 9 months of age. The muscle on the head is one of the secondary sexual characteristics of the male.
I think this myth comes from the fact that the muscle grows in two bulges either side of the head, causing the appearance of a dent on top of the head. Anyone who stops and thinks for a second will realise that a split head would be a skull fracture, which is not a natural part of growth.
Their heads never split.
when do staffs heads start gettin a splitt at what age about and when do they reach there full height? They don't split. From 6 months of age, or more usually from 9 months, they start to mature sexually. One of their secondary sexual characteristics is to develop lots of muscle on their heads. No splitting of any kind is involved. Full height is by 1 year of age. Full musculature in an unneutered male is by around 18 months of age. Please do neuter your staffies, they're my favourite breed but there are far, far too many of them being bred!!
Why would you think the heads split on a female Staffordshire bull terrier? Does your head split? No their heads do not split unless someone takes an ax to their head.
to bust your head open crack your skull damage your head ...split your wig if you had a wig, it would be split
Most Staffordshire Bull Terriers heads ''split'' at about six months to a year, but every dog is different.
Their heads don't split in the sense of cracking apart or anything like that. (I've heard that myth before. Its not true.) That said, a dog's head will "pop" or mature at various ages. Males tend to pop sooner than females. It will depend on the dog's bloodlines, and how slow- or fast-maturing they are.

no it can make your split ends even worse
I'm afraid there isn't such thing as a head split. When rottweilers are young, their forehead is quite rounded. As the dog starts to mature the head starts to flatten out and widen, the excess skin gives the impression of a line going down the center of the head. Hence the term head split.

Bob ended up getting his head SPLIT open after Richard cracked him upside the head with a baseball bat.
