It's called "beauty-parlor syndrome", though they're also eyeballing neck twisting chiropractors.

"According to experts, when you push a person's head back into a sink his/her neck over-extends. According to neurologists Dr. David Bateman, Cumberland, UK, the neck can be stretched so that it kinks for a long time - as in hair-washing at a salon - the arteries get stretched and can tear if you are unlucky. As the bleeding between layers of tissue continues you can get clots building up, this eventually leads to a stroke."

"Beauty parlour shampooing is generally safe but it may be hazardous for certain people. An individual's threshold for ischaemic symptoms depends on several factors, including speed and duration of movements, intactness of collateral blood flow, extent of atherosclerosis, and presence of congenital hypoplasia or intimal arterial defects"

"Neck injury, when associated with spontaneous tearing of the vertebral or carotid arteries caused by sudden and severe extension of the neck, neck rotation, or pressure on the artery, is a contributing cause of stroke, especially in young adults. This type of stroke is often called "beauty-parlor syndrome," which refers to the practice of extending the neck backwards over a sink for hair-washing in beauty parlors. Neck calisthenics, "bottoms-up" drinking, and improperly performed chiropractic manipulation of the neck can also put strain on the vertebral and carotid arteries, possibly leading to ischemic stroke."
They're debating the fuck out of it, since it's a risk, but they're still figuring out how big a risk

The kink world often plays harder and longer than hairdressers, so if there's a risk for vanilla's, the kink risk is proportionally higher
Age is a factor, a 20year skinny kink.com model with bendy artery's, can hold poses that a 30year old weekend amateur with harder artery's due to age, cholesterol, weight, age, probably shouldn't.

"Signs and Symptoms
Vertigo, the sensation of spinning even whilst a person is still, is the most recognizable and quite often the sole symptom of decreased blood flow in the vertebrobasilar distribution.[citation needed] The vertigo due to VBI rarely is brought on by head turning, which could occlude the ipsilateral vertebral artery and result in decreased blood flow to the brain if the contralateral artery is occluded. When the vertigo is accompanied by double vision (diplopia), graying of vision, and blurred vision, patients often go to the ophthalmologist. If the VBI progresses, there may be weakness of the quadriceps and, to the patient, this is felt as a buckling of the knees. The patient may suddenly become weak at the knee and crumple (often referred to as a “drop attack”). Such a fall can lead to significant head and orthopedic injury, especially in the elderly."
