OK, I accept I was a bit facetious in my reply (though it didn't seem
to bother Dag much); but that was just me reacting to the
ever-increasing number of posts I see asking questions that can be
easily answered by the poster running a search on the relevant terms.
Am I the only person annoyed by this phenomenon?

Not sure if my response was posted earlier (here it is):

Sorry I did not respond to your earlier request for cited reference to the
epileptic triggers during haircutting or scalp stimulation connection. (I
was attending a conference). The J Neurol Neurosurg Psychiatry (either 2001
or 2002?) reference was one that I was referring too. (I do not believe it
is a common occurrence and has only been reported a few times in the
literature). I have seen mention of it in a rather expensive
medical/neurology textbook Epilepsy: a comprehensive textbook by ed. Engel
and ed. Pedley (in one of the three volumes but I can't remember which
one). Also an extremely old book, Clinical Treatise of the Diseases of the
Nervous System by Rosenthal (from 1879), mentioned seizure occurrence while
men were having haircuts and/or beard trims. The link isn't all that
surprising when one considers the dense interconnections between the dentate
gyrus and hippocampal formation (a relatively unstable and "epileptic" prone
region in most limbic/temporal lobe epileptic patients) with the ventral
tier thalamic structures (an area innervated by afferents containing
propioceptive and "touch" signals as they ascend along the neuroaxis before
finally reaching areas 1,2,3 or area 4). The current concept is that
stimulation of the ventral tier or associated regions of the thalamus could
end up eliciting greater stimulation to already electrically labile limbic
regions causing bouts of epileptiform activity to trigger (the typical
connection between these structures is generally in inhibitory and
progressive break down in this inhibitory process can lead to disinhibition
or "excitation").

I have to agree with this person. I mean, talk about a paranoiac.

Hair cuts are meant to be good for hair loss -- the act of shaving
your head is meant to stimulate hair growth. To give an example
(uneless your a eunoch who doesnt need to shave), men who shave every
day have thick beards, while those who dont have slim puffy beards.
This is useful to police when trying to catch Osama Bin laden
operatives. The real fellows have fine and slim beards. The cons have
thick beards......

Moral of the story --- in order to prevent male pattern baldness shave
your hair all the time.

Haircuts can be dangerous if you have a Rhabdomyomatous mesenchymal

It's amazing how many papers you bring up if you type "haircut" in PubMed. I
mean, there's "Salon sink radiculopathy: a case series", showing that you
_can_ get problems from the shapooing.

Viz: Am J Phys Med Rehabil. 1999 Jul-Aug;78(4):381-3.

Salon sink radiculopathy: a case series.

Stitik TP, Nadler SF, Foye PM.

Cervical radiculopathy can be diagnosed on physical examination with the
Spurling test, which narrows neural foramina via neck extension along with
coupled rotation and side-bending. In the presence of cervical
radiculopathy, this test can reproduce radicular symptoms by transmitting
compressive forces to affected nerve roots as they traverse the neural
foramina. Treatment of cervical radiculopathy includes patient education to
avoid obvious postures that exacerbate radicular symptoms and to assume
positions that centralize discomfort. A potentially harmful position to
which many patients are unwittingly subjected at least several times per
year occurs when their hair is being shampooed in a salon sink before a
haircut. This posture causes neck extension and is combined with rotation
and side-bending as the patient's head is being manipulated during the
shampooing. When the stylist then also applies a mild compressive force
while shampooing the patient's hair, hyperextension of the neck is produced.
We present two patients with cervical radiculopathy that was significantly
exacerbated after the patient's hair had been shampooed in a salon sink;
subsequently, these patients required oral administration of steroids. These
cases illustrate that patients with suspected or known cervical
radiculopathy should be forewarned to avoid this otherwise seemingly
innocuous activity.

You are all being way too paranoid. People lose brains cells consistently
and on a daily basis. And whoever posted something about you losing 15 I.Q.
points is rediculous and very untrue. Sure you may lose brain cells getting
a haircut but you can pretty much lose brain cells doing anything. The
danger involved is low, the only way you would have a stroke or other damage
would be if you had a medical problem already and you must be very careful
with what you do. In such a case you would probably isolate yourself to your
house.

As for the person who had a headache after a haircut, this could have been
attributed to multiple factors. Hair salons are full of chemicals and other
pollutants that can cause distress for those who are quite sensitive (myself
being one of them). However if you were on the verge of head ache, it
doesn't take much for a bit of rattling around for it to develop into a
headache. It could even be triggered by a loud sounds or light. And no,
brain cells cannot come back to life and are not produced by your body Once
dead, they are permenantly dead. You start off in life with approximately
one trillion brain cells. Now, however, scientists have found that cells in
the region of the brain responsible for memory and learning are capable of
being regenerated in a laboratory. You really shouldn't worry too much about
killing brain cells unless you frequently smoke, drink, or use other drugs.
