Snopes on Hair

Thanks for posting the website. It was very interesting to read the different wives' tales and seeing the author's different responses. I was also wondering if cold water rinses really do constrict the blood capillaries to the scalp, and how other members here would respond to that statement.
 
Interesting. Thanks for posting.

Very interesting. I never heard about eating bread crusts to get curly hair although I read somewhere that eating persimmons can make hair more kinky (for those who want it).

This is something that came from a stylist out of N.Y.C. named Marvin previously posted on Hair Tips :

32. Always rinse conditioner out of the hair with the coldest water you can stand, this will close the cuticle layer or the hair. The result is your hair will be shiny, and it will stimulate blood circulation.

Here is a previous response to the above:

I'm not so sure about the cold water to stimulate the blood tip. Cold water would constrict the vessels to the scalp.... just as cold air constrict vessels all over your body. Warm air causes them to dialate... so logically, warmer water would increase blood flow... I should think.

i agree with you! just what i thought when i read it.

Yes, what you are saying about dialation and constriction is true but, you have to also remember there is another factor. Which is, when you get chilled you have a tendency to shiver and tense up. Shivering is the body's way of trying to generate heat, in that the cold water rinse is temporary, the shivering causes the body to generate some extra heat(=dialation). When cold water is thrown on you, your body has a tendency to tense up (= adrenaline=increase heart beat=increase circulation).

There are a number of different hydrotherapy treatment that are base on a premise that is similar. They call it hot and cold therapy. There is also a hot and cold stone massage therapy as well to name a few.

This is my K.I.S.S. (Keep it simple sweetie) version.

The first stage of hypothermia is shivering of the body. Shivering is the body's natural reaction to cold. It produces heat.
The nerves carry impulses felt at the skin deeper into the body, where they are instrumental in stimulating the immune system, influencing the production of stress hormones, invigorating the circulation and digestion, encouraging blood flow, and lessening pain sensitivity.

HTH.

This is the quote taken from "Snopes on Hair" that your referring to probably take from Kingsley, Philip. "The Truth About Hair."
[London] Sunday Times. 20 October 2002 (Features, p. 32). (per "Snopes" source section.) I think this particular statement (Kingley's) was previously post on LHCF.(?):

Rinse just shampooed hair with cold water to make it shine.

Cold rinses don't make hair any more shiny than lukewarm or hot ones do, so why put yourself through the suffering? Besides, cold rinses have a negative effect on hair — they constrict blood capillaries in the scalp (tiny blood vessels that deliver nutrients and pick up waste products in return). If the capillaries are to do their job properly, they need to be allowed to operate in a non-constricted state.

I have a question also, based on cold water rinses. I get the impression that opening and closing the hair shaft is temporary when it come to to different water temperatures thus the ideal that cold water closes the cuticle is temporary. Help me out here ya'll. This makes sense ...what I'm I missing here? Or I'm I missing anything? What is the logic here?
