Hello all self-taught medical wunderkinds,
Can you please tell me what the name of this phenomenon is, when sweat causes what looks like silvery dust in the hair / on skin?
I’ve tried googling it - to find out how / why it arises - and all I get is advertisements for running clothes and information about using Botox to stop sweating.
As this is not strictly a thyroid post - I don’t think - I can delete it later.
The dust could result from a product build-up on your scalp - such accumulation happens when the styling products are not washed off clean even after what you presumed was thorough shampooing and conditioning. The build-up may include the residues of hair cleansers, as well!
Good point
Mainly salt, potassium, calcium and magnesium plus some trace minerals. thoughtco.com/chemical-comp...
What's interesting in our dry heat in Arizona (or other desert areas) sweat can evaporate so fast you may never feel "wet" or sweaty but you'll have a coating of minerals on your skin.

So do you have to drink a lot? Of water.
Arizona is beautiful in so many ways.
I found myself getting more summer colds in the U.S. than the U.K., because of the air conditioning systems everywhere, was my theory. Do you find that?
Yes - we especially tell visitors to drink a lot of water because when they feel thirsty they're already dehydrated. We keep humidifiers in our home — air conditioning does remove moisture from the air. A lot of homes use "swamp coolers" that run air through water soaked media for evaporative cooling, I much prefer that type but requires a lot of maintenance. Over time you acclimate. Arizona does age your skin unless you live like a hothouse flower.
I think it’s possibly salts too. I used to do a lot of running races and my vest would be saturated with it, like a white powdery stain. I used to drink a lot of water too cos I always felt parched. It stopped once I took thyroid hormones as did the terrible headaches after the race for the rest of the day and I am no longer as thirsty as back then. I could run a lot faster then tho!
Interesting. Thank you. It looks like salt.
