The JHMA, Japan HeadTherapy Master Association, performed a scalp and hair condition investigation and awareness survey, and the results of these were published by japan.internet.com.
59 men with thinning hair and 58 men without thinning hair were selected by some means for a professional examination of their scalp and hair condition, and also to answer some questions regarding hair care.
Despite my headline, it would be rash, of course, to simply conclude that since people with thinning hair spend longer on average per day on a computer, it is the computer use that is making them that way. It could just as easily be more stress from a longer work day, worse eating habits due to a long work day, snacking in front of the computer, missing out on sleep, or a hundred and one other possible causes that one could come up with.
Furthermore, I didn’t know that massaging conditioner all the way in was bad! I’ll have to fix that from tonight
First of all, the hardness (lack of suppleness or moisture?) of the scalps of the men under investigation was measured by professionals from the JHMA, and the results presented split by balding and not balding men.
Hardness of scalp
Not thinning hair
Very hard scalp 25% 0% Hard scalp 34% 31% Normal scalp 14% 27% Soft scalp 20% 33% Very soft scalp 7% 9%
Q1: How long on average do you spend per day in front of a computer? (Sample size=117)
Not thinning hair
12 hours or more 44% 31% 7 to 11 hours 27% 22% 4 to 7 hours 20% 31% Less than 4 hours 8% 16%
Q2: How long on average do you spend between first applying shampoo until rinsing it off? (Sample size=59, thinning hair)
Less than two minutes 27% Two to three minutes 19% Three to four minutes 37% More than four minutes 17%
The shorter the time the better, as shampoo may dry out the hair and scalp.
Q3: How often do you massage conditioner, treatment down to your scalp? (Sample size=59, thinning hair)
Usually do it 36% Sometimes do it 13% Don’t do it much 24% Don’t do it at all 27%
The less often the better, as conditioner or treatment may damage the scalp.
