Hi All,
I just got asked this question. The full question was 'Does the steam from a hot shower hurt your hair even if you're NOT washing your hair?. The answer is 'yes.' The steam dries out your hair and makes it dull and lifeless. Only use as much hot water as necessary to take a comfortable shower. Too much hot water and steam will be hard on your hair-and don't forget to run the fan to remove the steam.
Best,
John
