Keeping an easily wet scalp dry and fresh

On humid and rainy summer days, hair easily becomes oily and wet. This wets the scalp as well, leading to excessive hair loss, skin irritation, and dandruff. Therefore, keeping the scalp dry and fresh is very important. I use a hairdryer frequently; using it for just a few tens of seconds helps maintain a healthy condition. I recommend getting close to using a hairdryer this summer.
