I am myself an ardent customer of hamam, even my family.Since I was 8 I am using hamam and till date I have hardly found any skin issues.
I have oily skin and generally such type of skin is prone to rashes and heat boils but then I have never experienced such discomforts and I suppose its because of hamam. Some reasons why I find hamam to be good is.
-Ideal foaming
-no chemical effects on skin.
-best suited soap foe oily skin.
-gives a refreshing feel after use.
-definitely promotes skin health as my father uses it since his middle age.
-get rid of our body odors easily and provides good sustained fragrance.
Thus, I would definitely recommend people to go for hamam without a second thought and particularly those people with oily skin.
