Praise be to Allah.
Going to hair salons includes many evil things which must be avoided and to which attention should be drawn. These include:
1-Western haircuts which involve imitating the kuffaar. Whoever imitates a people is one of them.
2-Messing about with the hair and going against the texts of sharee’ah, such as al-qaza’ which means shaving part of the head and leaving part of it; al-namas (plucking) and trimming the eyebrows, which some men do, unfortunately; shaving the beard, which is wrong; and so on.
3-Exposing oneself to the temptation of the so-called “third sex” or homosexuals who come very close to the people sitting in the hairdresser’s chair, or press themselves against them, or do what is called “massage”, which is a great evil and abhorrent action, and a means that leads to the sin of homosexuality, Allaah forbid.
4-Spending money on sin and wasting a lot of time because what the hairdressers do of washing and drying the hair takes too long; they even put make up on men, may Allaah protect us.
And Allaah knows best.
