Question: Is it permissible for a male to act as a personal trainer for a woman or to be a makeup artist for a woman?
Answer:
In the Name of Allah, the Most Merciful and Compassionate,
It is not permissible for a male to be a personal trainer for a woman if doing so entails his touching her or being alone with her in a private room such that a third party could not enter unannounced. [Ibn ‘Abidin, Radd al-Muhtar; Ala’ al-Din Abidin, al-Hadiyya al-‘Ala’iyya]
Likewise, it is not permissible for a man to be a makeup artist for women for the same two aforementioned reasons. Furthermore, applying makeup for the woman could entail assisting her in provocative displays of beauty which the Qur’an prohibits. [Ibid.]
The exception to the above is if the man is an unmarriageable relative of the woman and her makeup is only meant for a display to her husband.
I hope this helps,
Allah knows best.
