I have heard that Muslim women shouldn't get their hair treated by women who aren't Muslims so that they won't reveal their shame. Is this true? If so, does it simply that a Muslim woman's hair is considered shameful in Islam?
Bismillah
Thank you for your question. There is no problem in a Muslim woman getting her hair treated by other women, whether they are Muslim or not, and there is no issue of shame in a woman's hair or body. For waxing and other types of hair removal treatment, the hair around the private parts of a woman should never be shown to any other women except for medical purposes, hair removal not being a medical purpose.
May you always be successful
