Is permanent hair straightening religiously permissible?

- There is a process called Brazilian blowout. The hair is wettened by a substance consisting of silicon and keratin and then blown dry; the hair remains straight for four or five months.
- I want to have it done to look more beautiful to my husband but I am hesitant thinking that it might prevent ghusl.
- Is it permissible for me to have Brazilian blowout done?

Dear Brother / Sister,

The issue has several dimensions:

1. It is not permissible for a non-mahram man to do it. Accordingly, a woman, you yourself or your husband can do it.

2. A woman cannot show her hair to non-mahram men before or after she has it done.

3. It will not harm wudu and ghusl if no hardness like oil paint or wax occurs on the skin or hair. However, if there is something that prevents water from reaching the skin or hair, neither wudu nor ghusl will be valid. Wudu and ghusl must be performed after being cleaned.

To sum up, permanent hair straightening is permissible if it is not made by a non-mahram man, if the woman does not show her hair to non-mahram men and if there is nothing that prevents water from reaching the bottom of the hair or hair.
