1) Can we get Hair Straightening / Smoothening done on our Hair for better look? I am male.

2) Also can females get this done for their Hair?

3) Also it’s permanent hair straightening until new hair comes.
Straightening creams are applied and hair type/structure is changed. Still it’s allowed?

4) My concern is changing the natural hair type/structure allowed?

1) Yes.

2) However, it is not permissible for a woman to show her hair to a non-mahram man at all.

3) If these creams form a layer on the hair, then the hair must be separated and the scalp must be wiped for ablution. As for washing, it does not harm, because washing the hair is not obligatory, but rather the water must be delivered to the scalp.

4) No problem
