Wudhu

Q: Will masah of the head be valid when hair spray is used on the hair?

Q: There is a hadith that if one gets up from his sleep, he must not put his hands into a vessel before washing them because one doesn't know where his hands were when he was sleeping. So do my hands become impure after I get up from my sleep? 

Q: When doing masah in wudhu, should masah be done on the full head (no part should be left out) or part of the head? 

Q: If I already have wudhu, will I be rewarded for making another wudhu?

Q: I wasn’t sure if I had passed gas during salah, so as the hadith mentioned (not to stop prayer until a sound is heard or smell is detected) I stopped recitation for a moment and tried to detect a smell. I didnt smell anything and I resumed. Was this ok of me to do?

Q: In the wudhu, wet back side of neck is sunnah or farz?

Q: Through eating camel meat, will the wudu break according to the Hanafi mazhab? 

Q: I am a woman who has severe acne on her scalp. This has been causing me extreme distress, especially with regards to purity and showering. The pimples on my head are infectious and filled with pus. They pop all the time and when they pop they release pus/blood/liquid for usually two-three days (this is called "weeping", common for acne pimples). It is almost impossible to catch a time when there are no "weeping" pimples on my head. The only time I get to wash/shampoo my hair is when it is fardh for me to make ghusl (usually once/twice a month). I am afraid to wash my head otherwise because that would only spread the impurity coming out of the pimples all over my body. However, it is becoming extremely difficult not to wash my hair.

My hair is long and my scalp becomes very oily quickly and it makes me feel disgusted. Not washing it often seems to be worsening my acne, as well as making my head itch like crazy (and itching it just pops more pimples). There doesn't seem to be any effective medical solution for scalp acne, I've tried a couple things but none of them worked. This situation is really stressing me out. Can I just shower whenever I want to even if the pimples on my head are releasing impurity? What do I do about the impurity going all over the rest of my body?

Q: Is the glue used in a plaster waterproof? If I remove the plaster, and after doing wudhu, perform several salaahs, and then find out that the glue is still on my limb, are my salaahs valid or should I repeat them?

Q: Is it mandatory to do wuzu before taking bath (after sex)?
