Dying creams

Q: I got to know that using dying creams is permissible if dyes are porous, but their is no indication on dying creams available in the market as to whether they are porous are not. How can I ensure whether my wudhu is valid or not?

Shampoos, soaps, antiperspirants which contain impermissible ingredients

Q: As soap undergoes transformation during its preparation so it is permissible to use any kind of soap in the similar way can you tell me other things which undergo transformation and can be used no matter what sources are used for it? Can any kind of shampoos be used even if they are made from non zabiha animals or pork and can we use any kind of antiperspirants.
