Going to beauty salons

Q: Please can you tell me if this is permissible. My wife never exposes her hair outside the home. Is it permissible for me to send her to a hair salon to beautify her hair for me? It will not be cut or coloured, only styled. And the salon will be one where there are no men.

Hadith question

Q: I heard of a hadeeth, I can't exactly remember but it mentions that in Judgement day, Allah will put the sins of a believers onto a non muslim and that the punishment for the believer would be replaced by a non muslims. Is there any Hadeeth of this sort and if there is, would you tell me what this specifically means, any reliable interpretations of this hadeeth?

Waswasahs

Q: I have been having a problem for very long now, like a year. Its the  problem of waswasa. I get these thoughts of kufr and I can't stop it. I know we are supposed to ignore it but the shaytaan overtakes me. I know there is no god but Allah and this deen truly is the haq but shaytaan gives me waswasa.I have had enough now. I am always depressed. Is there any way to stop this?
