ANSWER:

No problem in this when at home.

What is prohibited is for women to go out wearing their hair in a high bun like the hump of a camel. This is not for imitating the camel but for luring people and seducing them. 

I read somewhere women who put their hair in a high bun are cursed because they imitate a camel is this true? Can they still put there hair in a bun when in private for example when in the shower?
