In the Hadith is mentioned severe punishment and curses for women with camel humps on their heads.

Answer

The 'humps' on women's heads refer to such hair styles in which the hair is gathered on the head like a camel's hump. These are kuffaar hair styles. The Hadith brings within its purview all the kuffaar hairstyles which many Muslim women adopt, especially gathering the hair high on the head like a 'camel's hump'. They are constantly under the curse of Allah Ta'ala.
