Dyeing the hair – is it permissible to wipe over dyed hair in wudoo’?
Question

                I have check this topics and you have answered my question but i was looking for more information.  My question if sisters put nail polish and if they have to do wadoo they have to remove and do wahoo but what about the hair dye can we do wadoo with hair dye.
Praise be to Allah.It seems – and Allaah knows best –that what 
    is put on the hair or used to make the hair stick together, such as henna and the like, does not affect wudoo’, rather it is sufficient to wipe 
    over it. 
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy 
    on him) said: 
If a woman plasters her hair with henna or 
    something similar, she may wipe over it, there is no need remove the substance in question, because it was proven that the Prophet  (peace and 
    blessings of Allaah be upon him) used to apply something to make his hair stick together when in ihraam.  
See al-Sharh al-Mumti’ by Shaykh Ibn 
    ‘Uthaymeen, 1/196 
What is put on the head and makes the hair stick together becomes part of it, which indicates 
    that there is some lenience with regard to purification of the head. 
 And Allaah knows best.
