I know that it is permissible for a woman to use henna to color her hair, but i am wondering if it is okay to use bleach or other hair coloring on womens hair.
Praise be to Allah.
Shaykh Ibn ‘Uthaymeen was asked about that and he said:
If the hair is dyed black, the Prophet (peace and
blessings of Allaah be upon him) forbade that when he commanded a man to
change his white hair, but to avoid black. He said: “Change this white hair
but avoid black.” (See Saheeh Muslim, 5476). A stern warning has also
been narrated to the one who does that, namely the hadeeth of the Prophet
(peace and blessings of Allaah be upon him): “There will be people at
the end of time who will dye their hair black like the crops of birds; they
will not even smell the fragrance of Paradise.” (Narrated by Abu Dawood,
4212; al-Nasaa’i, 8/138; classed as saheeh by al-Albaani in Saheeh
al-Jaami’, 8153). This indicates that it is forbidden to change the hair
with black dye. With regard to changing it with different colours of dye,
the basic principle is that it is permissible, unless it is done in the
manner of kaafir women or immoral women, in which case it is forbidden for
that reason, because the Prophet (peace and blessings of Allaah be upon
him) said: “Whoever imitates a people is one of them.” (Narrated by Abu
Dawood, 4031; classed as saheeh by al-Albaani in Irwa’ al-Ghaleel,
5/109).
