Dyeing the hair black if there is no intention to cheat or deceive

It was narrated from the Prophet (peace and blessings of
Allaah be upon him) that dying the hair black is not allowed. That is
mentioned in the hadeeth of Jaabir ibn ‘Abd-Allaah (may Allaah be pleased
with him) that Abu Quhaafah, the father of Abu Bakr al-Siddeeq, was brought
to the Prophet (peace and blessings of Allaah be upon him) to give his
oath of allegiance, and his hair was completely white. The Prophet
(peace and blessings of Allaah be upon him) said: “Change this, but avoid
black.” Narrated by Muslim. 

Dyeing the hair black is not allowed, whether the hair was
red or white. The scholars have stated that the reason why it is not allowed
to dye the hair black is because of the deception involved, as it makes a
person appear to be something he is not, especially since a person’s age may
be known from the colour of his hair, whether it is black or white or a
mixture of the two. So dyeing the hair black makes him look young when he
may be middle aged or an old man. 

Based on this reason, if there are no white hairs and there
is no intention to deceive, as in the case asked about here – where the
questioner’s hair was black then its colour changed to red – is it
permissible to dye the hair black? 

It better to be on the safe side and avoid that, because of
the wording of the hadeeth and in accordance with it, especially since the
reason mentioned – namely cheating and deception – is an implicit reason
which some of the scholars stated was what was meant here, but it was not
stated expressly by the Prophet (peace and blessings of Allaah be upon
him). 

It should be noted that the Muslim woman understands the
importance of time, and recognizes that this world is a preparation for the
Hereafter.  So she should not spend much of her time or most of her time on
matters of her body, clothing and adornments at the expense of her worship,
educating her children, calling others to her religion and treating others
with kindness. That does not mean that she should not adorn herself, rather
she should adorn herself with that which Allaah has permitted, within
reasonable limits as regards how she does it and how much time she spends on
that. 

Moreover she should not pay attention to every new thing that
comes along, adopting and following every new fashion that she sees. That
may lead her to imitate kaafir women and immoral women, let alone wasting
time and money that she could put to better use which would be more
beneficial to herself and to her ummah. 

And Allaah is the One Whom we ask to guide us to do and say that which is right and true.
