Using wigs, etc. for women:
For the sake of fashion, women are getting their hair cut. They are having different types of hairstyles like u-cut, v-cut, step-cut, etc. They are also using wigs. Does the Shariah permit this?
Adorning and beautifying herself is the very nature of women. This is her natural right. For this reason, Islam has not prohibited women from makeup, etc., but has declared it commendable (Mustahab) for them. Islam has permitted women that they take good care of themselves, wear colorful clothes, beautify themselves with jewelry, use henna (Mehndi), use Kohl.
For makeup, etc. guidelines have been framed. In the Hadith, women have been prohibited from making themselves similar to men. There is a Hadith in Sahih Bukhari:
Translation of Hadith: The Prophet of Allah Ta’ala (Sallallahu alaihi wa sallam) has cursed the men who become similar to women and women who become similar to men.
Thus, it is not correct for women to get their hair cut in step-cut, u-cut, v-cut, etc.
Among all creation, human beings have been given the place of honor. For this reason, using human hair after they have been severed from the body is not permissible in the light of the Shariah. This is against the honor of human beings. However, excepting pig hair, it is permissible to use hair of any other animal or even artificial hair. Thus, using wigs in itself is not impermissible.
Modern hair for women:
Nowadays, some women who into fashion a lot keep hairstyles like those of men. Does Islam allow it?
It is permissible for women to beautify themselves within the limits prescribed by the Shariah. Women are strictly forbidden against being similar to men. There is a Hadith in Sahih Bukhari, Vol. 2, Pg No. 478:
Translation of Hadith: It has been narrated on the authority of Hadhrat Abdullah bin Abbas (May Allah be well pleased with them) that he said: The Prophet (Sallallahu alaihi wa sallam) has cursed those men who try to look similar to women and those women who try to look like men.
Thus, women having haircuts, which are similar to men is as per Shariah, Makruh (undesirable) and very much looked down upon. Such, women who do this are liable to be cursed and it is a sin. As given in Raddul Muhtaar, Vol. 5, Pg No. 261.
For the sake of getting ready women are trimming their hair. Women are implying various kinds of hairstyles like v-cut, u-cut, step cut, etc… In the same ways they are applying wigs. On this the question arises that whether this is advisable in the Islam or not.
Tying hair in a bun
Tying the hair in a bun is permissible, but tying a bun in the middle of the head like the hump of a camel is impermissible.
There is a Hadith in Sahih Muslim in which the Holy Prophet (Sallallahu alaihi wa sallam) declares such women to be a group of hell who are nude in spite of wearing clothes i.e. they wear revealing clothes, who attract others to themselves or are attracted towards others, their heads are like the hump of a camel. They will not enter Jannah and will not get its fragrance and indeed, the fragrance of Jannah can be heard from such and such a distance. (Sahih Muslim, Hadith No. 2128)
