May women wear their hair short or must they have long hair? May they have fringes?
All perfect praise be to Allah
Imam Bukhari narrated from Ibn Abbas that the Prophet (Sallallahu Alaihi wa Sallam) "Has cursed men who make themselves like women and has cursed women who make themselves like men"
So, as long as you are not falling in this category, it is fine to cut your hair.
It was narrated in Saheeh Muslim “The wives of the Prophet (peace and blessings of Allaah be upon him) used to cut their hair until it came just below their ears.” (al-Hayd, 320)
Al-Nawawi said: this indicates that it is permissible for women to cut their hair short.
But keep in mind first hadees and also not to intimate kuffar or immoral women, as it is also prohibited, and you are good to go.
Also, Shaykh Ibn Baaz (may Allaah have mercy on him) said:
We do not know anything (to disallow) cutting women’s hair. What is forbidden is shaving it. You should not shave your hair but you may cut it and reduce its length or volume; we know of nothing wrong with that. But that should be done in a proper manner which will please you and your husband. You should come to some agreement with him on a kind of haircut that does not resemble kaafir women, because if you leave it long, it will be a lot of trouble to wash it and comb it. So if the hair is very long or thick, and the woman cuts it to reduce its length or volume, that doesn’t matter. Cutting some of it will make it more beautiful, which will please both the woman and her husband. So we do not know of any reason to disallow that. But shaving it altogether is not permissible, except in the case of sickness. And Allaah is the Source of strength.
