WOMEN HAVING MEN'S HAIR STYLES

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)
