Can Muslim women trim hair for aesthetics without resembling men/non-Muslims?

My question here is that is it allowed to a woman to cut her hair a little bit from the bottom of the length, so as to provide strength to the hair and bring the hair in one level to increase its beauty? It has nothing to do with the resemblance with men or any kafir woman. It is just for the safety of hair. One more thing I want to know is, can I have the exact hadith which is generally quoted in this regard. The meaning of the quoted hadith is something like follows:
“It is generally said that if a woman runs scissor on her hair, she will never smell the fragrance of Jannah.”
