Is there any way I can trim my hair during the omer? It looks unruly, and it makes me anxious. Also, my work requires me to look especially groomed, and people are beginning to comment. Is there anything I can do before lag ba’omer?
If leaving your hair long will affect your income, it is permitted to trim your hair to the degree required (see Iggros Moshe, Vol. 4, no. 102; Kaf Ha-Chaim 493:19).
However, you should weigh up the decision carefully — only if there is a sincere concern for one’s income is trimming hair permitted.
Looking unruly in itself is not a reason to permit a haircut (it should have been taken before Pesach), but if the anxiety reaches a level that affects your daily function, it will be permitted.
