The question was asked in Halacha regarding working on Purim. Is it permissible to work on Purim? According to the Halacha, all agree that there is no restriction or problem in doing work on the night of Purim. During the day of Purim, the strict Halacha allows work to be done as well, but the Poskim do bring down that one does not really receive Beracha in the work that he does on Purim day. And therefore, it is preferable that one be Machmir if possible and abstain from working on Purim day.
Regarding taking hair cuts on Purim day, the Ben Ish Chai brings down that it is permissible to take a hair cut if one needs, but only by a Goy (non-Jew.) Chacham Ovadia Yoseph is a little more lenient on this case and permits even a Jew to give the hair cut if the hair cut is being done Lichvod Purim (for the sake of the day.) This year Purim falls out on a Friday, and as such it is permissible also by a Jew to get a hair cut Lichvod the upcoming Shabbat. It would also be permissible for one to shine his shoes on Purim Lichvod Shabbat, and also to cut his nails.
So again, Halacha Lema'ase, working is permissible from the letter of the law on Purim, but for those who are strict to take the day off, upon them will come blessing. Its best and proper to spend time with the family fulfilling the Mitzvot of Matanot LaEvyonim, Mishloach Manot, and Seudat Purim.
