Combing with a Comb during Shiva

Is it permitted to comb with a comb during Shiva?

It is permitted to comb with a comb for both men and women during Shiva, and certainly during the thirty days.

The Tosafot in Tractate Moed Katan, page 19, column 2, in the commentary "Atiya" writes: "There are those who say that it is forbidden for a mourner to comb his head after seven days because it is said (Nazir, page 42): 'A nazir washes and untangles his hair but does not comb,' and we learn from the nazir. However, this does not seem correct, as for a nazir it is certainly forbidden even to pull out hair, but regarding mourning, which is for beautification, it is not. And at the time of the act, I asked my teacher RIBA, and he permitted me."

Similarly, Rabbeinu Yerucham (Nechach part 2, page 232, column 74) writes in the name of Rashi that it is permitted to comb even within seven days, as there is neither pleasure nor joy in it. Mordechai in Moed Katan, chapter 997, writes that some permit combing, and some wish to forbid it for all thirty days. The Smak writes that one may comb his head only after seven days. And the Shulchan Aruch, chapter 380, paragraph 6, writes: "To comb (one's head) with a comb is permitted even within seven days."

In the Shach, there, section 3, it is brought that there is a version in the Shulchan Aruch that permits only women and not men, and so writes the Bach in the name of the glosses of the Smak in the name of AZ, that it is permitted specifically for women and not for men. And he writes that from the words of the Beit Yosef it is evident that it is permitted for both men and women, as it brings neither joy nor pleasure.

Similarly, it is implied from the words of the Shaarei Tzion, chapter 551, section 28, where it is written that in mourning they are lenient and do not differentiate between men and women.
