Is it better for one who performs Hajj as a mutamatti' and has a month between him and the day of Tarwiyah to shave his head rather than shorten his hair?

The questioner : Shaykh, it is known that any hair, even if it is short, suffices in place of shaving?

The Shaykh : About what?

The questioner : Regarding the act of shaving, or rather, exiting the state of ihram by shaving, meaning, so if the mutamatti' performs 'Umrah in the months of Hajj, especially if there is a period of a month, for example, between this 'Umrah and his Hajj, do we not tell him that shaving is better?

The Shaykh : Yes, if possible, he should exit the state of ihram.
