630 Lexical Explanation:
«المحلقين» is the active participle form derived from "tahleeq." These are the people who shave their heads at the time of becoming lawful (halal) after Hajj and Umrah. "Halaq" actually means to remove the hair completely from the roots.
«والمقصرين» is a conjunctive addition, meaning you should also say: «والمقصرين». And «تقصيعر» refers to trimming the hair, in which the hair is not removed from the roots. This hadith indicates the virtue of shaving the head.

Hadith Commentary:
(1)
Shaving the head during Hajj or Umrah is superior, and trimming the hair is permissible, because the Messenger of Allah (sallallahu alayhi wa sallam) supplicated for mercy and forgiveness for those who shaved their heads two or three times, and for those who trimmed their hair, he uttered supplicatory words once.
These supplicatory words were also spoken by him on the occasion of the Farewell Pilgrimage (Hajjat al-Wada‘), as is narrated from Umm Husayn (radi Allahu anha) that the Messenger of Allah (sallallahu alayhi wa sallam) supplicated three times for those who shaved their heads and once for those who trimmed their hair on the occasion of the Farewell Pilgrimage.
(Sahih Muslim, Kitab al-Hajj, Hadith: 3150(1303))
And on the occasion of the Treaty of Hudaybiyyah, he supplicated in the same manner, as Ibn Ishaq has explicitly stated.
The Arabs were accustomed to letting their hair grow and to keeping it long as an adornment.
Among them, shaving the head was not customary at all, so on the occasion of the Treaty of Hudaybiyyah or Hajj, some individuals did not like to shave, whereas the majority, upon hearing your command or seeing your action, hastened to obey your instruction or to act upon your way. Therefore, you supplicated three times for those who shaved their heads. Thus, it is mentioned in the hadith that it was asked of the Messenger of Allah (sallallahu alayhi wa sallam): Why did you supplicate three times for those who shaved their heads and once for those who trimmed their hair? He replied:
“Those who shaved their heads did not hesitate at all, rather they were foremost in obeying my command.”
(Sunan Ibn Majah, Kitab al-Manasik, Hadith: 3045)

It should be clear that if one performs Umrah a few days before Hajj and fears that after shaving (halq), the hair will not grow back by the tenth of Dhu al-Hijjah, then in such circumstances, it is preferable for the one performing Umrah to trim the hair, so that shaving (halq) can be performed at the time of Hajj.
Those companions who performed Umrah with the Messenger of Allah (sallallahu alayhi wa sallam) trimmed their hair on that occasion, as we have already clarified earlier.
