Regarding your question, Sheikh M. S. Al-Munajjid, a prominent Saudi Muslim lecturer and author, states:
Trimming Hair and Nail by One Who Wants to Offer Sacrifice
The Sunnah indicates that the one who wants to offer a sacrifice must stop cutting his hair and nails and removing anything from his skin. This starts from the beginning of the ten days until one offers his sacrifice. The Prophet Muhammad (peace be upon him) said; “When you see the new moon of Dhul-Hijjah, if any one of you wants to offer a sacrifice, then he should stop cutting his hair and nails until he has offered his sacrifice.” (Muslim)
However, if a person does any of these things deliberately, he must seek Allah’s forgiveness but should offer not (an extra) sacrifice in expiation. Whoever needs to remove some hair, nails, etc.; because it harms him, such as having a broken nail or a wound in a site where there is hair, should do so, and there is nothing wrong with that.
📚 Read a different fiqhi opinion on this question:
First of Dhul-Hijjah: Shaving Wrong Day Invalidates Udhiyah?
Though the state of ihram is so important, it is permissible to cut one’s hair if leaving it will cause harm.
There is nothing wrong with men or women washing their heads during the first ten days of Dhul-Hijjah. The Prophet only forbade cutting the hair, not washing it.
If a person, having no previous plan to offer a sacrifice, cuts his hair or nails during the first ten days of Dhul-Hijjah, then decides later to offer a sacrifice, then he must refrain from cutting his hair and nails from the moment he makes this decision.
Some women are in the habit of delegating their brothers or sons to make the sacrifice on their behalf, thinking that this gives them permission to cut their hair during these ten days.
This is not correct, because the ruling applies to the one who is offering the sacrifice, whether or not he (or she) delegates someone else to carry out the actual deed. The prohibition does not apply to the person delegated, only to the person who is making the sacrifice according to the hadith.
The person who is sacrificing on behalf of someone else, for whatever reason, does not have to adhere to this prohibition.
This prohibition appears to apply only to the one who is offering the sacrifice, not to his wife and children, unless any of them is offering a sacrifice in his or her own right. The Prophet (PBUH) used to offer sacrifice “on behalf of the family of Muhammad.” There are no reports that indicate that he forbade them from cutting their hair or nails at that time.
Things to Do during Dhul-Hijjah Days
Concerning the types of worship that a Muslim can do during these ten days, one must understand that these days are a great blessing from Allah to His servants.
It is the Muslim’s duty to appreciate this blessing and seize the opportunity, by devoting these ten days to paying more attention to striving hard in worship. Among His blessings to His servants, Allah has given us many ways in which to do good and worship Him, so that the Muslim may be constantly active and consistent in his worship of his Lord. Among the good deeds which the Muslim should strive to do during the first ten days of Dhul-Hijjah are:
1- Fasting
It is Sunnah to fast on the ninth day of Dhul-Hijjah. The Prophet urged us to do good deeds during this time, and fasting is one of the best of deeds.
The Prophet used to fast on the ninth of Dhul-Hijjah. Hunaydah ibn Khalid quoted some of the wives of the Prophet as saying: “The Prophet used to fast on the ninth of Dhul-Hijjah, on the day of Ashura, on three days of each month, and on the first two Mondays and Thursdays of each month.” (An-Nasa’i)
2- Takbir
It is Sunnah to say takbir, tahmid, tahlil, and tasbih during the first ten days of Dhul-Hijjah, and to say it loudly in the mosque, the home, the street and every place where it is permitted to remember Allah and mention His name out loud, as an act of worship and as a proclamation of the greatness of Allah, may He be exalted.
Men should recite these phrases out loud, and women should recite them quietly. Allah says: “That they might witness things that are of benefit to them (i.e., reward of Hajj in the Hereafter, and also some worldly gain from trade, etc.), and mention the name of Allah on appointed days, over the beast of cattle that He has provided for them (for sacrifice)… ” (Al-Hajj 22:28)
The majority of scholars agree that the “appointed days” are the first ten days of Dhul-Hijjah. Ibn Abbas: “The ‘appointed days’ are the first ten days (of Dhul-Hijjah).”
Takbir at this time is an aspect of the Sunnah. People forgot this sunnah so much so that one hardly ever hears takbir, except from a few people.
This takbir should be pronounced loudly, in order to revive the Sunnah and as a reminder to the negligent. There is sound evidence that Ibn `Umar and Abu Hurairah (may Allah be pleased with them both) used to go out in the marketplace during the first ten days of Dhul-Hijjah, reciting takbir, and the people would recite it after him. The idea behind reminding the people to recite this is that each one should recite it individually, not in unison, as there is no basis in the Shari`ah for doing this.
3- Performing Hajj and Umrah
One of the best deeds that one can do during these ten days is to perform Hajj to the Sacred House of Allah. The one whom Allah helps to offer Hajj to His House and to perform all the rituals properly is included in the words of the Prophet (peace and blessings be upon him): An accepted Hajj brings no less a reward than Paradise.” (Al-Bukhari and Muslim)
4- Doing more good deeds in general
This is because good deeds are beloved by Allah and earn one a great reward. Whoever is not able to offer Hajj should occupy himself at this blessed time with acts of worship, offering Prayers, reading the Quran, remembering Allah, making supplications, giving in charity, showing dutifulness to parents, maintaining the ties of kinship, enjoining what is good and forbidding what is evil, and other good deeds and acts of worship.

6- Sincere repentance

Almighty Allah knows best.
