A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste, respectively.
If you are a man and your Hajj is the first Hajj, you must shave your head on the day of Eidul Adhha as one of the obligatory acts of Haj according to most of the scholars.
If your Hajj is not the first Hajj, it will be highly recommended to shave your head.
Shaving the head is not permissible for women.
The oil prevents water from reaching the hair or the skin
So one should make sure that the water comes into direct contact with their hair or skin.
You can leave a little area of the head without oil in order to do a correct wudhu.
No. It is not permissible for female to shave her head for any reason except medical emergency like necessary head operation etc. Even in Hajj when shaving the head is compulsory on men, it remains Haraam ( forbidden) on women to shave her head.
Not all your head nor all your feet must be dry when wipe on them in Wudhu. Just part of the front part of the head, and one or more figures must be dry. The wiping must affect that front part of the head and one or more fingers. The affect is not transfer the wetness from the hand to the wiped areas.
Most of our Maraaji' of Taqleed state that covering the face of the female is not obligatory except when not covering the face can cause harm, but in usual cases, it is obligatory to cover all the hair, head, neck and whole body except the face and the hands.

It is not compulsory to cover the head during prayer. However it is recommended, especially by wearing a turban.
With prayers for your success.
Woman must cover her hair and body during Prayers even if she is away from any Non Mahram who can see her.
Man does not need to cover his head during Prayers although many Muslims do that due to cultural reasons. It is recommended for man to wear a turban during Prayers, not just to cover his head.
If there is no non-mahram there, there is no need to cover her hair
If you turn away towards the right or left side - regardless of whether your back is towards Qibla or not - due to forgetting, you should start a new prayer as soon as you remembers, if there is time left even for one unit (rakat). If there isn't time enough to pray a new prayer, or at least one rakat, then you should continue with the same prayer towards Qibla, and the prayer will not be qaẓa. Similar rule applies to the one who has deviated because of the external force.
If there is an excuse, like, forgetting or an external force, like a strong wind blowing, which turns him away from Qibla, the prayer will be valid if one has not deviated towards the right or the left. It is necessary that one returns to the direction of Qibla as soon as the excuse disappears.
