How to wash your hair if you have a head injury

If you have a head injury, it is best not to wash your hair if the doctor specifically tells you not to. If you really feel uncomfortable, you can buy a headgear to cover the wound and then wash your hair. But remember to be more careful when washing your hair. It is best not to let water get on the wound, otherwise it will cause infection. If the wound is infected, it will be very troublesome. It will not only endanger your health, but may also leave scars.

How long after surgery can the wound be wet?

1. How long does it take for the wound to be exposed to water after surgery?

Generally speaking, stye heals quickly, usually within 3 days. If there is no obvious exudation from the stye after 3 days, and the stye heals well, you can take a bath in water.

Do not get the wound wet or dirty before it heals. If it gets wet, it must be wiped dry immediately and betadine applied.

After the operation, the doctor will apply cosmetic glue on the wound and then cover it with gauze. The gauze can be removed after 4 days, or immediately if it is damp. The cosmetic glue should be removed after about a week and replaced with ventilation paper tape.

After showering, tear off all the tape on the wound, wipe the wound dry (no need to apply medicine), and then stick 2 pieces of 3M breathable paper tape, 2.5 cm wide, along the wound.

2. What should be paid attention to in postoperative wound care?

For those with flatter wounds, use breathable paper tape. For pregnant women who are prone to allergies or scars, use silicone gel as directed by the doctor.

Gently massage the wound with your fingers for 3 to 5 minutes every day to reduce scarring.

Avoid direct sunlight exposure to the wound, which will darken the scar color. If there are scabs, do not scratch them with your hands, let them fall off naturally.

If the abdominal wound is red, swollen, burning, painful, or has exudate, please return to the hospital for treatment.

3. What is the healing process of surgical wounds?

Acute inflammatory phase:

The early changes of the wound include varying degrees of tissue necrosis and vascular rupture and bleeding. An inflammatory reaction will occur within a few hours, manifested as congestion, serous exudation and leukocyte guerrilla warfare, resulting in local redness and swelling. The main white blood cells were neutrophils, which turned into macrophages after 3 days. The fibrinogen in the blood and exudate in the wound quickly coagulates to form clots. The surface of some clots dries to form scabs. The clots and scabs play a role in protecting the wound.

Cell proliferation phase:

After 2 to 3 days of wound contraction, the entire layer of skin and subcutaneous tissue at the edge of the wound moves toward the center, and the wound shrinks rapidly until it stops around 14 days. The significance of wound contraction is to reduce the wound surface. Experiments have shown that wounds can even be reduced by 80%, but the degree of wound reduction in each specific case varies depending on the animal species, wound location, wound size and shape. Wound contraction is caused by the pulling effect of newly generated myofibroblasts at the wound edge and has nothing to do with collagen. Because the time when wound contracts is exactly the time when myofibroblasts proliferate. 5-HT, angiotensin and norepinephrine can promote wound contraction, while glucocorticoids and smooth muscle antagonists can inhibit wound contraction.
