What are scabs?
The primary purpose of a scab is to protect the wound from bacteria in order to prevent the wound from being infected.
Should scabs be removed?
How long does a scab take to heal?
How to avoid scabs
First, clean the wound in order to reduce the risk of infection. Covering your wound with an Elastoplast plaster will prevent scabs from forming, reducing the likelihood of the wound causing a scar, allowing your skin to heal flawlessly. The Elastoplast Fast Healing Plaster can be used to prevent dry scabbing as it keeps the wound moist while selectively absorbing the wound fluid which leads to accelerated healing.
Causes of scabs
Scabs are primarily formed to protect your wound against blood loss and infection. Blood clot cells (platelets) start to clot in order to prevent any more blood or fluids from leaving the body. As the blood on the wound begins to dry it creates the crusty scab layer over the wound. Scabs can form as a result of:
- bacterial infection
- Bug bites
- cuts, grazes and scratches.
- fungal infection
- Infected scalp injury
- Seborrheic dermatitis
Scabs on the scalp
Scabs on the scalp can largely be treated in the same manner as scabs anywhere else on the body. In some cases they can be a symptom of a separate condition that may require further treatment, such as:
- Scalp psoriasis is an infection that develops symptoms of itching or flakiness on patches of skin that looks like dandruff. Scratching the affected areas can cause scabs on the scalp and lead to symptoms such as severe hair loss.
- Contact dermatitis is a type of eczema that occurs when an irritant substance comes into direct contact with a person’s skin. Blistered scalp skin can be a symptom of contact dermatitis which can also lead to scabs on the scalp.
- Folliculitis is an infection of the hair follicles that can cause pimples or sores from shaving. They can also lead to scabbing and scarring if picked.
- Seborrheic dermatitis is a common condition that causes red, itchy, and flaky skin. This rash often occurs on the scalp or near the hairline and could cause scabbing if itched excessively.
Yellow scabbing can also imply that you may have impetigo, which can commonly be caused by bacterial infection. Impetigo can spread around the body, to other people and also lead to fevers. It is advised to see a doctor if you feel unwell with a wound that you suspect is heavily infected.
