Cellulitis of the scalp is a skin infection that occurs in the deeper layers of the skin and subcutaneous tissue on the scalp. It is a skin infection caused by bacteria, usually, Streptococcus or Staphylococcus is caused by bacteria which can enter the skin through cuts, abrasions, or other skin damage. The infection results in redness, swelling, tenderness, and pain. In severe cases, there may also be blisters or pus-filled bumps. The condition can spread quickly and can be life-threatening if left untreated. Treatment involves antibiotics and wound care, and in severe cases, hospitalization may be necessary.

Causes

The main causes of cellulitis of the scalp are:

  1. Trauma or injury to the scalp: A cut, scratch, or wound on the scalp can provide an entry point for bacteria to infect the skin.
  2. Poor hygiene: Not washing your hair regularly or neglecting to clean cuts or wounds can increase the risk of infection.
  3. Skin conditions: People with skin conditions such as eczema, psoriasis, or acne are more susceptible to cellulitis due to their compromised skin barrier.
  4. Immune system dysfunction: People with weakened immune systems, such as those undergoing chemotherapy or taking immunosuppressive medications, are at higher risk of developing cellulitis.
  5. Contact with contaminated objects: Using contaminated combs, brushes, or other hair-care products can introduce bacteria into the scalp and cause cellulitis.
  6. Close contact with infected individuals: Cellulitis can be spread through close contact with an infected person, such as sharing a hat or hairbrush.

It is important to seek prompt medical treatment for cellulitis of the scalp, as untreated infections can spread to other parts of the body and lead to serious complications.

  3. Cephalexin: This is a type of cephalosporin antibiotic that is commonly used to treat skin infections, including cellulitis.
  4. Clindamycin: This is a type of lincosamide antibiotic that is effective against a wide range of bacteria.

In severe cases, hospitalization may be necessary for intravenous antibiotics and observation.

In addition to antibiotics, other treatments may include:

  1. Pain relief: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help reduce pain and swelling.
  2. Wound care: Keeping the affected area clean and dry is important. A dressing or bandage may be applied to help prevent the spread of the infection.
  3. Immune system support: A healthy immune system can help fight off infections. Eating a balanced diet, getting enough sleep, and avoiding stress can help boost your immune system.

It is important to finish the entire course of antibiotics, even if the symptoms have improved, to prevent the infection from coming back.
