Meaning and formation

A rash is a reaction of a skin that can result in swelling, reddening, or blotching of the affected area. A rash usually occurs alongside bumpy, scaly, flaky or pus-filled bumps.

Not just on the scalp, it can occur on face, nose, legs, stomach, bottoms and other parts of the body.  The occurrence or the patterns, shape, size or color of these rashes normally vary.  The severity will also depend on causes and medical history of a patient.

According to Dr. Aruna Prasad, Consultant Dermatologist, and Cosmologist, “rashes on the scalp could be for various reasons. One is using of cosmetics. So the use of a particular shampoo, hair oil or hair dye can cause rashes. Another thing could be hair root infections and another”

Why do I have a rash on my scalp

In case you have them, below are the most common causes include:

The scalp skin can become irritated when it comes into contact with allergens such as cosmetics, soaps or detergents. Irritants such as ingredients found in shampoo, conditioner, hair gel and other beauty products might also cause irritation leading to rashes.

Such reactions are usually referred as irritant dermatitis. Symptoms such as itching, swelling, or small bumps may accompany the rashes, and can easily lead to secondary infections.  Try to avoid hair care products that have harsh chemical ingredients, fragrance or dye since they play a greater role in this issue.

2. Scalp psoriasis

This is a skin condition that results in thickened, red and scaly patches on the skin. Psoriasis can develop at any age but very common between the age of 15-25. It runs in families but can also be triggered by these conditions: certain medications, injury to the skin, infections, emotional stress. Though the exact cause of psoriasis is not known, it has been linked to autoimmune disorders.

Psoriasis can cause a rash in any part of the body. According to Skinlight.com, “these patches are frequently seen on the elbows, knees, back, buttocks, and scalp, and they are usually seen on both sides of the body.”

Bacteria are the most common microbes in the human body. There are certain types that occur in the body naturally and form part of the normal skin flora. We should bear in mind that not all bacteria are harmful but some many of them are linked to diseases. Bacterial infections are among the causes of rash on the scalp. Here are various types of bacterial infections that can be associated these infections:

b) Scalp Impetigo

This is a common bacterial infection of the superficial layers of the skin. When it extends deeper on the skin, it will be referred to as cellulitis. The bacteria that are connected to the occurrence of impetigo are Streptococcus pyogenes or Staphylococcus aureus. This condition will often cause a rash as a secondary infection to head lice, fungal infections or other diseases.

4. Fungal infections

Fungi can also be responsible for many scalp problems including rash. Actually, what leads to this condition here is the overgrowth of fungi or the skin reaction to the presence of fungi leading to skin inflammation.

There are two known types of fungi-yeasts and dermatophytes. All these types can lead to development of scalp problems (rash). Below are some common fungal infections in this area:

Other symptoms also include pus-filled bumps (kerion).

More risk factor for Tinea Capitis are:

  • Lack of bathing or washing the hair on regular basis.
  • Having wet skin for long period of time

b) Yeast

There group of yeast that is usually found on the skin surface, and they are often called Malassezia. They are often not harmful but can trigger some skin conditions under certain conditions.
