When someone has a rash, then this means that he or she has a change in the skin color or texture. In the most cases rashes are caused by skin inflammation and there are many causes for skin inflammations. Your skin can become itchy, bumpy, scaly or otherwise irritated. There are many different causes for rashes such as certain diseases (such as measles and chickenpox), cosmetics, medications and allergies.

Causes of rash

One of the most common causes for rashes is the contact dermatitis. It is known that the contact rashes are happening when the skin is coming into direct contact with a foreign substance which is causing an adverse reaction that leads to a rash. The resulting rash may be inflamed, red or itchy. Here are some possible causes of contact dermatitis:

  • Touching poisonous plants, such as poison sumac, poison ivy or poison oak
  • Being in contact with chemicals in rubber, elastic or latex
  • Using dyes in clothing
  • Using beauty products, soaps and laundry detergent

Also there are some medications which can cause rashes and they form as a result of:

  • Photosensitivity to the medication
  • A side effect of the medication
  • An allergic reaction to the medication

Also there are other possible causes of rashes such as

  • RA which is an autoimmune disease that can cause a rash to form on many parts of the body
  • Lupus erythematosus which is an autoimmune disease that is triggering the rash on the cheeks and nose. This rash is also known as a butterfly or malar rash.
  • Seborrheic eczema which is a type of eczema that most often is affecting the scalp and it causes redness, scaly patches and dandruff. Also it can happen on the nose, mouth and ears. When babies have this condition, then it is known as crib cap.
  • Psoriasis which is a common skin condition. It is causing a scaly, itchy and red rash to form along the scalp, joints and elbows.
  • Eczema is also known as atopic dermatitis. This is a rash which is primarily happening in people who suffer from allergies or asthma. This rash is often reddish and itchy with a scaly texture.
  • A rash sometimes can develop in the area of bug bite. If you have been bitten by a tick, then you should concern about it because they can transmit disease.

Children can also develop rash as a result of illnesses such as:
