Causes of Hair Loss

• There are many reasons excessive hair loss may occur. Hereditary hair loss is very common. Illness, stress, medications, cancer treatments and thyroid problems are also well known causes. Fungal infections, hair pulling, a protein deficiency and tight ponytails can all lead to hair loss. Hair treatments such as dye and chemical hair straighteners can cause a person to lose hair. Using flat irons and curling irons or brushing wet hair can be causes of hair loss.
  
  

Causes of Red Scalp

• Seborrheic dermatitis is a common cause of red scalp. With this condition, the scalp also tends to look greasy and is usually covered by white and yellow scales. Psoriasis causes red skin which is accompanied by itching and silvery white scales. Contact dermatitis, which is caused by irritation from hair dyes or other hair care products, can cause red scalp. Scalp folliculitis causes red and tender skin.
  
  

Causes of Scalp Bumps

• Scalp folliculitis can cause clusters of small red bumps or a large swollen bump. Folliculitis also causes blisters which may resemble bumps that can break open and crust over. Contact dermatitis causes blisters to form on the scalp. The scales which are caused by seborrheic dermatitis and psoriasis may feel like bumps. Acne of the scalp causes bump-like pimples to form. Many other skin problems and infections can lead to bumps on the scalp, but these are common causes.
  
  

Causes of Scalp Bleeding

• Psoriasis, seborrheic dermatitis, contact dermatitis and other scalp problems which cause dandruff can lead to uncontrollable itching. Scratching an itchy scalp is a common cause of bleeding. Removing the scales which are caused by psoriasis and seborrheic dermatitis can also cause bleeding. Picking at the scalp to remove dandruff can cause it to bleed. Note that there are many other problems which can cause bleeding of the scalp, such as head injuries.
  
  

Considerations

• The most important thing to remember is that the only way to diagnose a skin condition or other problem affecting the scalp or causing hair loss is to visit a doctor. While a primary care physician will often be able to make a diagnosis, it is ideal to visit a dermatologist who specializes in skin care. If symptoms are severe or persistent, a medicated shampoo or topical medication may be able to provide the most relief. Diagnosing the cause of hair loss early on can help further prevent it.
