Hair loss

Hair loss is subjected to something in which hair fall happens as 70-110 hair strands every day. It is known as Alopecia Areata.  Alopecia Areata means "hair loss in areas". In the majority of cases hair loss is a normal process of aging, and not a disease and can happen from many other reasons.

Reasons, occurrence and risk factors

Most people who develop Alopecia Areata are actually healthy and are not among skin problems. When it does occur, it tends to start during the late teenage years, early childhood, or early adulthood. However, it can attack at any age.

The major other risk factor of this problem is:

  • Physical stress: surgery, illness, anemia, rapid weight change.
  • Emotional stress: mental illness,
  • Trauma
  • Tension
  • High Blood pressure
  • Thyroid abnormalities
  • Medications: High doses of Vitamin A, blood pressure medications, Gout medications.
  • Hormonal causes such as pregnancy, birth control pills, and menopause
  • Hair loss may also occur due to dieting.
  • Frequent shampooing contributes to hair loss.
  • Hats cause hair loss
  • Dandruff
  • Genetic Reasons

Symptoms

  • Gradual thinning on top of head: This is the most common type of hair loss, affecting both men and women. In men, hair often begins to recede from the forehead in a line that resembles the letter M. Women typically retain a line of hair at the forehead but experience a broadening of the part in their hair.
  • Circular or patchy bald spots: Some people experience smooth bald spots, often about an inch across. This type of hair loss usually affects just the scalp, but it sometimes also occurs in beards or eyebrows. In some cases, your skin may become itchy or painful before the hair falls out.
  • Sudden loosening of hair: A physical or emotional shock can cause hair to loosen. Handfuls of hair may come out when combing or washing your hair or even after gentle tugging. This type of hair loss usually causes overall hair thinning and not bald patches.
  • Full-body hair loss: Some situations and medical treatments, such as chemotherapy for cancer, can result in the loss of hair all over your body. Loss of eyelashes and eyebrows, as well as hair in the nose and ears also happen in this problem. The hair usually grows back after treatment ends.

Signs and Test

In rare cases, some hair loss types can include complete loss of hair on the head or complete loss of hair on the face and body. Hair loss often occurs in people whose family members have other autoimmune diseases, like diabetes or rheumatoid arthritis.

These are some of the tests which are performed to determine the actual reason behind the problem:

Blood Tests
Blood tests are performed to determine if you have a medical condition that causes hair loss, such as thyroid disease, diabetes or lupus.

Biopsies and Pull tests

  • During a pull test, several dozen hairs are gently pulled to see how many come out. This helps determine the stage of the hair losing process.
  • Scraping samples taken from the skin or from a few hairs plucked from the scalp can help verify whether an infection is causing hair loss
  • In punch biopsy test, the doctor uses a circular tool to remove a small section of your skin’s deeper layers to determine the exact reason for hair loss.

  • Applying less chemical on hair
  • Regular testing if anybody having genetic problem
  • Less salon styling
  • Keeping your bowel system clean
  • Keeping your hair clean from dust and dandruff
