Hair loss

Hair loss can affect just the scalp or the whole body. It can be caused by hereditary factors, hormonal changes, disease or medication. Anyone can have hair loss, but it is more common in men. Baldness usually refers to excessive hair loss on the scalp. The most common cause of baldness is heredity, along with age.

Symptoms

Hair loss can appear suddenly or gradually, affecting only the scalp or the entire body. Some types of hair loss are temporary while others are permanent.

Gradual hair loss on the top of the head

This is the most common type of hair loss, affecting both men and women as they age. In men, the hairline begins to recede from the forehead. Women usually keep their hairline on their foreheads but have a widening of the hairline.

Circular or patchy bald spots

In some people, light bald spots of the size of coins are present. This type of hair loss usually affects only the scalp, but sometimes it also occurs in the beard or eyebrows. In some cases, there may be itching or pain in the skin before the hair falls out.

Sudden hair loss

A physical or emotional shock can loosen hair.

Hair loss over the whole body

Some medical conditions and treatments such as cancer chemotherapy can cause hair loss all over your body.

Scaling patches spreading on the scalp

This is a sign of ringworm.

Causes

Hair loss is caused when the cycle of hair growth and loss is disrupted or when the hair follicle is destroyed and replaced with scar tissue.

Hair loss is usually related to one or more of the following factors: 

Family history (genetic predisposition): The most common cause of hair loss is an inherited disorder called male pattern baldness or female pattern baldness.

Hormonal changes and medical disorders: Several disorders can cause temporary or permanent hair loss, including the hormonal changes of pregnancy, childbirth, menopause, and thyroid problems. Medical disorders include alopecia areata, which causes patchy hair loss, scalp infections such as ringworm, and a hair pulling disorder called trichotillomania.

Medications and supplements: Hair loss can be a side effect of some medications, such as those used to treat cancer, arthritis, depression, heart problems, gout, and high blood pressure.

Radiation therapy of the head.

A very stressful event: Many people notice a reduction in hair thickness months after suffering a physical or emotional shock. This is temporary.

Certain hair styles and procedures: Excessive styling or hairstyles that pull too much of the hair (such as ponytails or African braids) can cause a type of hair loss called traction alopecia. Hot oil or perm treatments can inflame follicles and cause hair loss. If there is scarring, the hair loss can be permanent.

Risk factors

A number of factors can increase the risk of hair loss, including the following:

  • Family history of baldness on either side of the family
  • Age
  • Significant weight loss
  • Some medical disorders, such as diabetes and lupus
  • Stress

Vitamins

Vitamin B: It is needed to produce hemoglobin in the blood, which is essential to get oxygen from the lungs to the body tissues, including hair.

Vitamin B5: Prevents hair loss and helps prevent loss of hair color.

Vitamin B6: The deficiency of this vitamin is one of the main causes of baldness. It also intervenes in the production of keratin, which gives the hair shine.

Vitamin C: It is the main nutrient for the production of collagen, an essential part of hair fiber. The lack of this vitamin can cause the hair to break or weaken.

Vitamin E: Tonifies the scalp and helps the absorption of oxygen, thus increasing the renewal and growth of hair.
