Causes of Hair Thinning in Teenagers 

Below are several potential reasons why some teenagers may suffer from hair thinning and not others. This applies to both male and female teenagers. 

  • Genetics

Androgenetic alopecia is a hair loss condition that is brought about by genetics. It is also referred to as male pattern baldness or female pattern baldness. You will notice this type of hair loss because it occurs predictably. Receding hairline is among the signs of male pattern baldness where gradual hair loss will take either U, M, or V hairline shape. This usually happens at the crown. Fortunately, this condition can be treated with the best hair transplant procedures. 

In women, hair loss from a female pattern baldness condition will affect parts of the scalp. In most cases, such hair loss conditions happen to adults, but occasionally, it can also happen to teenagers. This type of hair thinning condition rarely happens to teenagers. Currently, its prevalence is hard to tell. However, a teenager can expect to suffer from hair loss if a close relative suffers from hair loss. 

  • Alopecia Areata 

So, what is alopecia areata is A hair loss condition that causes hair strands to fall out and leave patches in parts of the scalp called Alopecia areata. It is an autoimmune condition where the body’s defense system starts attacking healthy cells in the body, mistaking them for foreign invaders. Sometimes, hair follicles become casualties of such conditions causing them to shrink and become dormant. If you suffer from such a condition, you will notice that the eyebrows, eyelashes, body, and scalp start losing hair. 

At some point in life, Alopecia areata will affect about 2% of the population. This hair thinning condition may occur early in life, although it mostly affects 30 years and above. 

  • Malnutrition

Malnutrition may also be a reason why some teenagers have thinning hair. This comes as a result of not eating nutritious foods in your diet. In other words, it is the lack of critical nutrients in the body. Eating too much or not eating enough food may lead to malnutrition. Malnutrition may be caused by insufficient food, eating disorders, dietary imbalances, or digestive medical conditions. Some of the hair thinning nutrient deficiencies include lack of:

  • Zinc 
  • Vitamin E
  • Vitamin A
  • Iron 
  • Vitamin C
  • Niacin 
  • Thyroid conditions
  • Vitamin D
  • Folic acid
  • Biotin 
  • Selenium 

The thyroid is a medical condition that causes the body to produce large amounts or little thyroid hormones. This condition may cause brittle hair or hair loss. Once a thyroid condition attracts a person, it causes uniform thinning across the scalp. Although prolonged or severe thyroid disease may cause hair loss, hair may grow again with proper treatment and care. 


Teenagers affected by hair loss go through a lot because most of them don’t understand that they can also suffer hair thinning. If you suspect that you are suffering from any kind of hair thinning as a teenager, seek medical attention from a skin specialist or a dermatologist. With a few tests, the doctor will explain the cause of hair loss so that you can get the best hair transplant procedure as a treatment.
