Main causes of Children's Hair Loss

Posted by Emilienne Rebel on

Causes of Hair Loss in Children:

Is your kid losing hair for apparently no reason? It’s better to look for the root cause early before the little one loses significant amounts of hair and his/her self-confidence. Whether a medical or non-medical cause, it’s necessary to get hair loss treated immediately.

Bold Beanies offer hair loss beanies that fit snugly (but not tight!) on the hat to allow a child to run and play without worrying about the hat moving. They come in a vast array of colours and prints so they are sure to find something they will actually enjoy wearing.

When it comes to hair loss in children, there are various factors at play. While many causes require a doctor’s attention, others will resolve on their own with time. For example: newborns lose their hair during the first few months of life. But this is eventually replaced by permanent hair. In other cases, there are reasons that need immediate medical assistance.

Non- Medical Causes of Hair Loss in Children:

  • Harsh chemicals used to treat hair
  • Hair dried with high heat
  • Braids, ponytails and barrettes tied too tight
  • Combs or brushes used on wet hair, leading to hair fall

Medical Causes of Hair Loss in Children:

There can be various medical causes behind children losing hair, especially children aged 26 months and above. 

1. Tinea Capitis:

Commonly known as ringworm of the scalp, this is a fungal infection. It can surface as scaly patches of hair loss on the head, either round or oval. Hair shafts may be broken off at the surface of the scalp and resemble black dots.
Pediatricians prescribe:
  • Oral antifungal treatment and
  • Using an antifungal shampoo to decrease shedding of the fungus.
  • It is contagious; avoid sharing any objects that come in contact with the child’s head.

2. Alopecia Areata:

It is a non-contagious condition, caused by the body’s immune system attacking the hair follicles. It also surfaces as slick/smooth, round or oval patches of hair loss, without scaling or broken hairs. Some children also have pitting and ridging of the nails. While there is no permanent cure, proper treatment can control the disease. Some cases progress to Alopecia Totalis or complete loss of hair, while others lead to Alopecia Universalis or total loss of body hair.

3. Trichotillomania:

Hair loss is caused by children pulling, plucking, twisting, or rubbing their hair. Patches are typically seen on the side of the child’s dominant hand. This is often triggered by stress or anxiety in the child’s environment. Councelling is the best approach to rectify the source that triggered the habit.

4. Telogen Effluvium:

It is a condition in which sudden or severe stress interrupts the normal cycle of hair growth. This can be caused due to:
  • extremely high fever
  • surgery under general anesthesia
  • the death of a loved one
  • a severe injury
  • due to certain medications

In this case, the hair follicles stop growing prematurely and enter the resting phase. Subsequently it leads to excessive hair loss, resulting in partial or complete baldness. It has no treatment. Once the stressful event is over, full hair growth usually returns within six months to a year.

5. Nutritional Imbalance:

Hair loss can be a symptom of deficiencies/excess in certain nutrients, including:

  • Deficiency in Vitamin H, or biotin, a Vitamin B complex, that helps to metabolise carbohydrate into glucose energy.
  • Deficiency in Zinc, an essential mineral involved in cellular metabolism.
  • Excess of Vitamin A.

6. Endocrine Problems:

In some children, the cause of hair loss is hypothyroidism, a condition in which the thyroid is underactive and produces an insufficient amount of metabolism-regulating hormones. Proper pediatric guidance must be sought for the same.


For all medical conditions, the best solution is prompt medical attention. Consult your pediatrician and a specialist dermatologist. For children undergoing cancer treatments, baldness is due to exposure to chemotherapy and radiation. The baldness will give way to renewed hair growth.
For other non-medical causes the following is the best solution:
  • A balanced nutritional diet
  • Regular hair care to keep the scalp clean and healthy
  • Avoiding harsh chemical treatments

Coping with Hair Loss:

If your child has the aforementioned conditions, then realise that it is an emotionally difficult time for him/her. In addition to loss of self-confidence, they can ridiculed or bullied due to their baldness or thinning hair. Get prompt treatment. Don’t ignore the psychological and emotional aspects. Acknowledge and validate their feelings. Help them work through their emotions.
