13 Reasons Why Your Hair Is Falling Out

Hair loss is a common problem that affects millions of people around the world. It can be caused by various factors, such as genetics, hormones, stress, illness, medication, or environmental factors. In this article, we will explore 13 possible reasons why your hair is falling out and what you can do to prevent or treat it.

01 | Genetics

Genetic predisposition is a primary cause of hair loss, particularly in cases of male and female pattern baldness. This condition, also known as androgenetic alopecia, is characterized by a receding hairline, thinning crown, or widening part. It is influenced by the levels of hormones called androgens, which affect the growth cycle of hair follicles.

Hereditary hair loss with age is the most common cause of baldness. It can affect people as early as their teens or twenties, but it usually becomes more noticeable with advancing age. There is no cure for genetic hair loss, but there are treatments that can slow down or disguise the process, such as medications, topical solutions, hair transplants, or wigs.

02 | Hormonal Changes

Hormonal fluctuations, such as those during pregnancy, menopause, or thyroid disorders, can lead to temporary or permanent hair loss. These changes can affect the balance of estrogen and progesterone, which are important for hair growth and retention. They can also trigger an autoimmune response that causes inflammation and damage to the hair follicles.

Hormonal changes can cause excessive hair shedding, known as telogen effluvium. This condition occurs when large numbers of hair follicles enter the resting phase of the hair cycle and fall out two to three months after the triggering event. It typically does not lead to baldness, but it may cause noticeable thinning of the hair. Telogen effluvium usually resolves on its own within six months, but it may require treatment if it persists or recurs.

03 | Nutritional Deficiencies

A lack of essential nutrients, like iron, protein, and vitamins, can contribute to hair thinning. These nutrients are vital for the production of keratin, the main structural component of hair. They also support the health and function of the hair follicles and the blood vessels that supply them.

Nutritional deficiencies can cause hair loss by affecting the anagen phase of the hair cycle, which is the active growth phase. When the body does not have enough nutrients to support hair growth, it may divert them to more vital organs and systems. This can result in shorter or weaker hairs that are more prone to breakage or shedding. Nutritional deficiencies can be prevented or corrected by eating a balanced diet that includes foods rich in iron, protein, zinc, biotin, and other vitamins and minerals.

04 | Stress

Physical and emotional stress can trigger temporary hair loss, known as telogen effluvium. Stress can cause hormonal imbalances, inflammation, oxidative damage, and immune system dysregulation that can affect the health and growth of hair follicles. Stress can also induce a condition called trichotillomania , which is a compulsive urge to pull out one’s own hair.

Stress-induced hair loss usually improves three to six months after the stressful event is over or resolved. However, chronic stress can have a lasting impact on the hair cycle and lead to persistent or recurrent hair loss. Stress management techniques such as meditation, exercise, counseling, or relaxation therapies can help reduce stress levels and improve hair health.

05 | Hairstyling and Treatments

Excessive styling, heat treatments, and harsh chemicals can weaken hair and cause breakage. This type of hair loss is usually temporary and reversible, but it can also lead to permanent damage if not addressed. Some examples of hairstyling and treatments that can cause hair loss are:

  • Tight hairstyles, such as braids, ponytails, or buns, that pull on the scalp and create tension on the hair follicles
  • Heat tools, such as blow dryers, curling irons, or flat irons, that dry out and damage the hair shafts
  • Chemical treatments, such as bleaching, coloring, perming, or relaxing, that alter the structure and integrity of the hair

To prevent or reduce hair loss from hairstyling and treatments, you should:

  • Avoid or limit the use of heat tools and chemical treatments
  • Use gentle products that are suitable for your hair type and condition
  • Moisturize and condition your hair regularly to keep it hydrated and healthy
  • Choose loose hairstyles that do not pull on your scalp or hair
  • Trim your hair every few weeks to get rid of split ends and promote growth

06 | Medications and Treatments

Certain medications and treatments can cause hair loss as a side effect. This type of hair loss is usually temporary and reversible once the medication or treatment is stopped or changed. However, some medications and treatments can cause permanent hair loss in some cases. Some examples of medications and treatments that can cause hair loss are:

  • Chemotherapy and radiation therapy for cancer, which target rapidly dividing cells, including hair follicles
  • Blood thinners, such as warfarin or heparin, which interfere with blood clotting and may affect hair growth
  • Blood pressure drugs, such as beta-blockers or angiotensin-converting enzyme (ACE) inhibitors, which lower blood pressure and may reduce blood flow to the scalp
  • Hormonal drugs, such as birth control pills or hormone replacement therapy (HRT), which alter the balance of hormones in the body and may affect hair growth
  • Antidepressants, such as fluoxetine or sertraline, which affect the levels of neurotransmitters in the brain and may affect hair growth

To prevent or reduce hair loss from medications and treatments, you should:

  • Consult with your doctor before starting or stopping any medication or treatment
  • Ask your doctor about the possible side effects of your medication or treatment and how to manage them
  • Ask your doctor if there are any alternative medications or treatments that are less likely to cause hair loss
  • Take good care of your scalp and hair by washing them gently with mild shampoo and conditioner
  • Use a soft towel or a cotton t-shirt to dry your hair gently
  • Avoid brushing or combing your hair when it is wet or fragile

07 | Scalp Infections

Fungal infections, such as ringworm (tinea capitis), can lead to scaly patches and hair loss on the scalp. Ringworm is a contagious infection that can be spread by direct contact with infected people, animals, or objects. It can also be spread by sharing personal items, such as combs, brushes, hats, or towels. Ringworm can affect anyone, but it is more common in children.

Ringworm causes circular or oval patches of redness, scaling, itching, and baldness on the scalp. The patches may have a black dot pattern at the center where the hairs have broken off. The patches may also ooze fluid or pus.

To prevent or treat ringworm on the scalp, you should:

  • See a doctor for diagnosis and treatment
  • Take antifungal medication as prescribed by your doctor
  • Wash your scalp and hair daily with antifungal shampoo
  • Keep your scalp dry and clean
  • Avoid scratching or picking at the infected areas
  • Wash your hands frequently and avoid touching the infected areas
  • Do not share personal items with others
  • Disinfect your combs, brushes, hats, towels, and bedding

08 | Autoimmune Diseases

Autoimmune diseases are conditions where the immune system mistakenly attacks healthy cells in the body. One of the most common autoimmune diseases that causes hair loss is alopecia areata. Alopecia areata is a condition where the immune system attacks the hair follicles and causes them to stop producing hair.

Alopecia areata causes patchy baldness on the scalp or other parts of the body. The patches are usually round and smooth, and they may vary in size and number. The hair loss may be sudden or gradual, and it may be temporary or permanent. Alopecia areata can affect anyone, but it is more common in people with a family history of the condition or other autoimmune diseases.

To treat alopecia areata, you should:

  • See a doctor for diagnosis and treatment
  • Take corticosteroid injections, topical creams, or oral pills as prescribed by your doctor to suppress the immune system and stimulate hair growth
  • Use minoxidil (Rogaine) or other over-the-counter products to promote hair growth
  • Consider other treatments, such as light therapy, platelet-rich plasma (PRP) therapy, or hair transplantation, if your hair loss is severe or does not respond to other treatments
  • Wear a wig, hat, scarf, or other accessories to cover your bald spots and protect your scalp from sun exposure
  • Seek psychological support or counseling if your hair loss affects your self-esteem or mental health

09 | Aging

As we get older, our hair naturally becomes thinner and weaker. This is because the hair follicles shrink and produce less hair over time. According to Mayo Clinic, this type of hair loss, also known as androgenetic alopecia or male or female pattern baldness, is the most common cause of baldness. It usually affects the hairline and the crown of the head, but it can vary from person to person.

There is no cure for aging-related hair loss, but there are some treatments that can slow down or reverse its progression. These include medications such as minoxidil (Rogaine) and finasteride (Propecia), which stimulate hair growth and block the hormone that causes hair loss. Another option is hair transplantation, which involves moving healthy hair follicles from one part of the scalp to another.

10 | Harsh Hair Care Products

The products we use to wash, condition, style, and color our hair can also damage our hair and cause it to fall out. This is because some of these products contain harsh chemicals that can strip away the natural oils and proteins that protect our hair. Additionally, some of these products can cause allergic reactions or irritate the scalp, leading to inflammation and hair loss.

To prevent this type of hair loss, you should:

  • Choose gentle and natural hair care products that suit your hair type and scalp condition.
  • Avoid overwashing, overheating, or overstyling your hair, as these can weaken your hair and make it more prone to breakage. Instead, opt for mild shampoos and conditioners, use cool or lukewarm water, and limit the use of heat tools and chemical treatments.

11 | Environmental Factors

Another reason why your hair might be falling out is exposure to environmental factors such as pollution, UV rays, chlorine, salt water, and extreme temperatures. These factors can damage the outer layer of your hair, called the cuticle, and make it more brittle and dry. They can also affect your scalp health and interfere with blood circulation and nutrient delivery to your hair follicles.

To protect your hair from environmental damage, you should:

  • Wear a hat or a scarf when going outside, especially in sunny or windy weather.
  • Rinse your hair with fresh water after swimming in a pool or the ocean, and use a moisturizing conditioner or a leave-in treatment to hydrate your hair.
  • Eat a balanced diet rich in antioxidants, vitamins, minerals, and proteins that can nourish your hair from within.

12 | Excessive Smoking

Smoking is not only bad for your lungs and heart, but also for your hair. Smoking can damage the hair follicles and obstruct blood flow to the scalp, resulting in reduced oxygen and nutrient supply to your hair cells. According to Medical News Today, smoking can also increase the levels of hormones that cause hair loss, such as dihydrotestosterone (DHT) and cortisol.

The best way to prevent smoking-related hair loss is to quit smoking as soon as possible. Quitting smoking can improve your overall health and well-being, as well as your hair quality and quantity. If you need help quitting smoking, you can consult your doctor or a counselor for advice and support. You can also use nicotine replacement products such as patches, gums, or lozenges to ease your withdrawal symptoms.

13 | Overuse of Hair Accessories

Tight hairstyles and constant use of accessories can strain hair follicles and cause traction alopecia, a type of hair loss that occurs when the hair is pulled too hard for a long time. This can damage the hair roots and lead to permanent hair loss if not treated early. Some examples of hairstyles that can cause traction alopecia are braids, cornrows, ponytails, buns, and extensions.

To prevent traction alopecia, you should:

  • Avoid wearing tight hairstyles or accessories that pull on your hair.
  • Change your hairstyle frequently and let your hair loose at night.
  • Use gentle hair products and avoid heat-styling tools.
  • If you notice any signs of traction alopecia, such as receding hairline, bald patches, or inflammation, consult a dermatologist as soon as possible.
