🌺 Causes of Hair Loss (Excluding Medication)

Understanding the underlying causes of hair loss is crucial for developing effective prevention and treatment strategies. This comprehensive guide explores the various factors that can contribute to hair loss, including lifestyle, medical conditions, and genetics.

1. Stress

Stress is a significant contributor to hair loss. When the body experiences stress, it releases cortisol, a hormone that can disrupt the hair growth cycle and lead to increased hair shedding [1]. Stress-induced hair loss, known as telogen effluvium, typically occurs several months after a stressful event and can be triggered by both physical and emotional stressors [2].

Treatment: Managing stress is key to addressing stress-related hair loss. This may involve stress-reduction techniques, such as meditation, yoga, or cognitive-behavioral therapy. Ensuring adequate rest, maintaining a healthy lifestyle, and seeking support from mental health professionals can also be beneficial [8].

2. Nutrient Deficiencies

Deficiencies in essential nutrients can contribute to hair loss. Some key nutrients for healthy hair growth include [4]:

• Iron: Iron deficiency anemia can lead to hair loss.

• Zinc: Zinc plays a role in hair tissue growth and repair.

• Vitamin D: Low levels of vitamin D have been linked to hair loss.

• Protein: Inadequate protein intake can cause hair thinning and shedding.

Treatment: Treatment for nutrient-related hair loss involves correcting the underlying deficiency through dietary changes and supplementation. Consulting with a nutritionist can help identify specific nutrient gaps and develop a personalized plan to support healthy hair growth [6].

3. Childbirth

Many women experience increased hair shedding after giving birth. This condition, known as postpartum hair loss, is caused by hormonal changes that occur during pregnancy and after delivery. Postpartum hair loss is usually temporary and resolves within several months [5].

Treatment: In most cases, postpartum hair loss resolves on its own without treatment. Maintaining a healthy diet, managing stress, and using gentle hair care products can help support hair health during the postpartum period.

4. High Fever

A high fever can trigger hair loss. Febrile illnesses, such as severe infections or flu, can disrupt the hair growth cycle and cause increased hair shedding. This type of hair loss typically occurs a few months after the fever and is usually reversible [6].

Treatment: Hair loss caused by high fever usually resolves on its own once the underlying illness has been treated and the body has recovered. Maintaining good overall health and seeking prompt medical attention for febrile illnesses can help minimize the impact on hair health.

5. Surgery

Undergoing surgery can lead to hair loss. The physical stress of surgery, combined with the effects of anesthesia and post-operative recovery, can trigger telogen effluvium. Hair loss after surgery is usually temporary and resolves within a few months [7].

Treatment: Hair loss following surgery typically resolves on its own as the body recovers. Maintaining a healthy diet, managing stress, and following post-operative care instructions can support overall health and hair recovery.

6. Diet

A poor diet lacking in essential nutrients can contribute to hair loss. Crash diets, extreme calorie restriction, and rapid weight loss can also cause hair shedding. Maintaining a balanced diet rich in proteins, vitamins, and minerals is important for healthy hair growth [8].

Treatment: Consuming a balanced diet rich in essential vitamins and minerals, such as iron, vitamin D, zinc, and protein, can support healthy hair growth and prevent nutrient-related hair loss [17].

7. Hair Damage

Excessive hair styling and treatments can cause hair damage and breakage, leading to hair loss. Some common causes of hair damage include [9]:

• Heat styling (e.g., blow-drying, flat ironing, curling)

• Chemical treatments (e.g., hair dyes, bleaches, perms, relaxers)

• Tight hairstyles (e.g., ponytails, braids, buns)

• Harsh brushing or combing

Treatment: To prevent and treat hair loss related to styling practices, it is essential to avoid tight hairstyles, minimize the use of heat styling tools, and reduce the frequency of chemical treatments. Using gentle, nourishing hair care products and incorporating protective styles can help minimize damage [10].

8. Medical Conditions

Various medical conditions can cause hair loss, including [10]:

• Thyroid disorders (both hypothyroidism and hyperthyroidism)

• Autoimmune disorders (e.g., alopecia areata, lupus)

• Scalp infections (e.g., ringworm, folliculitis)

• Polycystic ovary syndrome (PCOS)

• Skin conditions (e.g., psoriasis, seborrheic dermatitis)

Treatment: Treatment for medical conditions that cause hair loss depends on the specific condition. This may involve medications, lifestyle changes, or other therapies as recommended by a healthcare professional.

9. Scalp Psoriasis

Scalp psoriasis is a chronic autoimmune condition that causes scaly, red patches on the scalp. The inflammation associated with scalp psoriasis can lead to hair loss in the affected areas. Treatment of scalp psoriasis often involves the use of medicated shampoos, topical corticosteroids, and other anti-inflammatory therapies [11].

Treatment: Treatment for scalp psoriasis may include medicated shampoos, topical corticosteroids, light therapy, and oral medications to manage symptoms and reduce inflammation [11].

10. Changes in Birth Control

Starting, stopping, or changing birth control medications can cause hormonal fluctuations that may trigger hair loss. The hormonal changes associated with birth control pills can disrupt the hair growth cycle and lead to increased hair shedding [12].

Treatment: If hair loss is related to changes in birth control, consulting with a healthcare provider can help determine the best course of action. This may involve adjusting the type of birth control, managing hormonal imbalances, or considering alternative contraceptive methods.

11. Hormones

Hormonal imbalances can contribute to hair loss in both men and women. In men, male pattern baldness (androgenetic alopecia) is caused by a sensitivity to dihydrotestosterone (DHT), a byproduct of testosterone [13]. In women, hormonal changes during menopause, pregnancy, and thyroid disorders can lead to hair thinning and shedding [14].

Treatment: Treatment for hormone-related hair loss depends on the specific hormonal imbalance. For male pattern baldness, treatments may include topical minoxidil, oral finasteride, or hair transplantation [2]. For women, hormone replacement therapy or medications that target specific hormonal imbalances may be recommended [4].

12. Thyroid Disease

Both hypothyroidism (an underactive thyroid) and hyperthyroidism (an overactive thyroid) can cause hair loss. Thyroid hormones play a crucial role in regulating hair growth, and imbalances can disrupt the hair growth cycle [15].

Treatment: Treatment for thyroid-related hair loss involves managing the underlying thyroid disorder. This may include medications to regulate thyroid hormone levels, such as levothyroxine for hypothyroidism or anti-thyroid drugs for hyperthyroidism.

13. Ageing

As we age, hair follicles naturally shrink and produce thinner, shorter, and less pigmented hair. This process, known as age-related hair thinning, is a normal part of the aging process and is influenced by genetic factors [16].

Treatment: While age-related hair changes are a natural part of the aging process, maintaining a healthy lifestyle, practicing gentle hair care, and using nourishing hair products can help minimize hair loss and promote healthier hair. In some cases, hair restoration treatments, such as minoxidil or hair transplantation, may be considered [16].

14. Infection

Certain infections of the scalp can lead to hair loss. Fungal infections, such as tinea capitis (ringworm of the scalp), can cause scaly patches and hair loss in the affected areas. Bacterial infections, such as folliculitis, can also cause inflammation and hair loss [17].

Treatment: Treatment for scalp infections depends on the specific type of infection. Antifungal medications, either topical or oral, are used to treat fungal infections like tinea capitis. Antibacterial medications, such as topical or oral antibiotics, may be prescribed for bacterial infections like folliculitis.

15. Genetics

Genetic factors play a significant role in hair loss. Male and female pattern baldness (androgenetic alopecia) is largely determined by genetic predisposition. Inherited hair loss tends to follow a predictable pattern and can be influenced by hormonal factors [18].

Treatment: Treatment options for genetic hair loss include topical minoxidil, oral finasteride (for men), low-level laser therapy, and hair transplantation [2]. While these treatments can help slow hair loss and promote hair growth, they cannot completely reverse genetic hair loss.

16. Pregnancy and Postpartum Changes

During pregnancy, increased levels of estrogen can prolong the hair growth phase, resulting in thicker, fuller hair. However, after delivery, estrogen levels drop, causing a significant number of hair follicles to enter the shedding phase (telogen effluvium). Postpartum hair loss is usually temporary and resolves within several months [19].

Treatment: In most cases, postpartum hair loss resolves on its own without treatment. Maintaining a healthy diet, managing stress, and using gentle hair care products can help support hair health during the postpartum period.

17. Weight Loss

Rapid weight loss, whether due to extreme dieting, bariatric surgery, or illness, can trigger hair loss. The physical and emotional stress associated with sudden weight loss can disrupt the hair growth cycle and cause increased hair shedding [20].

Treatment: To minimize hair loss related to weight loss, it is important to maintain a balanced diet, avoid extreme calorie restriction, and manage stress. If hair loss persists or is severe, consulting with a healthcare professional can help identify any underlying nutritional deficiencies or medical conditions that may be contributing to the problem.

18. Low Levels of Protein or Iron

Inadequate intake of protein and iron can contribute to hair loss. Protein is essential for hair structure and growth, while iron deficiency can lead to anemia, which is associated with hair thinning and shedding [21].

Treatment: Increasing dietary intake of protein and iron-rich foods can help prevent and treat hair loss related to these nutrient deficiencies. Good sources of protein include lean meats, poultry, fish, eggs, and plant-based sources like legumes and tofu. Iron-rich foods include red meat, poultry, fish, leafy green vegetables, and fortified cereals. In some cases, iron supplements may be recommended under the guidance of a healthcare professional.

19. Autoimmune Disorders (Alopecia Areata)

Alopecia areata is an autoimmune disorder in which the immune system mistakenly attacks hair follicles, leading to patchy hair loss on the scalp and other parts of the body. The exact cause is not fully understood, but genetic and environmental factors are thought to play a role [11].

Treatment: Treatment for alopecia areata may include corticosteroid injections, topical immunotherapy, or oral immunosuppressants to suppress the immune response and promote hair regrowth. In some cases, the hair may regrow spontaneously without treatment [12].

20. COVID 19

COVID-19, the disease caused by the SARS-CoV-2 virus, has been associated with various long-term effects, including hair loss. While the exact mechanisms are not fully understood, there are several potential ways in which COVID-19 may contribute to hair loss. Telogen effluvium, a type of hair loss triggered by a significant stressor, can occur when COVID-19 causes hair follicles to enter the resting phase prematurely, resulting in increased hair shedding a few months after the stressful event [35]. The systemic inflammatory response caused by COVID-19 may also disrupt the hair growth cycle and lead to hair loss [36]. Additionally, COVID-19 can cause a loss of taste and smell, leading to reduced food intake and potential nutritional deficiencies in nutrients like protein, iron, and zinc, which can contribute to hair loss [37]. Some medications used to treat COVID-19, such as antiviral agents and corticosteroids, may have hair loss as a side effect [38]. Furthermore, the psychological stress caused by the pandemic can exacerbate hair loss by disrupting the hair growth cycle and leading to increased hair shedding [39].

General Tips for Hair Loss Prevention and Treatment

1. Healthy Diet: Consume a balanced diet rich in essential vitamins and minerals, such as iron, vitamin D, zinc, and protein [17].

2. Proper Hair Care: Use gentle, sulfate-free hair products, minimize heat styling, and avoid tight hairstyles [18].

3. Manage Stress: Practice stress-reducing techniques like meditation, yoga, and regular exercise [19].

4. Regular Check-ups: Schedule regular check-ups with a healthcare provider to monitor overall health and identify any underlying conditions that could contribute to hair loss [20].

If you are experiencing significant hair loss, it is important to consult with a healthcare professional to determine the underlying cause and discuss appropriate treatment options.

Natural Alternatives for Alopecia and Hair Thinning

While conventional treatments for alopecia and hair thinning, such as medications and hair restoration surgery, can be effective, many people are interested in exploring natural alternatives. These alternative treatments aim to stimulate hair growth, improve scalp health, and provide a more holistic approach to managing hair loss. In this article, we will discuss several natural alternatives for alopecia and hair thinning, including Platelet-Rich Plasma (PRP) therapy, Platelet-Rich Fibrin (PRF) therapy, and microneedling.

1. Platelet-Rich Plasma (PRP) Therapy

Platelet-Rich Plasma (PRP) therapy is a non-surgical treatment that involves using a patient's own blood platelets to stimulate hair growth. The process involves drawing a small amount of blood from the patient, processing it to concentrate the platelets, and then injecting the platelet-rich plasma into the scalp. PRP contains growth factors that can promote hair follicle regeneration and improve the thickness and density of hair.

Several studies have shown promising results for PRP therapy in the treatment of androgenetic alopecia (male and female pattern baldness) and alopecia areata. A systematic review and meta-analysis by Giordano et al. (2017) found that PRP treatment significantly increased hair density and thickness compared to placebo or baseline values [22]. Another study by Alves and Grimalt (2018) demonstrated that PRP injections improved hair density, hair thickness, and hair growth in patients with androgenetic alopecia [23].

1. Platelet-Rich Fibrin (PRF) Therapy

Platelet-Rich Fibrin (PRF) therapy is a variation of PRP therapy that involves using a patient's own blood to create a fibrin matrix enriched with platelets and growth factors. The PRF matrix is then placed on the scalp to promote hair growth and improve scalp health. PRF therapy is believed to provide a more sustained release of growth factors compared to PRP, potentially leading to better results [24].

A study by Jha et al. (2018) compared the effectiveness of PRF and PRP in the treatment of androgenetic alopecia. The results showed that both treatments significantly improved hair density and thickness, but PRF was more effective than PRP in promoting hair growth [25]. Another study by Hausauer and Humphrey (2020) found that PRF injections improved hair density, hair thickness, and scalp health in patients with alopecia areata [26].

1. Microneedling

Microneedling, also known as collagen induction therapy, is a minimally invasive treatment that involves using a device with fine needles to create tiny punctures in the scalp. This process stimulates the body's natural healing response, promoting the production of collagen and growth factors, which can improve scalp health and hair growth [27].

A randomized controlled trial by Dhurat et al. (2013) compared the effectiveness of microneedling combined with minoxidil versus minoxidil alone in the treatment of androgenetic alopecia. The study found that the combination treatment resulted in significantly greater improvements in hair growth compared to minoxidil alone [28]. Another study by Fertig et al. (2018) demonstrated that microneedling improved hair density and thickness in patients with alopecia areata [29].

1. Other Natural Alternatives

In addition to PRP, PRF, and microneedling, several other natural alternatives have been explored for the treatment of alopecia and hair thinning. These include:

• Low-level laser therapy (LLLT): LLLT uses low-power lasers to stimulate hair follicles and promote hair growth [30].

• Scalp massage: Regular scalp massage can improve blood circulation and stimulate hair follicles, potentially promoting hair growth [31].

• Essential oils: Certain essential oils, such as peppermint, lavender, and rosemary, have been shown to improve hair growth and scalp health when used topically [32].

• Nutritional supplements: Supplements containing vitamins and minerals important for hair health, such as biotin, vitamin D, and iron, may help improve hair growth and thickness [33].

Hair loss is a complex condition with multiple contributing factors, including genetics, hormones, medical conditions, nutrition, stress, and lifestyle. While there is no one-size-fits-all solution, understanding the various causes and available treatment options can help individuals take proactive steps to maintain healthy hair and address concerns with the guidance of a healthcare professional.

It's important to remember that the most effective approach to managing hair loss depends on the underlying cause and individual circumstances. In some cases, lifestyle changes like improving diet, reducing stress, and optimizing hair care habits can help prevent or slow hair loss. In other cases, medical interventions such as medications, therapies, or hair restoration procedures may be necessary to achieve the desired results.

If you are experiencing persistent, severe, or distressing hair loss, it is essential to consult with a dermatologist or other qualified healthcare professional. They can help determine the underlying cause, recommend appropriate treatment options, and develop a personalized plan to help you achieve and maintain healthy hair.

While natural alternatives such as Platelet-Rich Plasma (PRP) therapy, Platelet-Rich Fibrin (PRF) therapy, and microneedling show promise in the treatment of alopecia and hair thinning, individual results may vary, and further research is needed to fully understand their effectiveness and long-term safety. It is always recommended to consult with a healthcare professional before starting any new treatment to determine the most suitable approach for your specific needs and medical history.
