Common Causes of Alopecia: How to Prevent Hair Loss?

Hair is often seen as a symbol of beauty, confidence, and vitality. However, millions of people around the world experience hair loss, a condition known as alopecia. The causes of the disorder can be numerous and varied, but understanding them is the first step toward prevention and effective medication. This guide covers the common causes of alopecia, the main types of this condition, methods for diagnosis and treatment, and natural tips on how to prevent hair loss. Whether you’re experiencing this health issue or want to safeguard your locks, this article provides valuable insights to help you maintain a healthy and luscious mane.

Another strategy into preventing hair loss is red light therapy. Red light therapy for hair growing is a safe and effective form of low-light laser therapy (LLLT) which can help you achieve more luxurious locks.

What is Alopecia (Hair Loss)?

Alopecia, commonly referred to as hair loss, is a prevalent and often emotionally distressing condition that affects both men and women of all ages, including teens. It may occur naturally or may be linked to a disease or the use of certain meds [1]. This condition involves the partial or complete loss of hair from areas where it typically grows, such as the scalp, eyebrows, and even the body.

While alopecia may manifest physically, its effects reach far beyond the surface. Hair is not merely a cluster of protein filaments; it is a critical component of your physical appearance that significantly influences your identity, self-esteem, self-image, and even cultural norms. The emotional impact of alopecia can’t be understated. For many, it transcends the physical realm, leading to a journey of self-discovery and self-acceptance.

Types of Alopecia: What Are the Common Causes of Hair Loss?

You may wonder what causes hair loss. Alopecia presents itself in various forms, each with distinct characteristics and underlying causes. Understanding these types and their common causes is essential for effectively addressing and preventing the condition. Below are the primary types of alopecia, shedding light on their origins and contributing factors.

Androgenic Alopecia

Androgenic alopecia, also known as male or female pattern baldness, is a prevalent form of alopecia primarily influenced by genetics and hormones. Genetics play a significant role, with a family history of this condition increasing the risk of developing it. Both sides of the family can contribute to this genetic predisposition, and specific patterns of alopecia are often inherited.

Hormones, particularly dihydrotestosterone (DHT), play a key role in androgenic alopecia, causing hair follicles to shrink and eventually cease producing hair. Age is another crucial factor, with the risk of this type of the disorder increasing as individuals grow older, typically becoming noticeable in the mid to late 20s and progressing, mostly affecting both females and male in old age. The interplay between genetic predisposition and age-related hormonal changes leads to gradual hair thinning and loss.

Telogen Effluvium

Telogen effluvium is a condition characterized by sudden and temporary hair shedding, and addressing its underlying causes is crucial for effective management. These causes encompass a wide range of factors, including severe stress triggered by emotional or physical turmoil, chronic diseases and severe infections diverting resources away from hair growth, hormonal changes during life events like pregnancy, menopause, or thyroid disorders.

Also, it may be caused by certain medications, particularly those used for cancer treatment or mental health, and the natural aging process, which may slow the hair growth cycle. The good news is that telogen effluvium is often reversible once the underlying cause is resolved, offering hope for those experiencing this type of the condition.

Alopecia Areata

Alopecia areata is an autoimmune disorder in which the immune system erroneously attacks hair follicles, causing alopecia in small, circular patches. Although the precise cause remains unclear, genetics and environmental factors are believed to be involved. Physical trauma, viral infections, and stress can act as triggers or exacerbate the condition. Allergies and high-stress levels may further worsen the disorder, while those with other autoimmune diseases have a heightened risk.

The complex interplay of these factors results in varying presentations of alopecia areata among individuals. Diagnosis and personalized treatment, typically under the guidance of a dermatologist or healthcare professional, are essential due to the unique experiences and treatment strategies that each case requires.

Anagen Effluvium

Anagen effluvium is often linked to exposure to aggressive cancer treatments like chemotherapy and radiation therapy, which are designed to target rapidly dividing cells, including hair follicles. This disruption in the normal hair growth cycle leads to sudden and severe alopecia, typically occurring within weeks of starting treatment.

Fortunately, anagen effluvium is often reversible, with hair regrowth expected once the body recovers from the effects of cancer treatment. This regrowth may take some time, but it’s a distinguishing feature of this alopecia type. Supportive measures, including gentle hair care, scalp care, and proper nutrition, can further help regrowth.

Furthermore, alopecia is a topic of concern among some modafinil users, with limited scientific data available on the link between modafinil and hair loss. A study by eHealthMe, as of August 5, 2023, indicated that 1.36% (228 of 16,746) individuals reported experiencing alopecia as a side effect of modafinil [3]. This side effect seemed more common among those who had been taking the drug for 5 to 10 years, particularly in the 50–59 age group, with a higher incidence among women. It’s important to note that the Food and Drug Administration (FDA) doesn’t list modafinil-induced alopecia as an official side effect.

Diagnosis and Treatment of Alopecia

Understanding the diagnosis and treatment of alopecia is pivotal in managing the condition, as each type necessitates distinct approaches. Diagnosis involves thorough medical history assessments, physical examinations, pull tests, scalp biopsies, blood tests, and microscopic examinations to pinpoint the type and causes of alopecia.

Treatment varies based on the specific type and underlying factors of the condition. For androgenic alopecia, treatments encompass topical minoxidil, oral finasteride, and hair transplants. Telogen effluvium management focuses on stress reduction, nutrition, and discontinuation of triggering medications. Alopecia areata can be addressed with corticosteroids, topical immunotherapy, or Janus kinase (JAK) inhibitors. Anagen effluvium, often chemotherapy-induced, typically reverses after treatment completion.

It’s essential to acknowledge that not all alopecia types are universally treatable, and patients may opt for self-acceptance or explore cosmetic solutions. Consulting a healthcare professional, preferably a dermatologist, ensures tailored care plans for optimal outcomes.

Best Natural Tips to Prevent Hair Loss

While there are various factors contributing to alopecia, incorporating natural strategies into your routine can help preserve and promote a healthy mane. Below are several valuable tips that, when followed diligently, can aid in reducing the risk of the disorder and maintaining a full, vibrant head of hair.

Seek Hair Loss Treatment As Soon As You Can

Early intervention is crucial in preventing alopecia from worsening. If you notice unusual hair thinning or shedding, consult a dermatologist or a hair specialist promptly. They can recommend the most appropriate course of action based on your specific condition. The sooner you address the issue, the better the chances of successful treatment.

Eat a Healthy Diet

A balanced diet rich in essential nutrients is vital for hair health. Hair is primarily composed of a protein called keratin, so consuming an adequate amount of protein is crucial. Additionally, vitamins and minerals, such as biotin, vitamins A and C, iron, and zinc, play a role in promoting hair growth. Incorporate foods like lean meats, fish, fruits, vegetables, and nuts into your diet to provide your body with the necessary nutrients.

Minimize Stress

Chronic stress is a significant contributor to alopecia. Stress triggers the release of hormones that can disrupt the hair growth cycle and lead to shedding. To minimize the impact of stress on your hair, practice stress management techniques such as meditation, yoga, deep breathing exercises, and regular physical activity. Getting sufficient sleep is also essential for managing stress.

Cut the Bad Habits

Certain habits, such as smoking and excessive alcohol consumption, can exacerbate the condition. Both of these behaviors can have a negative impact on circulation and overall health, including the health of your mane. Quitting or reducing these habits can benefit not only your hair but also your general well-being.

Take Supplements

Supplements can complement your diet and support hair health. Biotin, often referred to as the “hair vitamin,” is known for its positive impact on hair and nail growth. Iron and zinc are essential minerals for hair, and vitamin D may also play a role in hair growth. For instance, a 2014 study linked vitamin D deficiency to alopecia areata [4]. As a note, before adding supplements to your daily routine, consult a healthcare professional to determine which ones are appropriate for you and in what doses. Self-prescribing supplements can lead to adverse effects if not done carefully.

Get a Scalp Massage

Regular scalp massages can improve blood circulation to the hair follicles, promoting hair growth. You can use your fingertips to gently massage your scalp for a few minutes each day. This not only stimulates blood flow but also helps distribute natural oils produced by your scalp, keeping your hair healthy and moisturized.

Use Gentle Hair Care Products

Harsh hair care products can damage your mane and contribute to alopecia. Use mild, sulfate-free shampoos and conditioners that are suitable for your hair type. Avoid excessive heat styling and tight hairstyles that pull on the hair, causing breakage.

Stay Hydrated

Dehydration can affect hair health, making it more prone to breakage and shedding. Drinking an adequate amount of water ensures that your mane receives the moisture it needs to stay strong and healthy.

Do Regular Exercise

Regular exercise is beneficial for hair growth, as it increases blood circulation and oxygen in blood cells, which benefits follicles [5]. This can allow the growth phase of hair to be longer. Exercise can also reduce stress, which is one of the factors involved in hair thinning.

While the above-given tips contribute to hair health and potentially prevent alopecia, it’s essential to be patient and consistent in your efforts. Results may not be immediate, but with dedication, you can enjoy a healthy and vibrant mane.


Conclusively, alopecia can be emotionally challenging, but with the right knowledge and care, you can take steps to prevent the condition and maintain a healthy mane. Remember that individual experiences with alopecia can vary, and the effectiveness of treatments may differ from person to person. If you’re concerned about this health issue, don’t hesitate to seek professional guidance. By understanding the common causes of alopecia and following the natural tips provided in this guide, you can better protect your hair and boost your confidence.
