Understanding Hair Loss in Patches: Causes, Treatment, and Prevention

Hair loss in patches, medically known as alopecia areata, is a condition that affects millions of individuals worldwide. It manifests as sudden, isolated hair loss in circular or oval patches, often causing distress and concern among those affected. Understanding this condition’s causes, treatment options, and prevention strategies is crucial in helping individuals manage and cope with hair loss’s emotional and physical impact. 

This TH Cosmetic‘s article will delve into the factors contributing to alopecia areata, explore the available treatments, and discuss preventive measures to promote healthy hair growth and overall well-being.

Types of Hair Loss

Here are the details about the types of hair loss you mentioned:

Androgenetic Alopecia (Male/Female Pattern Baldness)

Androgenetic alopecia is the most common type of hair loss, affecting both men and women. It is often referred to as male pattern baldness in men and female pattern baldness in women. Genetic and hormonal factors influence this condition.

In men, it typically starts with a receding hairline and thinning at the crown, while in women, it causes diffuse thinning over the top of the scalp. Androgenetic alopecia is linked to the hormone dihydrotestosterone (DHT), which causes hair follicles to shrink over time, leading to shorter and finer hair until they stop producing hair altogether.

Alopecia Areata

Alopecia areata is an autoimmune disorder in which the immune system mistakenly attacks hair follicles, leading to sudden hair loss.

This condition can occur in patches on the scalp or other body parts, such as eyebrows, eyelashes, and beard. The bald patches are usually smooth and round, and the underlying skin is unscarred. Hair may regrow independently in some cases, but the condition can be unpredictable, and hair loss may recur.

Traction Alopecia

Traction alopecia is a form of hair loss caused by repetitive and excessive pulling or tension on the hair. It often results from hairstyles that stress the hair follicles, such as tight ponytails, braids, buns, and hair extensions. Over time, this constant pulling can weaken hair follicles, causing breakage and permanent hair loss in the affected areas.

Telogen Effluvium

Telogen effluvium is a temporary type of hair loss that occurs when many hair follicles prematurely enter the hair growth cycle’s resting phase (telogen). Various factors can trigger this, including physical or emotional stress, illness, hormonal changes, rapid weight loss, certain medications, and nutritional deficiencies. The shedding typically becomes noticeable a few months after the triggering event, and in most cases, the hair regrows once the underlying cause is addressed.

Trichotillomania

Trichotillomania is a psychological disorder characterized by an irresistible urge to pull out one’s hair, including scalp hair, eyebrows, eyelashes, and other body hair. People with trichotillomania often experience tension or anxiety before pulling, followed by relief or gratification. The repetitive pulling can lead to noticeable hair loss, and in severe cases, it can cause bald patches. Behavioral therapy and other forms of psychological intervention are often used to treat trichotillomania.

Causes of Hair Loss in Patches

Hair loss in patches can be a distressing experience for those affected, and understanding the potential causes is crucial to finding appropriate treatment and management strategies. Here are some of the main causes of hair loss in patches:

Genetics and Family History

A significant factor in alopecia areata is a person’s genetic predisposition. If you have a family history of hair loss, especially in patches, you may be more susceptible to developing the condition. Researchers have identified certain genetic markers associated with this condition, which can increase the likelihood of its occurrence in some individuals.

Autoimmune Disorders

One of the primary causes of hair loss in patches is an autoimmune response, where the body’s immune system mistakenly attacks its hair follicles. In alopecia areata, the immune cells target the hair follicles, causing inflammation and subsequent hair loss. The exact reasons behind this autoimmune response are not yet fully understood, but it is believed to be a combination of genetic and environmental factors.

Hormonal Imbalances

Hormonal fluctuations can play a role in hair loss. Polycystic ovary syndrome (PCOS) or thyroid disorders can lead to hormonal imbalances, affecting hair growth patterns. Androgenetic alopecia, commonly known as male or female pattern baldness, is also related to hormonal changes and can sometimes manifest as patchy hair loss.

Stress and Anxiety

High stress and anxiety levels can contribute to various health issues, including hair loss. Stress-related hair loss, known as telogen effluvium, can lead to patches of thinning hair on the scalp. Additionally, the stress-induced release of certain hormones can disrupt the hair growth cycle, causing hair to fall in clumps or patches.

Hairstyling Practices

Certain hairstyling practices, particularly those that pull the hair tightly or involve harsh chemicals, can damage hair follicles and lead to hair loss. Conditions like traction alopecia can result from tight hairstyles such as braids, ponytails, or extensions, causing hair to break or fall out in localized areas.

Medical Conditions and Treatments

Various medical conditions and treatments can trigger hair loss in patches. For instance, cancer treatments like chemotherapy can cause temporary hair loss; in some cases, hair may regrow patchily. Skin conditions like scalp infections or lichen planus can also lead to localized hair loss.

Recognizing Hair Loss in Patches

Hair loss in patches is a condition where hair falls out in distinct areas, leaving bald patches on the scalp. Identifying this condition early is crucial for effective treatment. Here are some details on recognizing hair loss in patches:

Identifying the Early Signs

Early detection of hair loss in patches can improve the chances of successful treatment. Act promptly if you notice any of the following early signs:

• Small Bald Patches: Alopecia areata usually begins with small, round, or oval-shaped bald patches. These patches may vary and can be as small as a coin or larger.
• Well-defined Borders: The bald patches typically have distinct and well-defined borders. The skin within the patch is usually smooth and devoid of hair.
• No Scaling or Inflammation: Unlike other scalp conditions, alopecia areata does not cause scaling, redness, or significant inflammation in the affected areas.
• Regrowth at the Edges: You might notice some fine, white hairs at the edges of the bald patches. This indicates that the hair follicles are still active and have the potential for regrowth.
• Multiple Patches: Alopecia areata can affect more than one area on the scalp or even spread to other body parts with hair, such as the eyebrows, beard, or limbs.

Consulting a Dermatologist

If you suspect hair loss in patches or notice any of the early signs mentioned above, it’s essential to seek the expertise of a dermatologist or a hair specialist. A professional evaluation is crucial to confirm the diagnosis and rule out other potential causes of hair loss.

During the consultation, the dermatologist will:

• Review Medical History: The dermatologist will inquire about your medical history, family history of hair loss, and any other relevant information.
• Examine Scalp and Hair: A thorough examination of your scalp and hair will be conducted to assess the extent and pattern of hair loss.
• Ask about Symptoms: Be prepared to discuss any itching, pain, or changes in the affected areas.
• Recommend Tests: In some cases, the dermatologist may perform a scalp biopsy or suggest blood tests to help with the diagnosis.
• Suggest Treatment Options: The dermatologist will recommend appropriate treatment options tailored to your specific condition and needs based on the diagnosis.

Diagnostic Procedures

Physical Examination

The initial step in diagnosing hair loss in a patch involves a thorough physical examination by a qualified healthcare professional, such as a dermatologist or a trichologist. During this examination, the specialist will inspect the affected area of the scalp for any visible signs of hair loss.

They will look for specific characteristics, including the size and shape of the patch, the presence of broken or miniaturized hairs, inflammation, scaling, and redness. The healthcare professional will also assess the overall health of your hair and scalp to rule out any underlying conditions.

Scalp Biopsy

In cases where the cause of hair loss is not evident from the physical examination alone, a scalp biopsy may be recommended. A scalp biopsy involves the removal of a small tissue sample from the affected area of the scalp, usually under local anesthesia.

The collected sample is then sent to a laboratory for further analysis. The pathologist examines the tissue under a microscope to determine the underlying cause of hair loss, such as alopecia areata, scarring alopecia, or other skin conditions.

Trichoscopy

Trichoscopy, also known as dermatoscopy or scalp dermoscopy, is a non-invasive diagnostic procedure that allows a magnified examination of the scalp and hair follicles. A specialized handheld device with a magnifying lens and light source is used for this purpose.

Trichoscopy helps the healthcare professional to observe specific patterns and structures of the scalp and hair, providing valuable insights into the type and stage of hair loss. It can aid in distinguishing between different types of alopecia, identifying hair shaft abnormalities, and assessing hair follicle health.

Blood Tests

Blood tests are essential to identify systemic conditions or deficiencies contributing to hair loss. The healthcare professional may request various blood tests to check for conditions like thyroid disorders, iron deficiency (anemia), hormonal imbalances (e.g., androgenetic alopecia), vitamin D deficiency, and autoimmune diseases. These tests help rule out potential underlying medical issues that could trigger hair loss.

Treatment Options

Treatment options for hair loss in patchy areas (also known as alopecia areata) can vary depending on the severity of the condition and individual factors. Here are some detailed explanations of the treatment options available:

Topical Medications

• Corticosteroids: These are anti-inflammatory drugs that can be applied as creams, ointments, or lotions directly on the affected areas. They help to suppress the immune response responsible for attacking hair follicles in alopecia areata and promote hair regrowth.
• Minoxidil: This over-the-counter medication is available in various strengths as a liquid or foam. It is applied to the scalp and may stimulate hair growth by enhancing follicular blood flow.

Oral Medications

• Corticosteroids: In severe cases or when topical medications are ineffective, corticosteroids can be prescribed orally. They work by reducing inflammation and immune system activity attacking the hair follicles. However, long-term use of oral corticosteroids may have side effects and should be monitored by a healthcare professional.
• JAK Inhibitors: Janus kinase (JAK) inhibitors are a relatively new class of medications that have shown promising results in treating alopecia areata. These oral drugs target specific immune pathways involved in hair loss.

Injections and Immunotherapy

• Intralesional Corticosteroid Injections: A dermatologist injects corticosteroids directly into the affected patches to reduce inflammation and promote hair regrowth.
• Topical Immunotherapy: Chemicals like diphenylcyclopropenone (DPCP) or squaric acid dibutyl ester (SADBE) are applied to the scalp, creating allergic contact dermatitis. This stimulates an immune response that may help halt the attack on hair follicles and promote hair growth.

Laser Therapy

Low-Level Laser Therapy (LLLT): Also known as red light therapy or cold laser therapy, this non-invasive treatment involves using low-intensity lasers or light-emitting diodes (LEDs) to stimulate hair follicles, potentially promoting growth.

Hair Transplantation

• Follicular Unit Transplantation (FUT): This traditional method involves removing a strip of skin with healthy hair follicles from the donor area (usually the back of the head) and transplanting it into the balding or patchy areas.
• Follicular Unit Extraction (FUE): In this newer technique, individual hair follicles are extracted from the donor area and transplanted into the affected areas. It leaves minimal scarring and may suit patients who prefer shorter haircuts.
• Robotic Hair Transplantation: Advanced robotic systems can assist in the FUE procedure, improving precision and reducing procedural time.

Natural Remedies and Home Care

Essential Oils

Essential oils have been used for centuries for various health and beauty purposes, including promoting hair growth. Regarding hair loss in patches, some essential oils can help stimulate the hair follicles and encourage regrowth. Here are a few effective essential oils to consider:

• Rosemary Oil: Known for its hair-stimulating properties, rosemary oil can improve blood circulation in the scalp and promote hair growth. Mix a few drops of rosemary oil with a carrier oil (such as coconut or jojoba oil) and massage it gently onto the affected patch.
• Lavender Oil: Lavender oil has calming properties that can help reduce stress, a common factor in hair loss. It also supports a healthy scalp and may aid in regrowth. Combine lavender oil with carrier oil and apply it to the patch regularly.
• Peppermint Oil: Peppermint oil contains menthol, which can boost blood circulation and stimulate hair follicles. Dilute peppermint oil with carrier oil and gently massage it onto the patch.
• Cedarwood Oil: Cedarwood oil is believed to balance oil production, benefiting those with patchy hair loss caused by an overly oily scalp. Mix cedarwood oil with carrier oil and massage it into the scalp.

Aloe Vera Gel

Aloe vera is a well-known natural remedy for various skin and hair conditions, including hair loss. It has soothing and anti-inflammatory properties that help maintain a healthy scalp and promote hair regrowth in the affected area.

To use aloe vera gel for hair loss in patches, follow these steps:

• Cut open an aloe vera leaf and extract the gel.
• Apply the fresh gel directly to the affected patch on your scalp.
• Gently massage the gel into the skin and leave it on for at least 30 minutes.
• Rinse it off with lukewarm water.
• You can repeat this process two to three times a week for the best results.

Scalp Massage Techniques

Scalp massages are relaxing and stimulate blood circulation in the scalp, which, in turn, promotes hair growth. When massaging the patchy area, you enhance the delivery of essential nutrients to the hair follicles. Here’s how to perform a scalp massage:

• Sit or lie down comfortably, and use your fingertips to gently massage the affected patch on your scalp in circular motions.
• Apply slight pressure, but don’t be too forceful to avoid causing any additional hair damage.
• You can use your bare hands or add a few drops of essential oil or aloe vera gel to enhance the massage’s effectiveness.
• Perform the scalp massage for about 5 to 10 minutes a few times a week.
