Hair loss
Overview of Hair loss
On average, individuals shed about 50 to 100 strands of hair daily as part of the natural hair cycle, where old hair falls out while new growth takes its place. However, when this balance is disrupted, and hair loss outpaces regrowth, it results in a condition known as alopecia.
Hair loss can affect both men and women, as well as, in some cases, children. It may present as thinning hair, a receding hairline, widening of the part, or bald patches. Various factors contribute to hair loss, including genetics, aging, hormonal imbalances, nutritional deficiencies, medical conditions, and certain medications. Additionally, frequent use of tight hairstyles, excessive styling products, stress, and chemical treatments may also accelerate hair fall.
Though hair loss does not directly impact physical health, its psychological effects can be significant. Hair plays a crucial role in self-image and confidence, and excessive hair loss can lead to emotional distress. Fortunately, there are multiple treatment approaches to address this concern.
Many individuals begin with home remedies or oral hair supplements to manage hair fall. However, consulting a dermatologist or trichologist is recommended for a proper diagnosis and treatment plan. Treatment options may include topical applications such as Minoxidil, oral medications, Platelet-Rich Plasma (PRP) therapy, steroid injections, and hair transplantation.

Symptoms Of Hair loss
The signs of hair loss can vary widely. Some individuals experience gradual thinning, while others may notice sudden hair shedding. Common symptoms include:
- Gradual thinning on the scalp—a common occurrence with age.
- Receding hairline (frontal fibrosing alopecia)—the forehead appears higher as the hairline moves back.
- Widening part—people who part their hair may observe the parting becoming broader over time.
- Circular bald patches—some individuals develop bald patches on the scalp, eyebrows, or beard.
- Increased hair shedding—excessive hair may fall out while combing or washing.
- Decreasing ponytail thickness—hair may appear less voluminous.
- Scalp visibility—as hair thins, the scalp may become more noticeable.
- Full-body hair loss—some medical treatments, like chemotherapy, can cause total hair loss.
Hair loss may be gradual or sudden:
- Gradual hair thinning is more common and occurs over time, with symptoms such as a widening part or receding hairline.
- Sudden hair loss can be more severe, resulting in large clumps falling out in a short period, sometimes leading to bald spots.
Additional Symptoms Associated with Hair Loss
In some cases, hair loss may be accompanied by other scalp-related symptoms:
- Itching and redness—may indicate an underlying infection.
- Scaly patches with sores—could suggest fungal infections like ringworm or chronic skin conditions such as psoriasis.
- Burning or tingling sensations—some individuals with alopecia areata may experience discomfort before hair shedding.
- Pus-filled sores—infections like folliculitis can cause inflamed, pus-filled lesions, resulting in temporary hair loss.
Hair loss can be distressing, but early diagnosis and proper treatment can help manage the condition effectively.
Triggering Factors Of Hair loss
To understand hair loss better, it is essential to know how hair growth works. Hair follicles undergo a three-phase cycle:
Anagen Phase (Growth Phase):
- This is the active phase, lasting between two and six years.
- Around 85-90% of the hair on the scalp is in this stage at any given time.
Catagen Phase (Transition Phase):
- A brief phase lasting approximately 2-3 weeks.
- Only about 1% of hair is in this stage.
Telogen Phase (Resting Phase):
- This marks the end of the hair growth cycle.
- Roughly 13% of the hair is in this phase, after which shedding occurs, and new hair begins to grow.
Hair growth is influenced by multiple factors such as age, medical conditions, dietary habits, and hair care practices.
Common Causes of Hair Loss:
- Aging: Hair naturally thins as people age, leading to a receding hairline and decreased hair density.
- Genetics: Hereditary factors are the most prevalent cause of hair loss, known as androgenic alopecia or pattern baldness. It appears as bald spots or receding hairlines in men and hair thinning along the crown in women.
- Postpartum and Stress-Related Hair Loss: Hormonal shifts following childbirth, chronic illnesses, or significant emotional stress can contribute to excessive hair shedding.
- Medications & Treatments: Certain medications for cancer, arthritis, heart disease, depression, high blood pressure, and gout can trigger hair loss, often within weeks of starting the treatment.
- Tight Hairstyles: Consistently wearing tight hairstyles, such as braids or ponytails, may cause traction alopecia, a form of permanent hair loss.
- Scalp Infections: Fungal infections, characterized by inflammation and scaling, can lead to hair shedding.
- Hormonal Imbalances: Conditions like polycystic ovary syndrome (PCOS) and the use of hormonal contraceptives can disrupt hair growth patterns, leading to thinning.
- Nutritional Deficiencies: Lack of essential nutrients, particularly protein, biotin, zinc, and iron, can result in hair thinning.
- Underlying Diseases: Medical conditions such as thyroid disorders, diabetes, lupus, and certain sexually transmitted infections (STIs) can contribute to hair fall.
- Trichotillomania: This psychological disorder involves compulsive hair pulling, which may result in permanent hair thinning over time.
Types Of Hair loss
Hair loss, also referred to as alopecia, is broadly categorized into cicatricial (scarring) and non-cicatricial (non-scarring) forms. Non-cicatricial alopecia involves reversible hair loss, whereas cicatricial alopecia results in permanent hair loss due to follicle destruction accompanied by scarring. Below are some common types of hair loss:
1. Non-Cicatricial (Non-Scarring) Alopecia
Androgenic Alopecia: Commonly known as hereditary hair loss, androgenic alopecia manifests differently in men and women. In men, it is termed male pattern baldness and is characterized by gradual hair thinning at the temples and crown, forming an ‘M’ shape. In women, it is known as female pattern baldness, leading to overall thinning of the scalp or a widening hair part.
Alopecia Areata: This autoimmune condition causes the immune system to attack hair follicles, leading to patchy hair loss on the scalp, face, or body. When it affects only certain areas, it is called alopecia areata. If hair loss occurs across the entire scalp, it is known as alopecia totalis, while complete body hair loss is termed alopecia universalis. The latter is often linked to conditions such as vitiligo and thyroid disorders.
Anagen Effluvium: This condition results in rapid and widespread hair loss, primarily triggered by radiation or chemotherapy treatments. Hair regrowth typically resumes after the treatment concludes.
Telogen Effluvium: A sudden, widespread shedding of hair often occurs following a period of emotional distress, illness, medication intake, or hormonal fluctuations such as those experienced during pregnancy, childbirth, menopause, or after starting or discontinuing birth control pills.
Traction Alopecia: Excessive strain on hair due to tight hairstyles like braids, ponytails, or buns can lead to this form of hair loss.
Trichotillomania: A psychological disorder where individuals compulsively pull out their own hair, leading to irregular bald patches and uneven hair length. This condition is more commonly observed in children and adolescents, with younger children often overcoming the habit naturally, whereas older individuals may require psychiatric intervention.
2. Cicatricial (Scarring) Alopecia
Cicatricial alopecia refers to a collection of rare inflammatory disorders that cause irreversible hair follicle destruction, leading to permanent hair loss. This type of alopecia can result from fungal infections, chemical exposure (such as hair relaxers), or inflammatory conditions, including discoid lupus erythematosus, lichen planopilaris, dissecting cellulitis, tufted folliculitis, folliculitis decalvans, alopecia mucinosa, alopecia neoplastica, central centrifugal cicatricial alopecia, and acne keloidalis.
Potential Risks for Hair loss
Numerous factors contribute to hair loss, some of which are preventable, while others are beyond control. Below are common risk factors:
- Genetics: A family history of hair loss significantly increases the likelihood of experiencing it.
- Stress: Chronic stress negatively impacts the body and can lead to hair shedding.
- Hormonal Changes: Fluctuations in hormone levels due to pregnancy, childbirth, menopause, or hormonal contraceptive use can elevate the risk of hair loss.
- Medications: Certain drugs may contribute to hair thinning. If hair loss occurs after starting a medication, consulting a doctor is advisable.
- Chemotherapy: Cancer treatments frequently result in temporary hair loss, with regrowth typically occurring post-treatment.
- Significant Weight Loss: Rapid or extreme weight loss can lead to hair shedding.
- Medical Conditions: Underlying health issues such as hypothyroidism, hyperthyroidism, diabetes, lupus, and sexually transmitted infections (STDs) may contribute to hair loss.
Diagnosis Of Hair loss
Diagnosing hair loss involves a thorough medical history assessment, physical examination, and specific diagnostic tests, including fungal screenings, hair pull tests, and microscopic evaluations.
Pull Test:
Also called the traction test, this procedure involves grasping 20-60 strands of hair between the thumb and fingers and gently pulling them. If more than 10% of the hair comes out, it indicates active hair shedding.
Light Microscopic Examination:
Hair strands collected from the pull test are examined under a microscope to detect irregularities, fractures, or coiling.
Scalp Biopsy:
A scalp biopsy is conducted when diagnosing scarring alopecia or unclear cases of non-scarring hair loss.
Blood Tests:
Blood work may be recommended to check for underlying conditions contributing to hair loss. Some key tests include:
- Iron Levels: Iron deficiency, particularly in pre-menopausal women, is a major cause of hair loss as it impairs oxygen and nutrient delivery to hair follicles.
- Zinc Levels: A lack of zinc can contribute to hair thinning and reduced hair growth.
- Biotin Levels: Also known as Vitamin B7, biotin is essential for keratin production and hair follicle growth. A deficiency may lead to hair thinning and loss.
Preventive Measures Of Hair loss
If you are experiencing hair loss, making certain adjustments to your hair care routine and incorporating a few simple habits can help reduce the problem. Consider the following tips:
- Minimize the use of heat styling tools such as curling irons, hot rollers, and hot oil treatments, as excessive heat can weaken hair strands and lead to breakage.
- Avoid tight hairstyles and excessive twisting, pulling, or rubbing of hair. Instead of rubbing wet hair with a towel, gently wrap it to absorb excess moisture and let it air dry naturally.
- Refrain from aggressive combing, which can cause split ends and hair damage. Opt for a wide-toothed comb to detangle hair gently.
- Regular oiling can help protect hair follicles from dirt and toxins. Additionally, a gentle scalp massage can enhance blood circulation, promoting healthier hair growth.
- Maintain a well-balanced diet rich in essential nutrients such as vitamins, minerals, and antioxidants—especially iron, biotin, and zinc—along with proteins, fats, and carbohydrates to support hair health.
- Avoid crash diets, as extreme calorie restriction can deprive hair follicles of vital nutrients, leading to increased shedding.
- Quit smoking, as it accelerates the aging of hair cells and weakens hair follicles, making them prone to breakage.
- Manage stress effectively, as chronic stress can cause hormonal imbalances that contribute to hair loss.
- Seek professional guidance from a trichologist or dermatologist to identify the underlying cause of hair loss and receive appropriate treatment. Avoid self-medicating with supplements or hair care products without expert advice.
Specialists to Consult
Hair loss may result from underlying health conditions such as nutritional deficiencies, PCOS, thyroid disorders, or anemia. It is advisable to consult a general physician to discuss hair loss concerns. Additionally, the following specialists can assist in diagnosis and treatment:
- Dermatologist
- Trichologist
Treatment Of Hair loss
A variety of treatment approaches are available to manage hair loss, ranging from medications to advanced procedures. These include:
A. Medications
Oral Supplements
- Vitamin B12 (Cobalamin): Essential for red blood cell production, which supplies oxygen and nutrients to hair follicles, promoting healthy growth.
- Vitamin B7 (Biotin): Stimulates keratin production and enhances follicle growth, particularly beneficial for those with a deficiency.
- Zinc: Plays a crucial role in protein synthesis necessary for hair growth.
- Iron: Boosting iron levels can effectively address hair loss caused by ferritin deficiency. Iron-rich foods and supplements can help restore hair health.
Minoxidil
- An FDA-approved topical treatment for both men and women. The 5% concentration is recommended for male pattern baldness, while 2% is approved for female pattern baldness. Minoxidil helps slow hair thinning and stimulates new hair growth.
Finasteride
- A prescription medication approved for men, primarily used to treat hair loss by inhibiting the hormone DHT, which contributes to male pattern baldness.
Topical Corticosteroids or Steroid Injections
- These treatments help reduce inflammation and stimulate hair regrowth. Administered as topical creams or scalp injections, they are typically given every 4 to 8 weeks as needed. Consult a dermatologist for suitability.
B. Platelet-Rich Plasma (PRP) Therapy
PRP therapy involves drawing the patient's blood, processing it to concentrate growth factors, and injecting it into the scalp to stimulate hair growth. The process includes:
- Blood is drawn from the arm and placed in a centrifuge to separate components.
- After centrifugation, the blood is divided into three layers: platelet-poor plasma, platelet-rich plasma, and red blood cells.
- The scalp is numbed, and platelet-rich plasma is injected into targeted areas to promote hair regrowth.
C. Hair Transplantation
A dermatologist or cosmetic surgeon transplants hair from a healthy area to a bald spot. Common techniques include:
- Follicular Unit Transplantation (FUT): A strip of scalp with hair is removed and transplanted to balding areas. Although effective, it leaves a scar and requires longer recovery.
- Follicular Unit Extraction (FUE): Individual hair follicles are extracted and transplanted, resulting in minimal scarring and quicker recovery.
Possible risks of hair transplantation include bleeding, swelling, and infection. Consult a dermatologist to determine the most suitable method.
D. Laser Treatment
Various laser devices, such as combs and brushes, claim to stimulate hair growth and reduce hair fall. However, their effectiveness and safety are not fully established. It is advisable to seek professional guidance before using such treatments.
Health Complications Of Hair loss
While hair loss or alopecia does not cause direct physical harm, it can take a toll on mental well-being. Anxiety, depression, and self-esteem issues are common psychological effects of hair loss, affecting both men and women. Additionally, increased stress levels can further exacerbate hair fall, creating a vicious cycle. When treatments fail to show results, it can further contribute to emotional distress.
Alternative Therapies For Hair loss
Aromatherapy
- Essential oils like sandalwood, rosemary, and thyme contain compounds that are believed to stimulate hair growth. Massaging these oils into the scalp for a few minutes each night may support hair regrowth.
Acupuncture
- Acupuncture has been linked to improved blood circulation in the scalp, which may reduce hair loss and support hair regrowth. However, further scientific research is needed to confirm its effectiveness.
Microneedling
- Microneedling involves using tiny needles to stimulate stem cells in the hair follicles, promoting hair growth. It may also enhance the absorption of hair loss treatments such as minoxidil, platelet-rich plasma (PRP), and topical steroids.
Homemade Remedies for Hair loss
Onion (Pyaaz) Juice
Rich in sulfur, onions play a crucial role in the formation of amino acids, proteins, and collagen—all essential for hair growth and preventing hair fall. Applying onion juice directly to the scalp enhances blood circulation to the hair follicles, which helps counteract hair thinning and promotes hair regrowth.
Eggs
Eggs are packed with hair-nourishing nutrients such as biotin, vitamin A, vitamin E, and folate. These nutrients work together to stimulate hair growth and prevent hair loss caused by dietary deficiencies.
Aloe Vera
This natural remedy helps soothe the scalp, condition dry hair, and minimize dandruff. Aloe vera also nourishes the hair follicles, promoting overall hair health when applied to the scalp and hair strands.
Coconut (Nariyal) Oil
Coconut oil enhances hair strength and shine, thanks to its lauric acid content, which deeply penetrates the hair shaft. Regular use as a pre- and post-wash treatment can help minimize protein loss in both damaged and healthy hair.
Fenugreek (Methi) Seeds
Fenugreek seeds are known to contain plant-based hormones (phytoestrogens) that have been linked to improved hair growth and reduced hair shedding.
Bhringraj
Bhringraj (Eclipta alba) is one of the most well-known Ayurvedic remedies for hair loss. Studies suggest that its methanolic extract can stimulate hair growth by extending the active growth phase (anagen phase) of hair follicles.
Tea Tree Oil
Tea tree oil is recognized for its cleansing, antimicrobial, and anti-inflammatory properties. When applied topically, it can help unclog hair follicles, improve nutrient absorption, and encourage hair regrowth.
Lifestyle Modifications Hair loss
Experiencing hair loss can be emotionally challenging, as hair is often tied to personal identity and confidence. If you notice signs of thinning hair, you don’t have to accept it passively—exploring various treatment options can help. However, if treatments prove ineffective, there are other ways to cope with hair loss:
Wear Scarves or Bandanas
- A soft cotton or silk scarf can provide a stylish way to cover thinning hair while protecting the scalp from irritation.
Try Hair Extensions or Wigs
- For those experiencing partial or complete hair loss, hair extensions or wigs offer an effective way to restore the appearance of fuller hair.
Wear Hats
- Hats provide another fashionable option to conceal hair loss, whether worn occasionally or as part of a daily routine.
Seek Counseling
- If hair loss affects your confidence or mental health, speaking with a counselor or therapist can be beneficial. Expressing your concerns can help you cope better with the emotional impact.
Join a Support Group
- Connecting with others who share similar experiences, either in-person or online, can offer comfort and encouragement during your hair loss journey.
Embrace Baldness
- While not for everyone, some people choose to embrace their baldness with confidence, viewing it as a symbol of self-acceptance rather than something to hide.
