Common Causes of Hair Loss
Understanding Hair Loss: Common Causes and What You Need to Know
Hair loss can stem from various factors, including genetic predispositions, hormonal fluctuations, lifestyle choices, and environmental influences. Let's delve into the common causes of hair loss, including the roles of microinflammation and oxidative stress.

Genetics (Androgenetic Alopecia)
Genetics plays a significant role in hair loss, particularly in androgenetic alopecia or male/female pattern baldness. In this condition, hair follicles become sensitive to hormones called androgens, leading to miniaturization of follicles and eventual hair thinning. Genetic factors determine the susceptibility of follicles to androgens.
Hormonal Imbalances
Hormonal changes can disrupt the hair growth cycle and contribute to hair loss. For instance, fluctuations in estrogen, progesterone, and testosterone levels during pregnancy, menopause, or thyroid disorders can impact hair growth. Hormonal imbalances can also trigger microinflammation in the scalp, affecting follicle health.
Medical Conditions and Inflammation
Certain medical conditions, such as autoimmune diseases (e.g., alopecia areata) and scalp conditions (e.g., seborrheic dermatitis), can cause inflammation in the scalp. This microinflammation can disrupt the normal hair growth cycle and lead to hair shedding or thinning. Addressing underlying medical issues is crucial for managing hair loss.
Nutritional Deficiencies and Oxidative Stress
Poor nutrition, particularly deficiencies in vitamins (e.g., vitamin D, vitamin B12) and minerals (e.g., iron, zinc), can contribute to hair loss. Additionally, oxidative stress caused by free radicals can damage hair follicles and impede hair growth. Antioxidants play a vital role in combating oxidative stress and promoting scalp health.
Stress and Lifestyle Factors
Chronic stress and unhealthy lifestyle habits can exacerbate hair loss. Stress hormones, such as cortisol, can disrupt the hair growth cycle and lead to increased shedding. Lifestyle factors like smoking, excessive alcohol consumption, and poor sleep quality can also impact hair health and contribute to oxidative stress.
Medications, Treatments, and Styling Practices
Certain medications, medical treatments (e.g., chemotherapy), and harsh hair styling practices (e.g., tight hairstyles, frequent use of heat styling tools) can damage hair follicles and lead to hair loss. It's essential to discuss potential side effects with healthcare providers and practice gentle hair care techniques.
Types of Hair Loss
Androgenetic Alopecia (Male and Female Pattern Baldness)
This is the most common type of hair loss, affecting both men and women. It is hereditary and usually results from a combination of genetic predisposition and hormonal factors. In men, androgenetic alopecia typically causes hairline recession and thinning at the crown, leading to a "M" shaped pattern of hair loss. Women with this condition often experience diffuse thinning all over the scalp.
Alopecia Areata
Alopecia areata is an autoimmune condition where the immune system mistakenly attacks hair follicles, causing hair loss in patches on the scalp, eyebrows, and other body hair. The hair loss in alopecia areata can be sudden and unpredictable, with round or oval patches of baldness. In some cases, the condition may progress to alopecia totalis (total scalp hair loss) or alopecia universalis (total body hair loss).
Telogen Effluvium
Telogen effluvium is a type of hair shedding that occurs due to a disruption in the normal hair growth cycle. It is often triggered by stressful events, hormonal changes, nutritional deficiencies, medications, or medical conditions. Individuals with telogen effluvium may notice increased hair shedding, usually a few months after the triggering event. The hair loss is temporary, and new hair growth typically resumes once the underlying cause is addressed.
Traction Alopecia
Traction alopecia is hair loss caused by repeated pulling or tension on the hair follicles. It is commonly seen in individuals who wear tight hairstyles (e.g., braids, ponytails, cornrows) or use hair extensions regularly. Traction alopecia typically results in hair loss along the hairline, temples, and areas where there is constant pulling or pressure on the hair.
Trichotillomania
Trichotillomania is a psychological disorder characterized by the urge to pull out one's hair, leading to noticeable hair loss and bald patches. Individuals with trichotillomania may exhibit repetitive hair pulling behaviours, often as a way to cope with stress, anxiety, or boredom. The hair pulling can result in uneven hair loss and damage to the hair follicles.
Cicatricial (Scarring) Alopecia
Cicatricial alopecia is a group of rare hair loss disorders characterized by inflammation and scarring of the hair follicles, leading to permanent hair loss. The hallmark of cicatricial alopecia is the presence of scar tissue in the affected areas of the scalp, which prevents hair regrowth. The hair loss patterns can vary depending on the specific subtype of cicatricial alopecia.
Scalp Conditions
Understanding Scalp Conditions
Scalp conditions can range from mild issues like dandruff to more severe conditions such as scalp psoriasis or eczema. For accurate diagnosis and effective treatment of scalp conditions, consult a dermatologist or healthcare provider. Here's a guide to common scalp conditions:

Dandruff
Dandruff is often caused by an overgrowth of yeast on the scalp, leading to flaking and itching.
Seborrheic Dermatitis
Seborrheic dermatitis is a chronic inflammatory condition characterized by red, flaky patches on the scalp.
Scalp Psoriasis
Psoriasis is an autoimmune condition that causes rapid skin cell turnover, leading to thick, scaly patches on the scalp.
Scalp Eczema (Atopic Dermatitis)
Scalp eczema is characterized by red, itchy, and inflamed patches on the scalp, often due to allergic reactions or skin sensitivity.
Scalp Infections (Fungal or Bacterial)
Fungal infections like ringworm or bacterial infections can cause scalp irritation, redness, and hair loss if left untreated.

Hair Loss Treatments
Hair loss can be a distressing issue, but several treatment options are available to help manage and improve hair growth. Here's a guide to common hair loss treatments:
Collapsible content
Topical Treatments
Minoxidil (Rogaine): Available over-the-counter, minoxidil is a topical solution or foam applied directly to the scalp. It can stimulate hair follicles, promote hair growth, and slow down hair loss. Results may vary, and continuous use is usually necessary to maintain benefits.
Oral Medications
- Finasteride (Propecia): This prescription medication is for men with male pattern baldness. It works by blocking the hormone DHT, which contributes to hair loss. Women should not use finasteride, especially if pregnant or planning pregnancy, due to potential risks to a developing male fetus.
- Spironolactone: Sometimes prescribed off-label for women with androgenetic alopecia, spironolactone is a diuretic medication that can also reduce androgen levels in the body, potentially slowing hair loss.
Hair Transplant Surgery
Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE): These surgical procedures involve transplanting hair follicles from donor areas (usually the back or sides of the scalp) to areas of thinning or baldness. Hair transplant surgery can provide natural-looking results, but it's essential to consult with a qualified surgeon.
Platelet-Rich Plasma (PRP) Therapy
PRP Injections involve extracting a small amount of your blood, processing it to concentrate platelets rich in growth factors, and injecting the PRP into the scalp. This treatment aims to stimulate hair follicles, promote hair growth, and improve hair thickness.
Natural topicals and Supplements
- Natural topical treatments: Quercetin, Rosemary oil, Saw Palmetto and Caffeine are believed to have hair growth-promoting properties as well as scalp relief. They can be applied topically through hair care products.
- B vitamin Hair Supplements: Biotin, Vitamin B3 and Vitamin B5 are often included in hair supplements or topical treatments. Consult with a healthcare professional before starting any supplements.
Consulting a Healthcare Professional
It's essential to consult with a dermatologist or hair specialist to determine the most suitable hair loss treatment for your specific condition. They can evaluate your hair loss pattern, medical history, and lifestyle factors to recommend personalized treatment options. Early intervention and consistent treatment adherence can lead to better outcomes in managing hair loss.
