Understanding Hair Loss

Hair loss is one of those occurrences that becomes of increasing concern as we age, affecting both men and women. While some hair shedding is normal, excessive or sudden hair loss may indicate underlying health issues or lifestyle factors that could use adjusting. Understanding the potential causes can help in finding the right approach to manage and prevent further thinning.

Hair loss can be temporary or permanent, and its severity varies from mild thinning to complete baldness. Some cases are linked to genetics, whereas others may result from stress, medical conditions, hormonal imbalances, or even environmental influences. Consulting a healthcare professional can help determine the cause and appropriate management strategies.

Burst Health explores some of the most commonly asked questions surrounding hair loss and hair thinning.

How Much Hair is Normal to Lose Daily?

On average, it is normal to shed between 50 to 100 hairs per day. This shedding is part of the natural hair growth cycle, where old hairs fall out and new ones grow in their place. However, excessive hair loss beyond this range may indicate an issue such as hormonal changes, stress, or nutrient deficiencies.

If you notice increased shedding, bald patches, or thinning hair, it may be beneficial to seek professional advice to rule out any underlying health concerns.

Can Iron Deficiency Cause Hair Loss?

Yes, iron deficiency can contribute to hair thinning or excessive shedding. Iron plays a major role in producing hemoglobin, which carries oxygen throughout our bodies, including to our hair follicles. When iron levels are low, hair growth can slow down, and increased shedding may occur.

Symptoms of iron deficiency include fatigue, pale skin, brittle nails, and dizziness. A blood test can confirm whether low iron levels are contributing to hair loss, and appropriate dietary changes or supplements may help.

Can Stress Cause Hair Thinning or Loss?

Chronic stress can trigger a condition known as telogen effluvium, where a larger-than-normal percentage of hair follicles enter the resting phase, leading to increased shedding. Stress-related hair loss is often temporary, but persistent anxiety or emotional strain can prolong the problem.

Managing stress through mindfulness, exercise, and proper sleep can support hair regrowth and overall well-being.

Can Wearing a Hat Cause Hair Loss?

There is no scientific evidence that wearing a hat directly causes hair loss. However, wearing extremely tight headwear for prolonged periods may contribute to traction alopecia, a condition caused by repeated tension on the hair follicles.

To prevent unnecessary strain, choose well-fitted hats and try not to pull hair too tightly with accessories or hairstyles.

Can Smoking Cause Hair Loss?

Smoking has been linked to hair thinning due to its effects on circulation and oxygen delivery to hair follicles. The toxins in cigarettes can damage blood vessels, reducing the nutrients available to the scalp and impairing hair growth.

Can Dandruff Lead to Hair Loss?

Dandruff itself does not directly cause hair loss, but the irritation and inflammation associated with seborrhoeic dermatitis can weaken hair follicles. Constant scratching of an itchy scalp may also lead to breakage and increased shedding.

Using medicated shampoos and maintaining good scalp hygiene can help control dandruff and reduce hair loss caused by scalp inflammation.

Can Hair Dye Cause Thinning?

Frequent use of harsh hair dyes containing chemicals like ammonia and peroxide can weaken hair strands and lead to breakage. While dyeing does not affect hair follicles, excessive damage to the hair shaft can create the appearance of thinning.

Can Testosterone Levels Affect Hair Loss?

Yes, high levels of dihydrotestosterone (DHT), a byproduct of testosterone, can contribute to hair loss in individuals who are genetically predisposed to androgenetic alopecia (male or female pattern baldness). DHT binds to hair follicles, causing them to shrink over time and leading to progressive thinning.

On the other hand, low testosterone levels may also contribute to hair loss, though this is less common. Consulting a healthcare professional can help determine if hormonal imbalances are playing a role.

Can Radiotherapy Cause Hair Loss?

Yes, radiotherapy (radiation therapy) used to treat cancer can cause hair loss in the treated area. The severity of hair loss depends on the radiation dose and treatment location.

In some cases, hair regrows once treatment is completed, but regrowth may be thinner or different in texture. Supportive scalp treatments may help stimulate hair growth post-treatment.

Can Diabetes Cause Thinning Hair?

Diabetes can contribute to hair loss due to poor blood circulation and hormonal imbalances affecting hair follicle health. Uncontrolled blood sugar levels can also prolong the hair growth cycle, leading to excessive shedding.

Can Psoriasis Cause Hair Loss?

Psoriasis on the scalp can lead to temporary hair shedding due to inflammation, excessive scaling, and scratching. Severe cases can cause scarring, which may result in permanent hair loss if left untreated.

Medications and medicated shampoos prescribed by a healthcare professional can help control psoriasis and minimise hair loss.

Can Thyroid Problems Affect Hair Loss?

Yes, both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can cause hair thinning. The thyroid gland regulates hormones that influence hair growth, and any imbalance can disrupt the cycle, leading to hair shedding.

Can Steroids Cause Hair Loss?

Anabolic steroids, often used for muscle-building, can accelerate hair loss by increasing DHT levels, which shrink hair follicles.

On the other hand, corticosteroids, used for medical conditions, may cause temporary hair thinning as a side effect. If hair loss occurs after steroid use, consulting a healthcare professional is advised.

Can Creatine Cause Hair Loss?

There is limited scientific evidence linking creatine supplements to hair loss. Some studies suggest that creatine may increase DHT levels, which could contribute to hair thinning in individuals prone to male or female pattern baldness.

How Can I Prevent Hair Loss?

While some types of hair loss are genetic, several strategies can help maintain healthy hair:

• Maintain a balanced diet rich in protein, iron, and essential vitamins.

• Reduce stress through relaxation techniques and regular exercise.

• Avoid excessive heat styling and harsh chemicals that can damage hair.

• Use gentle hair care products suitable for your scalp type.

• Consult a professional if hair loss is sudden, severe, or persistent.

Is Hair Loss a Sign of Something Serious?

Hair loss can sometimes indicate underlying health issues such as:

• Nutritional deficiencies (e.g., iron, vitamin D, or protein).

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

• Hormonal imbalances (e.g., thyroid disorders, PCOS).

• Chronic illnesses (e.g., diabetes, severe infections).

If hair loss is accompanied by other symptoms like unexplained weight changes, fatigue, or skin rashes, seeking medical advice is recommended.
