Dandruff and Hair Loss: Unravelling the Connection

Dandruff and hair loss are among the two most concerning hair issues experienced by people worldwide. The connection between these conditions has been widely speculated. While there has not been any evidence to suggest that dandruff is a direct cause of hair loss, there is an indirect relation between the two.

This article discusses the causes of dandruff, its effect on hair health, and the best medical and natural treatments for dandruff.

Exploring the Causes of Dandruff

About 50% of the global population experiences dandruff at some point. This inflammatory condition turns the skin on the scalp dry and flaky, which falls off as white to yellowish flakes. Dandruff accompanies itchiness, which leads to scratching and damages the hair follicles. Understanding the cause is key to finding the appropriate dandruff solution. The common causes of dandruff are discussed below.

Malassezia Fungus Overgrowth

Malassezia is a fungus that naturally lives on the scalp. It survives by using the sebum produced there and releasing oleic acid.

Controlled numbers of this fungus do not harm the scalp. However, its overgrowth due to excess sebum or other conditions can lead to Malassezia infection, also called Malassezia folliculitis or Pityrosporum folliculitis. This fungus infects the hair follicles, causes breakouts, and triggers the growth of extra skin cells, which eventually form dandruff.

Seborrheic Dermatitis

Seborrheic dermatitis is an inflammatory scalp condition that causes scaling and flakiness. Dandruff is considered a milder form of this condition. It is often characterised by red and scaly rashes that appear darker than the surrounding skin. This condition leads to excess sebum production in the scalp, which, in turn, triggers the overgrowth of Malassezia fungus.

Genetic Factors

A common causative factor for dandruff is sensitivity to oleic acid, which can be inherited. As mentioned above, Malassezia produces oleic acid, and its overgrowth leads to a heightened production of this compound. Individuals who have inherited the gene for oleic acid sensitivity develop dandruff.

The Role of Itchy Scalp in Dandruff and Hair Loss

Itchy scalps can be caused by several factors, including dandruff, bacterial or fungal infection, or a buildup of dirt and dead cells. They have also been associated with hair loss and hair follicle damage. This section discusses the potential for hair loss due to dandruff and itchiness.

Understanding Scalp Itchiness

Scalp itchiness is often a symptom of scalp dryness, poor hygiene, or other conditions. Checking whether the itching sensation is accompanied by rashes, bumps, hair fall, or other symptoms can tell much about your hair and scalp health. This sensation urges one to scratch the scalp, leading to inflammation, irritation, and pain. Doctors can assess the nature and cause of the itch to understand the health status of your hair and take appropriate treatment measures.

Effects of Itchy Scalp on Hair Health

Itchiness can damage hair follicles and trigger hair fall. The irritation and inflammation caused by this sensation often trigger excess sebum production, which can clog the follicles. This disrupts the natural hair growth cycle and may cause the hair strands to fall off. Excess sebum also favours Malassezia overgrowth, which, in turn, weakens the hair roots.

The immune system readily reacts to infection and inflammation and deploys immune cells to address the issue. This attack may affect the hair follicles and is known to cause changes in the scalp's skin.

Therefore, while it is untrue that dandruff causes hair fall, the itchiness caused by the condition may trigger it.

Effective Dandruff Treatments for Healthy Hair

Several medical and natural ingredients aid in hair dandruff treatment. Depending on the nature and severity of the dandruff, you can opt for either treatment. However, a dermatologist consultation is recommended to ensure you do not irritate your scalp further.

Medicated Shampoos and Treatments

Several over-the-counter and prescription shampoos are available for dandruff treatment. In mild cases of dandruff, medicated shampoos for a few weeks can effectively remedy the condition. Some common ingredients in these shampoos include:

• Salicylic acid
• Selenium sulphide
• Ketoconazole
• Pyrinthione zinc

Selenium sulphide is not recommended for people with light-coloured hair as it can cause discolouration. Also, it is crucial to condition your hair after shampooing to prevent a dry scalp.

Natural Remedies for Dandruff

Some natural ingredients often found at home serve as the best dandruff treatments. The following sections discuss some of the most effective remedies for this condition and the related symptoms.

1. Apple Cider Vinegar

   Apple cider vinegar is an effective antibacterial, antifungal, and antioxidant agent. It promotes scalp and follicles health and offers several benefits.

   Mix apple cider vinegar with equal amounts of water as a hair dandruff solution. Massage the mix onto a clean scalp for 5 minutes, then rinse with water after about 20 minutes. Do not use concentrated apple cider vinegar.

2. Lemon Juice and Coconut Oil

   Coconut oil soothes and moisturises the scalp, while lemon juice has antioxidant properties. Mixing equal parts coconut oil and lemon juice acts as an effective natural remedy for dandruff and prevents hair loss due to dandruff. Apply this mixture to the scalp and massage for up to 10 minutes. Wait for about an hour before shampooing your hair.

3. Fenugreek Seeds

   Fenugreek seeds are among the best natural treatments for dandruff. To use it, soak some seeds in water overnight and make their paste in the morning. Add lemon juice to the paste, then apply it to a clean scalp. Leave it for up to 30 minutes, and then shampoo your hair.

4. Mehndi or Henna

   Henna or mehndi is among the best natural remedies for dandruff. Mix mehndi with curd, lemon juice, and water and leave it overnight. In the morning, apply it to a clean scalp and strands. This removes the dandruff, softens your hair, and adds shine.

Combating Hair Loss Caused by Dandruff

Dandruff causes hair loss, which can be prevented by addressing the condition and taking appropriate preventive measures. The following sections discuss how dandruff can cause hair loss.

Understanding Hair Loss Mechanisms

The following factors can trigger hair loss:

• Clogged hair follicles
• Weak hair follicles
• Shrunk hair follicles
• Dry skin
• Inadequate blood supply to the scalp
• Lack of proper nutrition to the follicles
• Underlying condition
• Certain medications and treatments

Impact of Dandruff on Hair Follicles

Dandruff causes itchiness, inflammation, and irritation, which damages the hair follicles and makes the scalp more prone to infections. This disrupts the proper growth of hair and triggers hair fall. Dandruff has also been found to trigger hair loss among individuals suffering from androgenic alopecia, a condition that leads to male and female pattern baldness.

Lifestyle Changes for Dandruff Prevention and Hair Health

Like several other aspects of your life, your daily habits and lifestyle also affect your hair and scalp health. By making a few adjustments to your lifestyle, you can prevent dandruff in the future and attain good hair and scalp health.

Stress Management Strategies

Stress is not known to cause dandruff directly. However, it gradually weakens the immune system, making a person more prone to infections caused by bacteria and fungi naturally residing on the scalp.

Therefore, engaging in stress management practices is crucial for hair health. Adopt a relaxing habit to engage in daily. This could be a sport, journaling, reading a book, taking a walk, working out, or any other activity that helps you release the stresses of everyday life. Regular meditation and yoga are also effective stress management strategies. A brief but direct exposure to the sun is also known to prevent dandruff.

Dietary Recommendations

A diet with low sugar content and ample amounts of zinc, healthy fats, and vitamin B-complex helps address and prevent dandruff. Allicin is also an essential part of the anti-dandruff diet. It is a phytochemical in Allium plants like onions and garlic and has remarkable antifungal properties.

Scalp Hygiene Practices

Maintaining scalp hygiene is crucial to eliminating and preventing dandruff and all related hair issues. Follow these tips to ensure a dandruff-free scalp:

• Avoid hair care products with natural or artificial fragrances
• Use non-comedogenic hair care products
• Avoid hair products containing bleach, detergents, or formaldehyde
• Oil your scalp regularly
• Wash your hair at least once or twice in a week
• Avoid overwashing your hair and scalp
• Wear a hat or a scarf when going out in the dust and to prevent prolonged sun exposure
