How Pollution Impacts Hair Color And Texture

It is well-known that air pollution can be harmful to health, but can it also affect hair colour? Research suggests that it can.

Hair is composed of heavily melanized keratin fibres, which are classified as hard keratins, consisting of 65-96% proteins, 1-9% lipids, 3% melanin, and other minor compounds. The hair structure is gradually damaged by day-to-day insults such as washing, brushing, and the use of thermal tools, as well as exposure to UV radiation and pollution.

Air pollutants consist of complex and varying mixtures of different-sized particles suspended in the air, including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), nitrogen oxides (NOx), particulate matter (PM), ozone, and cigarette smoke. These pollutants can bind to the hair's surface, infiltrating the follicle and settling on the scalp.

Particulate matter, or particle pollution, is a term that describes a mix of solid particles and small liquid droplets, made of various chemicals, that people can inhale. Some of these particles pose serious health risks and have been linked to an increased risk of diverse diseases, including cancer, pulmonary, respiratory, and cardiovascular diseases, as well as skin diseases.

Recent research has provided strong evidence for a link between exposure to pollution and hair loss. Studies have shown that pollution can alter the condition of the hair cuticle, giving hair a rough, brittle, and dull appearance. It can also contribute to scalp itching, irritation, excess sebum production, and dandruff, all of which can clog follicles, weaken the hair at the root, and make it more susceptible to breakage and fallout.

While the impact of pollution on hair health and hair loss is a growing area of research, the specific effects of pollution on hair colour have not been widely studied and remain unclear. However, it is known that UV radiation from sunlight can cause chemical changes in hair, and that PAHs can cause oxidative stress to hair when exposed to UV radiation, leading to increased damage to the hair cuticle and cortex.

Therefore, while the direct impact of pollution on hair colour may not be fully understood, it is clear that pollution can have significant detrimental effects on overall hair health, including potential changes to hair appearance and texture.

Particulate matter binds to the hair and scalp, causing damage

Particulate matter, or particle pollution, is a term that describes a mix of solid particles and small liquid droplets, composed of various chemicals, that can be inhaled. These particles can bind to the hair and scalp, causing damage. The particles infiltrate the hair follicle and settle on the scalp, altering the condition of the cuticle and giving hair a rough, brittle, and dull appearance. This damage can result in breakage, weakened hair strands, and overall dryness.

How Particulate Matter Damages the Hair and Scalp

When particulate matter binds to the hair and scalp, it can cause a range of issues, including:

• Scalp itching, irritation, and inflammation
• Increased sebum production and dandruff, which can clog follicles and weaken the hair at the root
• Hair loss and impaired hair growth
• Altered hair surface properties and hair quality
• Oxidative stress and inflammation, which can impair hair growth
• Damage to the hair cuticle, cortex, and keratin proteins

Sources of Particulate Matter

Particulate matter can come from a variety of sources, including:

• Dust and diesel
• Smoke from car exhaust, asphalt, and industrial smoke
• Power plants, industries, and automobiles

Protecting the Hair and Scalp from Particulate Matter

To protect the hair and scalp from the damaging effects of particulate matter, it is important to use products that create a protective barrier against pollution. Ingredients such as vegan silk peptides, antioxidants, and hyaluronic acid can help defend the hair and scalp against the negative effects of pollution. Regular use of products containing these ingredients can provide physical protection, rebuild damage, and improve hair smoothness and shine.

Air pollution can cause hair loss

Air pollution is a serious issue that not only affects our respiratory health but also our hair and scalp health. The direct exposure of our hair and skin to pollutants in cities can have detrimental effects. Large suspended particles, small airborne particles, smoke, and gaseous pollution can all reach the scalp and hair, causing irritation and damage. Here are some ways in which air pollution can contribute to hair loss:

Impact on Hair Follicles and Keratinocytes

Particulate matter, or particle pollution, refers to a mixture of solid particles and small liquid droplets made up of various chemicals that can be inhaled. These particles can infiltrate the hair follicle and settle on the scalp. Research has shown that exposure to particulate matter can lead to a decrease in key growth proteins such as beta-catenin, cyclin D1, cyclin E, and CDK2, which are essential for new hair formation. This reduction in growth proteins can result in hair loss. Additionally, increased exposure to pollution can lead to oxidative stress and inflammation, further impairing hair growth.

Scalp Health and Sensitivity

Pollution deposits on the scalp can contribute to several issues, including itching, irritation, excessive sebum production, and dandruff. These symptoms can clog follicles, weakening the hair at the root and making it more prone to breakage and fallout. The combination of these symptoms is known as sensitive scalp syndrome. Excessive sebum production can lead to oily roots, clogged pores, and blocked hair follicles, further contributing to hair loss.

Oxidative Stress and Inflammation

Air pollution, particularly particulate matter, can induce oxidative stress and increase the production of reactive oxygen species (ROS) and inflammatory cytokines. This, in turn, can impair hair growth and lead to apoptotic cell death, especially in follicular keratinocytes. Inflammatory cytokine expression was found to be increased after exposure to particulate matter, and high doses of these cytokines have been linked to apoptosis of hair bulb keratinocytes.

Hair Quality and Texture

Severe air pollution can alter the condition of the hair cuticle, giving it a rough, brittle, and dull appearance. Hair fibres exposed to higher levels of pollutants experience increased damage to the hair cuticle, cortex, and keratin proteins, resulting in breakage, weakened strands, and overall dryness. This damage can further contribute to hair loss.

In summary, air pollution can have significant negative effects on both the hair and the scalp, ultimately contributing to hair loss. It is important to take steps to protect hair and scalp health, such as using protective hair care products and treatments that create an eco-barrier against pollutants. Additionally, treating hair and scalp issues early on is crucial to preventing further damage and hair loss.

Hair loss due to pollution can mimic androgenetic alopecia

Hair loss due to pollution can take on an irregular, amorphous pattern and coexist with or even mimic androgenetic alopecia.

The Impact of Pollution on Hair

Pollution is composed of particulate matter (fragments of dust, soot, and grime) and gaseous pollutants. These particles can bind to the hair's surface, infiltrating the follicle and settling on the scalp. Severe air pollution can alter the condition of the cuticle, giving hair a rough, brittle, and dull appearance.

Recent research has provided strong evidence for the link between exposure to pollution and hair loss. Researchers exposed dermal papilla cells—the cells located at the bottom of the hair follicle and responsible for hair formation and growth—to various levels of polluted air composed of diesel and dust for 24 hours. The results revealed a significant decrease in key growth proteins, including beta-catenin, cyclin D1, cyclin E, and CDK2. Beta-catenin is crucial for the formation of new hairs. Increased exposure to pollution resulted in a greater reduction of essential hair growth proteins and mechanisms, indicating that air pollution may cause cell death to follicular keratinocytes.

The Impact of Pollution on the Scalp
