Did you know that researchers have found that heavy smokers had a threefold increased risk of moderate/severe alopecia (male patterned baldness) compared to non-smokers? This shows how much smoking significantly affects our hair health. It gets especially worrisome to many if smoking does in fact cause hair loss and rightfully so.
So, does smoking cause hair loss? The answer is yes. Smoking impacts hair health negatively by restricting blood flow to hair follicles, introducing harmful toxins, and accelerating aging processes that affect the scalp and hair.
In this article, we will explore how smoking can be related to hair damage, the science behind this connection, and practical steps you can take to protect your hair from the harmful effects of tobacco.
Smoking and Hair Loss
Smoking is known to have severe impacts on health. It can cause lung cancer, heart disease, and respiratory problems. The harmful chemicals in cigarettes damage almost every organ in the body. They weaken the immune system and slow down the body’s healing process. While these health issues are well-known, smoking also affects hair health.
But can smoking cause hair loss? Well, Smoking can lead to hair loss in several ways. First, smoking reduces blood flow to hair follicles. Less blood flow means hair follicles get less oxygen and nutrients essential for hair growth. Second, the toxins in cigarette smoke can damage the DNA in hair follicles. This damage weakens hair structure and growth. Third, smoking speeds up the aging process, causing premature graying and thinning of hair.
Additionally, smoking triggers inflammation and oxidative stress in the body. These conditions create an unhealthy environment for hair growth. Oxidative stress damages hair follicles, and inflammation can disrupt the normal hair growth cycle. Together, these effects make it clear that smoking not only harms your internal health but also contributes to hair loss.
Understanding the impact of smoking on hair health is crucial. By quitting smoking, you can:
- Improve overall health.
- Prevent further hair loss.
- Give your hair a better chance to grow and thrive.
How Does Smoking Cause Hair Loss?
smoking causes hair fall due to various mechanisms;
1. Reduces Blood Flow
Smoking narrows blood vessels, also known as vasoconstrictor action, which cuts down the amount of blood that reaches hair follicles. Hair follicles need a steady supply of blood to get oxygen and nutrients. With less blood flow, hair follicles can’t grow hair as effectively, leading to thinner and weaker hair. A study from 2016 found that smokers had significantly reduced scalp blood flow compared to non-smokers, contributing to hair follicle miniaturization and hair loss.
2. May Damage DNA in Hair Follicles
The chemicals in cigarette smoke can damage the DNA in hair follicles. This damage disrupts the normal hair growth cycle, making it harder for hair follicles to produce healthy hair and causing more hair to fall out. Research conducted in 2018 demonstrated that the genotoxic substances in cigarette smoke could induce mutations in hair follicle cells, leading to impaired hair growth and increased shedding.
3. Oxidative Stress
Smoking creates free radicals, which are harmful molecules that cause oxidative stress. This stress damages the cells in hair follicles, interfering with their ability to grow hair and leading to increased hair loss.
What is Oxidative Stress?
Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. Free radicals are unstable molecules that can damage cells, while antioxidants neutralize these harmful molecules. When free radicals overwhelm the body's antioxidant defenses, oxidative stress results, leading to cell damage and inflammation.
4. Chronic Inflammation
Smoking causes long-term inflammation around hair follicles. This inflammation can create scar-like tissue around the follicles, making it harder for them to function properly and leading to hair loss.
5. Accelerates Aging
Nicotine in cigarettes speeds up the aging of cells, including those in hair follicles. This causes hair follicles to age faster than normal, leading to premature thinning and loss of hair. A 2019 study reported that smokers showed signs of accelerated cellular aging in their hair follicles, with markers of senescence appearing earlier compared to non-smokers.
6. Hormonal Changes
Smoking can affect hormone levels in the body. It may increase the levels of certain hormones that contribute to hair thinning, especially in people who are already at risk for hair loss due to genetics. In 2020, researchers found that smoking was associated with elevated levels of dihydrotestosterone (DHT), a hormone known to contribute to androgenetic alopecia.
7. Decreases Hair Follicle Size
Smoking can cause hair follicles to shrink, which results in smaller hair strands and reduced hair density. Smaller hair follicles produce weaker hair, leading to increased shedding and thinner hair. A study conducted in Japan in 2014 found that smokers had significantly smaller hair follicle diameters compared to non-smokers, contributing to overall hair thinning.
8. Nutrient Deficiency
Smoking can reduce the absorption of essential nutrients, such as vitamins and minerals, that are important for hair health. Lack of these nutrients can weaken hair follicles and lead to increased hair loss. It was also found that smokers had lower serum levels of vitamins C and E, which are crucial for maintaining healthy hair growth, leading to higher incidences of hair loss among smokers.
Other Ways Smoking May Contribute to Hair Loss
In addition to the mechanisms mentioned, smoking can cause hair loss in several other ways:
Telogen EffluviumTelogen effluvium is a condition where a lot of hair suddenly enters the resting phase of the hair growth cycle. This causes increased hair shedding. Smoking can increase both physical and mental stress, which can trigger this condition. More stress from smoking can lead to more hair falling out.
Compromises Immune SystemSmoking weakens your immune system. A weak immune system makes you more likely to get infections and diseases, including those that affect your scalp and hair follicles. This can lead to conditions where the body's immune system attacks hair follicles, causing hair to fall out.
Synergistic Effects with Other Hair Loss FactorsSmoking can also work together with other factors that cause hair loss, like genetics and stress. If you have a family history of hair loss, smoking can make it happen sooner and make it worse. Smoking can add to the stress you already feel, leading to even more hair loss. This combination of factors can have a stronger effect on your hair than any single factor alone.
Harms Hair TextureSmoking can make hair dry and brittle. The chemicals in cigarette smoke strip hair of its natural oils, which keep hair soft and smooth. Without these oils, hair becomes rough and breaks more easily. This can make hair look frizzy and unhealthy.
Weakens Hair StrengthThe toxins in cigarette smoke weaken hair strands. Smoking reduces the nutrients that reach hair follicles. Without enough nutrients, hair becomes weak and breaks more easily. This results in thin, fragile hair.
Overall Hair HealthSmoking affects overall hair health in many ways:
- Increases Hair Loss: Smoking speeds up hair loss due to reduced blood flow, oxidative stress, and harmful chemicals.
- Slower Hair Growth: A lack of nutrients and oxygen slows down hair growth. Hair may grow back more slowly after shedding, leading to thinner hair.
- Damage to Hair Follicles: Toxins from smoking damage hair follicles, making them less effective at producing healthy hair. This can lead to permanent hair loss if the follicles are damaged beyond repair.
Smoking hair loss myth
The idea that smoking directly causes hair loss is often debated, but there's evidence suggesting a connection. Smoking can lead to hair loss by affecting blood flow, increasing oxidative stress, and causing inflammation, all of which can harm hair follicles. While smoking alone might not be the sole cause of hair loss, it can contribute to it, especially when combined with other factors like genetics or poor diet.

Does Vaping Cause Hair Loss?
Vaping, like smoking, can have negative effects on hair health. Though vaping is often marketed as a safer alternative to smoking, it shares many harmful components with traditional cigarettes.
Here is a table for a better understanding between the two:
Smoking |
Vaping |
Contains nicotine, a known vasoconstrictor |
Usually contains nicotine, also a vasoconstrictor |
Contains tar, carbon monoxide, and other harmful chemicals |
Contains fewer toxins, but still harmful chemicals like formaldehyde and acrolein |
Generates high levels of free radicals |
Also generates free radicals, though potentially at lower levels |
Numerous additives and flavorings |
Variety of flavorings, some of which may be harmful |
Involves combustion, creating toxic byproducts |
No combustion, but still produces aerosol that may carry toxins |
Reduces blood flow to hair follicles |
Can reduce blood flow due to nicotine |
Causes inflammation in the body |
Can cause inflammation, though its effects are still being studied |
Nicotine Effects
Both vaping and smoking deliver nicotine, which can cause vasoconstriction, or the narrowing of blood vessels. This reduces blood flow to hair follicles, depriving them of essential nutrients and oxygen. Reduced blood flow can weaken hair follicles and lead to hair loss.
Toxins and Chemicals
While vaping typically contains fewer toxins than traditional cigarettes, it is not free from harmful chemicals. Vaping liquids often contain substances like formaldehyde and acrolein, which are known to cause cellular damage. These chemicals can contribute to oxidative stress, damaging hair follicles and potentially leading to hair loss.
Oxidative Stress
Both smoking and vaping generate free radicals, which cause oxidative stress. Oxidative stress damages cells, including those in hair follicles. While vaping might produce lower levels of free radicals compared to smoking, it still poses a risk to hair health by contributing to cellular damage and inflammation.
Inflammation
Vaping can also cause inflammation in the body, though the extent and mechanisms are still under study. Inflammation around hair follicles can lead to conditions like perifollicular fibrosis, where scar tissue forms around the hair follicle, impeding hair growth and contributing to hair loss.
In summary, while vaping might be less harmful than smoking, it still carries risks for hair health. The nicotine, toxins, and potential for oxidative stress and inflammation from vaping can contribute to hair loss. Reducing or eliminating vaping, like smoking, can help improve overall hair health.
