Smoking Can Cause Hair Loss: Here’s The Truth!

Negative Impact Of Smoking

Its well known fact that smoking tobacco takes a serious toll on overall health. The US FDA states that none of the tobacco products are safe.^[1] While tobacco-related deaths mostly happen due to respiratory issues and lung cancers, smoking exposes you to over 7,000 toxic chemicals. Among them, 70 are carcinogens, which, when inhaled and overexposed, cause cancers. Toxins such as arsenic, benzaldehyde, benzene, and formaldehyde damage the internal organ systems. In simple terms, the chemicals released from the mix of tobacco, chemical additives, the filter, and paper negatively impact almost all cells of the body. Hair follicles are not an expectation here! 

Busting The Smoking Hair Loss Myth

While there is a strong misconception that smoking is related to hair loss, studies reveal something else. The harmful toxins and combustion products of smoking harm the hair follicles and disturb scalp health. We addressed this in the upcoming section by detailing the most commonly asked questions. 

Will Smoking Cause Hair Loss?

Studies suggest that smoking has a negative impact on hair health. Smokers experience pronounced hair fall compared to non-smokers.^[2] This is particularly true for candidates at risk of developing androgenic alopecia. Candidates with a risk of androgenetic alopecia experience hair follicle miniaturization because of increased sensitivity to androgen dihydrotestosterone (DHT). For them, smoking speeds up hair thinning by disrupting the hormonal cycles. Not just that, the tobacco products increase the risk of premature hair greying. 

Hair Loss Due To Smoking: Is It Gender Biased?

Hair loss due to smoking is not gender biased. The harmful effects of smoking remain more or less the same in men and women. However, the appearance and intensity of hair loss depend on underlying hormonal and genetic factors. We answer a few questions that most patients ask us.   

Does Smoking Cause Hair Loss In Females?

Yes, smoking causes hair loss and thinning in women. Nicotine and other harmful chemicals damage the follicles by limiting the scalp's nutrient and oxygen supply. Hair loss in women generally appears as thinned hair with a widened part. Brittle hair and a dry scalp reduce hair quality over time.    

Can Smoking Cause Hair Loss In Males?

Hair loss due to smoking in men appears more pronounced on the vertex with a slight patch on the back of the head. Smoking actually accelerates the pattern baldness in men by increasing follicular sensitivity to DHT. So the outcomes are similar to bald crown, with M-shaped patch or receding temples, deepening inward, and a healthy hair patch at the back of the head.   

How Can Smoking Cause Hair Loss?

Smoking tobacco releases a primary compound, nicotine, into the bloodstream, which is carried immediately to the lungs and brain.^[3] Nicotine and other chemicals released as products of smoking limits blood and oxygen supply to the scalp. It's because nicotine is a vasoconstrictor and slows down the peripheral blood supply.^[4] Limiting the blood supply cuts down oxygen and nutrient supply to the hair follicles. This leads to weaker and thinner hair strands that are brittle and easy to break. In addition, the other chemicals in the smoke produce oxygen-free radicals that attack and damage the DNA of hair follicles. This damage takes a step forward, hurting the follicle's ability to regenerate. Besides, the negative effects are diverse, shortening the growth phase of hair follicles. So the hair follicles enter a resting phase too soon, leading to hair thinning and increased hair fall. With ongoing hair fall and reduced regrowth, this imbalance gradually leads to visible thinning and, in some cases, noticeable hair loss. So, when someone asks, “Can smoking cause hair thinning?” the answer is a definite yes.

Does Vaping Cause Hair Loss?

Vaping, in the form of e-cigarettes or vape pens, leads to hair thinning and decreased growth, which is noticeable in a few months. While vaping is generally called out to be less harmful than smoking, the hard reality is different. The adverse effects are similar to how cigarette can cause hair loss. 

Although vaping avoids the release of combustible toxins, the negative effects of nicotine remain more or less the same. The liquids used in vaping contain nicotine and flavoring agents. The aerosol inhaled through e-cigarettes contains nicotine, whose adverse effects on hair remain more or less the same. The reduced blood flow to the scalp deprives nutrient and oxygen supply. In addition, the oxidative stress disturbs the hair follicles' ability to regrow. So while vaping avoids smoke, the harmful effects are more or less the same.       

Does Chewing Tobacco Cause Hair Loss?

Yes, chewing tobacco negatively impacts hair growth by making it brittle and weak, and leading to premature greying. It also damages hair follicles through direct absorption of nicotine and other harmful chemicals. Nicotine triggers the production of oxygen-free radicals, causing oxidative stress. Oxygen-free radicals are highly unstable and damage hair follicle DNA, disrupting their natural growth cycle. In addition, the chemicals in smokeless tobacco cause premature hair greying. Besides, chewing tobacco releases harmful carcinogenic arsenic. Arsenic has a higher affinity for keratin, the main protein in hair.^[6] It accumulates at higher concentrations in people who consume tobacco.  

Does Smoking Weed Cause Hair Loss?

Yes, smoking weed can cause hair loss, but this is generally less talked about compared to the other health issues it can cause. It is, in fact, dangerous with long-term health risks, such as lung irritation, coughing, and memory and focus issues. It increases phlegm production, leading to a chronic cough and conditions such as bronchitis. But the effects on the brain are serious to consider. It causes dizziness and prolongs judgment and response time. Long-term usage increases the risk of heart attacks by persistently increasing blood pressure.    

Can Hair Loss From Smoking Be Reversed?

Hair loss from smoking can be reversed, and regrowth is possible by quitting smoking. However, the extent of recovery may vary, especially in long-term smokers or those with pattern baldness. Smoking-induced hair fall is mainly caused by restricted nutrient and oxygen flow to the hair follicles. Quitting smoking reduces exposure to toxins in the body and on the scalp. Stopping tobacco consumption allows oxygen and nutrient flow, aiding in follicle rejuvenation. In addition, a few lifestyle changes, such as scalp massages, relaxation activities to reduce stress, and a nutrient-rich diet, boost results. While hair regrowth is possible, the extent of recovery depends on how heavily and how long you have smoked. If hair loss is severe, it's better to seek supportive hair loss treatments such as PRP or exosome therapies. These enhance scalp blood circulation and supply the damaged follicles with the required growth factors and proteins. 

When Will Hair Loss From Smoking Grow Back?

While growth is possible, expecting instant results is not advised. You should wait 3-6 months for noticeable hair regrowth. Quitting smoking regains healthy blood circulation to the scalp within 2-4 weeks. However, the hair follicles that entered a temporary resting phase should re-enter the growth phase. This will take a few weeks, so you will notice visible hair regrowth results within 3-6 months. 

How Is Smokers Hair Before And After Quitting? 

A smoker's hair before quitting is generally brittle, weak, and sparse with less density. Smoking limits blood flow to the scalp, and poor circulation leads to dull, dry, and easily breakable hair. Upon quitting smoking, hair regrowth happens within 3-6 months. You will experience improved scalp circulation with better texture. The hair follicles re-enter the growth phase, and you will notice visible results.     

Quitting Smoking

Your health doctor may help you find the right approach to quit smoking. Here we detail a few ways that may be helpful.

• Professional help: Some professionals prescribe nicotine replacement options such as patches, gums, and inhalers. These help you slowly wean down the nicotine consumption. Certain prescription drugs cut down cravings and ease your withdrawal symptoms. These also work as a combined approach, helping smooth your quitting journey.
• Supportive therapies: You may join support groups or seek professional help, such as counseling. Frequently getting in touch with people who quit smoking and are enjoying a better lifestyle acts as a positive boost.  
• Avoiding smoking environments: Staying away from areas where people smoke cuts down temptations and helps you stick to a quitting mindset without deviation. 
• Technological support: There are many apps available that help you quit smoking in an easy, supportive way. They send reminders and motivational messages, and split your quitting journey into simple, manageable steps.

What Can Help With Hair Loss?

While quitting smoking can reverse hair loss, adding a few supportive measures can also help boost the quality of results.

• Adding a healthy diet and exercise routine will ensure your body is properly nourished and is receiving adequate blood circulation. 
• A stress-free lifestyle supports healthy hair growth cycles and helps prevent premature greying. Relying on meditation, limiting caffeine, setting boundaries, and focusing on nurturing connections will help you lead a stress-free, happy life.
• Supportive therapies such as PRP, low-level lasers, and exosome therapy support hair regrowth by supplying follicles with growth factors and essential nutrients.
