Similarly, if you have been experiencing hair loss, then smoking certainly is the cause of it. Want to know how and why does smoking causes hair loss? We have every answer to all the questions popping in your mind.
Does Smoking Really Cause Hair Loss?
While there are various factors from heredity to lack of nourishment that contribute to hair loss, smoking is also one of them. Smoking cigarettes have an adverse effect even on your hair just as it has on your skin. The chemicals in the cigarettes can affect your hair follicles and tend to damage them. These thus lead to hair thinning and extensive hair loss. Smoking can also make your hair brittle and prone to easy breakage.
Major Effects of Smoking on Your Hair
- Smoking tends to cause premature graying of your hair.
- It depletes the collagens and moisture from your hair which leads to reducing naturally inducing hair oils. It leaves your hair dehydrated and dry.
- It boosts excess sebum secretion and makes your scalp oily and greasy, thus clogging hair shafts.
- It hampers the endocrine system which leads to disruption of healthy hormone production. This leads to a lesser supply of nourishing nutrients to your hair follicles.
- The hair strands from your hair follicles will appear thinner.
- It may cause inflammation of the scalp and can even lead to bald patches.
Additional Factors to Smoking that Lead to Hair Loss
While smoking leads to hair thinning and hair loss, there are other additional factors that can aggravate it further. Below are some reasons that work as an add-on to smoking that leads to hair loss –
Disrupted Blood Circulation
Your hair sees changing phases in the growth cycle – the growing phase, the transitional phase, the resting phase, and the usual shedding phase. However, when the right amount of nutrition isn’t produced or supplied to the blood vessels and hair shafts then your hair’s growing cycle goes under stress.
When these minerals, nutrients and oxygen are not supplied properly to your follicles, they enter a permanent or prolonged resting phase and fail to produce healthy hair. As a result, the hair strands continue to shed at a similar rate, however, the follicles cannot replace them due to lack of nourishment. In fact, the toxins present in a cigarette can, not only affect the blood circulation, but also shrink blood vessels, and impede blood flow thus preventing proper functioning.
Pollution and Other Environmental Factors
While most of the time hair loss is genetic, various researches have linked thinning hair to environmental factors. Every time you smoke, the fumes of smoke released in the air can easily be soaked up by your hair. This causes damage to your hair and can lead to hair loss. The harmful pollutants like cotinine and nicotine released from cigarettes can lead to permanent damage to your hair structure.
These toxins get accumulated in your hair follicle and hair shaft and can make your hair fall out. And if the toxins have alkaline elements, they can also disturb the pH level of your scalp which can affect your hair growth. While nicotine can reduce blood pressure across your scalp and damage blood vessels causing your hair to clot more often and causing breakage.
Weak Immune System
Your immune system is most certainly hampered due to extensive smoking. It goes without saying that smoking makes your body more prone and vulnerable to infections and illness. Be it the slightest cold or any other disease, a weakened immune system ensures that even the slightest of flu lingers on longer than usual. In fact, a poor immune system may also increase your chances of fungal or bacterial infection on the scalp. These infections could restrict the follicles from producing healthy hair and lead to hair loss.
Increases The DHT Production
DHT, that is dihydrotestosterone is a type of hormone that is usually affected due to smoking. The DHT usually determines the hormone levels in males and helps in enhancing their masculine traits amongst other effects. In fact, it is also highly believed that DHT plays a key role in affecting the hair growth cycle in both male hair loss and female hair thinning.
When it comes to smoking, it can take a huge toll on the body’s endocrine system which thus leads to high DHT levels. This hormonal change or increase in DHT leads to made pattern baldness. 
In fact, the increase in DHT products due to smoking can also lead to hair follicle shrinkage thus stopping new hair growth. The growing phase of the hair shortens with passing time, the follicles then stop growing the hair through the skin. As a result of this, the hair thinning aggravates with each hair growth cycle making them brittle, weak and more prone to breakage and falling.
One of the major factors that most people claim why they smoke is stress. Often people smoke when under a lot of stress and anxiety. Stress itself is known to cause hair loss and when the factor of smoking is added to it, it only aggravates further. It causes a rise in blood pressure levels, increases heart rate, and even tenses up your muscles. Thus when these two factors – smoking and stressing come together, it usually disrupts your hair cycle and causes hair loss.
