What is the effect of smoking on hair loss? Is E-Cigarette also harmful for hair? Which brings us to another question: Is hair loss reversible?

A] What is the effect of smoking on hair loss?

The ill effects of smoking go beyond our lungs and even affect our hair. There are thousands of chemicals in tobacco smoke and when you breathe in these chemicals, they can travel from your lungs to your bloodstream. These can then spread from your blood to other parts of your body and cause harm to your health such as increasing the chances of hair loss.

1. Dead Hair Follicles

The main cause of hair thinning lies in dormant or dead hair follicles. Your hair follicles need nutrients and oxygen to remain healthy and when they do not receive the necessary nutrients as a result of smoking, they die over time, resulting in hair thinning. And when the hair follicles are injured, it becomes difficult to regrow new hair or even keep current hair growing healthily. Excessive smoking, with its harmful elements, might entirely disrupt your hair development cycle. Smoking can cause many problems for your hair because it has a deeper influence in the scalp since it shrinks the blood vessels that deliver the vital nutrients such as vitamins and minerals as well as oxygen to the hair follicles.

According to a 2018 study, tobacco smoke contains over 7,000 harmful compounds that can travel from your lungs to your bloodstream. They can travel to other parts of your body through your blood and can have a harmful impact on many aspects of your health along with your hair.

2. Weakened Immune System

Other than this, a Weakened Immune System also reflects on the health of your hair. And smoking cigarettes weakens the immune system, resulting in infections or disorders that causes hair loss. A bacterial or fungal infection on the scalp, which can hinder your follicles from creating healthy hair, is also more likely if you have a weak immune system.

3. Blood flow to hair follicles is decreased

The various chemicals in tobacco can have harmful effects on the circulation of blood in your body. Your hair follicles receive nourishment through blood vessels which deliver nutrients and help get rid of waste. Reduced or hampered blood flow to your scalp could lead to hair loss or hair damage.

4. Polluted Air

And inhaling cigarette smoke isn't the only thing that might destroy your hair follicles. If you have a habit of smoking at home or in a car with the windows rolled down, you are also polluting the environment. While the majority of hair loss is due to genetics, lifestyle, smoking, etc. Research has linked hair thinning to environmental causes as well. Polluted air can aggravate genetic hair loss, and carcinogens in smoky air can hinder the systems that make the protein that makes hair.

5. Other factors

There are certain other changes that smoking causes in your body that could result in hair loss. Some of them are:

- Smoking releases cytokines, which signals proteins that promote inflammation. Increased levels of cytokines lead to scarring of your hair follicles, which increase the risk of hair fall.

- Fluctuating enzyme levels that control your hair growth cycle. Any hindrance to the hair growth cycle affects the growth of your hair.

B] Is E-Cigarette also harmful for hair?

Many people have shifted to E-cigarette, Vape, and Juuls to start their journey of quitting Cigarettes but another question arises from this. Does smoking an e-cigarette or vaping cause hair fall as well? Here’s what we know: Juuling, Vaping and smoking E-cigarettes have an adverse effect on hair, resulting in hair loss. Vaping can inflict harm that is as adverse as smoking normal cigarettes as the smoke from vaping can damage your hair follicles, which might result in hair loss. According to research, this type of hair loss is also extremely difficult to treat, and in some cases, the hair loss may be irreversible.

C] Which brings us to another question: Is hair loss reversible?

Quitting smoking is the most effective strategy to reverse hair loss caused by smoking. Your hair should start growing again once you stop exposing your hair and skin to the poisons in cigarettes. By restricting normal blood and nutrient flow to the hair follicles, smoking is a major contributor to hair loss. When you stop smoking, your blood vessels will shrink less, and your hair follicles will become active and healthy again. Furthermore, because a hair follicle grows out of a hair follicle, your hair will regrow healthy.

As a result, if you stop smoking, you could help your hair regenerate. If you keep your scalp tissues free from the toxic poisons of cigarettes, your body has a natural way of regenerating the loss. Quitting smoking is the most effective strategy to repair the damage done to your hair and try to regrow healthy hair.

Along with quitting smoking, you will need a haircare routine to regenerate the good quality of your hair which has been degraded and for that you will need hair products which will nourish your hair and make them stronger and healthier.
