Does smoking affect hair loss?

The health damage caused by smoking is more than known: respiratory diseases, heart disease, cancer, periodontal diseases, premature aging, among others. However, many smokers are unaware that tobacco use can also affect the appearance and health of their hair.

Quitting tobacco is one of the best decisions you can make, and today on the Hairfix blog we will tell you how smoking affects hair health and its relationship with alopecia. Stay and read!

Does smoking damage hair?

Is there really a risk of hair loss from smoking? The harmful potential of smoking has implications in the following areas:

Blood circulation

Smoking is the main cause of cardiovascular disease (CVD), as well as one in four associated deaths. This is because it causes the blood to thicken, thrombi or clots to form, and block blood flow to the heart and brain. In addition, blood vessels are affected by the accumulation of fat, cholesterol and toxic substances from cigarettes that harden and widen them.

The inadequate supply of oxygen through blood circulation damages the blood vessels of the hair bulb, that is, the base of the pillar follicles that receive the nutrients and hormones that modify the growth and structure of the hair.

Without these nutrients, the hair growth cycle is affected, so it can appear dry, brittle and prone to loss.

Furthermore, this situation not only affects active smokers, but also passive smokers who receive cigarette smoke can have the same consequences on their hair health.

Androgenic alopecia and smoking

In previous posts we have told you about androgenic alopecia, which is a genetic predisposition to male pattern hair loss. While this is a “natural” condition, smoking can exacerbate or accelerate the process.

A recent study published January 4, 2024 in the Journal of Cosmetic Dermatology led by Dr. Aditya K. Gupta, of Mediprobe Research Inc. (London, Ontario, Canada) and the University of Toronto Faculty of Medicine ( Toronto, Ontario, Canada), revealed that male smokers are more likely to develop androgenic alopecia and experience accelerated progression of male pattern hair loss.

In a meta-analysis with 4,462 men from eight observational studies in Europe, Asia and Oceania, the probability of presenting male pattern hair loss was compared among smokers who consumed at least 10 cigarettes per day, finding a 96% greater probability of presenting androgenic alopecia. than others who smoked less.

Increased DHT production

Smoking can cause an increase in the production of DHT, dihydrotestosterone: a derivative of testosterone and is responsible for men developing masculine traits, including sexual organs and hair growth on different parts of the body, such as arms and legs. However, this same role plays against hair loss since DHT affects the hair growth cycle.

DHT can inhibit and shrink hair follicles, reduce the duration of the hair growth phase (anagen) and increase the duration of the hair loss phase (telogen). The result is thinning hair with each hair cycle.

Can smoking affect the results of hair transplants?

If you are considering a hair transplant and you are a smoker, you should know that, as we already mentioned, smoking causes vasoconstriction of the capillary vessels in the scalp, preventing the arrival of nutrients to the transplanted follicular units.

On the other hand, nicotine and more than seven thousand toxic substances can reduce tissue oxygenation, reducing their healing capacity. For this reason, cigarette smoking should be avoided before and after any medical intervention, including hair transplants.

In general, we recommend that you stop smoking at least two weeks before and two weeks after the transplant, and it is important not to cheat since consuming just two cigarettes a day reduces peripheral circulation between 9% and 55%.

Your hair transplant may be the reason to quit smoking permanently and improve your general health and the health of your hair in particular, as you will see an improvement in the shine, growth and appearance of your hair as your body detoxifies from nicotine.
