Most people who notice their hair thinning blame age or genetics. But a common, everyday habit may be accelerating the process – and many don’t consider the connection.
Smoking, long linked to serious diseases, may also be connected to the speed at which hair thins, according to hair specialists at UK Hair Transplants. Research suggests a correlation between smoking and an increased risk of both hair loss and premature graying.
Studies demonstrate a correlation, but not a proven causal link. A study published in the Journal of Cosmetic Dermatology found that male smokers had an 1.8 times higher risk of developing male pattern baldness compared to non-smokers. Another study, in the Indian Dermatology Online Journal, showed smokers were 2.5 times more likely to experience early graying.
Male pattern baldness is fundamentally strongly genetically determined and very common. However, experts believe lifestyle factors can influence how quickly the process develops. One possible explanation is that hair follicles depend on good blood circulation to receive oxygen and nutrients. Smoking can impair blood flow, which in turn can affect the different phases of hair growth. Hair quality can also be affected, with increased dryness and a greater risk of breakage.
Reduced blood flow due to smoking and nicotine-containing products can also lead to slower wound healing and an increased risk of infection, impacting hair transplant success. In rare cases, smoking can even cause tissue necrosis, or death of the tissues.
Normal wound healing involves four crucial steps: blood clotting, inflammation, growth and rebuilding and strengthening. These steps are observable during hair transplant surgery. Smoking interferes with these processes, hindering the body’s natural repair mechanisms.
A representative for UK Hair Transplants stated that stopping smoking is one of the most beneficial actions someone can take to improve their prospects – both for their general health and for the well-being of their scalp.
At KSL Clinic, surgeons recommend patients stop smoking at least five days prior to surgery and abstain for at least two weeks afterward. Treatment Rooms London advises ideally stopping smoking before undergoing a hair transplant to optimize the body’s immune system and healing ability.
While a smoking cessation is beneficial, sudden or patchy hair loss should always be investigated by a doctor, as it may be due to underlying medical causes.
Beyond smoking, other factors to avoid after hair transplant surgery include alcohol consumption, which can cause dehydration and increase blood pressure, reducing blood flow. Direct sunlight exposure should also be avoided for two weeks, and hair dye should be avoided until the scalp is fully healed and a doctor advises it is safe.
