Are vaping devices harmful to hair?

The dangers of smoking are well known, yet many people still smoke, and many try alternatives to the cigarette in an attempt to give up, or at least to protect themselves from the harmful substances tobacco contains. Vaping devices and electronic cigarettes are very popular today among men and women of all ages; the liquid these devices contain, however, also holds substances that are dangerous to health, as well as nicotine. Inhaling these substances can also contribute to hair loss, and here is why.

Are vaping devices harmful to hair?

Smoking damages the hair

Many factors can contribute to hair loss: genetics, stress and hormones such as DHT (derived from testosterone). Each of these variables has effects on the hair follicles, which sit beneath the skin and act as the foundations from which the hair shafts grow. Most patients know that genetics, stress and DHT can send hair follicles into premature rest or cause their miniaturisation, meaning the thinning of the hair and then the halt of hair growth. Many are surprised, however, to learn that certain habits such as nicotine use can be just as damaging to the health of the hair. Nicotine causes vasoconstriction and reduced blood flow, a side effect that occurs throughout the body after use. In the scalp, reduced blood flow can do considerable harm, and to hair growth in particular. Blood supply is vital to the health and growth of hair follicles. Without sufficient blood flow, the follicles are deprived of the oxygen, nutrients and growth factors needed to maintain a normal hair growth cycle.

Do vaping devices and e-cigarettes cause hair loss?

Current studies on the subject need more data and more time before they can be relied upon. Preliminary research suggests, however, that these devices contribute not only to hair loss but also to cell damage and to a condition called bronchiolitis obliterans.

Researchers believe the nicotine these devices contain affects the human body in the same way as cigarettes and chewing tobacco. That means reduced blood flow in the scalp, which threatens the health of the hair follicles.

Deciding to stop smoking can considerably reduce the risk of cardiovascular disease and events, of cancer and of respiratory disease. Vaping devices and electronic cigarettes contain no tobacco, but research does not have enough data to assess the risk of e-liquid use. As for nicotine, its harms are the same as with the cigarette, so it is worth dropping the habit if the health of your hair concerns you.
