You can increasingly read online that 5G networks cause hair loss, especially in men. We decided to check what science actually says – without fear and without exaggeration.
Why do men lose hair more often than women?
The most common form of baldness is androgenetic alopecia. In men the key role is played by the hormone DHT (dihydrotestosterone), which gradually shrinks hair follicles in genetically sensitive people. Besides genes and hormones, age, stress, diet, the thyroid and some medicines also matter.
As the chart shows, hair loss increases with age – much faster in men than in women:

How mobile technology has evolved
In only about thirty years we have gone from the first digital mobile phones to 5G. Our devices are ever closer to our bodies – in our pockets, by our heads, under our pillows.
What does science really know about 5G and hair?
At higher frequencies, 5G uses so-called millimetre waves, which are mostly absorbed in the surface layer of the skin. That is why some researchers ask whether they could affect skin and follicle cells over the long term. Laboratory studies have shown that electromagnetic fields can influence some processes in hair follicle cells, such as inflammatory signals. But these are early results on cells, not proof that 5G causes baldness.
An overview of the main mechanisms of hair loss and what we currently know:
| Mechanism | Link to hair loss | Evidence for 5G |
|---|---|---|
| DHT and androgen receptors | Well established in androgenetic alopecia | Not confirmed |
| Follicle fibrosis | Can cause irreversible hair loss | Not confirmed |
| Oxidative stress | Being researched in follicle biology | No proven causal link |
| Oestrogen and sex differences | Can affect the hair growth cycle | No confirmed special protection from 5G |
In short: today there is no evidence that 5G causes hair loss. At the same time, science is only beginning to study the long-term effects of all-day, everyday exposure to devices – and such exposure has existed for only a few years.
What can you do today?
- Take care of the causes that are proven – you can't change your genes, but you can manage stress, sleep and diet.
- If you notice increased hair shedding, see a dermatologist – early treatment of androgenetic alopecia gives the best results.
- Don't carry your phone against your body all the time, and don't sleep with it next to your head.
- Build small habits of more mindful technology use.
For those who want an extra step, there are HSC Cards – a small, simple habit for anyone who wants to live more mindfully with the devices they use every day. The card goes on the back of the phone and can be a promising step in protection in an increasingly wireless world.
Conclusion
Hair loss in men is most often caused by genes and hormones, not by mobile networks. Still, technology surrounds us as never before, and answers about long-term effects are only now coming. So it pays to be informed, sensible and careful – without fear, but without naivety either.
Live better. Every day.
