Helmets or headgear do not cause permanent baldness or hair loss. However, hair thinning by helmets may occur if they’re poorly fitted or unclean, trap heat and sweat, and are worn over tight hairstyles. These factors may also cause breakage, scalp irritation, or traction-related hair shedding.
This blog will answer questions like: "Does a helmet cause hair thinning?", what symptoms you can identify it , and what you can do to protect your hair.
How do helmets and headgear cause hair thinning?
Wearing a helmet while riding your bike, scooter, or cycle is necessary, because safety first! But many people don’t realise the impact it has on their hair. In fact, any form of headgear, if worn for a long time, can make your hair appear flatter and greasier. This naturally makes one ponder: ‘Does wearing a helmet cause hair thinning?’ Although helmets do not cause permanent hair loss, prolonged use can lead to the following factors that cause discomfort to your scalp:
Traction and pulling stress on hair follicles
Helmets are designed to sit snugly on your head for safety. But when your hair is constantly compressed inside a helmet, it reduces blood flow to the follicles.
The helmet-induced tension and pressure on the hair are primarily concentrated on your frontal hairline, crown, and temple areas, which are most prone to genetic thinning. So, while mechanical stress doesn’t cause pattern hair loss, it can worsen hair shedding or breakage in areas that are already experiencing thinning.
Friction and repeated mechanical damage
The inner padding of your helmet rubs against your hair repeatedly while riding a bike. This may occur especially when you’re riding over bumps, turning your head, and wearing a helmet during long commutes. This friction may give rise to traction alopecia-related hair loss over time.
Heat, sweat, and scalp infections
Most helmets have no ventilation at all. So, the heat and sweat that get collected on your scalp make your hair shafts softer and more vulnerable to breakage.
Although sweat acts as a coolant for your scalp, excessive levels of it increase the lactic acid and urea, which can disrupt your scalp’s pH levels. It can lead to greasiness, itching, and buildup, causing conditions such as:
- Folliculitis (skin condition resulting in inflamed hair follicles)
- Seborrheic dermatitis (itchy and scaly patches in oil-rich areas on the scalp and face)
- Tinea capitis (ringworm of the scalp)
Your scalp’s moist environment allows bacteria or fungi to thrive causing dandruff and other scalp irritations.
Helmet hygiene
By the end of every day, your scalp accumulates dirt, dust, oil, sweat, and dead cells. If you share helmets or do not wash your helmet every now and then, these substances transfer to your scalp, affecting the growth environment of your hair follicles. Your scalp may even get allergic reactions from the synthetic material of your helmet’s inner padding.
Headgear that can cause hair thinning
Not only does a helmet cause hair thinning, but tight headgears, like the following, worn for long periods can also build pressure on the scalp and hair:
- Cycling helmets, sports headgear worn during cricket, motorsport, riding, or hockey
- Industrial helmets and construction hats
- Tight hats or caps, beanies, or headbands
Signs that your helmet or headgear is causing hair thinning
Since wearing a helmet is a routine part of your life, most people don’t recognise hair thinning until it becomes glaring. Here are some early symptoms:
- Finding strands of hair in the helmet’s inside padding
- Having a greasy, itchy, and irritated scalp
- Finding visible redness or small pimple-like bumps on the hairline
- Noticing your hair looks noticeably thinner and scantier overall
Hair care tips for managing hair thinning by helmet
Helmet-related hair thinning is not immediate; it happens over time. So, if you’re alert to spotting the early signs, you can take up timely precautionary measures to protect your scalp and hair. Here are some daily hair care tips to prevent hair thinning by helmet or any headgear:
- If your helmet leaves marks on your forehead, it means it’s too tight. Opt for a helmet that fits just right, not too loose or not too tight.
- Wear your hair down and tie it into a loose braid or ponytail, so the helmet’s constant friction doesn’t tug at your follicles.
- Wet hair needs more care than dry hair. The hydrogen bonds that give your hair structural strength are temporarily broken when you shampoo, making the hair more susceptible to breakage. Wet hair also traps moisture against the scalp, creating a damp environment which we want to avoid. So, never make the mistake of putting on your helmet over wet hair.
- Clean your helmet regularly. If your helmet smells stale, know that it is becoming a breeding ground for bacteria. Wipe the inner lining with a mild anti-microbial solution at least weekly if you wear your helmet daily. Nowadays, helmets come with removable and washable liners that you can use to your advantage.
- Wash your hair with a gentle shampoo like Traya’s Defence Shampoo after every sweaty ride to maintain a healthy scalp environment.
Hair thinning by helmets is just one of those problems that develop quietly. But once you know the underlying condition, you can adjust your hair care routine and tackle hair problems at the root.
Frequently Asked Questions
1. How to prevent hair loss due to a helmet?
It can be avoided by wearing a cotton or silk helmet liner, cleaning the padding of your helmet frequently, and letting your hair dry before going on a ride.
2. Is it better to have a tight or a loose helmet?
Neither. Helmets should fit snugly and evenly around your head. An overly loose helmet is a safety hazard, while an extremely tight helmet can restrict airflow.
3. Is hair thinning by a helmet permanent or reversible?
Wearing a helmet daily can result in hair thinning, but not permanent hair loss. Helmet-induced friction puts the hair follicles under stress, but doesn’t entirely damage them. So, if you spot the symptoms early, you can reverse hair thinning.
4. Who is most at-risk for helmet-related hair thinning?
Not everyone who wears a helmet undergoes hair thinning. Based on the above-mentioned headgears, individuals who are at a higher risk due to duration, frequency, and usage are as follows:
- Delivery riders
- Daily commuters
- Sports players
- Professional athletes
- Construction workers
- Individuals with pre-existing scalp conditions
5. Can switching helmets stop hair thinning?
Switching to a better-fitting helmet with cleaner and smoother interior padding can reduce hair thinning. While the helmet still causes friction, you at least don’t have to worry about using an unclean one.
