Sunscreen Advice for Bald Bicycle Riders

Summary: Sun exposure through vents is a problem for bald riders and some others. It is not limited to men. Here are some interesting adaptations to avoid funny tan lines.

Below are some email messages from bald riders and others who are concerned about helmets and sun protection. Email us your solution to add to this page. We do not post ads, just advice from other people with hair-free heads!

One emailer says his dermatologist finds that bike riders are high on the list of skin cancer victims. That would include all exposed body locations, but if you are reading this page the head is an important one for you. Many of our inquiries come from Australia and New Zealand, where a hole in the ozone layer made sun protection more critical than ever.

Sunscreen users might want to try a spray-on sunscreen like Kinesys. It is easy to apply, but like any sunscreen you will probably need a sweatband to keep it out of your eyes, since it is designed to migrate to cover all skin.

Smith Optics has a helmet line now with a liner that includes bundles of plastic straws called Koroyd. Instead of open vents, you have Koroyd's tubes partially blocking the sunlight. You can check them out here. They might just leave you with burn dots instead of whole vent outline--we don't have any reports yet.

There are a few manufacturers who started to think about this problem. They design thin hats that let the air flow and are meant to be worn under a helmet. Also, some manufacturers of uv protecting swimwear claim that their swimming hats are also good to wear under a helmet for biking and let the air flow.

I was reading about bald riders and helmets on your site. All the info pertains to tan lines. My problem is heat rash. I get a terrible heat rash from wearing a helmet in warm to hot conditions. I have tried a helmet liner and that does not work. I have to go to work looking like I have hundreds of small pimples on my head. It makes me want to quit riding even though I love riding my mountain bike. I have seen a dermatologist who says that there is basically nothing they can do. This is a recent development over the past couple of years and the doctor just says, "well our bodies just change as we get older" I can't believe that I am the only one with this problem but cannot find any good information pertaining to this subject. Any advice?

During the hot and cold weather I wear a do-wrap under my helmet. I shave my head. So I find the do-wrap gives the helmet a better fit than without. The helmet does not move around with the do-wrap on. I do have to readjust the helmet when not wearing the do-wraps. When I'm not wearing a do-wrap. I use a product called Sweat GutR to prevent sweat from getting in my eyes. The Sweat GutR does not interfere with the helmet at all. Its a head band that ducks the sweat to the side of the head away from the eyes.

A fine-mesh microfiber cloth or netting installed flush to the inner hard surface of a helmet (attached under the soft-foam strips with glue or double-sided tape) will protect the scalp from the sun's rays. This raised-above-the-scalp netting allows complete ventilation of the head while protecting it. One way to get this netting is to cut a piece from an old breathable bicycle shirt.

June 26, 2007, KLMitchell Try powder sunscreen. Colorescience is one of many companies who sell powdered sunscreen (though not the cheapest, I'm sure - do an internet search for powder sunscreen & see what you can find). It works great, and won't be greasy on your scalp. It can also be used by people with thin hair with better results than a greasy lotion.

June 15, 2005, Christopher Garrett (caution: apparently has hair!)

I like having one because it keeps the liner cleaner and the helmet does not pull your hair.

I would check out www.dowrap.com They have a nice variety of under helmet head wraps, skull caps etc. Their SweatVac products are all performance fabrics that offer excellent sun protection and keep the sweat from dumping into your eyes/glasses. They're basically made of the same fabric that a good jersey is made from so they actually help to keep you cooler. They also have some great cold weather stuff and some cool women specific head wear too.

Check out Do Wraps at their website. They make helmet liners for sweat absorption and sunburn protection. Made for bicycle, motorcycle, and other sports helmets out of a variety of high quality materials they come in different styles and colors.

I tried do-rags and found them too hot and awkward. They usually left red lines on my head after a ride where the seams were. I tried sunscreen, but it left me with a yucky residue and sometimes a rash/pimples. I tried using electrical tape to cover the holes where the sun entered. That was a nice cheap solution, but looked awful and was not elegant.

I wrote every helmet manufacturer I could and was told there are no appropriate helmets and no plans to address our issue (Even though over half of the guys responding from the helmet companies said THEY had the same problem!)

I DID hear a rep tell me about one helmet, and saw a picture. It was a Limar 707 in blue. Even though she provided a U.S. distributor, I was unable to actually find anyone who could sell me one. The shell had the vent indentations visible, but not cut out. Price was supposed to be around $130, I think.

After watching Le Tour I figured I would try a time trial helmet. Heck, if it was cool enough for a pro rider, I d give it a try.

I found a Louis Garneau Prologue Helmet at Nashbar. It was even on sale from $120 to $90, though that is more than I ever spent on a helmet before. I have used it for 2 weeks now and highly recommend it. (No business interest, just a consumer) YMMV

It comes in 4 cool styles/colors and has NO VENTS on the top. There are 3 small vents in the front, but I think they are small enough and horizontal, so direct sunlight is not an issue. It comes with a clear visor, but I had to remove it because it interfered with my eyeglasses. It has a bit of a tail in the back. Even though it doesn't have lots of vents, I have found it to be ok so far in 80+ degree weather.

I hope this helps.

BHSI note: We don't recommend helmets with long tails for normal road riding. When you hit the pavement that tail can push the helmet aside. Using foam or solara on a conventional helmet's top vents should be a better solution.

Wouldn't you know a helmet company guy would suggest this solution to funny tan lines on a "hair free" head? By alternating between two or three helmets (or four or five?) you can mitigate the funny tan marks. This method does not really work for touring unless you want to haul extra helmets.

Wear a "dew rag" under the helmet. Not only for sweat absorption, but also those funny tan lines.


I wear a 10 inch square of Solara brand sunscreen fabric under my helmet.

I use an equestrian helmet when bicycle riding, because it provides much better protection from the sun than any bicycle helmet I can find. I can't recommend this for everyone, because the safety standards are different. The local horse supply store has several styles of equestrian helmets. Wish someone would test them to the bicycle standards, so we would know if they were okay.

Handi Wipes (those woven cloth-like kitchen wipe-ups) are a cheap and effective helmet liner for bald heads. Buy them in a pack of six in grocery stores or anywhere household supplies are sold. Fold the Handi Wipe in quarters to make a 10.5 inch by 5.5 inch rectangle and lay it in the top of the helmet.

Handi Wipes are woven, which allows the air to flow through, are very absorbent, and dry almost instantly when rinsed and squeezed. On long bicycle tours, at rest stops I rinse the Handi Wipe in water, use it as a wash cloth to freshen up, re-rinse, and then put it back in the helmet slightly damp for a cool start up. I also carry one in the underseat bag for bike cleanup.

I use a product from the motorcycle world. It's called a Texas head skin. It's a very absorbent cloth material that is shaped to fit your head. One problem is the thickness. Although not all that thick I had to remove my sizing pads for a correct fit. They work very well but unfortunately they are hard to find.

Agnes Burns, a member of the Elbow Valley Cycle Club, makes helmet liners for folicly challenged folk like her husband Bill. The liners are stretchy (one size fits all) and have a neck flap. She sews them at home in white grey, blue and black coolmax fabric.

I am not balding but wear one because it wicks the moisture from my brow and scalp. A quick rinse under the tap, a wring and its ready to go again. Baldcap photo For more information, contact Agnes at bagnes@cadvision.com I have no commercial interest in what Agnes does with her sewing machine--just a sincere interest in helping helmet wearers be more comfortable and sun safe, balding, thin hair or otherwise.

I have been experiencing this more often--especially now that I keep my hair very short (don't have the guts to shave it all the way).

Having tried various sunscreens--the "dry" spray-on types definitely seem to work best--and having over-heated using cotton bandanas and cycling caps, I decided to look for an alternative.

Several companies make CoolMax (or equivalent) "do rags" that work wonderfully. All the major catalogs (Performance, Nashbar, Excel, Colorado Cyclist) carry them. They are light, wick sweat, prevent "run-off," and definitely prevent vent-tan lines. They are shaped with built-in ties and neck flaps, so you don't have to do any fancy folding to put them on.

Happy Trails!

Matt Brown

My husband and I use Solumbra clothing for nearly all of our outdoor activities - light weight, comfortable, quick-drying, and sun-proof. Their under-helmet "drape" is great for protecting one's head (my husband's) and neck (both of ours) at the same time. The material is so light it interferes negligibly with air flow, and its wicks well. The only problem is that the straps from the helmet hold the drape down somewhat, closer to one's face. We don't worry about drawing attention. We wear drapes all the time while hiking, and we are used to drawing attention riding our recumbents! I highly recommend their pants, shirts and gloves as well. They are at sunprecautions.com.

Subject: coolmax bandanas

For those of you having trouble growing grass on that busy street, check out the "headsweats.com" website. They have cotton and coolmax headsweats and sweatbands and other products to take care of the sweat and the tan lines. The built in sweat band reduces the sweat in the eyes problem and I don't find them too hot. I live in Cincinnati and the hot humid weather is never a problem. I don't ride easy either and I sweat a lot.

good luck.


Subject: Sunburns through helmet vents
From: "Ellen F. Mac Garrigle"

Don't laugh, guys -- it has happened to me on more than one occasion, and I (unlike my husband) am not famous for a sparsely-populated area on top of the scalp. I have also seen some truly interesting tan lines on gentlemen with the Patrick Stewart/Michael Jordan look.

I have the lovely (hah!) gift of thin hair with a part that happens to run right underneath one of the vents on my Bell Image helmet. Most of my favorite rides around DC are east-west-east trips, so if I leave late morning, by the time I turn around I have been riding right into the sun for two or three hours during the Prime Tanning Rays period. And don't even ask about tours where I am riding in more or less one direction for the entire day (it's burned skiing and swimming, too, but cycling is the worst).

Its hard to put sunblock on your head (of course, its not like your hair looks great after hours in the helmet anyway), but I have found two possible solutions:

There is (don't laugh) a spray-on sunblock. They sell it at REI I think and I've seen it other places. My husband told me about it because it worked for him. If I spray it on the part, no burn, but it's expensive and I'm not sure how sweatproof it really is.

Fold a bandanna in quarters and put it in the top of the helmet (under the vent, over the part/bald spot). Additional advantage is that you can pour water on it to keep cool on a hot day.

I have not found another helmet I like as much, and the part won't move (short of getting a perm), but the rag on my head, while odd-looking when I take off the helmet, is not nearly so odd as peeling sunburn on top of my head.

Maybe my head is a little more sensitive than most, but maybe this will help someone...


I shaved my head two weeks ago. And noticed that I started getting funny tan lines from my helmet. I thought to myself, I've worn this helmet for how long now? And never needed it (I never crash). Do I really need to wear it? And put up with these tan lines? I decided on wearing a thing called a "flydanna" under my helmet. It's kind of like a bandanna that's made to tie in the back. Good thing I did. Two days ago while road biking, I went down at about 35 mph on Chevy Chase Dr. in Glendale, CA. I shattered my collar bone (R. clavicle), and shattered my helmet too. My head had a slight bump on it. The doctors, upon looking at the remains of my helmet, said if I had not been wearing that helmet I would be in a different part of the hospital. The Morgue.

The last time I bought a helmet, I wore a bandana to find a good fit while wearing it. I now don a bandana under my helmet in all seasons. It helps me keep warmer in the cold weather and protects me from scalp tan lines in sunny weather. More importantly, since I perspire profusely from the head with thinning hair, it also absorbs the water in warm to hot weather and keeps it from running down onto my sunglasses. The bandana also adds a comfort layer between my scalp and helmet. However, I would love to find bandanas made of polypro (instead of cotton) to better wick away the moisture -- anyone suggest a source?. BTW, to wear the bandana as a "hat" under a helmet, fold it in half to form a triangle and then tie two corners behind your head and secure the third corner which covers the top of the head. Finally, when resting during a ride, I usually take off my helmet. The bandana covers what is left of my thinning hair and hides the dreaded matted-down helmet-hair effect. Chicks love the look -- or at least I imagine they do!

I use Coppertone Sport SPF 15 or 30. It dries quickly and does not cause my eyes to burn when I sweat

Josh Berger, M.D.

I use Oil of Olay "Daily UV Protectant Beauty Fluid", SPF 15, on my upper face. It doesn't sting the eyes at all (for most people). The only problem is the "beauty" part, I've been using the stuff for years.....no sign of beauty yet.

From: Mike Leung

What brand of sunscreen can you use that doesn't blind you when your sweat streams it off your scalp (or forehead in my case) and into your eyes? Anything I use really stings.


Mike, we've had great luck with "Aloe Gator" SPF 40, Waterproof, Non-Greasy, Does NOT Sting Eyes. This stuff is expensive, so I use it only on my face while reserving the "cheap" sunscreen for all other applications.

The father of a friend relied upon what he called "scotch hair" to keep from getting sunburned through the vent holes. He simply used a swatch of newspaper - the "scotch" adjective reflecting the price of the product. I tried it myself when caught on a long ride in the sun early one season. (Probably, June or July since I live in Oregon.) I found, however, that newspaper does tend to leave a gray tint, so I now use a thin single-layer paper towel torn to cover only what is needed. I find it restricts airflow only slightly, is cheap, readily available (try McDonalds or Burger King), doesn't cover too much (like a bandana), and doesn't leave any residue on the helmet or pads. In the words of Dave Barry, I am not making this up.

John Replinger
Portland, OR

As another "follicularly challenged" cyclist on this list, I am also interested in any well-designed "no-hair-net" helmet. My own current favorite is a Z Leader 1991 "Avanti" model, which I recently found in a local discount warehouse. This is a Canadian-made, Snell B-90 certified helmet, with four small low vents in the front and three tiny vents in back - the top of the helmet (where it really counts) is solid, and I am satisfied with the ventilation.

Unfortunately, this helmet seems to be out of production. Leader Sport Products, the manufacturer/importer, has apparently dropped its helmet line and now concentrates on protective eyewear. [They do have a website at www.zleader.com - if you want to check with them about any surplus stock they might have.]

Also unfortunately, the current trends in helmet design seem to favor more vents (and less protection - at least for the alopecic riders).

Now that Winter is upon us, I will break out my trusty old Bailen Bucket, which has no vents at all, and an expandable head band to adjust to any cap underneath. Alas, the Bailen is also unavailable (and is not to be trusted according to the good folks at the BHSI - before you succumb to any retro-envy).

It has occurred to me that another possible source for input on this topic might be the organizers of large fund-raising rides for cancer research [eg: the American Cancer Society, the Pan-Mass Challenge, etc.] since many of their riders are chemotherapy patients and are thus (temporarily) hairless. I suspect they've had more experience dealing with this question than any other group.

I'm well established in the ranks of the "follicularly-challenged". For the past several years I have simply used a bandana folded diagonally and snugly tied, with the odd vertex tucked under the knot at the back. This not only completely shields my cranium from the sun, but helps reduce (or eliminate) the amount of sweat that otherwise would trickle and drip into my eyes. When doused under a cool faucet, it also provides a "swamp cooler" effect, helping me stay cooler.

Well....I have no hair. At all. I find sunscreen works just fine - look for one that bills itself as "waterproof" or "won't wash off." One side note - I generally end up buying an extra small size helmet - no padding in there to take up the extra room.

Pete "Clean Head" LaVerghetta

Re the problem of too much sun through the vents, a friend of ours glued some screening on the inside of his helmet to (partially) block the sun and still get air flow. He used the type of screening that is used for patio covers etc.. It can be found in garden supply centers as well as building supply centers. In most cases you can choose the amount of blockage you want. He says it does the job of maintaining ventilation while blocking most of the sun. It apparently worked well for him on our September trip to the Loire Valley and Beyond since he reported no problems with sunburn on the top of his head after 9 days of mostly sunny cycling.

Gene & Bobbi, The Tandem Turtles

I have tried many kinds of sunscreen, and the combination of sweat, the movement and rubbing of the helmet, etc. cause this to not work at all. FWIW, the best of the bunch is a product called Hot Heads, which is a non-greasy, alcohol based spray on sunscreen, but even it comes off to some extent. I do use it in general, however, in that it is a relief to not have the greasy stuff all over! This leaves me, and most other balding riders with bandannas over the head, which adds heat.

I have tried, in addition, helmet covers -- hotter than the bandanna, cycling caps worn backward -- also hotter. A company named Solumbra makes a helmet cover with a neck flap, which has a distinct "Sheik" look. I just could not bring myself to try that!

i got to agree with all the other bandana sporting bikers out there: sun protection, evaporative cooling, and salt water retention/eye irritation deterrence. i've been using one for 6 years now and find it uncomfortable to ride without one. i'm not sure about george kollar's observation that the chick's love it, but it has given this tall skinny white guy just a little measure of cool. on a trip down the east coast several years ago, a teenager i met positively noted my 'do rag'
