Hair Loss in Japan: The Causes & Solutions!

The Hidden Secret In Your Drain

When I first moved to Tokyo it was a whirlwind experience. Naturally, I was stressed from the start and quickly had to contend with so many other changes, but things only got worse as I noticed one unexpected difference in my body.

I was losing so much hair! Clumps were lost almost daily after I arrived in the country. Experiencing hair loss in Japan can be hard to swallow for anyone, but as a 20-something female, it was beyond troubling. I researched my symptoms online (which is always problematic) but found very little information about what I was experiencing. I hadn’t had this issue in Canada. Was it Japan, or was I going crazy?

After scouring the internet, desperate for advice, I finally found a private Facebook group for women living in Japan. There, I found a plethora of people who were suffering in the same way I was. It turned out I wasn’t crazy, and I wasn’t the only one.

A Common Problem

Hair Loss in Japan: The Causes—and Solutions

We were all in our twenties or thirties, and it seemed impossible to me that our problems were completely independent of our new surroundings. How could each one of us have completely separate issues that sprang up as soon as we landed? More importantly, how were other people with the same hair loss problem supposed to find this tiny pocket of information in Japan without being members of the Facebook group?

I want to shed light on this stressor and help anyone who might find themselves in the same situation. This was something that almost cut my time here drastically short, and I don’t want others to feel alone.

So, Why Is My Hair Falling Out?

The answer to this could be equal parts simple and frustrating. Are you of European or Celtic descent? Unfortunately, this might put you at a predisposition to have more hair loss in Japan. Westerners tend to have much softer, finer hair. There are many reasons why our hair can freak out as compared to when we’re in our home countries. Let’s run down the list of some of the things that can weigh heavily on our tresses.

The Causes

1. Jet Lag

A lesser-known symptom of jet lag, outside the general tiredness and brain fog, is hair loss (who knew?!) This is likely caused by many factors, such as being at a high altitude, general travel stress and your body being thrown completely out of its regular rhythm. So, if you’re brand new to the country, it might not be time to panic just yet. Jet lag (typically) wears off at one to two time zones per day. For anyone coming from North America, that means it can take a week before the immediate effects wear off.

That being said, our hair tends to take even longer to catch up, so if you think jet lag might be the culprit, give it a couple of weeks to start getting back to normal.

2. Climate Changes

Not only does your internal clock take a beating when you first arrive, but depending on what time of year you land in Japan, the change in weather can also give you a serious beating. Summers in Japan are brutally hot and humid. Our hair is like our fur, so if we need to cool down, it tends to start shedding!

After speaking with a dermatologist here in Japan, I was told that my hair loss could be caused by dandruff, which is often caused by the humid climate (gross!). Dandruff is definitely something that happens to a lot of Westerners during the Japanese summers and winters.

It turned out that the level of severity of seborrheic dermatitis (the medical term for extreme dandruff), which would take to disrupt hair follicles, is—to spare you the worst of the details—intense. Far worse than the few flakes I was noticing. Still, if you have intense itching and flaking, you might want to speak with an expert.

3. Diet

There are a lot of changes to diet that come with moving to a new country. Japan has a lot of delicious foods, but what I didn’t notice right away was that, coming from North America, there tends to be less protein in Japanese meals. Also (at least in Tokyo), fresh veggies and fruits can be expensive and consequently, are more easily skippable. This is where things can go wrong, as nutrient deficiencies are going to manifest themselves in your hair and skin first.

When I first arrived, my diet changed a lot; I had to make a much more deliberate effort to keep the same micronutrients in my system that I was getting on a regular basis back home. Even if your diet isn’t necessarily unhealthier, a big change in food intake can still lead to a reaction in your hair weeks after the change has occurred. This can make it hard to pinpoint as a culprit for hair loss.

Some of the most important micronutrients for hair health are vitamins C and E, zinc, B-vitamins and omega-3 fatty acids. While omegas are fairly easy to come by in the Japanese diet (contained in fish and nuts), a lack of animal-based protein can decrease your B vitamins. Meat contains plenty of zinc as well, so we start to see how important protein is for hair growth. For my vegan readers, whole grains, seeds and legumes also contain these, but I would consult your physician to ensure you’re not missing any key nutrients.

4. Water

Where I come from, we drink natural, untreated water straight from the ground. Canada is blessed with a lot of accessible and fresh water. Japan, in general, also has very clean water. In a big city like Tokyo, however, it is heavily treated with chlorine to keep it free from contagions.

When I first arrived, I thought the water coming from my tap smelled like a swimming pool. The chlorine also turned my dyed, reddish-brown hair almost dirty blond in under a month, so it’s definitely heavy-duty. If your hair isn’t used to treated water, it’s likely going to take a long time to adjust to the change.

The Solutions

1. A Shower Filter

After reading through that forum I mentioned earlier, I realized that there was action I could take to slow my hair fall. The number one thing that was recommended was to purchase a shower filter. This helps to combat all those harsh chemicals in Tokyo water and can even help you adjust the strength of the water pressure so it’s more gentle on your follicles. I found this was a very quick way for me to address the issue in my drain every evening.

Savvy Recommends: I bought mine at Bic Camera for about ¥5,000, but you can also purchase the Cleansui Clean Water Showerhead online.

2. Hair Products

Here’s a big mistake people make, especially when they first move to Japan. If you don’t have hair similar to that of a Japanese person, then don’t use Japanese hair products, especially shampoo and conditioner. The Japanese hair care industry is (unsurprisingly) tailored to Japanese tresses. It’s made for thick, coarse, Asian hair. Because of this, it can be way too powerful and drying on foreign hair.

I highly recommend bringing products from home or ordering through websites so that you can make sure you’re not doing more harm than good in the shower. It also might be helpful to get something that is specifically for dandruff if you find you’re scratching your head more than usual.

Savvy Recommends: Lots of people swear by other dandruff hair products, but I prefer a more natural option called Petal Fresh.

3. A Silk Pillowcase

This is probably the thing that has helped me out just as much as the shower filter since I moved to Tokyo. Switching to a silk pillowcase is gentle on your strands, so I have stopped waking up to hair on my pillow after a night of tossing and turning. There is also an added benefit: silk pillowcases are supposed to be better for your skin! They can be expensive, at about ¥6,000, but I have found it a worthwhile investment.

Savvy Recommends: Silk pillowcases can be found at any linen store, but if you want an online option, check out this one made in Japan.

4. Mind Your Food

Diet can significantly impact hair. While you should check with a doctor before making any drastic dietary changes or introducing nutritional supplements, the right additions can really help to facilitate growth. Make sure you are eating foods rich in omegas and protein, such as fish, avocados, eggs and nuts.

Iron is also crucial for hair growth, and it is plentiful in dark, leafy greens. Another great supplement for strengthening your follicles is biotin. This is notorious for being difficult to get from foods other than eggs, but ask your physician about introducing it into your supplement arsenal. Any biotin supplements should do, and you can find them all over Amazon, Rakuten or even in Don Quijote.

5. Relax!

Moving to another country is, well, stressful! Especially if you are trying to find an apartment, a job and any sort of comfort from your old life. Things can be tense for weeks or even months and that can take a toll on your entire being. Plus, if you notice a lot of hair falling from your head, that can feed into more stress, so you get caught in this never-ending loop.

Try to remember that stress affects your hair slowly, but cuts deeper than most other factors. If you look at your life and think, ‘But I’m not stressed!’ then look back a few more months. You might remember being in a different time that is still following you around in the form of hair loss.

Savvy Recommends: There are lots of ways to relax and it’s going to be about finding what works for you. Starting a yoga and/or meditation practice will work wonders. Or, try introducing warm baths with fun bath bombs to help calm your nerves. If putting on some Netflix stand-up comedy or the newest anime release is what calms you, then do it! It’s about carving out the time in your day or week to address feelings of stress and doing what we know grounds us again.

6. Know When To Call In The Troops

Now, if a few months have passed and the problem is persisting, remember that hair loss can be a symptom of a more serious issue. This article can’t tell you if it is a cause for concern, so if you have tried all other avenues and it has been a few months of gradual thinning, or a large amount of steady thinning, it’s best to seek the help of a medical professional.

Start with a general practitioner, though it’s possible you will be referred to a dermatologist for further evaluation. Hair loss can be caused by a myriad of things (especially in women living in Japan), but it’s always good to err on the side of caution.

Things Will Get Better!

Hair Loss in Japan: The Causes & Solutions!

I am writing this article to ensure that, as people of all genders, ages, and ethnicities move into Japan’s four distinct seasons, they know they are not alone in their struggles. It’s not just you. It can be Japan. You are not going crazy. After a year of living here, multiple trips to the dermatologist, and adjusting my haircare routine, I have quelled the worst of the hair fall.

It took me a long time to find the products that were right for me, so I suggest experimenting with your routine and trying to address the main issues we tend to face here as foreigners. A little time and TLC will most often resolve the issues, so try not to stress yourself out more by dwelling on them. Dwelling on them can only make them worse.

Just remember, you’re not the only one experiencing hair loss in Japan, and it will be okay. Focus on all the great things Japan adds to your life, not the losses on your scalp.
