Your hair was fine before you moved to Japan. Now it’s not. This is one of the most common things I hear from new expat clients. Here’s why it happens — and what I’ve seen help most across thousands of clients.
It’s Not Your Hair — It’s the Climate
The most common misunderstanding: new expats assume something has changed about their hair, or that they need different products. In most cases, neither is true. What changed is the atmospheric pressure on your hair — Tokyo’s sustained 80–90% summer humidity is genuinely different from what most countries experience, and most hair care products are formulated for lower ambient humidity.

The Timeline Most Expats Experience
- Arrival (any season): Hair behaves normally — Tokyo’s winters and springs are moderate
- First rainy season (June–July): Sudden dramatic change — frizz, volume, loss of shape
- First summer (July–September): Realisation that products from home don’t work here
- Year two: Either found solutions, or considering something more structural
What I Recommend, In Order
First: Switch your shampoo
Many imported shampoos contain silicones that can create buildup over time, which may make hair more reactive to humidity. Switching to a silicone-free Japanese shampoo is the simplest first step — results vary but many clients notice improvement within 4–6 weeks.
Second: Change your blowdry routine
Always blowdry completely — never air dry in Tokyo’s summer. Apply a heat protection product when hair is 80% dry, use a concentrator nozzle aimed downward, finish with cool shot.
Third: Consider acid straightening
For clients planning to stay in Japan 1+ years who find the humidity genuinely affects their quality of life, this is often the most meaningful change. It’s the only structural solution — everything else is management. Is it worth it for you? →
