Where to find hair color?

[untmdsprt]

I'm looking for brown hair color to cover my grays. I'm currently living in Yokohama, and don't know if any of the hair color kits will work. Can anyone tell me what I can use? I have thin medium brown hair for a white woman.

Thanks! Oh, please use hiragana, katakana and or kanji so I can find the product. Use of romaji is practicaly useless here in Japan!!

most chemists ( くすりや　薬屋) seem to have it but not sure how good it is for western hair - should be ok as Asian hair being thicker is much harder to dye.

Alternatively most hair salons will be happy just to sell you product. Or try somewhere like Foreign Buyers Club. Other options could be places like CostCo or if you can get up to Tokyo there is an American Chemist in Maronouchi that could probably help out.

Update: I did buy one of the Loreal products at Donki Hote, and while it didn't cover the grays, it didn't hurt my hair either. I left it on for 10 min though. The instructions said to leave it on for 20 min. I may try it for 20 min and see how it does.
