Found this salon online but couldn't find any details, such as location or number. Then realised it was in an Arcade on Bold Street (not seen from high street), and since its got great reviews I decided to check it out. A small salon run by an experienced lady, who did a great job. And for £10 you can't go wrong, but decided to tip since its so much more expensive elsewhere.
