Have been to Hair By Fairy before and will definitely go back again - the waxes are always quick and as pain free as they can be, plus the waxer is lovely!
I had my under arms waxed and I was in & out within a few minutes. This is the 2nd time I've been and have seen 2 different people and they've both been good.
Lovely lovely therapist and buzzy little salon. Not a luxury place but perfectly clean, friendly and comfortable. Great prices for central London. And again, the therapist was brilliant. Made it all a breeze.
