I've never had better hairdresser than Slawek. He helped me to deal with my wavy hair offerinfg special hair treatment and than unique haircut.
I highly recommend hair treatment (with herbs and oils) and brazilian blow dry (expensive, but worth it's price).
Top-notch service. Extremely friendly staff.
Definitely the best experience in this part of London, by a long shot, and I have probably gone everywhere.
I got the best haircut I have had in years. Good stuff.
