I know that this has already been talked about in other threads but couldnt work out how to comment.
Yesterady I had my hair cut at Corner Salon in Bangkok (google hair dresser bangkok) and its the best cut Ive ever had in my life! I was a little worried when I went in there as I wasnt sure the lady knew exactly what I wanted (I'm very particular with how I like my hair cut as its curly) but the end result was awesome!! its the longest haircut Ive had in a while aswell they actually take time with you not pump you through in half an hour. Highly recommend this place and it only cost 300 Baht.
