Absolute best blow wave for curly/frizzy hair!

Thuli at Cresta blow waved my long curly hair and it stayed pin straight for 6 days. I didn't even have to fix it in the mornings with my hair dryer. Through the rain and humidity in Johannesburg my hair remained dead straight! She is very friendly and ensures all pieces of my long curly hair stayed straight? Thanks Carlton and Thank You Thuli!
