I have been going to Sonia at Picasso Salon for the past 7 years. I have naturally curly hair and absolutely hate it. A friend had thermal straightening from Sonia and after seeing her hair continue to be straight 6mths after treatment- I had to get it myself! I spend 4 hours with Sonia, one time a year and my hair is amazingly straight. I love love love it! I recommend Sonia to all my friends for any type of hair expertise or wizardry. She is abso-freakin-lately AMAZING!
