I am a local singer/songwriter as well as musician (been a guest artist on television), who has been trying very hard to grow my hair out after keeping it fairly short for many years. I had finally come to the point where I desperately needed help as my hair is very thick and curly. I am also very protective of my hair as I don't want to ruin my efforts of two and a half years (though I have had it trimmed from time to time).
Pros: Very knowledgeable of latest styles
Cons: May be a little pricey for some (call to find out)
