I got my hair done December 2008. 2 Touch ups per year. The roots can be a pain when they grow back however I am lazy and do not like dealing with my hair so it was worth it. I have very curly hair, not really sure what type, but humidity and I did not get along. When my hair was curly and dried the volume would be enormous. While I miss my curls at times, this just seems easier for the moment. Maybe one day I will let the curl back, but for now just enjoying wash and go.
