Hair

I have the WORST hair. For one reason I have been coloring it since I was in the 7th grade and my mother has some think course hair which I inherited. There is this new thing out called the Brazilian Blowout, it is supposed to make your hair smooth and shiny and soft and just wonderful for up to 5 months. I want to do this and have seen one persons hair with it done and it looks great but have any of you had it and if so did it work and was it worth the $$$ you forked out to get it done?? I think the lady that I talked to said she paid $240 to get it done!!!! YIKES that is a lot but for 5 months of great hair I think it may just be worth it!! My hair is the longest it has been since my Senior year in high school and I want to shave it off but I waited a long time to get it this long so I want to make it look good instead of the daily thick rats nest!!
