Do Doo Gro products REALLY work?

I have a little fro right now after cutting my dreadlocks off 2 years ago so I%26#039;ve been sporting the short fro look for a while but I want to grow out my hair now. I want it be natural still but long, you know like when it%26#039;s just long and curly and soft and flowing! : P So who%26#039;s used Doo Gro to grow out their hair and did it work? What are other products that grew your hair? When did you notice results? Thanks all!! ; )
