I have some dreads that are not congos that fork into two dreads. I have a few that started as one, became two, then back to one again. They just do various different things. Granted I'm almost a year in the process. It really changed every time I was them.
"The salon says I have to come back every 3-4 weeks for more work, but I don't know what that's all about." it's about $$$$$$ they want your $$$$$ sorry sweaty but you got burned. my advice is take care of them/maintain them on your own, don't let them rip you off anymore. i hope the chemicals didn't give them a bad start but i think likely they did.
duhhh sorry i read the original past halfway and got a little emotional and replied before i saw the thread was older and had many replies, and i didnt read any of the replies god i hate when i do that!
