Well my dear, they look perfectly fine for 3 week old dreads. The T&R that you did are not dreads at all, they are the blueprints of where you wanted your sections to be. The frizziness is normal and will be there for perhaps a months, different for other people. Your sections will loosen, maybe completely fall out, and this needs to happen so that your hair can go on its journey on becoming a dread. Those sections will loop, zig zag and shrink, becoming dreads. I am over a year into my journey and do not have mature dreads yet.
Those sections will turn into the thickness of where the section meets the scalp. (Recommended scalp section is 1 inch or under....unless you want fat boys). So to get to that thickness, they have a lot of action to do.
Believe it or not, but doing T&R actually sets you back a step because they do need to loosen first, with neglect/free form method they are already loose.
Just wash & separate any sections trying to join together. That is all you have to do now. You don't need to worry about how they look, you don't need to worry if your don't look like someone else s at the same timeline, you don't need to worry when it all falls out.....you don't need to worry at all...just sit back and enjoy the ride. That is the great thing about growing dreads, enjoying the amazing process along the way. Take weekly pictures and you will see the changes each week.
Peace
