I Need A New Shampoo

 I have long hair but I'm trying to grow it out longer, my hair becomes so nasty dry and dead at the end, that everytime I go to the hairdresser she says she has to cut off inches of my hair because it is so dead. This happens because I can't find any shampoo that makes me hair feel "normal" and soft. I've gotten to the point where I don't use conditioner. I use a Pantene Pro-V 3-minute leave in conditioner - once a month, and that seems to hydrate/condition my hair for a while but it conditions it without leaving it too oily or too dry.

I just live with it being super dry and brittle and breaking everywhere.

I swear I've gone through every brand of shampoo and condtitioner at the store.

Since I was little my hair has always been thick and it's so thick that it never curled or straightened or did anything for that matter. Also when I was a child I always had to rinse my thick hair with vinegar and/or lemon juice.

I've always had a hard time finding shampoos..I don't think I've ever settled on just one.
I've now grown sick of wasting my money on shampoos and conditioners that don't do anything for my hair.
They either dry it out or make it too oily...there is no in between. I don't use alot of conditioner either. I've experimented and used alot and a little, and I can't get the results I want.
I battle with my hair so much to get it to do anything.


Natural shampoos have always been the best because there are no chemicals but I don't care for the smells of most of these and they are expensive. 

Can anyone help me or give me some new ideas to try?
Thanks for reading! And sorry its so long!
