CrazycatLady, I'm sympathetic to how you are feeling about your hair. I can tell it is really affecting you.

Step 1 - I would check yourself out physically. The whole 9 yards - tests for iron, thyroid function, estrogen levels etc.

Step 2 - How is your diet? Read up on a healthy diet including adequate protein, fats, vites. & minerals and then do your best to follow it.

Step 3 - try the entire CG method starting with a clarifying shampoo.

Step 4 - Get a haircut to cut off the limp, thin ends.

Step 5 - Use lightweight, volumizing products like Deva Volumizing foam.

I'm sure you can improve the situation if you can identify what is causing this drastic change in your hair. Please post back - I'll watch for your posts and I'm sure others are also interested.
