STYLETHREAD -- LET'S TALK SHOP!

i really like amplify by matrix.  they have a root spray, mousse, shampoo and conditioner that all work really well.

also i like to use this spray i get at target by loreal proffessional.  it is a volumizing conditioning spray.  it is $12.99 for a small bottle, but is makes such a huge difference.  you can't even feel it in your hair.  i am not sure where else you can find it. 

kms reconstructing treatment is great for a once a week moisture boost and to help mend dead split ends.  and is smells amazing. 

if your hair is blonde, i would recomend john frieda's dream cream for when your hair is dry and your ends are looking frazzled.  just rub a little into the ends and it is and instant improvement.

i love thermasilk's leave in conditioning spray.  and v05 makes a miracle mist that protects your hair from styling damage and also helps hold your style and i love that as well.

It may be too late if you've already bought some stuff, but I used to have the same problem. I now have a strict hair regimen and it seems to have solved all of my problems. I first shampoo with Biolage Color Care shampoo and follow it with the matching conditioner. When I get out of the shower, I use a spray in heat protector (thermasilk). Then I follow with something I found on amazon, it's called Keratin Hair Coating Essence. It's a serum and it really smooths out the hair. THEN, I use Aveda Hang Straight and blow dry my hair. Next, when I use the flat iron, I spray in Matrix Flat Iron Heat Protector. Then, to give my roots a little lift, I finish with Aveda Sap Moss Styling spray. This stuff is AWESOME, a little bit goes a long way and it really stays.

Also, I would try using a wide tooth comb in the shower when you put your conditioner in. HTH!
