My hair is so dry and brittle. please help.?

It's so dry and weak/brittle that when i brush or comb it it just breaks off. Its not even like a whole strand of hair falls out, it's these like 3-5 inch pieces, and i have really long straight hair.

omg it sucks so bad. i don't know why it is like this. I blow dry it only three times a week at most, and smooth it with the straightener maybe twice.

What products can fix this and keep it soft, silky, and shiny?

i would recomend, for a short time, to stop all heat styling for like a week and use a shampoo and conditioner that specializes in mostiure or damage defense (pantene daily hydration line works great, so does tresemme damage defense is really good too.) And get a deeeeeep conditioner (aussie three minute leave in works nicely). And after you see improvement in your hair, then maybe start to blow dry and i suggest to do one or the other with the blow drying and hair straightener becasue that will make more damage if you do both. and to keep your hair smooth use john frieda frizz ease serum. :)
