Question about shampoo/conditioner?

I have long hair and it is dry/damaged and brittle and also breakage sometime. I use herbal essence and it didn't work very well. I also use loreal sulfate free but sometime it itches. I want to know if garnier frutics is good to use for long hair or not because I notice some say it not good for hair. Any other product that might help as well? I am go to trim my hair next week.
