Right out of NY

I'd really like to try something new and good for my hair. I've heard Redken is great. I wouldn't know, never tried it. Anyone who did? What was it like? Better than the regular products you can get at any grocery store? The problem is they're like 10 times the price of what I normally use. These are the ones I'd like to try out: Body Full / Blonde Glam / Expert
