The scents are not the same, and they are ok, but not vanilla or anything. They are just ok, can't describe. The bottles are labled : dry hair, dry scalp, color treated, normal, and I think there may be another. I use a combo of dry hair, and color treated (half and half) and it seems to work. My hair smells nice, but the best way to describe it is "herbal" - I love almond scent, wish they had that like Wen does. But I can get purfume .....
Also, you can get a small packet for like $2 each to try them, and get a few to see which works for you. You can get it on Sally's website too. Might as well give it a try, especialy if you're on a budget.
Hope that helps - Jo
