Prep is more suitable as a primer for your styling routine. While it is still soft on the hair, it doesn't have as much soothing power as the tonic does. Prep has a bit more styling power. Having said that, now that I have used both extensively, I love that Tonic soothes my itchy scalp and I love layering it under my other products. Hope that helps!

I'd try a small bottle of each and see which one you like best. I love the tonic and the way it makes my scalp feel.

I have fine wavy hair and I use tonic for my itchy scalp, and it really soothes it! I think it's because it contains tea tree oil, whereas prep does not. I use it to refresh my scalp and hair after the second day and before I work out. My hair never tangles, so I can't comment on that. However, I spray twice on each section and it never makes my hair greasy. it also miraculously tames my boyfriend's curls. I don't like the tea tree smell, but other than that, I'd go for this one. Prep has less/no mintyness based on ingredients.

I have fine hair that is color treated I use the tonic and I love it. I use it daily whether my hair is wet or dry. It protects the scalp and nourishes my hair. I do not blow dry my hair - ever. It takes too much time.

Go for the BB Prep 100%! I just tried using the Tonic for it's benefits; but it isn't worth it and left me with tangles. Prep made my hair softer and didn't weigh it down.

I've used both, and totally prefer Prep over Tonic. I also have dry hair (although incredibly thick, not thin), and feel that Prep is more nourishing. Aside from helping with dryness, it also seems to work better with my hair texture--light, without weighing it down (I've come to embrace my big hair!), and helping tame the fly-aways/static whether I air dry or blow dry. Tonic was just a bit too heavy for me, and once I switched to Prep, there was a noticeable difference in management, feel, and dryness. Regardless, everyone's hair is different, so you might want to consider buying the travel sized bottles of each and trying them out separately for a week or two before making a final decision.
