Pros: This stuff WORKS. It cleans your hair without stripping away its natural softness and curl. Seriously, you won't be able to stop touching your hair the first few days.
Cons: It really does smell weird. Not particularly strong, not particularly terrible, but weird. It also take a decent amount of shampoo to get through all your hair, so it's pretty pricey. Also, if you have any hair that regularly touches your face (bangs, shorter pieces along your cheeks), they will likely look a little greasy by day two.
What I do: I slather this stuff onto my roots and then comb it through my hair. That is the best way to distribute the non-lathering product. I also wash my bangs in regular shampoo to keep them from getting a greasy buildup. The slight alteration to my routine is worth it!
