I have a coarse, curly auburn frizz fest nesting above my face. I have a hard time finding styling products which address my many issues, without either neglecting one or causing another. In this case, the benefits so very much outweigh any wee bit of negative, I rejoice in using it.
One great thing is that, on wet hair, it calms frizz and helps keep curl. I slap in about two quarter-sized dollops on my hair (just above shoulders) and let it air-dry. My curls, with little to no other manipulation or product, are tamed and smell nice and not frizzy and are quite shiny. But it takes much longer to air-dry the usual, so I can't quite wash and go.
This is not so good on dry hair, at least not on my dry hair.
The pot does last quite a while, which is good - no?
I am not crazy about silicones in my hair, which kinda build-up, though make my hair look lovely for a while. This product does have some, which is one reason why I left off one star. Another is that it is not great on the second day. Not terrible, but not great. And since, as I said, it is not fantastic on my dry hair, reapply doesn't do any good.
