This product did nothing to control my frizz.  I live in Florida where the humidity is off the rails and this product was an epic fail for me.  Yes, it doesn't contain silicone, and that's great for those who are silicone sensitive.  However, silicone is the only defrizzer that works for me when the humidity climbs to 90%.  This balm does smell wonderful and goes on smoothly, and it did make my dry, frizz prone hair smooth.  But once I stepped outside my air-conditioned house, all hell broke loose.  Within an hour, the frizz was back with a vengeance and I was right back where I started, as if I had not applied any product or made any effort at styling my hair at all.  So I can't exactly understand the good reviews for this product.  I purchased it at Ulta, so I know it is authentic.  I also purchased Phyto 7 leave in conditioner, which is nice.  However, this product is promptly going back to the store.  Years ago, this was a cult favorite, but that was before silicone serums started appearing on the market.  As far as the Florida humidity goes, only silicone is strong enough to eliminate Florida frizz.  I recommend a few products that have worked well for me.  For drugstore, Got2b Shine Serum is pure silicone and works as well as much more expensive serums.  Moroccan Oil Treatment and Macadamia Professional serum are both good options.  Apply these to clean damp hair.  I use about a nickel size dollop for my below shoulder length hair.  Be careful not to apply these products to the roots.  I apply them to the midlengths and ends and then, without adding any more product, I smooth what's left on my hands over the top layer of my hair, avoiding the part.  Also good, is Bumble and Bumble Invisible Oil Primer, which hydrates, provides thermal protection (as do the serums), adds shine and eliminates frizz completely.  It's a 10 Miracle Leave-In is also good.  Spray these on clean damp hair before styling products.  These products are holy grail products for me and work much better than Phyto.  But if you're on a no silicone kick, by all means give this product a try.  However, if the humidity where you live is high, you'd be better off with one of the serums or sprays I've mentioned.  I definitely don't recommend this product.
