Upon seeing the presentation of the vials, me, the wife, thought 'wow isn't that fancy!'. The husband's reaction was 'that's a bit much'.
They come in a beautiful presentation box - with detailed instructions of how to use, but minimal information on what to expect.
My husband used this religiously, thanks to my nagging him, but I think he's in the routine now and would continue to use them without reminders.
The vial is easy to use, and the recommended 8 drops was enough for his scalp. He said unlike the shampoo he felt no tingling at all from this.
Thankfully it didn't leave his hair greasy, and seemed to be absorbed easily into his scalp.
Used with the shampoo, my husband has noticed great improvement in hair fall (as in...his hair is staying put) and is excited that his hair feels and looks thicker. He'll continue using it and has asked me to repurchase the essence (the shampoo will last a lot longer) so I guess it's worth the effort of daily use!
