I used this because even though I don't have dandruff, and have normal hair I get a chronically itchy scalp after washing.
It contains neem oil and oats among other things, and doesn't have an overpowering smell. It's not the best smell but it's not unpleasant.
It doesn't lather as well as supermarket bought shampoos, but still enough to make me feel my hair was clean.
It doesn't leave my hair smelling funny and after brushing when dry, it doesn't go as boof as supermarket shampoos are loath to do - I have fine hair, and a lot of it. My scalp itchiness is calmed a lot too.
It lasts longer than normal bottled shampoo, about 3 months or so, which is great. Price is comparable to what you'd pay for a 'nice' supermarket brand.
