I'm going to preface this by saying that I haven't had enough time to really see a change in my hair from this product, as I've only had it for 3 days.
The texture of this shampoo is really thick and lovely, and lathers really nicely in my hair. It rinses out very easily too, and my hair feels clean without being dehydrated afterwards. I have coloured hair (bright pink) and my main problem with anti-dandruff products is that they strip hair dye really badly. I found that this shampoo didn't strip my hair colour as much as other Head and Shoulders products have in the past, which is great and might lead me to switch over to using anti-dandruff products more frequently in the future. The scent isn't overpowering which is nice as I've found previous Head and Shoulders products to have a distinct strong smell which I associate with anti-dandruff products. I haven't really noticed any particular anti-dandruff effects but that's likely due to me washing my hair more frequently than usual for this review - my dandruff starts building up after a couple of days post-washing, and I had to wash my hair daily in order to review it, so I can't comment on that.
I'm not new to Head and Shoulders Shampoo but I normally choose the Smooth and Silky version. The shampoo is nice and thick with a slightly blue hue and a clean yet non descript fragrance (I couldn't pinpoint a particular top note but it's lovely and fresh). This is a great choice for men as it's not heavily scented but I was happy using it too. This shampoo arrived just as my scalp was beginning to feel a bit bumpy and itchy (normally a prelude to a dandruff outbreak). After the first use that inflammation had subsided and there was no visible dandruff. The bottle has the normal packaging with the blue and white and is easily recognisable. I normally use head and shoulders for a week or so when my dandruff flares before returning to my standard shampoo (one for lasting colour). But a bottle would last me about 2 weeks with continuous use. On ocassion I have used head and shoulders for more than three months and it always leaves my hair shiny and silky and my scalp flake free. I'd totally recommend this to anyone suffering from dandruff.
Tips: I have never repeated application of the shampoo in the same wash but I do tend to leave it on for at least two minutes before washing out.
