My weekly treatment shampoo, the bundle is better due unless the single one is selling 3 for 2. 

This brand in whole is amazing and this product does work. I highly recommend it.

If does what it says, dandruff has completely disappeared, but my hair does feel heavier after a while of using 

Hasn't helped my greasy hair at all. In fact it's worse. I could go one day without washing my hair just using a bit of dry shampoo but with this shampoo it's greasy by the end of the day! Will not be wasting my money again.

I suffer with patches around my scalp that get itchy and leaves big flakes. This shampoo is great - from first wash my scalp felt clean and less itchy. After three or four washes my flakes cleared up. It makes your hair less greasy which is amazing as it lasts longer between washes. It also leaves your hair incredibly soft! Brilliant shampoo
