I had never used a scalp scaler before but this was great. The tube is very easy to use and it also functions as a shampoo to make things easier. The smell is overwhelming at first but after washing it out it leaves a very fresh scent, almost like fabric softener? It is also the only 'shampoo' I've been able to use that has kept its scent for longer than a day. However, if you have a sensitive scalp the scent may be too much, as it is so strong it makes my eyes squint if that makes sense, but I experienced no irritation or flaking afterwards, and I could go a bit longer between my washes, which was great.
