Had a long struggle with dandruff and itchy scalp, tried by the branded goods to all of bioproducts. Only recently (Crisan had for years successfully in use) I tried again eimal an organic product and that an anti-dandruff Soap (Amazon ordered). Immediately after the first application I had an itchy scalp and the hair was like straw. On the second day already kindled the scalp like fire and I had to resume the application with Crisan. Immediately after shampooing the itching ceased and the hair was smooth again.
In my review after I could think would it get from Crisan money but after several attempts with other branded products and Bioartikeln I am instructed Crisan (Crisan Junky) and do not want to miss it.
It would be interesting even if there is an expiration date for such care products or I would stockpile for the next 20 years.
