Last advice - back to the old ways and that includes, among others, the All Soft Heavy Cream - now in the new presentation with IPN (Interlock Protein Network). Can therefore penetrate deep into the hair oo ultimately. Whether this is sustainable better than its predecessor I can not judge. The main thing it works just as lasting as the first. If the consistency minimal different. Every one or two weeks more leave for about 10 to 15 minutes, lather, rinse and and everything will be fine), really true.
Überpflegt is in such an application also nothing, because I use it only towards us again. After washing with the extreme series. For me and my long wavy hair still the best.
Conclusion: Out for experiments with brittle and dry hair. Can only be recommended.
PS: a price comparison on the net worth.
PPS: I am looking forward to the next visit to the hairdresser, and a silicone-containing chemical hair color :)!
