Ich habe es früher selbst angewendet. Mittlerweile distanziere ich mich von Ketprodukten, denn ein Shampoo für 5-10 Minuten einwirken zu lassen kann langfristig niemals föderlich für die Kopfhaut sein Es trocknet die Kopfhaut regelrecht aus. Dadurch fetten die Haare auch schneller und genau das führt auch zu Haarausfall und zu einer Beschleunigung der Aga.

Im Link geht es um die orale Einnahme. KET ist toxisch,

dankeschön
das wars ich werde KET nicht erst probieren.

Ich habe KET auch ca. 2 Jahre lang benutzt. War ok.
Nun H&S und ist auch ok.
Also mMn beides ok gegen Schuppen. Ich konnte keinen Unterschied feststellen, zumindest nicht was die Schuppen beseitigung betrifft.

KET trocknet allerdings ziemlich stark die Kopfhaut aus, das macht H&S nicht.
So habe ich das empfunden.

Hair shedding and hair thinning have been reported to be affected by dandruff and seborrhoeic dermatitis. The present study was conducted in 150 men presenting with telogen effluvium related to androgenic alopecia associated with dandruff. They were randomly allocated to three groups receiving each one of the three shampoos in the market containing either 1% ketoconazole (KTZ), 1% piroctone olamine (PTO) or 1% zinc pyrithione (ZPT). Shampoos had to be used 23 times a week for 6 months. Hair shedding during shampoo was evaluated semiquantitatively. Hair density on the vertex was evaluated on photographs using a Dermaphot. Trichograms were used for determining the anagen hair percentage and the mean proximal hair shaft diameter using computerized image analysis. The sebum excretion rate (SER, g cm2 h1) was also measured using a Sebumeter®.
The three treatments cleared pruritus and dandruff rapidly. At end point, hair density was unchanged, although hair shedding was decreased (KTZ: -17.3%, PTO: -16.5%, ZPT: -10.1%) and the anagen hair percentage was increased (KTZ: 4.9%, PTO: 7.9%, ZPT: 6.8%). The effect on the mean hair shaft diameter was contrasted between the three groups of volunteers (KTZ: 5.4%, PTO: 7.7%, ZPT: -2.2%). In conclusion, telogen effluvium was controlled by KTZ, PTO and ZPT shampoos at 1% concentration. In addition, KTZ and PTO increased the mean hair shaft thickness while discretely decreasing the sebum output at the skin surface.

From the full study:

Conclusion

The present study comparing 1% KTZ, 1% PTO and 1% ZPT shampoos has demonstrated that these products have some other benefits in addition to their reported antidandruff effect. The data show that these shampoos have a beneficial effect on the anagen/ telogen ratio, by increasing the anagen hair percentage in subjects with dandruff. This results in a reduced hair shedding. In addition, the data show that 1% KTZ and 1% PTO, but not 1% ZPT, produce a beneficial effect on scalp seborrhoea and hair shaft diameter. The reason for such opposite effect is unknown. Finally, the data show that scalp seborrhoea is inversely correlated with hair thickness. The virtue of such a finding is its simplicity. However, the results cannot be taken at face value. There may remain debate whether reducing sebum excess on the scalp may lead to thicker hair, and whether increasing scalp seborrhoea may be accompanied by a reduction in the hair shaft diameter. </span></span>

Even with all the available data, for some reason retail stores have not caught on to the upcoming demand, and these products can be difficult to find.

"Shampoos had to be used 23 times a week for 6 months"

23 mal pro Woche die Haare waschen? Praktikabel ist das nicht.
