Lo so boldi ma se navighi un po trovi anche altri studi che affermano l'importanza dello shampoo al Ketoconazolo nella lotta all'aga..
Un po tutti parlano di una modesta ricrescita appunto e non di miracoli(a meno che, come i 3 tester giapponesi qui elencati, non si sia proprio fortunati). Cmq voglio farvi presente una cosa:stiamo parlando di uno shampoo non di una lozione come il minox che bisogna applicare tutti i santi giorni e che non tutti hanno voglia di fare!I capelli bisogna cmq lavarli e farlo con uno shampoo al ketoconazolo fa la differenza!E di molto oserei dire!
L'aga è una 'malattia'(brutta parola lo so) che con il passare del tempo si porta via più o meno velocemente i vostri capelli!Quindi con il passare del tempo ne avrete sempre meno.
Dai vari studi comparativi che ci sono in giro con lo shampoo al Keto si evince che non solo si mantiene ma addirittura si può sperare in un seppur leggero aumento della densità e della consistenza dei capelli!
Poi come dice Gigli ogni aga ha la sua storia e quindi non è detto che funzioni per tutti.
Ma chi ne ha tratto dei vantaggi non dovrebbe mollare questo shampoo.
Chi non l'ha mai provato dovrebbe farlo per un periodo di almeno 6 mesi per trarne le dovute conclusioni. E non mi stancherò mai di dirlo: è uno shampoo!!Se fino ad ora lo avete considerato un semplice prodotto per lavarvi i capelli riconsideratelo che potrebbe essere una buona mossa!
Ne posto un po ma se guardate in internet penso sia possibile trovarne anche altri.
Studio del '98 che dimostra l'importanza dello shampoo contenente ketoconazolo (KZC) al 2%, i cui risultati nel contrastare l'aga, sono stati praticamente paritari a quelli del minoxidil al 2%

Ketoconazole shampoo: effect of long-term use in androgenic alopecia.
[Clinical Trial, Controlled Clinical Trial, Journal Article]
Dermatology 1998; 196(4) :474-7.
BACKGROUND: The pathogenesis of androgenic alopecia is not fully understood. A microbial-driven inflammatory reaction abutting on the hair follicles might participate in the hair status anomaly.
OBJECTIVE: The aim of our study was to determine if ketoconazole (KCZ) which is active against the scalp microflora and shows some intrinsic anti-inflammatory activity might improve alopecia.
METHOD: The effect of 2% KCZ shampoo was compared to that of an unmedicated shampoo used in combination with or without 2% minoxidil therapy.
RESULTS: Hair density and size and proportion of anagen follicles were improved almost similarly by both KCZ and minoxidil regimens. The sebum casual level appeared to be decreased by KCZ.
CONCLUSION: Comparative data suggest that there may be a significant action of KCZ upon the course of androgenic alopecia and that Malassezia spp. may play a role in the inflammatory reaction. The clinical significance of the results awaits further controlled study in a larger group of subjects.
Risultati: La densita dei capelli e la loro dimensione in proprzione al numero di follicoli in anagen è stata riscontrata quasi similare in entrambi i regimi, cioè con ketoconazolo e con minoxidil. Il livello sebaceo è diminuito mediante KCZ mentre è aumentato con il minoxidil.
Un altro studio riguardante il ketoconazolo, presentato al Meeting di dermatologia di Washington del 2001, che conferma la sua utilità come coadiuvante in una terapia contro l'aga.
Inoltre nella riecrca sottostante sono confrontati i benefici apportati dal ketoconazolo rispetto allo zinco piritione.
Nizoral 1% Study Shows Benefits for Androgenetic Alopecia
March 04, 2001
- American Academy of Dermatology Meeting - Washington DC -
Scientists working for McNeil, makers of Nizoral anti-dandruff shampoo, presented the findings of a study done on 1% Nizoral shampoo which has good news for hair loss sufferers. It has long been known that 2% prescription Nizoral has beneficial effects on Androgenic Alopecia (MPB). It however has been unclear whether the same benefits can be obtained by using the non-prescription 1% version.
In the study presented (see below), one hundred male volunteers with mild to moderate dandruff and somewhat oily scalp, were using, in a double-blind fashion, either a 1% Nizoral shampoo or a 1% zinc pyrithione shampoo, 2-3 times a week for 6 months.
Analysis of the different parameters set up in the study shows that the hair diameter gradually increased with Nizoral use (+8.46%) over a 6 month period, whereas the diameter showed a trend to decrease with zinc pyrithione use over the same period (-2.28%). The sebum excretion rate was reduced with Nizoral (-6.54%) while it increased with zinc pyrithione (+8.2%) over the same period of time. The number of hair shed over a 24-hour period was reduced by 16.46% with Nizoral and 6.02% with zinc pyrithione after 6 months. Finally, the percentage hairs in anagen phase increased by 6.4% and 8.4% respectively during the study time.
The results are similar to a previous study done on 2% prescription strength Nizoral where it was shown that use of 2% Nizoral yielded a 7% average increase in hair shaft diameter similar to what was achieved by the control group using 2% Minoxidil and a non-medicated shampoo.
So for any hair loss sufferer, this research clearly indicates that using 1% or 2% Nizoral 2-3 times per week, will have positive effects on hair growth as well as controlling dandruff. It is still unclear at this time whether it's the anti-fungal properties or the anti-androgenic properties of Ketokonazole (active ingredient in Nizoral) thats responsible for the hair thickening effects, however because of the decrease in sebum rates as well, it is the authors opinion that the results are due to the anti-androgenic properties of Ketokonazole.
Nizoral 1% Study
The effects of chronic use of 1% ketoconazole or a 1% zinc pyrithione shampoo on the general health of hair and scalp.
Hundred male volunteers with mild to moderate dandruff and somewhat oily scalp, have used, in a double-blind fashion, a 1% ketoconazole shampoo or a 1% zinc pyrithione shampoo. The test shampoos were applied 2 to 3 times weekly for a total period of 6 months. Several parameters that affect the general health of hair and scalp were assessed at start, and after 1, 3 and 6 months. These parameters included the percent of hairs in anagen phase, the diameter of the hairs, sebum excretion rate at the hairline, and the number of hairs shed in the 24-hour period prior to each assessment. At the end of the study, the participants were asked to complete a questionnaire regarding the cosmetic acceptability of the test shampoos.
Forty-four ketoconazole users and forty-three zinc pyrithione users completed the 6 month study period. Analysis of the different parameters shows that the hair diameter gradually increases with chronic ketoconazole use (+8.46%) over a 6 month period, whereas the diameter shows a trend to decrease with zinc pyrithione use over the same period (-2.28%). The sebum excretion rate is reduced with ketoconazole (-6.54%) while it increases with zinc pyrithione (+8.2%) over the same period of time. The number of hair shed over a 24-hour period is reduced by 16.46% with ketoconazole and 6.02% with zinc pyrithione after 6 months. Finally, the percentage hairs in anagen phase increased by 6.4% and 8.4% respectively during the study time. Except for the percentage of hairs in anagen, which showed no difference between the two groups, all other parameters were significantly different in favor of the ketoconazole shampoo.
Both shampoos have been shown to be good anti-dandruff ingredients. Assessment of parameters than can affect the health of hair and scalp, suggests that both ingredients show distinct differences in the way they affect the scalp; indicating that ketoconazole increases hair diameter and reduces scalp oil, whereas zinc pyrithione seems to yield opposite effects.
