Study says leave shampoo in for 5 mins


#1

Now we have proof that it’s beneficial to leave the shampoo in for at least 5 mins rather than rinsing right away.

C. Piérard-Franchimont, E. Uhoda, G. Loussouarn, D. Saint-Léger, G. E. Piérard. Effect of residence time on the efficacy of antidandruff shampoos.

International Journal of Cosmetic Science Volume 25, Issue 6, Page 267-271, Dec 2003

Synopsis

Dandruff is known to be controlled by fungistatic shampoos active against Malassezia spp. These products also remove the loosely attached scales. This study was performed to assess the effect of a 5-min residence time on the efficacy of antidandruff shampoos. Two commercially available shampoos were used in two groups of 21 panelists with severe dandruff. They contained either 1% ketoconazole or 1% piroctone olamine. In each group, intraindividual comparisons were made by a split-scalp design between the effect of a 5-min residence time versus no residence time. Both shampoos induced significant reductions in scaliness and yeast colonization. The beneficial effects were obvious immediately after one single shampooing and 3 days later as well. The improvement was greater with a 5-min residence time. The piroctone olamine treatment benefited more than the ketoconazole treatment from the extension of shampoo-exposure time.

In conclusion, the benefit of a residence time in treating dandruff is documented. The level of improvement in efficacy may vary according to the nature of the shampoo.

Most, if not all, shampoos also direct you to “Lather, Rinse, Repeat”

Why do they tell you to repeat??? So you’ll use twice as much and buy more.

They also don’t tell you that you have a bald future ahead of you. That’s the thanks you get for using their toxic products.

Class dismissed…
