The results of independent research confirm the quality and effectiveness of products from the Advanced Formula line!

18.05.2020
Dear Club Members,
DuoLife products are tested at various stages to verify their quality and effectiveness. Recently, we have subjected two of our products –DuoLife Advanced Formula Shampoo and DuoLife Advanced Formula Conditioner – to specialized tests in an independent, renowned laboratory. Now, following the principle of transparency, we would like to share the results with you!
For starters, we'll give you some details about the tests themselves. The laboratory conducted them both in controlled (selected hairdressing salon) and uncontrolled (home panel in a group of volunteers) conditions. This approach has significantly increased the scope of the tests and made them comprehensive, so that the results can be considered reliable.
The age range of the volunteers who tested both products:
23 to 68 years for the hair conditioner;
23 to 71 years for the shampoo;
Age diversity, and thus different hair care needs, are further factors illustrating the complexity and relevance of the research.*
But let’s get to the point. Tests performed in an independent laboratory confirmed that DuoLife Advanced Formula Shampoo and DuoLife Advanced Formula Conditioner products:
intensively care for weak hair prone to falling out,
strengthen hair and improve their condition,
make hair thicker,
improve hair elasticity/flexibility,
moisturise hair/reduce hair dryness,
reduce hair loss,
make hair shiny and sleek,
promote hair smoothness (ends split less often),
do not disturb the natural pH of the skin,
improve the overall appearance and condition of the scalp.
The effectiveness of both cosmetics is also reflected in the detailed opinions of the testers, which the laboratory presented in the charts below.
The effects of regular application of the shampoo, according to the testers:
Shiny and smooth hair
Definitely yes or yes

Hair pleasant to touch, regenerated

To us, the comprehensive test results are clear evidence that Advanced Formula products meet the highest quality standards. The opinions of satisfied users, and above all – DuoLife Club members who are eager to use our shampoo and conditioner – are the best form of appreciation for us.
