Hair care

At Zurko Research we have always welcomed collaborations aimed at expanding the range of services we offer, as well as improving their quality.

In the area of hair care, we collaborate with expert institutes; which allows us to offer our clients a full range of tests related to hair and scalp. We carry out studies for hair loss, seborrhea, conditioning / styling and colouring products, or pediculosis, among others.

Moreover, thanks to these collaborations, we have been able to extend our volunteer data base up to 4,000 participants with specific characteristics for each type of test.

We make a difference by designing studies to meet our clients’ needs, in compliance with high quality standards and in accordance with the principles of Good Clinical Practice (GCP) and Good Laboratory Practice (GLP).
