FAQ - Frequently asked questions

DuoLife Keratin Hair Complex

What is the origin of keratin found in the composition of Keratin Hair Complex dietary supplement?

The solubilised keratin used in Kertain Hair Complex was obtained in a patented process of controlled hydrolysis of wool from New Zealand sheep, maintaining its original amino acid profile.

Is Keratin Hair Complex dietary supplement suitable for vegans?

As the product contains solubilised kertain obtained from sheep wool, Keratin Hair Complex is not a vegan preparation.

Can Keratin Hair Complex be used in children?

Keratin Hair Complex dietary supplement is suitable for children over 12 years of age.

Can Keratin Hair Complex dietary supplement be used by pregnant and breastfeeding women?

In case of pregnant and breastfeeding women, an attending physician decides about any supplementation. A woman's body during this period has specific needs; therefore individual approach and consulting your attending physician is key. Checking and defining the body's needs is necessary. Basing on interview and test results, the attending physician is able to determine which nutrients - and at what doses - are needed by a given person.

Is this product backed by clinical trials? 

Clinical trials are linked with numerous raw ingredients used in the composition of our products, not the products themselves.

Organic pea shoots found in DuoLife's Keratin Hair Complex was subject to clinical trials conducted by the Manufacturer on a group of 21 volunteers with mild to moderate hair loss. The extract was taken by mouth, at a dose of 100 mg per day, for two months. Hair loss was measured three times: on the first day of the trial, after a month and after two months of using the extract. There was a statistically significant hair loss decrease by 34% after one month of using the product, and by 37% following 2 months of use. A visible improvement in hair thickness was also noted. At the same time, we would like to highlight that daily dose of organic pea shoot extract used in the above-mentioned research equalled 100 mg and is identical with the dose found in recommended daily portion (50 ml) of DuoLife Keratin Hair Complex dietary supplement.
