The death of the melanocyte (pigment) stem cells causes hair to begin turning grey.
A grey head of hair is in fact the result of the contrast between the dark and white (colorless) hair forming an overall 'grey' appearance to the observer. If you’re grey with a stiff scalp, Serum 4 (CHILL AFTER SUN) is recommended; if you’re grey with a dry scalp, Serum 5 (TRIUMPHANT FOR MEN) is recommended; and if you’re grey with thinning hair, Serum 6 (BOOSTER FOR MEN) is recommended.

5. What Serum do you recommend for African American Hair?
Choose a Serum that speaks to the condition of the scalp and hair, not the color. African-American hair has a darker, stronger pigment, which has a tendency to be curly and dry. Furthermore, African-American hair tends to be subjected to a fair amount of processing at the salon. For super results, start with Serum 7 (SPARK YOUR YOUTH) and continue with Serum 4 (CHILL AFTER SUN).

6. Can both natural and processed blondes use the same formula?
Some facts about blondes: Blondness is found in a little less than 1.8% of the world's population. Blondes have an average of 140,000 hairs. Natural blondes have the thinnest strands of hair. Whether natural or processed, a blonde’s yellowish color is caused by a patchy, scarce distribution of pigment. Both types of blonde have very sensitive hair due to genetics or color processing -- and therefore can use the same formula.

7. How is SERUM 7: SPARK YOUR YOUTH different from the other formulas?

14. How often should I use YAROK?
If your scalp or hair is in crisis (for example, dry, itchy, flaky or just plain lackluster), twice a week for an entire month is recommended followed by once a week for maintenance on-going.

15. Is YAROK 100% organic?
To be certified organic, a product needs to contain 94% organic ingredients. However, it's challenging to ensure that all YAROK formulations are 94% organic due to the rarity of the ingredients chosen coupled with the differing climates and organic guidelines in each country. YAROK promises formulations that are more than 78% organic along with non-sprayed, responsibly harvested ingredients. The sources for our essential oils where chosen for their traceable records (each has a certificate of origin for their plant sources) and a passion for the practice of Aromatherapy.

16. Is the packaging recycled or recyclable?
YAROK packaging is recyclable.

17. What happens if the Serum gets in my eyes?
Rinse your eye with warm water and repeat until flushed. If a burning sensation continues, seek medical attention.
