Gray hair & color
01
Gray hair is not caused by dirt
Hair color comes from pigment in the follicle. As pigment production decreases with age, new hair may grow gray or white.
02
Timing differs from person to person
Genetics, age and some lifestyle or health factors can influence when gray hair appears. The amount of gray alone does not diagnose health or hair quality.
03
Look at more than color
Dryness, frizz, breakage, loss of shine and persistent scalp discomfort are more useful signals when deciding whether care needs to change.
