How can I spot exaggerated claims about gray hair care?
Three judgment criteria: Whether the efficacy boundary is clearly explained - gray hair care is scalp health management, and it does not promise that gray hair will turn black (PMID 32654282); if the words "guaranteed", "white hair turns black" and "radical cure" appear in the promotion, it is an exaggeration; whether it is recommended to seek medical treatment when necessary to investigate reversible causes (PMID 30607038).
Suggested approach: Go to the location and ask directly about the efficacy limits to see if the answer is honest; personal descriptions of the effects online are unverified information and are for reference only; gray hair issues should be evaluated by a dermatologist before arranging maintenance.
