Q96
What can and cannot be achieved with gray hair care?
What it can do: Scalp health management - clean and maintain the condition of the scalp; when immediate coverage is needed, it can be used with hair dyeing plans. What it cannot do: turn gray hair black again. This is not supported by a recognized treatment (PMID 32654282).
If gray hair suddenly increases or appears at an early age, it is recommended to go to a dermatology department to check for reversible causes (thyroid, vitamin deficiency, etc., PMID 30607038). When you go to the location, you can directly ask "What can and cannot be done with gray hair care?" Organizations with honest answers are more trustworthy.
