Dandruff vs. Something More Serious
Gàu da đầu: nguyên nhân, triệu chứng và cách điều trị hiệu quả
Doctors emphasize that most dandruff is harmless. The concern is not flakes alone, but flakes that behave differently.
Typical dandruff:
Comes and goes
Responds to treatment
Does not cause pain or bleeding
Concerning scalp changes:
Persist despite treatment
Become thicker or crusted
Bleed or form sores
Change in size, color, or texture
If symptoms fall into the second category, medical evaluation is essential.
Who Is at Higher Risk?
Certain groups face a higher risk of scalp skin cancer, including:
People with prolonged sun exposure
Individuals with fair skin
Older adults
People with thinning hair or baldness
Those with a history of skin cancer
However, doctors caution that no one is immune.
