Frontal Fibrosing Alopecia and Sunscreen: What the Research Actually Shows
By Board-Certified Trichologist Shab Caspara
Frontal fibrosing alopecia (FFA) is a form of scarring hair loss that primarily affects the frontal hairline and eyebrows.
Over the past decade, researchers have explored whether certain environmental exposures, including sunscreens, may play a role in the condition.

Why Sunscreen Entered the Conversation
Researchers observed that some patients with FFA reported frequent sunscreen use.
This prompted investigations into whether ingredients commonly found in facial products and sunscreens might contribute to the condition.
What About Titanium Dioxide?
Titanium dioxide is a mineral UV filter widely used in sunscreen formulations.
Some studies have identified titanium dioxide particles around hair follicles in biopsy samples from individuals with FFA.
This finding led researchers to investigate a possible association.
What the Research Does Not Show
Current evidence does not establish that sunscreen causes FFA.
The studies available have several limitations, including:
small sample sizes
observational designs
inability to prove cause and effect
At present, the relationship remains an association rather than a proven causal link.
What Should Patients With FFA Do?
Individuals with FFA should continue practicing sun protection.
Options may include:
hats
UPF-rated clothing
alternative sunscreen formulations
