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.

While most people focus on protecting their face, the scalp is often one of the most overlooked areas when it comes to sun protection. This is especially important for individuals with thinning hair, widening part lines, postpartum shedding, or age-related reductions in density, where more scalp becomes exposed to direct sunlight.

A sunburn on the scalp can be uncomfortable, but many people wonder whether it can actually damage hair follicles.

The answer depends largely on the severity and frequency of the sun exposure.

Many people remember to apply sunscreen to their face but forget one of the most commonly burned areas of the body: the scalp.

The scalp is particularly vulnerable because it is often exposed for hours at a time, especially along the part line, crown, and hairline.

While occasional sun exposure is unlikely to cause significant damage, chronic UV exposure can contribute to scalp inflammation, oxidative stress, accelerated skin aging, and damage to the hair shaft itself.

If you’ve been experiencing hair shedding or thinning and your lab results came back “normal,” ferritin may be the missing piece.

Ferritin is one of the most important markers for hair growth, yet it is often misunderstood. Many patients are told their iron levels are fine—even while their hair continues to shed.

Iron deficiency is one of the most common—and overlooked—causes of hair loss, particularly in women.

While many people associate iron deficiency with fatigue or anemia, it can also have a significant impact on the hair growth cycle.

Even without full-blown anemia, low iron stores can disrupt hair growth and trigger excessive shedding.

If your hair has stopped shedding but still isn’t growing back the way you expected, ferritin levels may still be too low.

Hair regrowth doesn’t just depend on stopping shedding—it requires optimal conditions for follicles to re-enter the growth phase.

Diet plays a critical role in maintaining ferritin levels and supporting hair growth.

If iron intake is insufficient, ferritin levels will decline—impacting the hair growth cycle. Here are the best foods for increasing iron.

Hair loss is often attributed to stress, hormones, or genetics—but one of the most overlooked and common causes is low ferritin levels.

Ferritin is a protein that stores iron in the body. While standard lab ranges may consider ferritin levels as low as 10–20 “normal,” optimal levels for hair growth are significantly higher.
