Why Does Crown Hair Loss Occur? Causes, How It Progresses, Nutrition, and Diet

Seeing your scalp show through at the crown in a photo can make you worry about hair loss.

At the crown, the natural hair whorl causes strands to part in different directions. Lighting and wet hair can also make the scalp more visible. Instead of judging from a single photo, compare photos taken under the same lighting and from the same angle to see whether the hair is becoming finer or the visible area of scalp is expanding.

“Crown hair loss” describes thinning at the top of the head rather than a specific medical condition.

Common causes include male and female pattern hair loss. In men, thinning around the crown may occur alongside a receding hairline. In women, a widening central part and more widespread thinning across the top of the head are common. Male Pattern Hair Loss, Female Pattern Hair Loss

Male pattern hair loss involves a genetic predisposition and the sensitivity of hair follicles to hormones called androgens.

Hair follicles are structures within the skin that produce hair. When the enzyme 5-alpha reductase converts testosterone into dihydrotestosterone, or DHT, follicles sensitive to DHT gradually shrink, and the hair’s growth phase becomes shorter.

As this process repeats, newly growing hairs become finer and shorter than before. This is called follicular miniaturization. As the number of thick hairs decreases, the scalp at the crown becomes more visible.

This can happen even when blood levels of male hormones are not elevated. Female pattern hair loss also involves follicular miniaturization, but hormone levels are often normal, and its underlying mechanisms are not exactly the same as those of male pattern hair loss.

Not all thinning at the crown is hereditary.

After childbirth, a high fever, surgery, or rapid weight loss, telogen effluvium may develop, causing increased shedding across the scalp and making the crown look thinner.

Sudden round patches of hair loss should be assessed for alopecia areata. Redness, scaling, or pain accompanied by smooth, scar-like changes in the skin should be assessed for scarring alopecia. Some forms of scarring alopecia begin at the crown and spread outward.

The foundation of nutritional care is eating enough food and including a variety of foods.

Insufficient calories and protein can contribute to additional hair loss, so it is best to avoid overly restrictive dieting and frequently skipping meals. Rotating foods such as eggs, fish, lean meat, tofu, beans, and milk into your meals makes it easier to get protein consistently.

Rather than focusing on a single food or supplement, first look at the overall balance of your diet.

Lean meat, shellfish, beans, lentils, and spinach can help provide iron. Iron from plant foods is less readily absorbed, so pairing these foods with sources of vitamin C, such as bell peppers, broccoli, and mandarins, can help.

Zinc can be obtained from beef, seafood, dairy products, beans, and nuts. These foods are useful for preventing nutritional deficiencies, but they do not directly treat crown hair loss. NIH Information on Iron, NIH Information on Zinc

A sample daily meal plan could include multigrain rice or whole-wheat bread, cooked eggs, milk or unsweetened yogurt, and fruit for breakfast.

For lunch, you could have multigrain rice with lean meat or tofu, accompanied by broccoli and bell peppers.

For dinner, try rice, grilled fish, a bean side dish, and seasoned vegetables. If you need a snack, choose a small portion of unsalted nuts or some fruit. Adjust portion sizes to your age, activity level, and health needs.

Black soybeans and black sesame seeds can also be included in your diet. However, their dark color does not mean they have been proven to thicken hair or restore hair at the crown.

There is also insufficient evidence that biotin supplements improve hair loss in people who are not deficient in biotin. Iron and zinc supplements should be selected based on dietary intake and the results of any necessary tests.

The appropriate approach to crown hair loss depends on its cause.

If your hair continues to become finer or shedding suddenly increases, see a dermatologist for an assessment. Combine dietary changes that address nutritional deficiencies with treatment suited to the underlying cause. It is important not to delay diagnosis while waiting for food alone to restore your hair.
