Demi Moore’s shiny and waist-length locks aren’t just beautiful — they reveal a fundamental truth about hair health: It starts from within.
The actress has been in the spotlight for snagging her first major industry award Sunday night at the Golden Globes, and many have been talking about her hair. Experts say her approach to hair care reveals important lessons about maintaining healthy locks at any age.
“When I’m not working, I try to do as little to it as possible. It’s stressful even having someone touch it. If I don’t have anywhere to go, I don’t put heat on it — I just try to let it do its own thing. And I don’t wash it too often,” Moore told People in a 2022 interview. “I get regular tiny trims. The rest comes from the inside out. You have to eat well, all those things.”
Beatriz Robles, a food technologist and expert in nutrition and dietetics, told Vogue, “Changes in the appearance, volume, or density of hair can be a sign that there is a nutritional deficit in our diet.”
The science of healthy hair extends beyond luxury products; it involves nourishing your hair follicles with the right nutrients. Here’s how diet influences hair health, according to Healthline:
The building blocks of healthy hair
Healthy hair starts with your daily diet. Keratin (protein) accounts for about 90% of each hair strand, according to Nexxus, so it’s essential to consume enough protein for proper growth and strength. Essential fatty acids, particularly omega-3s found in fish, nuts and avocados, help retain moisture and maintain scalp health. Additionally, iron deficiency, which is common in women, can lead to hair loss.
Vitamins are essential
Research in the National Library of Medicine demonstrates vitamin deficiencies significantly affect hair health. Vitamin D, present in egg yolks and fatty fish, stimulates new follicle formation. Vitamin E acts as an antioxidant shield against environmental damage, while vitamin A produces sebum, your scalp’s natural moisturizer.
Less is more
Moore’s minimal-styling approach aligns with current research. Excessive use of heat can strip hair’s natural protective barriers.
“When heat is applied, the natural oils are stripped from your hair, and the water molecules evaporate, changing the hair’s protein structure,” research highlighted on Dyson’s website states. “The high temperatures cause the water to dry up quickly, which affects the structure of each strand and can crack the cuticles, the outer layer of hair, making hair more vulnerable to further damage.
You have a winning formula for keeping your locks healthy when you pair proper nutrition with consistent hair care. Embrace these tips, and your hair will thank you.
