6 Anti-Aging Benefits of Black Sesame Seeds for Darker, Thicker Hair

If you’re aiming for darker, thicker hair as you age, black sesame seeds might be your quiet powerhouse. You’ll get nutrients like biotin and essential fats that support keratin, plus antioxidants that fight oxidative stress. There’s also sesamin, which may help curb DHT and reduce shedding. Used right, they can support melanin for richer pigmentation and stronger strands. But timing, form, and who should skip them matter—here’s how to get it right.

How to Use Black Sesame: Forms, Dosage, and Timelines

Whether you prefer topical care or edible options, you can use black sesame in several practical forms with simple timelines.

For a ready-made approach, shampoo first, then apply a 300 ml topical formula to your ends, massage evenly, leave 5–10 minutes, optionally steam 10–15 minutes, and rinse. International deliveries are estimated at 7–28 days depending on your location.

For DIY, mix ground black sesame with yogurt, or massage black sesame oil into the scalp as needed.

For edible use, snack on one tablespoon of seeds daily.

For soups, toast whole seeds until fragrant, cool, then blend with soaked sticky rice and water; strain, cook on low with sugar until thickened. A single batch can use 50 g seeds and 60 g rice.

Expect softer, silkier hair after the first topical use; track dietary progress over months.

How Black Sesame Supports Thicker Hair Growth

Thicker hair starts at the follicle, and black sesame seeds feed it with the right mix of nutrients and protective compounds. You get biotin to drive keratin production, iron to deliver oxygen for ideal growth, and vitamin E to shield follicles from oxidative stress. As part of Avimee Herbal’s approach, we combine Ayurveda with modern science to ensure high-quality ingredients that support consistent hair results. Additionally, the antioxidant properties of black sesame seeds help combat oxidative stress, which can impair hair growth.

Thicker hair begins at the follicle—black sesame seeds nourish with biotin, iron, and vitamin E.

Copper and zinc support melanin and follicle integrity, while essential fatty acids hydrate strands and keep the scalp supple.

Nourish your scalp further with sesamin, sesamolin, and lignans that calm inflammation, reduce swelling, and improve nutrient delivery. Vitamin B1 supports cellular energy, helping follicles stay active.

Massaging black sesame oil boosts circulation, enhancing oxygenation and nutrient transport to roots.

Plant proteins reinforce strand structure, fatty acids increase elasticity, and minerals fortify roots—reducing breakage. Antioxidants preserve thickness by limiting damage and supporting a steady growth cycle.

How Sesamin in Black Sesame Helps Block DHT

Beyond feeding follicles for fuller strands, black sesame brings a targeted edge against DHT through sesamin, its primary lignan. Identified as sesame’s key compound, sesamin stabilizes the oil and delivers potent biochemical activity. You benefit because sesamin inhibits 5α-reductase—the enzyme that converts testosterone to DHT—thereby easing androgen-related hair loss.

In cell studies (DU-145), sesamin reduced type-1 5α-reductase and blocked DHT synthesis. At 0.1 mg/ml, it inhibited 37.38±4.26% of control activity, outperforming finasteride by 1.54×, though trailing dutasteride by 1.27×.

A 2015 study confirmed this superior enzyme blocking versus finasteride, while Keimyung University data showed sesame oil phytosterols cut hepatic 5α-reductase by up to 44%.

These in vitro results, alongside a CC50 of 1.83±0.90 mg/ml, support safe oral intake to reduce systemic DHT, slow miniaturization, and promote thicker hair. Additionally, sesame oil is rich in antioxidants, which can help protect hair and scalp health while supporting its traditional use in Eastern medicine.

Black Sesame and Hair Pigmentation: Delaying Greying

Although greying is a natural part of aging, black sesame may help you hold onto your hair’s color longer by supporting melanin production and shielding pigment cells from stress.

You benefit from sesamin and related compounds that induce melanin content and boost tyrosinase activity—the enzyme that kickstarts pigment synthesis. Animal and cell studies show black sesame extracts increase melanocyte activity and gradually restore natural color, with a 2019 study reporting delayed greying. Additionally, the anti-inflammatory properties of black sesame may further enhance scalp health, contributing to better overall hair vitality.

You also get nutrient support for pigment maintenance. Black sesame provides copper, iron, zinc, and B vitamins that nourish melanocytes; copper, in particular, stimulates tyrosinase and helps retain natural tone. These nutrients, alongside vitamin E, help neutralize oxidative stress that can damage pigment cells.

Its seed coat contains heat‑stable edible melanins and phenolic precursors—like caffeic and ferulic acids—plus darker‑seed flavonoids that act as co‑pigments, reinforcing hair pigmentation.

Antioxidants and Minerals in Black Sesame for Hair Health

While hair health hinges on more than one nutrient, black sesame seeds deliver a compact mix of antioxidants, biotin, iron, essential fatty acids, and trace minerals that directly support your scalp and strands.

Their antioxidants—especially sesamin and sesamolin—neutralize free radicals, shield follicles, and reduce oxidative stress that drives shedding. You get steady biotin to fortify keratin, enhance protein and fat metabolism, and sustain follicle activity for thicker-looking hair. Additionally, incorporating papaya’s enzymes can further enhance nutrient absorption for optimal hair health.

Iron in black sesame improves oxygen delivery to roots, helping prevent anemia-related thinning and promoting denser growth.

Essential fatty acids hydrate the scalp, reinforce the barrier, boost elasticity, and strengthen cuticles to curb breakage. These seeds are also rich in calcium and magnesium, supporting bone health that indirectly underpins robust hair growth.

Minerals like zinc, magnesium, copper, calcium, and selenium bolster collagen, stabilize structural proteins, anchor roots, and amplify antioxidant defenses for resilient, nourished hair.

Who Should Skip Black Sesame: and How to Get Better Results

Even natural remedies have limits, and black sesame isn’t right for everyone. If you’ve ever reacted to sesame, skip it entirely—oral or topical exposure can trigger hives, nausea, breathing trouble, or a dangerous drop in pulse. Seek urgent care for severe symptoms, and patch test first if your scalp is sensitive.

If you’re pregnant or breast-feeding, stick to food amounts only and talk to your doctor before any medicinal use. Avoid black sesame beyond culinary levels if you take tamoxifen or P‑glycoprotein substrate drugs; interactions can alter efficacy and side effects. Consult your physician if you have low blood pressure. Regular scalp massage with sesame oil may soothe irritation and support scalp health, which can help reduce flaking and discomfort.

For better results, use moderate portions, grind seeds for absorption, and watch blood glucose.

For topical use, limit contact time and shampoo thoroughly to prevent clogged follicles.

Frequently Asked Questions

Can Black Sesame Interact With Common Hair Supplements or Medications?
