1. Almonds
Almonds are more than a crunchy snack—they’re packed with nutrients that can help your hair thrive. Rich in biotin, vitamin E, and magnesium, almonds support hair follicle health and promote stronger, shinier strands.
"Almonds are packed with biotin, vitamin E and magnesium to strengthen your follicles," Doshi explains. Including a handful of almonds in your breakfast or as a mid-morning snack can give your hair the nutrients it needs to grow resilient and lustrous.
2. Walnuts
If you’re looking to improve scalp health and reduce hair breakage, walnuts should be on your radar. These nuts are high in omega-3 fatty acids and antioxidants, which nourish the scalp and create the ideal environment for hair growth.
"Walnuts are rich in omega-3 fatty acids and antioxidants for your scalp nourishment," Doshi says. Adding a few walnuts to oatmeal, salads, or smoothies can help maintain your scalp’s natural balance while promoting fuller, healthier hair.
3. Brazil Nuts
Brazil nuts are a powerhouse when it comes to promoting strong hair strands. They are exceptionally high in selenium, a mineral essential for the enzymes involved in keratin production—the protein that forms the structural foundation of your hair.
"Brazil nuts are rich in selenium, which aids enzymes involved in keratin production and helps follicles grow strong strands," Doshi notes. Eating just one or two Brazil nuts a day can provide your body with enough selenium to support healthy hair growth without overdoing it.
Bonus Nuts: Cashews and Pistachios
While almonds, walnuts, and Brazil nuts are standouts, other nuts like cashews and pistachios also contribute to hair health. They are rich in iron, zinc, and biotin, which are key nutrients for maintaining hair fullness and shine.
Cashew and pistachio are rich in iron, zinc and biotin for that fullness and shine. Incorporating a small mix of these nuts into your daily routine can provide your hair with a broad spectrum of essential nutrients.
How to Maximize Nutrient Absorption
Doshi emphasizes that how you consume your nuts matters as much as which ones you eat.
"Most importantly, soak all of these nuts before consuming to enhance nutrient absorption," he says. Soaking nuts neutralizes certain compounds that can inhibit nutrient uptake, making it easier for your body to utilize the vitamins and minerals they contain.
The Bottom Line
For stronger, shinier, and healthier hair, make nuts a regular part of your diet. Almonds, walnuts, and Brazil nuts provide targeted nutrients for follicle strength, scalp health, and keratin production, while cashews and pistachios offer additional support for fullness and shine.
Consuming just a handful daily—ideally soaked—can help your hair reach its full growth potential. Start small, stay consistent, and let these nutrient-packed nuts work their magic from the inside out. Your hair will thank you.
