Best Foods for Hair Growth: What to Eat for Stronger, Thicker Hair

Best Foods for Hair Growth: What to Eat for Stronger, Thicker Hair

Most men look for magic serums, pills, or treatments for hair loss. Few ask the more important question — what is your hair actually made of? And are you eating enough of it?

Hair is built from protein, minerals, and healthy fats. It grows slower, weaker, and thinner when your diet is trash — even if you’re using all the right products externally.

If you want better hair, start with your plate.

Here’s exactly what to eat if you want stronger, thicker, healthier hair for the long term.

The Critical Nutrients Your Hair Needs

Protein (Especially Collagen)

Hair is primarily made of a protein called keratin. If your protein intake is low, your hair has nothing to build with. Collagen, in particular, supports the structure of the hair follicle and improves scalp elasticity.

Best sources:

  • Grass-fed collagen powder

  • Bone broth

  • Steak, chicken, fish

  • Eggs

Aim for at least 1 gram of protein per pound of bodyweight daily.

Zinc

Essential for hair follicle repair, DHT regulation, and scalp health. Zinc deficiency is common in men, especially those who train hard or sweat a lot.

Best sources:

  • Oysters

  • Grass-fed beef

  • Pumpkin seeds

  • Eggs

Supplement if needed, but food-first is always better.

Magnesium

Supports stress regulation, sleep, and hormonal balance. Hair loss is often worsened by chronic stress and poor recovery.

Best sources:

  • Dark leafy greens

  • Pumpkin seeds

  • Almonds

  • Dark chocolate (real, not candy)

Omega-3 Fatty Acids

Fights inflammation in the scalp, improves blood flow, and supports follicle health.

Best sources:

  • Wild-caught salmon

  • Sardines

  • Mackerel

  • Fish oil supplements (high quality only)

Iron

Low iron weakens hair structure and slows growth. Especially critical if you’re vegetarian or eat low-meat diets.

Best sources:

  • Red meat

  • Liver

  • Spinach

  • Lentils

Vitamin C

Supports collagen production and iron absorption.

Best sources:

  • Citrus fruits

  • Bell peppers

  • Berries

  • Kiwi

What to Avoid for Hair Health

If you’re eating right but still hammering your body with garbage, progress will be slow or nonexistent.

Avoid:

  • Seed oils (canola, soybean, sunflower)

  • Processed junk food

  • Excessive sugar

  • Alcohol (dehydrates scalp, disrupts hormones)

  • Caffeine overload without adequate hydration

Sample Hair Growth Diet for a Day

Breakfast:

  • 4 eggs cooked in grass-fed butter

  • Bone broth with collagen powder

  • Berries

Lunch:

  • Grass-fed steak

  • Spinach salad with olive oil

  • Pumpkin seeds

Snack:

  • Greek yogurt with dark chocolate and honey

  • Orange slices

Dinner:

  • Wild-caught salmon

  • Roasted sweet potatoes

  • Broccoli

Optional:

  • Zinc + Magnesium supplement before bed

  • Fish oil with dinner

Nutrition Will Not Save Dead Follicles

Eating for hair health is powerful — but it’s not a replacement for blocking DHT if you’re already thinning.

Nutrition builds stronger, healthier new growth. It fuels scalp recovery. It makes your topical stack work better.

But if your temples are receding or your crown is thinning, you still need:

  • RU58841 (blocks DHT locally)

  • Caffeine + peppermint oil (boosts circulation)

  • Microneedling (stimulates growth)

Food is your foundation. Treatments are your tools.

Handle both.
