When you’re suffering from hair loss, no matter the cause, it’s important to take a multi-pronged approach to tackling the problem. And while there’s never one answer for all types of hair loss, there is one factor that you have the power to change: your diet.
The foods you eat have a direct impact on your body’s health and, as a result, the health of your scalp and hair. This is why you may want to consider making some immediate changes to your current diet in favor of one that has more proven health benefits.
In this post, I’ll introduce the various food ‘groups’ that have some scientific basis in promoting a healthy scalp and hair. I’ll then share with you a list of foods you may want to consider adding to your diet, as well as a few supplements.
Let’s jump in!
1. Fibrous Foods
Keeping your colon clean is absolutely essential for fast hair growth and the best way to keep the colon clean is eating food with plenty of fiber in it.
Fibrous foods literally act like a brush, sweeping out the colon with each team time keeping it clean and unblocked. Foods that lack fiber, typically processed and stodgy foods do the opposite.
They move slowly through the digestive tract, sticking and coating everything, leaving a trail of impacted mucus.
This is why refined carbs, plus dairy, plus meat, such as a pizza can leave you feeling so stodgy and fatigued after eating it. Your body finds it hard to digest it and the unnatural combination is sticky and gooey. The perfect combination for blocking the colon.
The foods we’ve been eating for 99.9% of human evolution are naturally high in fiber, but our modern foods get processed and much of the fiber (and natural digestive enzymes) get stripped out in the process.
Without the fiber the foods cling to the colon walls, stopping waste products being excreted and stopping nutrition from our food being absorbed. Both of these can be really bad for hair growth.
Fiber acts as a fuel for the bacteria in our gut. These bacteria produce beneficial metabolites including short chain fatty acids like butyrate which have anti-inflammatory actions.
Fiber also helps eliminate heavy metals and excess cholesterol in the stools.
So which foods are naturally high in fiber?
Almost all natural plant based foods are naturally high in fiber. Beans, nuts, seeds, fruits and dry fruits and vegetables, as well as whole grains and oats all contain the fiber your body needs to keep the colon clean and get the most nutrition out of your food.
2. Probiotic Foods
Fibrous foods aren’t the only ones that you should be adding to your diet. There are many foods that contribute to a healthy gut and, therefore, a healthy body. But the best food for the gut is by and far probiotics.
In short, probiotics are live microorganisms (1). They’re often referred to as your body’s ‘good’ bacteria as they help to support the digestive system.
But what does the gut – or more specifically, the microbiome of the gut – have to do with hair growth?
The reasons why the ‘microbiome’ as scientists call it (the collection of bacteria in our body) is so important for healthy hair growth isn’t quite clear. Though, there is some connecting evidence and, as the researchers put it, probiotics may help “induc[e] beneficial integumentary effects that manifest as luxuriant hair” (2, 3).
Whether probiotics are good for hair growth or not, there is one thing that we know for certain: most of us can benefit from a more healthy bacterial balance.
If you’ve ever taken antibiotics you may have hurt your bacteria. If you were born via cesarean, or even consumed non-organic animal products as they can contain the antibiotics that farmers give their livestock (4).
The other problem is that a lot of foods contain preservatives. And you may know that the point of a preservative is to kill bacteria.
This is great if you want to preserve the shelf life of your processed foods, but the preservatives will kill off the good bacteria in your stomach (5).
Then there is also the problem of yeasty and fiber-less foods. All of these unnatural foods sitting in your digestive tract give the bad bacteria a boost whilst hurting the good bacteria.
So, what is the solution? The best solution is to add healthy probiotic foods to your diet.
Probiotic foods contain naturally-occurring healthy bacteria which can thrive in your digestive tract and help get rid of bad bacteria.
You can introduce powerful probiotics into your diet, and here are some of the best ones that I recommend:
- Miso Soup
- Sour pickles
- Sourdough bread
- Raw cheese
All of these foods contain naturally high amounts of probiotics so try to get two portions of any of these into your diet on a daily basis. Probiotic supplements are also highly recommended.
3. Micro-Nutrient Foods
Your hair needs nutrients and minerals to grow. These are the building blocks from which the hair follicle itself is made. If there aren’t enough of these building blocks then hair growth is stunted, and of course the building blocks come from the food you eat.
Micronutrients are described as the trace minerals, vitamins, amino acids, and phytochemicals that typically come from fruits, vegetables, nuts, seeds, herbs, and spices.
They allow the body to produce complex but crucial substances like enzymes and hormones that help with hair growth
Macronutrients on the other hand are the larger nutrients that we do need, but are found in abundance in our modern diet. These are the protein and carbohydrate.
Our body needs them for energy and muscle growth, but we usually have enough of them in our diet and the abundance of them means we don’t need more for our hair.
But by eating these macronutrients we essentially push out the foods that contain high amounts of micronutrients meaning we could actually be completely undernourished.
When it comes to our hair, it’s important to opt for more micronutrients than macronutrients. Further down on this page you’ll learn about the foods that contain the highest amounts of micro-nutrients.
4. Plant Based Foods
Having gone through the previous 4 guidelines, something becomes apparent – there is a definite emphasis on plant-based foods.
This is because a plant-based diet is more fibrous, more probiotic, and more micronutrient based. The best foods for hair growth are foods from plants that our body can quickly digest and turn into keratin.
When shopping, the more of your shopping basket you can make out of fruits, vegetables, legumes, nuts, and seeds, the better.
These Are The Best Food Groups For Hair Growth
So, what food groups should you consume if you’re interested in a healthy scalp and, hopefully, hair growth?
Pre-Soaked Raw Nuts and Seeds
Raw nuts and seeds are amazing sources of nutrition (6).
They contain proteins, essential fatty acids, omega oils, and trace minerals. When soaked before eating, the life form in the nuts and seeds become activated. Without the pre-soaking there are small amounts of anti-nutrients phytic acid (7).
These chemicals allow the nuts and seeds to survive longer without being eaten by bacteria, while they lie dormant in the ground. But when you soak the seed or nut it removes the chemicals that stop it being digestible and bring it to life, providing you with the ultimate source of nutrition.
The best nuts and seeds for hair growth are:
- Brazil nuts
- Pine nuts
- Flax seeds
- Chia seeds
- Hemp seeds
- Sunflower seeds
- Pumpkin seeds
- Sesame seeds
- Apricot kernels
- Coconuts and coconut oil
Cruciferous vegetables are your best sources of nutrients, trace minerals, and vitamins like folate (8). All of which go on to help with healthy hair growth.
One of the main ways these vegetables help reduce hair fall is through their anti-inflammatory effects. By reducing inflammation in the scalp hairs seem to last longer and stay healthy for longer.
The compounds in cruciferous vegetables have also been proven to protect cells from DNA damage which reduces age related hair loss (9).
Here are a selection of the most common cruciferous vegetables:
- Shepherd’s purse
- Brussels sprouts
- Chinese cabbage
- Collard greens
- Bok choy
- Land cress
- Mustard greens
- Daikon radish
Beans, Peas, and Lentils
Legumes, consisting of beans, peas, and lentils are nature’s ultimate protein sources, perfect for natural, bioavailable sources of hair building keratin (10).
If your hair feels thin and lifeless, or if it falls out easily and grows slowly, then upping the amount of plant-based protein from these 3 sources will definitely help.
Soaking, sprouting, and boiling must be used with most legumes.
- Kidney bean
- Navy bean
- Pinto bean
- Haricot bean
- Lima bean
- Butter bean
- Adzuki bean
- Azuki bean
- Mung bean
- Golden gram
- Green gram
- Black gram
- Scarlet runner bean
- Moth bean
- Tepary bean
- Broad beans
- Garden pea
Herbs and Spices
Herbs and spices contain some of the most concentrated forms of antioxidants of any foods (11). These antioxidants reduce free radicals; free radicals that cause cellular and genetic damage and increase aging (12). Therefore antioxidants may increase hair growth by reducing the free radicals that cause age related hair loss.
The best spice for your hair is turmeric, and there are plenty of others such as ginger, basil, cloves, pepper, vanilla, cinnamon, cayenne pepper, and many more.
My Favorite Food Supplements
It’s best to consume as much of your required nutrients and minerals through your regular diet. However, this isn’t always easy, and that’s where food supplements come in.
Pea and hemp protein
Pea and hemp protein are great natural, plant-based sources of protein (as opposed to whey protein which is made from dairy) that are extremely high in omega acids and fiber. Hair needs keratin, which is a protein, to grow and both hemp and pea are great sources of protein. I usually add these to my morning smoothie.
Spirulina and Chlorella
Spirulina and chlorella are two amazing food sources that are packed full of micronutrients, and also very importantly, loaded with chlorophyll.
Chlorophyll is an interesting compound because it is almost identical to hemoglobin in composition. The only difference being that chlorophyll has a molecule of magnesium, whereas haemoglobin has a molecule of iron.
This is why low ferritin levels can sometimes lead to hair loss, because oxygen supply to the root of the hair follicle is diminished through lack of hemoglobin.
Hemoglobin is the part of blood that is responsible for carrying oxygen, and a lack of hemoglobin in the blood causes severe decrease in oxygen blood content.
Spirulina and chlorella also contain their own self-digesting enzymes so they deliver vital nutrients and minerals to the body and the hair without taxing the digestive system.
I highly recommend adding these and other greens supplements like wheatgrass powder to your morning smoothie or taking them every day as a supplement.
A diet change alone will not stop your hair loss, or even promote hair growth. However, it’s a step in the right direction.
Do you need to add in all of the foods mentioned above? Not right away, but it never hurts to diversify your diet and you can easily do so with the lists I’ve provided.
And remember: hair growth is about so much more than just your diet. There is very likely an underlying issue – one not directly linked to food intake – that is driving your hair loss. It’s important to find and target this issue now before the problem becomes irreversible.
