Hair Health
Description
This page has 60 references
"Hair Health" is the overall state of strength, resilience, and appearance of each strand, influenced by nutrients, hydration, and daily care. Poor hair health often presents as dryness, brittleness, thinning, or increased shedding. Diets lacking key vitamins or excess heat styling can weaken the hair structure over time. Strengthening hair involves nutrient-rich foods, proper hydration, scalp care, and protective routines. Avoiding harsh chemicals and supporting protein synthesis helps maintain vibrant, healthy growth and reduces the risk of long-term damage.

Things To Do
For healthy hair, make sure to follow the following dietary recommendations:
Eat a whole-foods-based diet rich in vegetables, fruits, whole grains, healthy protein, and fatty acids.
A sufficient intake of protein helps prevent dry and brittle hair.
include foods rich in B vitamins, especially B6, B12, and folic acid.
incorporate vitamin C-rich foods, such as bell peppers, tomatoes, cruciferous vegetables, dark leafy greens, citrus fruits, berries, kiwis, etc.
eating zinc-rich foods, such as shellfish, meat, eggs, nuts, seeds, etc.
incorporating foods high in iron. Heme iron [obtained from animal sources] is much better absorbable than nonheme iron from plant sources.
Consume foods high in omega-3 fatty acids, such as cold-water fatty fish, seafood, flaxseed oil, avocados, nuts, seeds, etc.
include silica-rich foods, such as dark leafy greens, green beans, lentils, brown rice, bananas, etc.
Stay hydrated and drink quality water, such as mineral water.
Furthermore, the following practices promote hair health:
using mild and non-toxic shampoos and conditioners.
gentle brushing. Use a brush that has flexible bristles, such as a boar bristle brush. It will minimize hair damage.
blow-dry your hair. Make sure, however, that the temperature of the air isn't too hot, and end it when your hair is 90% dry.
Use a hair wrap or a scarf to protect your hair against damage while you are sleeping.
regularly trim split ends to promote hair health.
Things To Avoid
The following dietary choices do not support hair health:
processed, junk, and fast foods.
sugar, sugary snacks, desserts, and sugary beverages.
refined carbohydrates.
low-fat diet, which can lead to brittle and dry hair.
excessive alcohol consumption.
dehydration.
undereating and drastic calorie restriction.
foods, especially fish and seafood, high in mercury.
foods you are allergic to or intolerant of.
Furthermore, avoid the following:
too frequent wahsing. It can cause dry, brittle hair and irritate the scalp. Wash your hair 2-3 times a week.
high-heat hair treatments such as hair straighteners, curlurs, etc.
harsh chemicals.
pulling your hair and wearing it in a high, tight ponytail or bun.
getting your hair wet in swimming pool water. Chlorine is highly damaging. Make sure to use a protective cap.
medications that can cause hair loss, such as antibiotics, anticoagulants, antisepressants, endocrine drugs, chemotherapy drugs, and more.
Supplements
Direct Support
(Most Helpful → Least Helpful)
These supplements directly support hair health by nourishing hair follicles, promoting growth cycles, and supporting the structural integrity of hair strands.
Iron: Iron enhances blood circulation and oxygen delivery to hair roots, which accelerates hair growth and helps maintain stronger, longer hair. Adequate iron levels are key to reducing hair thinning and promoting healthy strands.
Zinc: Zinc deficiency can trigger hair loss similar to iron deficiency. Zinc also protects the integrity of existing hair, preventing breakage and supporting overall hair strength and health.
Vitamin D: Vitamin D supports keratinocytes, the skin cells that produce keratin, which is essential for regulating hair growth and shedding. Adequate levels of Vitamin D contribute to stronger, healthier hair follicles.
Vitamin B Complex: Vitamin B complex supports hair growth by promoting red blood cell production, which ensures oxygen delivery to the scalp. Biotin, in particular, plays a key role in preventing hair thinning and enhancing overall hair strength.
Collagen: Collagen peptides strengthen hair follicles, improve elasticity, and enhance scalp health. By promoting collagen synthesis, they reduce breakage and support thicker, healthier hair.
Silicon Dioxide [Silica]: Silica strengthens hair strands from within, improving texture and reducing breakage. By supporting the structural integrity of hair, silica helps promote thicker, healthier-looking strands.
Indirect Support
