Vitamins for Hair Growth: Essential Nutrients for Lustrous Locks

Do you want shiny, healthy hair?

Well, it's not just you; everyone wants smooth, shiny, and long hair. 

Healthy, shiny hair isn’t just a matter of good genetics or expensive haircare products; it’s also heavily influenced by what’s on your plate and in your blood. 

Taking care of your hair is not very difficult; you just need to be consistent and use good products.

The most common causes of hair damage are coloring, artificial supplements, heat damage, and other health problems that cause permanent hair damage.

But what can you do to have healthy, long hair? There is a lot you can do in day-to-day life. You just need to be informed about your hair type, take a good diet that promotes hair health, and what vitamins are good for your hair growth. 

This article discusses some important vitamins for hair growth, how they work, and tips for improving hair growth naturally.

What Are Hair Vitamins?

Hair vitamins are supplements that promote good hair health. No single vitamin can guarantee perfect hair; a combination of key nutrients can reduce hair loss, encourage hair growth, and improve the overall texture of your locks.

Hair is made of a protein called keratin, requiring the right building blocks to grow. Nutrients such as minerals, vitamins, and omega-3 fatty acids nourish the scalp, strengthen hair follicles, and support the natural hair growth cycle. Without these nutrients, your hair might become brittle, thin, or prone to shedding.

However, several products on the market contain similar ingredients, such as biotin, vitamins C and E, folic acid, collagen, and omega-3 fatty acids. They are also rich in additional natural products, such as ashwagandha and ginseng, which some believe can strengthen hair. These products are endorsed by paid celebrities and influencers, not hair experts. Therefore, it is important to understand what product or supplement is best for supporting healthy and strong hair.

Best Vitamins for Hair Growth and Thickness

Here is the list of Vitamins for hair growth and thickness-

Biotin (Vitamin B7)

Biotin is a B vitamin produced by the body. It plays an important role in producing keratin, a primary protein that makes up hair.

Benefits:

• Promotes stronger, thicker hair.

• Reduces hair breakage.

• Enhances the overall health of hair follicles.

Sources:

• Eggs

• Nuts and seeds

• Whole grains

• Sweet potatoes

The FDA does not have a recommended daily allowance (RDA) for biotin. However, most sources state that a daily intake of 30 mcg is sufficient to prevent deficiency. 

Additional Tip: If you notice thinning hair or brittle strands, a biotin deficiency could be the reason. Biotin supplements are widely available, but natural food sources are always preferable.

Iron

Iron is crucial for red blood cells to carry oxygen to the scalp and hair follicles. If you have iron deficiency, your hair follicles may lack the oxygen that is required for healthy growth. Maintaining iron levels is recommended to prevent hair thinning and weakening. 

Benefits of Iron for Hair Growth:

• Prevents hair thinning and shedding.

• Boosts blood circulation to the scalp.

Sources:

• Spinach

• Red meat

• Lentils

• Bell Peppers

• Sweet potatoes

• Chickpeas

• Pumpkin seeds

• Black beans

• Split peas

• Oysters and liver

• Broccoli

• Tofu

• Fortified cereals

Tip: Women are at higher risk of iron deficiency, which can lead to hair loss. A CBC or hemoglobin blood test can help identify if you lack this mineral. 

Zinc

Zinc is important in hair tissue repair, hormone regulation, nutrient absorption, and growth. It also helps control oil production in the scalp, keeping dandruff at bay. If you have zinc deficiency, it may cause hair loss that inhibits the hair growth cycle and cause poor-quality hair. I

Zinc Benefits for Hair Growth:

• It prevents hair follicle weakening.

• Supports the repair of damaged hair.

Food rich in Zinc:

• Shellfish (oysters are particularly rich)

• Pumpkin seeds

• Red meat, poultry

• Oysters

• White beans

• Chickpeas

• Dairy products

• Lentils

• Red kidney beans

• Black beans

• Sesame seeds

Tip: Zinc deficiency can lead to hair loss and scalp issues, so ensure your diet includes zinc-rich foods.

Protein

Hair is made of keratin, a protein that is a major component of your hair. It promotes healthy hair growth. Deficiency of protein weakens your hair and may cause breakage.

Benefits:

• Strengthens hair shafts.

• Promotes hair thickness.

• Makes thick, shiny, and bouncy hair

• Protein reduces hair porosity.

Sources:

• Lean meats

• Eggs

• Dairy

• Legumes

Tip: If you notice hair that easily breaks or lacks luster, it may indicate inadequate protein intake.

Omega-3 Fatty Acids

Omega-3 fatty acids nourish the hair follicles and promote a healthy scalp. Their anti-inflammatory properties can help with issues like dandruff or dry scalp.

Omega-3 Benefits for Hair Growth:

• Adds shine and elasticity to hair.

• It keeps the scalp hydrated.

Sources:

• Fatty fish like salmon, mackerel, and sardines

• Walnuts

• Chia seeds

• Flaxseeds

Tip: Add omega-3-rich foods to your diet, giving your hair a natural shine.

Selenium

Selenium is a powerful antioxidant that protects the scalp from free radical damage. It also plays a role in producing thyroid hormones, which directly affect hair growth. Thus, selenium kills free radicals to promote healthy hair growth. 

Selenium Benefits for Hair Growth:

• Encourages healthy hair follicles and prevents hair loss
• Prevents dandruff.

Sources:

• Brazil nuts (just one nut provides the daily recommended intake)

• Eggs

• Whole nuts

• Garlic

• Beans

• Oatmeal

• Spinach

• Sunflower seeds

• Mushrooms

Tip: Your body requires selenium in small amounts, so avoid over-supplementing, as it can lead to toxicity.

Vitamin E

Vitamin E is another antioxidant vital in maintaining a healthy scalp and promoting blood circulation.

Vitamin E advantages for hair growth:

• Prevents oxidative stress in hair follicles.

• Adds shine and softness to hair.

Sources:

• Almonds

• Avocados

• Sunflower oil

• Peanut butter

• Bell peppers

• Fish

• Spinach

Tip: For an extra boost, you can use vitamin E oil directly on your scalp to improve hydration and circulation.

Recommended Daily Intake

The RDA for Vitamin E is 15 mg (22.5 IU) daily for men and women.

Vitamin A

Vitamin A is important for cell growth, including hair and the tissues in the human body. It also helps the scalp produce sebum, which moisturizes the scalp and keeps hair health in check by fighting off radicals that make hair look flat and weighed down. 

Vitamin A benefits for hair growth:

• Promotes healthy scalp and hair growth.

• It prevents hair from becoming dry and brittle.

Sources:

• Sweet potatoes

• Milk

• Carrots

• Cheese

• Spinach

• Kale

• Oily Fish

• Cod liver oil

• Eggs

Tip: Vitamin A is essential for hair health, but excessive intake can lead to hair loss. Stick to the recommended daily allowance.

Vitamin C

Vitamin C is vital for producing collagen, a protein that strengthens hair. It also helps the body absorb iron, which is crucial for hair growth.

Vitamin C benefits for Hair Growth:

• Vitamin A prevents hair from oxidative stress caused by free radicals.

• Strengthens hair strands and prevents breakage.

• Enhances iron absorption for better oxygenation of hair follicles.

Sources:

Citrus fruits like oranges and lemons
