It can be found in many foods such as sweet potatoes, carrots, spinach, and eggs.

Vitamin A is also available in supplement form but it’s important to speak with a healthcare provider before starting any supplement regimen.

This is especially true if you already take other medications or have any underlying health conditions that may interact with the supplement.

Additionally, taking too much of a vitamin A supplement can lead to toxicity so it’s important to talk to your doctor about the right dosage for you.

Vitamin A supplements are available over-the-counter but should not be taken without speaking to a healthcare professional first.

Vitamin B

There are several types of vitamin B that are important for healthy and strong hair, including Vitamin B-12, Vitamin B-9 (also known as folate), and Vitamin B-7 (biotin).

Vitamin B-12 can be found in animal products such as meat, eggs, and dairy.

Folate or vitamin b9 can be found in leafy green vegetables like spinach and kale, nuts like almonds or walnuts, and seeds such as sunflower or pumpkin.

Similarly biotin or vitamin b7 is also present in these same food sources.

These vitamins are also available in supplement form but before starting any supplement regimen please speak with your healthcare provider to discuss if they would be beneficial for you specifically.

Vitamin C

Vitamin C is an incredibly powerful antioxidant that helps to support collagen production and healthy blood flow to the scalp.

This can be extremely beneficial for stimulating hair growth, as increased blood circulation can help nourish the scalp and increase nutrient delivery throughout the body.

Vitamin C can be found in a variety of foods, such as oranges, strawberries, peppers, kiwi fruits, leafy greens like kale or spinach as well as broccoli or Brussels sprouts.

Additionally you may want to consider taking a supplement form of vitamin c if you feel your diet does not provide enough for optimal health benefits.

Taking high quality supplements with added minerals and nutrients is usually the best way to ensure you are getting all that you need when it comes to vitamins and minerals needed for overall health including hair growth.

Vitamin D

It can be found naturally in fatty fish, egg yolks, and mushrooms.

The body also produces Vitamin D when the skin is exposed to sunlight.

If you are looking for a supplement form of Vitamin D, it’s recommended that you speak with a healthcare provider before beginning any supplementation regimen as too much Vitamin D can lead to adverse health effects.

Additionally, individuals who have dietary restrictions due to allergies or other medical conditions may need to pay special attention to their vitamin intake and seek out appropriate alternatives from their healthcare provider.

Vitamin E

Vitamin E is an antioxidant that can help improve blood flow to the scalp, which is essential for hair growth.

It can be found naturally in many nuts and seeds, as well as leafy green vegetables like spinach and kale.

Vitamin E supplements are also available if you want to get a more concentrated dose of this important nutrient.

Studies have shown that taking a vitamin E supplement regularly can help promote thicker, healthier hair growth.


Iron is an essential mineral for healthy hair growth, as it helps to ensure that the hair follicles receive enough oxygen.

This is because iron plays a key role in the production of red blood cells; without enough of these cells, the follicles won’t get enough oxygen and will be unable to grow properly.

Iron deficiency can lead to thinning hair or even baldness in extreme cases, so it’s important to make sure you are getting enough iron through your diet or with supplements if necessary.

Fortunately, increasing your dietary intake of iron-rich foods or taking an iron supplement may help restore healthy levels of this important mineral and help prevent further hair loss.

Iron-rich foods include dark leafy greens such as spinach and kale; red meat like beef, pork or lamb; seafood such as oysters or clams; nuts and seeds including pumpkin seeds; legumes like lentils or black beans; and fortified cereals or breads.

If you’re considering taking an iron supplement it’s always best to check with your doctor first for proper dosing recommendations based on your individual needs.

Foods rich in iron include red meat, poultry, and beans.


It helps to promote the production of collagen, which acts as the “glue” that holds our skin and body together.

Collagen also helps to keep our hair strong and healthy by providing it with structure.

In addition, zinc plays an important role in producing keratin, a protein found in hair, nails, and skin that strengthens these structures and prevents breakage.

A zinc deficiency can cause the hair to become thin, brittle, and slow its rate of growth.

This makes it important for people with thinning or balding hair to make sure they are getting enough of this vital mineral in their diet.

Foods such as red meat, dairy products, legumes, nuts and seeds all contain zinc which can help prevent deficiencies if eaten regularly.

Supplements may be necessary if dietary sources are not adequate enough to provide proper amounts of zinc each day.
