You've probably seen your favorite celebrities' long, luscious locks and wondered how they get their hair to look so thick and full. When you have great hair, you don't think about it.

When you don't, you think about it a lot. That's the struggle that is hair loss.

However, there are several things you can do to boost your chances of having fuller locks. Fortunately enough, several supplements can help promote hair growth and thickness too! Read on to learn more about them.

What causes hair to be thin

If you're wondering why your hair is thinning, you first must determine the cause. You don't want to treat the symptom. You need to figure out the real problem at the root of it all.

Several common reasons for thinning hair include stress, poor diet, certain medications, genetics, and more. You can rule out genetics as a cause if you have thinning hair.

Stress-induced hair thinning is caused by cortisol, a hormone released by the body in response to stress that triggers a chain of events that can lead to hair loss. A poor diet will leave you deficient in zinc, iron, and biotin, the three nutrients necessary for healthy hair.

If you're taking certain medications, you risk experiencing hair loss as a side effect. If you're on any of the following drugs, you risk losing some of your hair – corticosteroids, anticonvulsants, anticoagulants, and diabetes medications. 

Reshape your diet

Your diet is the foundation for your entire body, and the same holds for your hair. You can only grow hair if your diet has the nutrients and vitamins necessary to create new hair.

If you want thicker hair, you must eat foods and supplements rich in biotin, iron, and zinc. And what's more, your body requires a variety of nutrients from different groups (vitamins, minerals, proteins, and fats). Consuming a single food that contains a specific vitamin or mineral isn't enough to meet your body's daily requirements.

Collagen

Clinical studies have proven that collagen supplements help improve the health and structure of your hair. With daily use, you can expect your hair to grow faster and become thicker. You can also use it to tame frizzy or unmanageable hair and to reduce split ends.

Applied to the skin, it can be used as an anti-aging treatment that also reduces the appearance of wrinkles and stretch marks. The best part is that you can use this with other hair growth supplements. 

B-vitamins

B vitamins are essential for cell growth and metabolism, which are necessary for hair growth. B vitamins can be found in various foods, such as leafy greens, legumes, eggs, and meat. Consider taking a supplement if you need more B vitamins from your diet.

Vitamin C

When it comes to vitamins for hair growth, vitamin C is one of the most essential. Vitamin C helps to stimulate blood flow to the scalp and promote collagen production, both of which are necessary for healthy hair growth. You can find vitamin C in citrus fruits, bell peppers, broccoli, and Brussels sprouts.

It helps with collagen production, which is essential for hair growth. Vitamin C also helps to protect your hair from damage and keeps your scalp healthy.

You can find vitamin C in citrus fruits, strawberries, bell peppers, broccoli, and tomatoes. You can also take a supplement. Aim for 1000-2000 mg per day.

Iron

If you're looking for a way to naturally get fuller and thicker hair, consider taking an iron supplement. Iron is essential for hair growth and can lead to hair loss if you need to get more of it in your diet. If you think you may be iron-deficient, talk to your doctor about taking a supplement.

Zinc

Zinc is an essential mineral for hair growth and thickness. It plays a role in cell growth and helps keep hair follicles healthy. Zinc also helps the body absorb other vital nutrients, such as vitamin A, for hair growth.

Foods high in zinc include oysters, beef, lamb, pumpkin seeds, and nuts. You can also take zinc supplements to ensure you get enough of this critical mineral.

Vitamin D

Vitamin D is another crucial vitamin for hair health. It helps your body absorb calcium, which is essential for healthy hair growth. Vitamin D also helps to reduce inflammation and keep your scalp healthy.

You can get vitamin D from spending time in the sun or taking a supplement. Aim for 1000 IU (international units) per day.

Folic acid

This vitamin is vital for cell growth and metabolism. It's found in leafy green vegetables, legumes, and fortified foods. Folic acid is sometimes used as a supplement to treat anemia.

Biotin

Biotin: Often called "hair vitamin," biotin is a water-soluble vitamin that's part of the B-complex vitamins. It's found in eggs, salmon, avocado, and nuts. Biotin is thought to improve the strength and quality of hair and nails.

Magnesium

Most people, including otherwise healthy people, don't get enough magnesium in their diet. The recommended amount of magnesium is around 400 mg daily for men and about 310 mg daily for women. You can find magnesium in various foods, including spinach, nuts, seeds, coconuts, and legumes.

If your diet lacks magnesium, you can take a supplement to get your daily requirement. Magnesium is necessary for more than 300 biochemical reactions in the body, including synthesizing DNA, activating vitamin D, breaking down carbohydrates, creating proteins, synthesizing fatty acids, and activating neurotransmitters.

Omega-fatty acids for hair growth

A few supplements on the market claim to help with hair growth and thickness. One of these is omega-fatty acids. Omega-fatty acids are a type of unsaturated fat that is essential for human health.

They can be found in fish, nuts, and seeds. Some studies have shown that omega fatty acids can help with hair growth. In one study, people who took an omega-3 supplement for four months had a 25% increase in hair growth.

There is also some evidence to suggest that omega-3 fatty acids can help with hair thickness. In one study, people who took an omega-3 supplement for six months had a 13% increase in hair thickness.

Conclusion

There are many reasons for thinning hair, but the good news is that most of them are preventable. You can make your hair healthier by eating a nutritious diet and taking the right supplements.

To thicken your hair, you must ensure that you eat well and take the right accessories. It will take some time to see results, but you'll be glad you put in the effort when you see how healthy and thick your hair has become!
