Hair growth and thickness are influenced by various factors, including genetics, hormones, diet, and overall health. While proper hair care is essential, sometimes it’s not enough to achieve the desired hair results. This is where supplements come in. Certain vitamins and minerals can support hair health, boost growth, and enhance thickness. If you’re looking to improve the health of your hair, here are some of the best supplements for hair growth and thickness.

Best Supplements for Hair Growth and Thickness

1. Biotin (Vitamin B7)

Biotin, also known as Vitamin B7, is one of the most popular and well-known supplements for hair growth. Biotin is a water-soluble vitamin that plays a key role in the health of your hair, skin, and nails. It supports keratin production, a protein that makes up the structure of hair strands and can help to improve the strength and thickness of your hair.

Benefits:

• Promotes healthy hair growth
• Improves hair strength and reduces breakage
• Supports overall hair health

How to Take It: Biotin is commonly found in hair growth supplements, either as a standalone supplement or in combination with other vitamins and minerals. Typical dosages range from 30 to 100 micrograms daily, but higher doses are available.

2. Collagen

Collagen is the most abundant protein in the body, and it plays a crucial role in maintaining the health of your skin, hair, and nails. As we age, collagen production decreases, which can lead to thinner hair and reduced hair growth. Taking collagen supplements can help restore these levels, promoting stronger, thicker hair.

Benefits:

• Improves hair elasticity and strength
• Reduces hair thinning and breakage
• Enhances overall scalp health

How to Take It: Collagen supplements come in powders, capsules, and liquid forms. For hair growth, it’s typically recommended to take 1–2 tablespoons of collagen powder per day, mixed with your favorite beverage.

3. Vitamin D

Vitamin D is essential for overall health, and studies have shown that a deficiency in Vitamin D can contribute to hair loss. This vitamin helps regulate hair growth by influencing the hair follicles, and it may play a role in the hair growth cycle.

Benefits:

• Supports the hair growth cycle
• Reduces the risk of hair shedding
• Promotes follicle health

How to Take It: Vitamin D can be taken as a daily supplement in capsule or liquid form. The recommended daily intake for adults is 600 to 800 IU, but this can vary depending on individual needs and current vitamin D levels.

4. Iron

Iron deficiency is one of the most common nutritional deficiencies linked to hair loss, especially in women. Iron helps carry oxygen to your hair follicles, promoting healthy hair growth. If your iron levels are low, your hair follicles may not get the nutrients they need, which can result in hair thinning or shedding.

Benefits:

• Promotes healthy hair growth
• Prevents hair loss caused by iron deficiency
• Improves circulation to hair follicles

How to Take It: Iron supplements are widely available in both ferrous sulfate and ferrous gluconate forms. The typical recommended dose is 18 mg per day for women, but higher doses may be needed for those with iron deficiency.

5. Zinc

Zinc is an essential mineral that plays a vital role in hair tissue growth and repair. It also helps maintain the oil glands around the hair follicles, which are crucial for hair health. Zinc deficiency can lead to hair loss, thinning, and poor scalp health, so maintaining proper levels is essential for thick, healthy hair.

Benefits:

• Promotes healthy hair growth and repair
• Supports the production of keratin
• Reduces dandruff and scalp inflammation

How to Take It: Zinc supplements typically come in tablet or capsule form. The recommended daily intake is around 11 mg for men and 8 mg for women. However, it’s important not to take too much zinc, as excess zinc can interfere with the absorption of other important minerals like copper.

6. Omega-3 Fatty Acids

Omega-3 fatty acids are healthy fats that play a role in maintaining a healthy scalp and supporting hair growth. These essential fats help nourish hair follicles, prevent dryness, and promote the production of oils that keep the scalp hydrated.

Benefits:

• Improves scalp health and hydration
• Reduces inflammation that may inhibit hair growth
• Supports hair follicles for stronger hair

How to Take It: Omega-3 supplements come in the form of fish oil or plant-based alternatives like flaxseed oil. It’s generally recommended to take 1–2 grams per day.

7. Saw Palmetto

Saw palmetto is a plant extract that has gained popularity for its potential to block DHT (dihydrotestosterone), a hormone linked to hair loss, particularly in men. By inhibiting DHT, saw palmetto may help reduce hair thinning and support hair regrowth.

Benefits:

• Helps block DHT, preventing hair loss
• Improves overall scalp health
• Reduces the appearance of thinning hair

How to Take It: Saw palmetto is available in capsule, softgel, and liquid extract forms. The typical dose ranges from 160 to 320 mg per day.

8. Vitamin E

Vitamin E is a potent antioxidant that helps protect hair follicles from oxidative stress caused by free radicals. It also helps improve circulation in the scalp, ensuring that your hair follicles receive the nutrients they need for optimal growth.

Benefits:

• Protects hair follicles from oxidative damage
• Improves scalp circulation
• Enhances hair strength and shine

How to Take It: Vitamin E supplements come in softgel or liquid form. The recommended daily dosage for adults is 15 mg, which is equivalent to 22.4 IU.

9. Folate (Vitamin B9)

Folate, also known as Vitamin B9, is essential for overall cell growth and repair. It is particularly important for healthy hair because it supports the creation of new cells in the hair follicles. Folate deficiency has been linked to hair loss, so maintaining optimal levels is key to achieving thick, strong hair.

Benefits:

• Stimulates hair follicle growth
• Supports overall hair health
• Reduces hair thinning caused by nutrient deficiencies

How to Take It: Folate supplements are available in both tablet and liquid forms. The recommended daily intake for adults is 400 mcg.

4. Are there any side effects of hair growth supplements?

Generally, hair growth supplements are safe when taken as directed. However, taking excessive amounts of certain vitamins and minerals, like iron or vitamin A, can cause side effects such as digestive issues, headaches, or toxicity. It’s important to follow the recommended dosage and consult with a healthcare provider before starting any supplement regimen.

5. Can I take multiple hair growth supplements at the same time?

Yes, you can take multiple hair growth supplements, as long as you follow the recommended dosages for each. Many hair growth supplements contain a blend of vitamins and minerals designed to work synergistically. However, it’s essential to avoid exceeding the safe limits for specific nutrients (e.g., zinc or vitamin A).

6. Will taking hair growth supplements make my hair thicker?

Hair growth supplements can help improve the strength, thickness, and overall health of your hair. Nutrients like biotin, collagen, and omega-3 fatty acids contribute to thicker hair by nourishing hair follicles and promoting a healthy scalp environment.

7. Can I get all the necessary nutrients for hair growth from food instead of supplements?

Yes, you can get many of the essential nutrients for hair growth from a balanced diet. Foods rich in biotin (like eggs and nuts), vitamin D (like fatty fish and fortified foods), and omega-3s (like salmon and flaxseeds) can support healthy hair growth. However, if you have a specific deficiency, supplements may be a more effective way to boost hair health.

Supplements can provide the necessary nutrients to strengthen hair, prevent thinning, and promote healthy regrowth. Whether you’re dealing with hair loss or simply want to enhance your hair’s thickness, incorporating these supplements into your routine could help you achieve your hair goals. However, always consult with a healthcare provider before starting any new supplement regimen to ensure it’s the right fit for your specific needs.
