author avatar Dr. Eric Berg 03/06/2024

Thicker hair growth is a highly sought-after goal for many individuals. Nevertheless, obtaining the desired hair thickness can be difficult due to heredity, hormonal discrepancies, and environmental influences.

Learn about the essential nutrients needed to promote thicker hair growth and discover how proper diet and hair care practices can help achieve this goal.

The Role of Nutrients in Hair Health

The first step in getting healthier hair is to ensure your hair's health is optimized by the inclusion of iron, zinc, omega-3 fatty acids, vitamin D, selenium, biotin, folate, and vitamin C in your diet.

Iron: Red Meat and Eggs

Iron is crucial for healthy hair, so eat plenty of iron-rich foods like red meat and eggs to prevent breakage and brittleness.

Zinc: Shellfish and Red Meat

Zinc supports healthy hair follicles, so add shellfish and red meat to your diet to keep your strands strong.

Omega-3 Fatty Acids: Salmon and Cod Liver Oil

  • Fish: Oily fish like salmon, mackerel, and sardines are excellent sources of omega-3s.

  • Nuts & Seeds: Chia seeds, flaxseeds, and walnuts are also rich in omega-3s.

How to Promote Thicker Hair Naturally

Want luscious locks? Here are some tips to help you achieve thicker hair naturally.

Incorporate Sea Kelp into Your Diet

Sea kelp is a natural source of iodine and essential minerals that support hair growth.

Avoid Over-Washing Your Hair

Washing your hair frequently can strip away its natural oils, leading to dryness and breakage. Limit washes to no more than two or three times a week, and use lukewarm water for rinsing instead of hot water, which can damage your hair.

Use Sulfate-Free Shampoo and Conditioner with Clean Ingredients

  • Sulfates in some shampoos may cause irritation and damage; choose sulfate-free options with clean ingredients like aloe vera or chamomile extract.

  • Be critical of popular name-brand hair care products. Learn the truth and find out if Pantene is good for your hair. Choose conditioners containing essential oils such as argan or coconut oil to nourish your tresses further.

Install a Water Filter in the Shower

Chlorine and hard minerals in tap water can weaken your hair. Installing a shower filter can help reduce exposure to these harmful elements, promoting healthier hair growth.

Opt for Non-Toxic Dye When Coloring Your Hair

Hair dyes with harsh chemicals may cause damage and thinning. Choose non-toxic options such as henna or plant-based dyes that are gentler on your locks. If possible, avoid coloring your hair altogether to help prevent unnecessary damage from occurring.

Lower Stress Levels Through Relaxation Techniques

Stress can negatively impact hair health by disrupting its natural growth cycle. Incorporate relaxation techniques and deep breathing exercises into your daily routine to manage stress levels effectively.

Quit Smoking

Studies have shown that smoking is linked to poor scalp circulation and reduced nutrient delivery to hair follicles. Quitting this habit will improve overall health and contribute positively towards achieving thicker tresses over time.

The Importance of Protein for Healthy Hair Growth

Keratin, a protein that makes up most of our hair structure, is essential for healthy growth and maintenance.

A lack of protein can lead to weak, brittle hair and hair loss, so regularly consume high-quality sources like grass-fed meats or eggs.

Recommended Protein Sources for Optimal Hair Health

  • Eggs: Rich in biotin and other B vitamins crucial for hair health, eggs also provide an excellent source of complete proteins containing all nine essential amino acids.

  • Fish: Fatty fish like salmon or mackerel are packed with omega-3 fatty acids that help support a healthy scalp environment while also being excellent sources of lean protein. Be sure to consume fish that are wild-caught rather than farm-raised.

  • Poultry: Chicken and turkey offer high-quality proteins as well as B vitamins.

Incorporating these nutrient-dense foods into your diet can help supply the necessary elements for hair growth and sustenance, which leads to improved tresses.

Stress Less for Better Tresses

Stress can mess with your hair, making it thin and lifeless, but you can fight back with relaxation techniques to help you feel better and look better.

Stress and Hair Loss

Stress can cause cortisol levels to rise, disrupting your hair follicles' natural growth cycle and leading to shedding or even temporary hair loss. Inflammation caused by stress can also damage follicles and prevent healthy regrowth.

Relaxation Techniques to Reduce Stress

  • Exercise: Physical activity combats stress and improves overall health.

  • Sleep: Prioritize sleep to help your body recover and produce the hormones for healthy hair.

  • Hobbies: Pursuing hobbies can provide an outlet for creative expression and take your mind off worries.

Incorporating the above activities regularly into your lifestyle can greatly reduce stress, thus improve the health of your hair follicles.

Choosing Safe Hair Products and Treatments

Want luscious locks without damaging your hair? Choose hair products with gentle ingredients that nourish each strand and provide necessary hold strength during styling sessions.

Selecting Sulfate-Free Shampoos with Natural Ingredients

Sulfates can strip your hair of natural oils, leading to dryness and breakage. Opt for sulfate-free shampoos that use milder cleansing agents derived from natural sources like coconut oil.

Benefits of Using a Conditioner Containing Essential Oils and Fats

Conditioners enriched with essential oils like argan, jojoba, or avocado oil help lock in hydration while promoting overall hair health. Incorporating fatty acids like omega-3s in fish oil supplements or flaxseed oil can also support strong follicles.

Avoiding Harsh Chemicals in Hair Dye

  • Ammonia: A common ingredient in hair dyes that can cause scalp irritation and weaken the hair shaft. Opt for ammonia-free alternatives to minimize damage.

  • Parabens: These preservatives have been linked to hormone disruption and should be avoided when possible. Look for paraben-free products instead.

  • P-phenylenediamine (PPD): A chemical used in many permanent hair dyes, but it's also known as a skin irritant and allergen. Choose PPD-free options or consider using henna-based natural pigments, which are less likely to cause reactions.

By making sure your shampoo does not contain the above ingredients, ensuring your diet is full of the nutrients, using stress relief techniques, and not over-washing, you are on the right path to gaining and maintaining a thick and healthy head of hair.
