The Power of Dietary Changes for Hair Health

Robin McIntyre • March 14, 2024

There's an old saying, "you are what you eat." But have you ever given a thought to the fact that your hair could also be a reflection of your diet? The health of our hair is influenced by the nutrients we consume. So, if you're struggling with hair loss or thinning, it might be time to look at your plate. In this blog post, we'll delve into the fascinating world of dietary changes for hair health, backed by scientific studies and expert opinions.


Understanding the Basics of Hair Health


Our hair is primarily made up of protein, specifically keratin. This means that a diet lacking in protein can lead to weak, brittle hair and in severe cases, hair loss. Besides protein, vitamins and minerals like iron, vitamin D, biotin, and zinc also play a crucial role in maintaining hair health.


Factors such as age, genetic make-up, hormonal fluctuations, stress, and some medical issues can also affect the condition and growth of our hair. However, one aspect that we can manage effectively is our nutritional intake.


The Connection Between Diet and Hair Health


It's no surprise that a balanced diet contributes to overall health, but how exactly does it impact our hair? A nutrient-rich diet ensures the hair follicles receive the nourishment they need to grow and stay healthy. When we deprive our bodies of certain nutrients, our hair health can take a hit.


Let's look at some dietary changes for hair health you can implement to boost the strength, shine, and thickness of your hair.


  • The Role of Protein

As mentioned earlier, our hair is predominantly made up of protein. So, incorporating enough protein into your diet can help enhance the health and thickness of your hair. Foods high in protein include lean meats, fish, eggs, dairy products, and plant-based sources like lentils, chickpeas, and quinoa.

  • The Importance of Iron

Iron plays a significant role in maintaining hair health. Its function is to assist red blood cells in delivering oxygen to our body's cells, including those of the hair follicles. Insufficient iron intake can result in anemia, a condition associated with hair loss. Hence, it's important to incorporate foods rich in iron, such as red meat, spinach, kale, and iron-enriched cereals, into your dietary routine.

  • Vitamins for Vibrancy

Certain vitamins are essential for maintaining hair health. Vitamin A, for example, aids in the production of sebum, which keeps our hair moisturized and healthy. B-vitamins, particularly biotin, are known for their role in hair growth. Vitamin D promotes the creation of new hair follicles, while vitamin E protects the hair from damage.

  • The Power of Zinc

 Zinc, an essential mineral, is instrumental in fostering the development and restoration of hair tissues. It's also crucial for maintaining the function of the oil glands surrounding the hair follicles. A deficiency in zinc often manifests as hair loss. To boost your zinc intake, consider incorporating foods like oysters, beef, spinach, wheat germ, pumpkin seeds, and lentils into your diet.

  • Omega-3 Fatty Acids

Omega-3 fatty acids, which our bodies can't generate on their own, must be sourced from our diet. These essential fats offer an array of health advantages, including enhancing the health of our skin and hair. Omega-3s contribute to hair nourishment, aid in thickening the hair, and reduce inflammation that could result in hair loss. Foods rich in Omega-3 include oily fish like salmon and mackerel, flaxseeds, walnuts, and chia seeds.

  • Hydrate For Healthy Hair

Water makes up almost 25% of the weight of a single strand of hair. Staying hydrated can therefore help with scalp health and hair growth. While there's no magic number for the amount of water you should drink, a good rule of thumb is to listen to your body and drink when you're thirsty.

  • The Power of Whole Foods

Not only can processed foods harm your general health, but they can also affect the condition of your hair. Whole foods are brimming with essential nutrients that your hair requires to maintain its strength and vitality. By including a diverse range of fruits, vegetables, lean proteins, and whole grains in your meals, you can guarantee that your diet provides the ideal balance of nutrients for the best possible health of your hair.

  • Superfoods for Super Hair

Certain foods are particularly beneficial for hair health. These include eggs, which are rich in protein and biotin; berries, loaded with beneficial vitamins and antioxidants; spinach, providing iron, folate, and vitamin A; and avocados, an excellent source of vitamin E and healthy fats. Regularly incorporating these superfoods into your diet can contribute significantly to improving your hair health.


Remember, dietary changes for hair health aren't about quick fixes. It's about adopting a healthier lifestyle that supports the health of your hair in the long run. While it's important to incorporate nutrient-rich foods into your diet, it's equally important to manage stress, get regular exercise, ensure adequate sleep, and avoid harmful hair practices like excessive heat styling or tight hairstyles.



Dietary Changes for Hair Health: What to Avoid


When it comes to maintaining healthy hair, diet plays a pivotal role. While some foods can enhance the health and vitality of your hair, others might be detrimental. Consuming a diet high in sugar, refined carbohydrates, and unhealthy fats may disrupt your body's insulin balance, possibly contributing to thinning hair. Overconsumption of vitamin A is also associated with hair loss.



  • High Sugar Foods: Foods with excessive sugar can cause an insulin imbalance in your body, potentially leading to hair thinning.
  • Refined Carbohydrates: Similar to high-sugar foods, refined carbs can also disrupt your insulin levels and contribute to hair thinning.
  • Unhealthy Fats: Saturated and trans fats not only impact your overall health but can also negatively affect your hair health.
  • Excessive Vitamin A: While Vitamin A is essential for healthy hair, overconsumption has been linked to hair loss.
  • Fast Food: Usually, fast food contains an excess of unhealthy fats and sugars, which could disrupt the balance of insulin levels in your body.
  • Alcohol: The consumption of alcohol can cause dehydration in your body, resulting in hair that's dry and prone to breakage.
  • Caffeine: Excessive intake of caffeine can lead to dehydration, which can damage your hair.


To maintain healthy and vibrant hair, it's essential to pay attention to your dietary habits. Avoiding certain foods and ingredients that can harm your hair health is as important as including those that boost it. Remember, your hair reflects your overall health, so make sure to nourish it from the inside out.

Like many of my patients, I struggled with hair loss for years. My hair began thinning in high school, and by my 20s, my confidence was at an all-time low. I tried every vitamin and hair loss remedy, and spent countless hours trying to mask my baldness, feeling self-conscious in both personal and professional settings. It wasn’t until my late 30s that I finally took action. After undergoing a successful hair restoration procedure, my life changed dramatically. Within 8 to 12 months, my hair grew back, and with it, my confidence soared. I looked 10 years younger, and I no longer had to rely on time-consuming styling tricks. People treated me differently, and I felt like the best version of myself. That transformation led me to make a major career shift—from a successful Trauma and Cancer Surgeon to a full-time hair restoration specialist. I was double board-certified by the American Board of Surgery in Trauma Surgery & Critical Care Surgery and thriving in my field, but my personal experience with hair loss gave me a new mission. I knew firsthand the emotional toll it takes, and I wanted to help others regain not just their hair, but their self-esteem and quality of life. I initially worked for a large corporate hair restoration group but quickly realized that the best results come from a physician-led practice—where the doctor is personally invested in every patient’s success. That’s why I founded Yates Hair Science Group. We specialize in advanced FUE hair restoration and cutting-edge biologic treatments to achieve the best possible results. Unlike many clinics, I personally perform every procedure—never delegating to technicians or nurses—because hair restoration is both a science and an art. Every patient I treat, whether through surgical or non-surgical solutions, I connect with on a personal level—because I’ve lived their journey. I believe a specialty as life-changing as hair restoration should never be driven by corporate interests focused solely on profit. If you're struggling with hair loss, I understand what you’re going through because I’ve been there myself. Let’s work together to find the right solution for you. Schedule a consultation today and take the first step toward restoring your hair—and your confidence.

The public should be aware of an alarming issue within the Chicago area hair restoration industry: unlicensed individuals posing as licensed physicians and performing medical procedures. This deceptive practice jeopardizes patient safety and erodes trust in qualified medical professionals. Recent reports have uncovered that patients seeking treatment at the International Hair Institute (IHI) were led to believe that their procedures were performed by Jing Liu, MD, CEO of the clinic. Upon investigation, it became evident that while Ms. Liu obtained a medical degree in China, she has neither undergone the necessary training nor acquired licensure to practice medicine in the United States. Previously employed as a lab assistant at Northwestern Hospital, she is not listed with the Illinois Department of Financial and Professional Regulation (IDFPR) as a licensed physician. Despite this, Ms. Liu is reportedly presenting herself as an American-licensed physician and performing hair restoration surgeries at IHI. In response to inquiries from discerning patients, Ms. Liu has allegedly claimed the clinic is overseen by a licensed internist, Dr. Wang, who has no known expertise in hair restoration and may not even be present onsite. This deceptive behavior not only endangers patients but also undermines the integrity of the medical profession. Unlike hospital settings—where physicians undergo rigorous vetting and credential verification to ensure they can practice their specialty safely, competently, and ethically—some hair restoration clinics operate with little to no oversight. Many patients remain unaware of the complexity and skill required for hair transplant surgery. As a former board-certified general, cancer, and trauma surgeon, I can attest that hair transplant surgery demands both mental and physical dexterity, as well as extensive training and experience, to achieve safe and excellent outcomes. Illinois law mandates that only a licensed physician may perform procedures involving incisions in the skin. In hair transplant surgery, these include FUT (follicular unit transplantation) linear scalp incisions, FUE (follicular unit extraction) punch graft harvesting, and recipient site creation for follicular grafts. Despite these clear legal guidelines, it appears that many clinics delegate these critical tasks to unqualified medical assistants or non-physician staff, putting patients at unnecessary risk. Such practices insult physicians who have undergone years of rigorous training in accredited medical schools, residency programs, and fellowships. The lack of enforced regulations in the hair restoration industry has enabled this brazen disregard for medical standards to persist. Without proper oversight and accountability, the situation will likely worsen, leaving more patients vulnerable to substandard and unsafe care. This is an urgent call for increased regulatory enforcement and public awareness to protect patients and restore trust in the medical profession.

It’s a well-known fact that nearly 60 million Americans experience hair loss at some point in their lives. Among the many options for restoring the luster of one’s hair, hair transplantation is widely regarded as offering the most enduring results. Recent data from the International Society of Hair Restoration Surgery (ISHRS) shows a clear uptick in the number of hair transplants, with procedures increasing by 20% or more annually. This surge in demand has opened the floodgates for a multitude of less-than-qualified physicians and non-physicians who claim to be experts in the field. Unlike traditional medicine, where doctors must graduate from an accredited medical school and undergo rigorous vetting by committees and other professionals to practice in hospitals or specialize in their fields, there are no comparable standards of care for hair transplants. This lack of regulation makes it difficult for patients to determine who is truly qualified to perform such procedures. Although licensed healthcare providers are held to strict medical and ethical standards, the absence of oversight in hair transplant practices has led to alarming trends. Some physicians are completing weekend courses and immediately setting up fully operational clinics, with little to no hands-on experience. Hair transplant centers are also being opened by businesspeople with no medical expertise, who hire the cheapest available physicians or technicians to perform the procedures. To make matters worse, some clinics intentionally obfuscate the qualifications of their staff—such as individuals with doctorates in unrelated fields who claim to be medical doctors—and others employ foreign-trained doctors who are not licensed to practice in the U.S. These professionals often misrepresent their credentials, degrees, and skill sets. I was recently made aware of a physician, Vinay Rawlani, who allegedly held a staff position at Northwestern University, a prestigious hospital in Chicago where I proudly attended medical school. Many patients who have visited my office mentioned that they had also consulted with him, and he claimed to be a staff member at Northwestern, with an office there. Upon further investigation, I discovered that his medical license had been revoked in 2017 and only reinstated in 2020, which would render it impossible for him to be an expert in hair transplant surgery. Rawlani was also charged with felony theft of nearly $200,000 worth of equipment from the hospital. Although the stolen property was found in his home, Rawlani pleaded not guilty to the charges. This information is a matter of public record. It is absurd that someone who has stolen from a hospital and profited from that theft is now masquerading as a faculty member at the very institution he victimized. I am shocked that Northwestern has allowed him to rent office space within the institution from which he stole. Rawlani’s deception has been so successful that he is now recognized as a medical director at other hair transplant clinics. I personally know convicted felons who are denied the privilege to vote. By no means, however, is Rawlani the only one pretending to be an expert in this field. To protect yourself, follow these steps when considering a hair transplant: First, verify the provider’s credentials to ensure they are licensed and certified by a recognized medical board. Research the clinic by looking for reviews and before-and-after videos (which can’t be manipulated like photos) and confirming the facility’s accreditation. Don’t hesitate to ask questions about the provider’s experience, techniques, and safety protocols. A hair transplant is an investment in your appearance and confidence. Cutting corners by choosing an unlicensed provider can lead to devastating health complications, poor results, and significant financial and emotional costs. When it comes to your health and well-being, the best option is always the one that prioritizes safety and expertise. Make informed choices, and you’ll not only protect yourself but also achieve the lasting, natural results you deserve.
