Can Diabetes Cause Hair Loss? Tips for Healthy Hair Management

The answer to the question "Can diabetes cause hair loss?" is yes there's a connection. Hair loss is one of the lesser-known symptoms that can arise in individuals with diabetes. It's not just about high blood sugar levels; the link between diabetes and hair loss is multifaceted, involving aspects like hormonal imbalances and poor circulation.

Whether you're dealing with type 1 or type 2 diabetes, your condition could be playing a role in hair thinning or loss. Alopecia areata, an autoimmune disorder that often accompanies type 1 diabetes, specifically targets hair follicles. But don't fret—understanding the relationship between diabetes and hair loss is the first step in managing and potentially reversing the condition.

Can Diabetes Cause Hair Loss

Signs That Diabetes May Be Causing Your Hair Loss

When you're experiencing hair loss, it's essential to consider various factors, and diabetes might be one of them. High blood sugar levels (hyperglycemia) due to diabetes could be the culprit behind your thinning hair. Elevated blood sugar can cause damage to your blood vessels over time, and poor circulation may lead to deprived hair follicles that are unable to sustain normal hair growth.

Keep an eye out for these signs indicating that diabetes could be impacting your hair:

  • Slow hair growth and the development of thinner strands may be your first observable sign.
  • You may notice more hair than usual falling out during brushing or washing.
  • The appearance of bald patches on the scalp could potentially be linked to alopecia areata, an autoimmune condition often accompanying type 1 diabetes.

Remember, various factors influence hair health, and nutrient deficiencies or stress can also lead to hair loss. However, if you find that your hair loss aligns with symptoms of hyperglycemia—like extreme thirst, frequent urination, or blurred vision—it's a strong indication that diabetes may be connected to the issue.

Prediabetes can also have hair loss as a symptom, and in this case, preventive measures can be crucial. Monitoring your blood sugar levels is key in managing the state of your hair. If your glucose readings are consistently higher than usual, it's time to consult with your healthcare provider to assess the effects of your blood sugar regulation on hair growth.

While diabetes management can be complex, recognizing these signs early could help you address hair loss more effectively and maintain healthier hair despite the challenges that diabetes presents.

How Diabetes Affects Hair Health

When you have diabetes, your body may experience chronic, low-grade inflammation. This type of inflammation can impair the normal hair cycle, disrupting growth and leading to hair loss. Your hair has a defined growth cycle that includes phases of growing, resting, and shedding. Diabetes-related inflammation can cause this cycle to accelerate or stall. In particular, the inflammation can damage your hair follicles, where your hair starts its growth. When these follicles are inflamed, they may not produce hair as efficiently, leading to the excessive shedding you might notice.

A pivotal aspect to consider is the effect of the immune system as well. When your body is dealing with long-term high blood sugar levels, the immune response can sometimes go into overdrive, which could escalate the inflammation around your hair follicles. And when inflammation is chronic, it doesn't just stop with hair loss—you could see additional health issues like skin problems and a higher sensitivity to infection, which could further exacerbate hair-related concerns.

Understanding the Connection

Diving deeper, it's essential to understand how exactly diabetes can alter hair health. First, blood sugar levels play a significant role. In the case of diabetes, fluctuating or consistently high blood sugar levels contribute to the problem. High blood sugar can interrupt the supply of nutrients and oxygen to your hair follicles, essentially starving the hair of what it needs to grow healthily. Additionally, poor blood circulation often associated with diabetes can lead to weaker hair that's more prone to breaking.

"If your gut is not able to help you digest and break down food, assimilate it and then eliminate the waste products, you're in trouble."

Another crucial factor is diabetes-related hormonal changes. With diabetes, your body's endocrine balance is affected, which can off-kilter the typical hair growth cycle. For instance, you might find you're losing hair at a faster rate than it can regrow, or new hair could come in thinner or weaker than before.

Furthermore, since diabetes can lead to hypothyroidism, a condition that influences your metabolism, this too can impact your hair's health. Hypothyroidism often results in having a dry and brittle hair texture, which contributes to hair loss. It's a chain reaction—your diabetes impacts your thyroid, which then affects your hair.

Keep in mind that the level of blood sugar control can make a significant difference. Optimal management may help slow down the hair loss process. It's crucial to monitor your diabetes closely and maintain a balanced blood sugar level, thus helping mitigate hair loss.

Other Factors Contributing to Hair Loss in Diabetes

Alongside inflammation, multiple factors contribute to hair loss in individuals with diabetes. Understanding these factors can help you take proactive steps toward maintaining hair health.

Poor Blood Circulation

Poor blood circulation is notoriously problematic for diabetics, as it can lead to far-reaching effects on overall health, including hair loss. Hair follicles require a steady supply of blood to maintain growth and health. However, with the impairment caused by high blood sugar levels, your scalp and hair follicles receive less oxygen and vital nutrients they need to thrive. The result is a slower hair growth cycle, leading to brittle hair and eventual shedding. To combat poor circulation, integrating frequent exercise and a diet rich in essential nutrients can make a substantial difference over time.

Diabetes Medication

Ironically, while medication may be necessary to control diabetes, certain diabetes medications could negatively impact hair health. For example, Metformin, a frontline medication for type 2 diabetes, can cause vitamin B12 deficiencies, inadvertently affecting hair growth. Be vigilant about potential side effects of your medications especially if you notice changes in hair density or growth patterns; there might be alternative treatments that come with fewer hair-related side effects.

Nutritional Deficiencies

Individuals with diabetes must closely monitor their nutritional intake to manage blood sugar levels. Sometimes, the dietary restrictions required to control diabetes can lead to nutritional deficiencies. A lack of adequate levels of iron, zinc, and proteins can impair hair growth and strength. Consider a nutritional supplement for hair health, to help restore these vital nutrients and promote healthier hair.


"If you're constantly stressing, your blood sugar's probably climbing with it, and that's one way that people can develop type 2 diabetes and pre-diabetes."

Dr Beverly Yates

Stress can exacerbate hair loss through its effects on the body's hormonal balance. It can extend hair follicles' resting phase, reducing new hair growth and making existing hair feel less full and vibrant. Stress management techniques like regular exercise, mindfulness, and sufficient sleep are crucial for mitigating these effects and encouraging a steady hair growth cycle.

Autoimmune Disorders

For those living with diabetes, especially type 1, there's an increased risk of autoimmune disorders such as alopecia areata. This condition causes the body's immune system to attack hair follicles, resulting in sudden hair loss, typically in patches. Since autoimmune conditions are more prevalent among diabetics, it's essential to stay alert to symptoms and seek advice promptly if they arise.

Hormonal Imbalance

Lastly, hormonal imbalance is a significant contributor to hair loss in people with diabetes. Insulin resistance, a characteristic of type 2 diabetes, and thyroid disorders, often associated with diabetes, can lead to fluctuations in androgen and estrogen levels. These hormonal changes not only impact blood sugar control but also affect the hair growth cycle, potentially leading to hair thinning and loss. Monitoring hormone levels is key in managing this aspect of diabetes-inflicted hair loss.

Managing Hair Loss in Diabetes

Controlling Blood Sugar Levels

Your first line of defense against hair loss when managing diabetes is meticulous blood sugar control. Consistently high blood sugar levels can damage the small blood vessels that nourish the hair follicles, impeding normal hair growth. Here's what you can do:

  • Monitor your blood sugar levels regularly to keep them within a target range.
  • If on diabetes medication, take as prescribed; do not alter unless you contact your prescriber first if you notice side effects related to hair loss, since they might adjust your regimen to alleviate the symptoms.

Improving blood sugar management could lead to a noticeable reduction in hair loss, stimulating the regrowth of your hair. Remember, you're not just managing your diabetes; you're also proactively taking steps to preserve your hair's vitality.

Maintaining a Healthy Lifestyle

Living with diabetes requires a holistic approach for maintaining overall well-being, including the health of your hair. Stress, both physical and emotional, can exacerbate hair loss, so finding ways to manage it is essential. Integrate these healthy lifestyle practices to create a favorable environment for hair preservation:

  • Opt for balanced food choices that support both your blood sugar levels and hair's nutritional needs.
  • Regular physical activity is indispensable; it aids in stress reduction and helps to stabilize glucose levels.
  • Consider techniques such as yoga, meditation, or deep-breathing exercises for effective stress management.
  • Ensure you're getting adequate sleep; quality rest can have a significant impact on stress and hormonal balance.
  • Be gentle with your hair; avoid harsh hair treatments and consider using healthy hair care products to minimize further damage.

By adopting these strategies into your daily routine, you're not only looking after your diabetes management but also creating a sustainable environment for healthy hair growth. The integration of blood glucose control and a robust lifestyle approach offers a comprehensive path to reducing the chances of hair loss associated with diabetes.


Understanding that diabetes can indeed impact your hair's health is crucial. Taking charge of your blood sugar levels is a significant step towards protecting the vitality of your hair follicles. Remember to couple this with a lifestyle that supports overall wellness—balanced nutrition, consistent exercise, and effective stress reduction routines will help your hair stay healthy.
