Does Diabetes Cause Hair Loss?

Diabetes can potentially contribute to hair loss, although it is not a direct cause of this condition. Yet, complications related to diabetes may affect many organs in the body and one of such complications may be hair loss.

Diabetes is a metabolic syndrome characterized by chronic hyperglycemia. Blood sugar levels rise above the norm and this condition continues for a long time. Elevated blood glucose levels affect all the organs. As a result, it may also lead to the weakening of the hair, the hair growth process, and excessive hair loss from diabetes.

Here are some key notes from the article on hair loss and diabetes:

  • NOT EVERYONE WITH DIABETES WILL EXPERIENCE HAIR LOSS.
  • BOTH TYPES OF DIABETES MAY CAUSE HAIR LOSS, BUT THE MECHANISMS BEHIND IT ARE DIFFERENT.
  • WHEN DIABETES IS TREATED EFFECTIVELY, YOUR HAIR HAS THE POTENTIAL TO GROW BACK.
  • DIET, EXERCISE, STRESS MANAGEMENT, AND MONITORING YOUR HEALTH ARE THE BEST WAYS TO KEEP YOUR DIABETES HAIR LOSS UNDER CONTROL.

HEALTHCARE HINT💡

A hemoglobin level below 7% will improve your health and prevent additional complications from diabetes, which include hair loss.

Can Diabetes Cause Hair Loss?

Hair loss can be a symptom of type 1 and type 2 diabetes. Yet, the mechanisms behind it may be different for each type of diabetes.

Can Type 1 Diabetes Cause Hair Loss?

In type 1 diabetes, hair loss can start because of uncontrolled high blood sugar levels and the resulting damage to blood vessels.

Poor circulation may affect the hair follicles, leading to hair loss or diabetes hair thinning.

Can High Blood Sugar Cause Hair Loss?

Yes, it can. High blood sugar and hair loss may be related, but the connection is indirect and complex. Managing blood sugar fluctuations through medications, diet, and lifestyle changes can help you control your hair loss.

Diabetes mellitus is a group of metabolic disorders due to high blood sugar levels.

Can Type 2 Diabetes Cause Hair Loss?

People with type 2 diabetes can experience hair loss too, and it may happen due to insulin resistance. When the body becomes resistant to insulin, it can result in hormonal imbalances. One of them is elevated levels of androgens, which can contribute to hair loss, especially in women.

Can Insulin Cause Hair Loss?

Insulin itself does not cause hair loss directly. Yet, there may be a connection between insulin and hair loss indirectly, through diabetes.

If you suffer from uncontrolled diabetes or insulin resistance, you can experience hair-related issues, like insulin hair loss.

Insulin is a hormone made by the pancreas that helps control blood sugar levels. Insulin resistance occurs when the body’s cells don’t respond well to insulin. As a result, the body produces more insulin to make up for this lack of response.

High levels of insulin and insulin resistance can cause hormonal imbalances that may lead to hair loss.

Can Prediabates Cause Hair Loss?

Prediabetes itself does not directly cause hair loss. Yet, prediabetes and hair loss can be indirectly connected.

Prediabetes is often associated with insulin resistance and abnormal hormonal levels. Hormonal imbalances, such as elevated levels of androgens, can lead to conditions such as androgenetic alopecia (male or female pattern baldness). They may result in hair loss.

Insufficient intake of nutrients can lead to hair thinning and hair loss. Also, due to hyperglycemia, decreased blood flow to the scalp can affect hair follicles’ health and growth.

Is Sugar Bad For Your Hair?

Yes, it is. Consuming too much sugar can have a negative effect on your overall health. This, as a result, may lead to your hair’s poor condition too.

  • CONSUMING TOO MUCH SUGAR CAN LEAD TO NEGLECTING NUTRIENTS IMPORTANT FOR YOUR HAIR’S HEALTH.
  • CHRONIC INFLAMMATION MAY INTERFERE WITH THE NORMAL HAIR GROWTH CYCLE.
  • EXCESSIVE CONSUMPTION OF SUGAR CAN LEAD TO INSULIN RESISTANCE AND HORMONAL IMBALANCES.
  • GLYCATION CAN DAMAGE THE COLLAGEN AND ELASTIN FIBERS IN YOUR HAIR.

Why Does Diabetes Cause Hair Loss?

Remember that diabetes itself does not directly cause hair loss. Yet, there are several ways in which it may indirectly lead to your hair problems. So, why may diabetes cause hair loss?

HIGH BLOOD SUGAR LEVELS: PROBLEMS WITH CIRCULATION AND DELIVERY OF NUTRIENTS AND OXYGEN TO HAIR FOLLICLES.

HORMONAL FLUCTUATIONS: BLOOD SUGAR CHANGES MAY AFFECT HORMONE LEVELS AND CONTRIBUTE TO DIABETIC HAIR LOSS.

NUTRITIONAL DEFICIENCIES: BIOTIN, IRON, AND ZINC DEFICIENCIES.

AUTOIMMUNE DISORDERS: DIABETES CAN LEAD TO DIABETIC ALOPECIA.

CHRONIC INFLAMMATION: MAY AFFECT HAIR FOLLICLES AND HAIR GROWTH.

MEDICATIONS: POTENTIAL SIDE EFFECTS OF DIABETES DRUGS.

OTHER HEALTH ISSUES: DIABETES CAN LEAD TO THYROID DYSFUNCTION, WHICH ARE ASSOCIATED WITH HAIR LOSS.

You need to know that not everyone with diabetes will experience hair loss. Also, the severity of hair loss can vary from person to person.

What Does The Body Lack That Causes Hair Loss?

Here is a list of main nutrients that, when lacking in the body, may lead to hair loss:

  • PROTEIN: HAIR LOSS CAUSED BY KERATIN DEFICIENCY.
  • AMINO ACIDS: CYSTEINE AND METHIONINE AFFECT KERATIN FORMATION.
  • SEVERAL VITAMINS: ESPECIALLY VITAMIN A, D, AND B GROUP VITAMINS.
  • ZINC: DEFICIENCY MAY DISRUPT THE HAIR GROWTH CYCLE.
  • OMEGA-3 FATTY ACIDS: LOW LEVELS CAN CONTRIBUTE TO HAIR PROBLEMS.
  • SELENIUM: DEFICIENCY CAN LEAD TO HAIR THINNING.
  • IRON: LOW LEVELS CAN LEAD TO ANEMIA.


To understand any potential deficiencies you need to take appropriate tests. Your doctor will then recommend dietary changes or necessary supplements.

⚠️ To understand any potential deficiencies you need to take appropriate tests. Your doctor will then recommend dietary changes or necessary supplements.

Does Too Much Sugar Lead To Hair Loss?

Sugar consumption can be related to hair loss indirectly if exceeded vastly in your diet. First of all, consuming too much sugar can lead to nutritional imbalances.

High sugar intake can contribute to insulin resistance, which may result in hormonal imbalances.

Sugar can also increase inflammation in the body. Chronic inflammation may interfere with hair follicle health, leading to hair loss.

What Are The Signs Of Diabetes Hair Loss?

Remember that the signs of diabetes hair loss may be very similar to different types of hair loss. Yet, you may have a closer look at some signs and considerations that can be related to hair loss in diabetes.

  • DRY AND BRITTLE HAIR
  • SLOWER HAIR GROWTH
  • GRADUAL THINNING OF THE HAIR, ESPECIALLY ON THE SCALP
  • BALD PATCHES AS A RESULT OF AUTOIMMUNE CONDITIONS

How Do You Prevent Hair Loss From Diabetes?

Here are some steps you can take to help prevent hair loss if you have diabetes:

  • MONITOR YOUR BLOOD SUGAR LEVELS REGULARLY
  • KEEP A HEALTHY LIFESTYLE WITH A BALANCED DIET
  • STRESS MANAGEMENT WILL HELP YOU OUT
  • TAKE CARE OF YOUR SCALP, USE GENTLE HAIR PRODUCTS
  • AVOID TIGHT HAIRSTYLES


Proper hair care practices are crucial for minimizing diabetes hair loss. Remember that your individual experiences with diabetes and hair loss will be unique and may vary from the experiences of others.

Will Hair Loss From Diabetes Grow Back?

When badly managed diabetes is treated effectively, your hair has the potential to grow back.

  • MAINTAINING STABLE BLOOD SUGAR LEVELS
  • IMPLEMENTING AN ACTIVE LIFESTYLE AND HEALTHY DIET
  • CONSIDERING HAIR REGROWTH TREATMENTS


⚠️ The relationship between diabetes is related to multiple factors. They include hormonal imbalances, circulation issues, or inflammation. You need a consultation with a physician regarding your hair loss and may consider some hair regrowth treatments.

What Works Best For Diabetes Hair Loss?

The more uncontrolled diabetes, the more severe hair loss. If you want to prevent or stop hair loss, you need to keep your diabetes under control. The more normal the blood sugar concentration, the lower the risk of damage to the microcirculation. How can you obtain that?

  • LIFESTYLE CHANGES
  • HAIR LOSS MEDICATIONS
  • SUPPLEMENT INTAKE
  • HAIR LOSS THERAPY

Lifestyle Changes

A healthy lifestyle means a balanced diet, regular exercise, and stress management. High blood sugar levels can contribute to oxidative stress, which may harm hair follicles.

You need to focus on whole foods, fruits, vegetables, lean proteins, and whole grains. Regular physical activities can improve insulin sensitivity and help with blood sugar control.

⚠️ Regular visits are important for monitoring your diabetes. Managing diabetes (blood pressure and cholesterol levels) is important to reduce the risk of diabetes complications. It is also crucial to take medications prescribed by your doctor.

Hair Loss Medications

Your doctor can recommend medications for hair regrowth. One of them is Minoxidil (Rogaine). It is an over-the-counter drug. Minoxidil is a topical solution that stimulates hair growth and slows down hair loss.

The other drug is Finasteride (Propecia), which needs a prescription from a doctor. It works by blocking the conversion of testosterone to dihydrotestosterone (DHT). DHT is a hormone that can shrink hair follicles and cause hair loss.

⚠️ It is not suggested women to use Finasteride. 

Supplement Intake

Biotin, or vitamin B7 or H, is a water-soluble B vitamin. It is often a supplement for hair, skin, and nail health.

Biotin deficiency can lead to hair loss, but it is very rare. For people with diabetes, taking biotin supplements will most probably not be a risk, but there are a few important factors to consider.

Biotin may interfere with certain blood glucose tests, leading to falsely high or low results. Also biotin, like any other supplement, can potentially interact with certain medications for diabetes. It is always better to get nutrients like biotin from a nutritious, balanced diet.

Hair Loss Therapy

Platelet-rich plasma hair loss therapy (PRP) works by injecting a concentrated solution of platelets from your own blood into the scalp. Poor blood circulation associated with diabetes can limit the delivery of nutrients to your hair follicles. 

Platelets contain growth factors that can stimulate hair follicles, helping with hair growth. They also strengthen existing hair. A low-laser therapy, on the other hand, irradiates photons into scalp tissues. These photons are then absorbed by weak cells and help in your hair growth.

Remember that PRP or laser therapy might help improve hair health and growth, but it will not directly solve the underlying causes of hair loss related to diabetes. It may be a complementary treatment, but not the solution to the problem.

Hair Transplantation

Hair transplantation is the final treatment option.

Even though getting a hair transplantation is a final option, it is among the treatments that can be useful for hair loss.

The underlying problems should be addressed. If you manage your diabetes properly, yet still want to get fuller hair in a short amount of time, you may try hair loss transplants after discussing it with a doctor.

What Diabetes Medications Cause Hair Loss?

Hair loss may be a side effect of certain medications for diabetes. If you worry that a diabetes medication affects your scalp health, hair health, and hair loss, consult with your doctor. You may need to change your treatment. 

  • METFORMIN
  • THIAZOLIDINEDIONES (TZDs)
  • SULFONYLUREAS (GLYBURIDE AND GLIPIZIDE)
  • SODIUM-GLUCOSE COTRANSPORTER-2 (SGLT2) INHIBITORS


⚠️ Everyone reacts to drugs differently. The most important thing is to consult your doctor if you experience hair loss as a result of medication side effects.

Does Metformin Cause Hair Loss?

Metformin is a drug prescribed for type 2 diabetes. Hair loss is not a common side effect of metformin use. Yet, some patients report hair-related issues while using this medication.

Metformin can affect the absorption of vitamin B12, which is important for hair health. Some people may also experience hormonal changes as a result of improved blood sugar control with metformin. These changes could potentially impact diabetes and hair growth.
