Each day, around 700 people are diagnosed with diabetes.

It affects around 4.9 million people in the UK, while approximately 850,000 of those living with it have yet to be diagnosed.

Diabetes is a chronic condition that has several effects on the body, including diabetes hair loss.

This can be difficult for anyone to experience at any age, particularly if you feel your hair is one of your key defining traits.

But why does diabetes cause hair to fall out, and will hair loss from diabetes grow back?

In this post, we’ll cover the common types of diabetes, how they can cause hair loss, and what treatment options are available.

What is diabetes?

Diabetes affects blood sugar levels

Diabetes is a medical condition that leaves the body unable to produce a healthy amount of insulin, a natural hormone created by the pancreas.

The body lacks the insulin required to move the glucose, or the insulin produced is unable to perform its function.

Diabetes hair loss can be caused by both types 1 and type 2

Diabetes hair loss

Diabetes can cause hair thinning and hair loss in some people as it can have the following effects on the growth cycle of the hair:

  • impairing hair growth
  • causing more hair to grow than normal
  • stopping new hair from forming

Several different factors may cause a person with diabetes to lose hair, but the most common causes include those below.

Diabetes can cause hair loss


Hyperglycemia (high blood sugar) happens when sugar isn’t taken into cells for energy and instead remains in the blood flow.

This may occur as a result of a lack of insulin, insulin resistance, or both. The excess sugar can lead to damaged blood vessels if the issue persists for a prolonged period.

This can also restrict blood flow below the knees, which may damage hair follicles on the leg.

The decreased blood flow also leads to less oxygen and nutrients for the hair follicles, and as a result, the normal growth cycle of hair gets disrupted.

Improper blood sugar control can cause poor circulation and vascular impairment.

Hyperglycemia may also cause hair thinning, fragile hair, and decreased hair growth speed.

Insulin resistance can result in microvascular impairment, which has a role in the pathophysiology of androgenetic alopecia.

A 2019 study found that black women are at a higher risk of central scalp hair loss due to type 2 diabetes.

The research concluded that black women with type 2 diabetes hair loss should be monitored closely in order to identify the issue and administer the appropriate treatment in time.

Thyroid Issues

Thyroid disease may cause hair shedding

People with diabetes should have their thyroid levels checked at least once per year. Thyroid disease is especially common in patients with type 1 diabetes hair loss.

Hypo- or hyperthyroid disease can lead to significant hair thinning.

Alopecia Areata

People with type 1 diabetes have a higher likelihood of developing other autoimmune disorders.

The most common one is alopecia areata, which occurs due to the immune system attacking a person’s own hair follicles. This can lead to patchy hair loss.

Alopecia areata can affect the entire body, leading to thinning hair on the scalp, eyebrows, eyelashes, or other areas of the body.

Hormones and stress

Diabetes can put a great deal of stress, both physical and emotional, on a person’s body. Persistent stress can cause hormone fluctuations that can affect hair growth.

Is hair loss from diabetes reversible?

In most cases, diabetes hair loss isn’t permanent. Diabetes management can be achieved by multiple ways, although treatment can differ for males and females.

Many people can slow or stop diabetes hair loss. One of the most effective ways is simply controlling the high blood sugar level and limiting emotional and physical stress.

Blood sugar management involves:

  • Regularly monitoring a person’s blood sugar levels
  • Taking all medications as instructed
  • Having a balanced diet
  • Exercising on a regular basis

Some of the best ways to manage stress are:

  • Seeking support from friends and family
  • Going to counseling
  • Practicing meditation, yoga, or breathing techniques

How to treat diabetes hair loss – 7 treatment options

You should keep in mind that there is no universal treatment that works for everyone.

Treatment options will largely depend on the cause of hair loss and the type of hair loss you’re experiencing.

Male and female pattern hair loss is treated differently than alopecia areata for example. However, in most cases, hair growth returns to normal once the intervention is started.

1. Managing blood sugar levels

As we’ve already discussed elevated blood sugar levels can damage blood vessels, cause vascular disruption, and hormonal imbalances as well as lead to hair loss.

Therefore, maintaining your blood sugar levels within a normal range can prevent you from developing the signs of diabetes hair loss.

The normal range of blood sugar will depend on a person’s age, whether they experience hypoglycemia regularly, and how long they’ve had diabetes.

Generally speaking, blood sugars should be 80-130 mg/dL after not eating for at least 8 hours, and below 180 mg/dL two hours after eating.

However, these levels should be individualized with the help of a healthcare team.

2. Medication

Some medications are known to treat hair loss and lead to more hair growth. The type of medicine you’re prescribed will depend on your age, your hair loss type, and the risks or side effects.

3. Corticosteroid creams or injections

Injections are primarily administered for adults, and they’re usually not recommended for children.

Creams may be applied to the areas affected by hair loss in both adults and children. Injections usually make hair regrow for adults, while creams tend to be more effective for children.

4. Minoxidil (Rogaine)

Rogaine is a solution for hair loss

Minoxidil is a common form of treatment for androgenic alopecia in both men and women. It stimulates growth by increasing the blood supply to each hair follicle.

It is available in topical or cream forms, and it’s supposed to be applied directly to the scalp on a daily basis.

However, the drug has several side effects, and you have to take minoxidil indefinitely if you want to maintain the results.

Regaine for Men Extra Strength Foam costs £35.95 on Amazon.

5. Anthralin

Another topical medication, which is often used in tandem with minoxidil. It works by slowing down the growth of skin cells.

Anthralin may cause skin irritation, skin soreness, and in more extreme cases, further hair loss.

6. Finasteride (Propecia)

Finasteride may treat diabetes hair loss

The American FDA approved finasteride for use against male hair loss. The drug is used in both the treatment of enlarged prostates and male pattern baldness.

Several peer-reviewed studies have found that finasteride can lead to increased hair growth by decreasing the amount of DHT within the body.

It comes in the form of a tablet, that you’re supposed to take every day for it to take effect.

However, the drug may cause erectile dysfunction, decreased libido, ejaculation disorder, and breast enlargement.

Women shouldn’t take finasteride, as it can also lead to birth defects and decreased childbearing potential.

Similar to minoxidil, you must take finasteride indefinitely if you want to maintain the drug’s results.

28 tablets of generic finasteride cost £12.20 on Doctorfox.

7. Hair transplantation

A hair transplant surgery may be an option if diabetes has disrupted your hair growth cycle.

Great care is critical, though, to ensure people affected by diabetes hair thinning remain safe and comfortable during hair transplants. Blood sugar levels must be monitored closely.

Other effects of diabetes on the body

The symptoms of diabetes affect the body in several different ways, particularly if a person is unable to control their high blood sugar levels. Some of the most common issues associated with diabetes include:

  • Higher risk of stroke
  • Increased risk of peripheral arterial disease
  • Increased risk of heart disease
  • Damage to the nerves
  • Dry mouth
  • Dry skin
  • Having a higher risk of infection


Diabetes is a chronic condition that can have a wide range of effects on a person’s body. In some people, diabetes can cause hair thinning or hair loss.

The primary causes of hair loss in people with diabetes are uncontrolled blood sugar levels, emotional and physical stress, and hormone imbalances.

Using medications and lifestyle interventions to get blood sugar levels under control may help reverse or slow down the effects of hair loss.

Some medications are also available for the treatment of hair loss, although their effects may be short-lived.


Does diabetes cause your hair to fall out?

In some people, diabetes can cause hair to fall out. The primary causes of hair loss in people with diabetes are uncontrolled blood sugar levels, emotional and physical stress, and hormone imbalances.

How to stop hair loss from diabetes?

When your blood vessels get damaged, your body can’t properly transport oxygen and nutrients to your hair follicles, which can damage the hair growth cycle. The best way to avoid hair loss due to high blood sugar is to focus on eating a diet made up of foods with a low glycemic index.

Does diabetes cause hair loss on legs?

Diabetes can also cause hair loss on the legs. Over time, diabetes-related damage to the blood vessels can result in peripheral artery disease (PAD). In PAD, a fatty deposit called plaque builds up in the blood vessels inside the legs. This interferes with blood flow and, consequently, hair growth
