Hair loss can be a distressing condition, but it’s important to understand the possible causes of hair loss. One potential cause that people may have heard about is insulin. But does insulin actually lead to hair loss? In this article, we’ll explore what research has revealed about the relationship between insulin and hair loss.

We’ll look at evidence from both observational studies and clinical trials, as well as discuss other factors that could potentially play a role in causing or preventing hair loss. We’ll also provide some tips for those who are concerned about their own risk of experiencing hair loss due to high levels of insulin. By the end of this article, you will have a better understanding of how insulin affects your hair health.

Evidence From Observational Studies

The question of whether insulin causes hair loss has been asked by many. It is an intriguing subject to explore given the significant role that insulin plays in the body’s processes, such as regulating blood sugar levels. But does it also affect our outward appearance? To answer this, let us examine what evidence from observational studies reveals about this issue.

One study conducted on non-diabetic men found that higher serum concentrations of insulin were associated with increased balding scores and further progression of male pattern baldness over a 10 year period. A more recent study compared self-reported hair loss among people with type 1 diabetes versus those without diabetes. Results showed that participants who had type 1 diabetes were twice as likely to report experiencing hair loss than those without the condition. This suggests that there may be some sort of connection between insulin and hair loss for people living with diabetes at least.

In another study looking at women’s health, researchers attempted to determine if high levels of fasting plasma glucose (FPG) – which can indicate high levels of circulating insulin – was linked to alopecia areata (patchy hair loss). They found no association between FPG or other markers related to glucose metabolism and alopecia areata occurrence during follow up periods ranging from 5 years to 11 years. This indicates that while there appears to be a link between insulin and male pattern baldness, hair loss due to other forms like alopecia may not necessarily be affected by changes in one’s insulin levels.

Overall, these findings suggest that although elevated serum concentrations of insulin have been strongly linked with increased rates of male pattern baldness, further research is needed when examining the relationship between various types of hair loss and changes in one’s glucose metabolism indicators such as FPG or circulating insulin levels. With this in mind, we now turn our attention towards exploring what clinical trials tell us about this matter…

Evidence From Clinical Trials

The evidence from clinical trials examining the connection between insulin and hair loss is inconclusive. Some studies have suggested that people with diabetes may experience more hair thinning or shedding than those without, but further research needs to be conducted before a definitive link can be established.

One study found that when women with type 2 diabetes were given oral hypoglycemic agents, their rate of hair shedding decreased over time while they experienced significant improvements in blood sugar levels. However, it was not clear whether these effects could be attributed solely to insulin levels or other factors such as improved nutrition and lifestyle changes.

Another small-scale study examined the impact of metformin on hair shedding among patients taking insulin for type 2 diabetes. The authors reported no differences in rates of hair loss between groups receiving metformin and those who did not receive this medication. While this study suggests there may not be a direct correlation between insulin and hair loss, larger-scale studies are needed to confirm these findings. With that said, other factors such as genetics, stress level, diet, hormonal imbalances, and certain medications may also influence a person’s likelihood of experiencing hair loss.

Other Factors That May Affect Hair Loss

Although clinical trials have not been able to conclusively prove that insulin causes hair loss, there are a number of other factors which could also play a role. For example, certain medications and medical conditions can lead to changes in hormone levels, particularly those related to thyroid function or the male hormone testosterone. This can result in thinning or even complete baldness for some people. In addition, lifestyle choices such as diet and exercise can impact hair growth and health. Poor nutrition or physical inactivity can interfere with proper scalp circulation and lead to weak follicles or breakage of existing hairs.

Stress is another factor that may contribute to hair loss, as it increases cortisol production which has been linked to alopecia, a type of hairless condition. It’s important for individuals under significant stress to take steps towards managing their emotions through relaxation techniques like yoga or meditation so they don’t experience long-term damage due to prolonged elevated cortisol levels. Finally, genetics should not be overlooked when trying to identify potential causes of hair loss. If someone in your family suffers from alopecia then you may want to consider genetic testing before starting any treatment plan.

Though these various elements all influence our overall hair health, it’s important to note that each individual reacts differently depending on their unique combination of circumstances – what works for one person might not work for another. Therefore, it’s best practice for anyone experiencing excessive shedding or slow growing locks to consult with a healthcare professional who will assess their particular situation and provide appropriate advice tailored specifically for them.


The evidence from observational studies, clinical trials, and other factors all suggest that there is a link between insulin levels and hair loss. Although it’s still unclear if there is a direct correlation between the two, one thing is certain: people with diabetes tend to have higher chances of experiencing hair thinning or balding than those without the condition.

It’s important to note that nearly 10% of adults in the United States suffer from diabetes – an interesting statistic which indicates how common this disease truly is. Therefore, understanding the connection between insulin and hair loss may be beneficial for managing symptoms associated with diabetes-related issues.
