- Mechanism: Metformin may cause hair loss by interfering with the hair growth cycle.
- Prevalence: Hair loss is a relatively common side effect of metformin, affecting up to 10% of patients.
- Severity: Hair loss caused by metformin is usually mild to moderate.

Hair loss is a potential side effect of metformin, but it is important to remember that it is usually mild and reversible. If you are concerned about hair loss, talk to your doctor. There are a number of things that can be done to manage hair loss caused by metformin.
Mechanism
Metformin may cause hair loss by interfering with the hair growth cycle. The hair growth cycle has three phases: the anagen phase, the catagen phase, and the telogen phase. Metformin may prolong the telogen phase and shorten the anagen phase, which can lead to hair loss.
-
Anagen phase
The anagen phase is the active growth phase of the hair cycle. During this phase, the hair follicle produces a new hair shaft.
-
Catagen phase
The catagen phase is the transitional phase of the hair cycle. During this phase, the hair follicle shrinks and the hair shaft is released from the follicle.
-
Telogen phase
The telogen phase is the resting phase of the hair cycle. During this phase, the hair follicle remains dormant.
-
Metformin and the hair growth cycle
Metformin may prolong the telogen phase and shorten the anagen phase. This can lead to hair loss because there are fewer hairs in the active growth phase and more hairs in the resting phase.
Hair loss caused by metformin is usually mild and reversible. However, if you are concerned about hair loss, talk to your doctor. There are a number of things that can be done to manage hair loss caused by metformin.
Prevalence
Hair loss is a potential side effect of metformin, a medication commonly used to treat type 2 diabetes. The prevalence of hair loss caused by metformin is relatively common, affecting up to 10% of patients. This means that a significant number of people who take metformin may experience hair loss as a side effect.

-
Temporary nature
Hair loss caused by metformin is typically temporary and will resolve once the medication is discontinued. This is because metformin does not cause permanent damage to hair follicles.
-
Duration of recovery
The duration of recovery can vary depending on individual factors, but in most cases, hair will start to regrow within a few months after stopping metformin.
-
Complete recovery
In most cases, hair loss caused by metformin will fully recover once the medication is stopped. However, in some cases, hair loss may persist even after the medication is discontinued.
-
Individual variability
The reversibility of hair loss caused by metformin can vary from person to person. Factors such as the dose of the medication, the duration of use, and the person's overall health can influence the recovery process.
Understanding the reversibility of hair loss caused by metformin can help patients make informed decisions about their treatment options. If hair loss is a concern, patients can discuss with their doctor the potential risks and benefits of metformin and explore alternative treatment options if necessary.
Management
Managing hair loss caused by metformin is an important aspect to consider when discussing the potential side effects of this medication. Fortunately, there are several approaches that can be taken to address this issue.

-
Oral finasteride
Oral finasteride is a medication that is taken by mouth to prevent hair loss. It is a prescription medication that has been shown to be effective in managing hair loss caused by metformin.
-
Other treatments
In addition to topical minoxidil and oral finasteride, there are a number of other treatments that may be helpful in managing hair loss caused by metformin. These include laser therapy, platelet-rich plasma (PRP) injections, and hair transplantation.
-
Lifestyle changes
Certain lifestyle changes may also be helpful in managing hair loss caused by metformin. These include eating a healthy diet, getting regular exercise, and reducing stress.
The best approach to managing hair loss caused by metformin will vary depending on the individual patient. It is important to talk to a doctor to determine the best course of treatment.
Alternatives
When considering the potential side effects of metformin, it is important to be aware of the available alternatives for treating type 2 diabetes. If metformin is causing hair loss, there are a number of other medications that can be used to manage blood sugar levels effectively.
-
Sulfonylureas
Sulfonylureas are a class of medications that work by stimulating the pancreas to release more insulin. They are commonly used to treat type 2 diabetes and can be an effective alternative to metformin.
-
Thiazolidinediones
Thiazolidinediones are a class of medications that work by increasing the body's sensitivity to insulin. They are commonly used to treat type 2 diabetes and can be an effective alternative to metformin.
-
DPP-4 inhibitors
DPP-4 inhibitors are a class of medications that work by inhibiting the enzyme DPP-4. This enzyme breaks down incretins, which are hormones that stimulate the pancreas to release insulin. By inhibiting DPP-4, DPP-4 inhibitors can help to improve blood sugar control.
-
GLP-1 agonists
GLP-1 agonists are a class of medications that work by mimicking the effects of GLP-1, a hormone that stimulates the pancreas to release insulin and slows down gastric emptying. They are commonly used to treat type 2 diabetes and can be an effective alternative to metformin.
The best alternative to metformin will vary depending on the individual patient. It is important to talk to a doctor to determine the best course of treatment.
