Phentermine is a weight-loss drug that has been used to treat obesity and aid in dieting. It works by suppressing the appetite, but can it cause hair loss? This article will explore whether or not phentermine use causes hair loss, as well as what other side effects may be associated with taking the medication.

For those who are looking for an effective way to lose excess weight, phentermine might seem like an attractive option. But before you decide to take this medication, it’s important to know exactly how it works and all of its potential risks. We’ll discuss if there is any scientific evidence linking phentermine usage and hair loss so that you can make an informed decision about your health.

How Does Phentermine Work?

Phentermine is a prescription drug used to help people lose weight. It works by suppressing the appetite and stimulating the body’s metabolism, thereby helping burn fat more efficiently. Phentermine also releases chemicals in the brain that stimulate feelings of well-being and euphoria, which can reduce cravings for unhealthy foods.

Because phentermine affects hormones in the body, there are some potential side effects associated with it. These include insomnia, dry mouth, constipation, an increased heart rate and blood pressure levels. There have been reports of hair loss as a result of taking this medication; however, these cases are rare. With any type of medical treatment or supplement it’s important to discuss possible risks with your doctor before making any decisions. Now we turn to whether there is evidence linking phentermine and hair loss.

Is There Evidence Linking Phentermine And Hair Loss?

Research into the potential link between phentermine and hair loss is limited. However, there are reports from some individuals who have taken phentermine and experienced subsequent hair loss. Anecdotal evidence suggests that this may occur due to hormone changes in the body caused by the drug or other unknown factors.

It’s difficult to determine whether a causal relationship exists between taking phentermine and experiencing hair loss, as factors such as genetics, lifestyle habits, medications, stress levels, and diet all play an important role in determining one’s overall health. So far, research has yet to provide any definitive answers on this topic. As such, it’s important to pay attention to any signs of hair thinning or shedding while taking phentermine so that it can be addressed with a healthcare professional if necessary. With this said, further investigation is needed before drawing conclusions about a possible connection between the two. To better explore what could potentially be behind these reported cases of sudden hair loss after starting Phentermine treatment, let’s take a closer look at what side effects may come along with taking phentermine.

What Are The Possible Side Effects Of Taking Phentermine?

Phentermine is a prescription weight loss medication. While this drug can help with appetite suppression and improved energy, it may also come with some side effects. Hair loss is one possible issue that could occur when taking phentermine. It’s important to understand the potential risks before starting on any medication regimen.

Hair loss from phentermine can take place in two different forms: telogen effluvium or anagen effluvium. Telogen effluvium occurs when a large number of hairs enter the resting phase at once, causing thinning and shedding over time. Anagen effluvium is more serious and happens suddenly after exposure to certain toxins or drugs like phentermine. In either case, hair growth will usually return to normal if the underlying cause is addressed by your doctor and you stop using phentermine as directed.

It’s best to be aware of all the potential risks involved with taking any medication, including phentermine. If you experience sudden hair loss while using this drug, contact your doctor right away for advice and further treatment options.


In conclusion, it appears that phentermine can potentially cause hair loss. While the evidence is inconclusive and further research needs to be done, I believe it should still raise some concern for those who are considering taking this drug. On one hand, there may be some benefit from using phentermine if you’re struggling with weight loss; however, on the other hand, you could end up losing more than just a few pounds – your hair included. Ultimately, my advice would be to weigh the pros and cons of taking phentermine before making any decisions.
