Prevent the Hair Loss while Taking Phentermine

Hair Loss on Phentermine

Do you experience hair loss on Phentermine? To minimize, prevent and regrow it, you need to know some of the causes of your hair loss while taking this prescribe-only diet pills.

Because hair loss isn’t known to be one of the side effects of taking phentermine, you won’t find it on the list of side effects, whether common or uncommon. Even so, many women notice that their hair starts to fall out or thin when they start taking phentermine. Given this, it would suggest that taking phentermine can cause hormonal changes. It could also be a problem associated with rapid weight loss.

The form of hair loss is known as Alopecia, and it typically begins around three months into taking phentermine. It can continue for as long as you continue to lose weight. This phentermine hair loss is not caused by the dietary changes people make, including restricting calories or cutting out certain foods, but taking phentermine and losing weight can cause hormonal changes.

It might not be easy to spot the hair loss at first because hair follicles remain dormant on the head for several months even after the damage has been done. In fact, your body is already starting to correct the hair loss by the time you notice it. A few weeks after you begin to lose your hair you should feel small hairs growing out of your scalp; a sign that the hair has regrown.

The hair loss you experience on phentermine is caused by the hair coming out at the root. This is the kind of normal hair loss you should expect to happen when washing and brushing your hair, just at a much faster rate.

However if the hair becomes dry and brittle and starts to break away, then it could be a sign that you have an underlying medical condition. One such condition that causes this is hypothyroidism. If you notice hair loss, then it’s important that you report it to your doctor right away, even if you think it has nothing to do with taking phentermine.

How to Minimize Phentermine Hair Loss

There are some reasons you might lose your hair while taking Phentermine. Many of these problems can be treated through eating a balanced diet and using multivitamins to get the other nutrients you could be missing.

Here are some of the primary reasons that people begin to lose their hair on phentermine and how you can mitigate the damage.


Hair is primarily made of proteins. So, a lack of protein can often trigger the body to stop the production of hair. If you add a lack of protein to the hormonal changes and the dramatic weight loss, you could end up with hair loss on phentermine. To counteract this, you need to get enough protein. The RDA of protein is 46g a day for women and 56g a day for men.


Around 10% of women between the ages of 20 and 49 suffer from anemia because they have an iron deficiency. This can lead to hair loss and other symptoms such as fatigue, dizziness, and having an ashen complexion.

If you suspect that you might have an iron deficiency, then you can have your doctor perform a blood test to find out for sure. If you do, then an iron supplement is all you need to solve the problem.

Not getting enough iron in your diet can also make it difficult for you to lose weight, so you might want to consider eating iron-rich foods such as leafy greens and lean red meat to get more iron, burn fat, and lose weight with phentermine.

Vitamin B

Having a vitamin B deficiency is another common cause of hair loss that can be easily treated. People who take Phentermine are commonly advised to get some injections of vitamin B12 to boost their energy, but they would have more success taking a B-vitamin complex multivitamin. This is because the modern American diet lacks other B-vitamins such as folate, according to the National Health and Nutrition Examination Survey (NHANES).

B-vitamins can also be used to minimize the other side effects of phentermine including depression, dry mouth, and anxiety. Every B-vitamin is also involved in the process of converting food into energy.

When it comes to hair loss vitamin B7 (Biotin) has been shown to prevent hair from thinning. As such you want to make sure you have enough of this vitamin if you’re worried about losing your hair on phentermine.


It’s recommended that anyone who has problems with their weight have their thyroid checked. It’s becoming ever more common for women to develop hypothyroidism, which is when the thyroid doesn’t work as efficiently as it should.

Hypothyroidism causes more than just weight problems. It also causes hair loss. The good news is that you can correct the problem with the use of synthetic thyroid medication to get your thyroid functioning normally again. This undoes the damage caused by an underactive thyroid including hair loss and weight gain.


Polycystic Ovary Syndrome (PCOS) is similar to hypothyroidism in that it can cause weight gain and hair loss because it causes hormonal imbalances. Women with PCOS find that phentermine is an excellent way to get back their healthy lifestyle and begin exercising and eating properly again, which makes it much easier for them to lose weight. This, in turn, reduces the symptoms of PCOS and brings their hormone levels back to normal to reverse the symptoms of PCOS including hair loss and infertility.

Dramatic Weight Loss

One of the main reasons that phentermine causes hair loss is because of the dramatic weight loss. Phentermine can cause you to lose a lot of weight, which can lead to hair loss.

The body recognizes sudden weight loss as a kind of physical trauma that causes hair loss, even if losing weight is a good thing, as would be the case when you’re losing weight as a result of being prescribed phentermine for Obesity.

If you want to avoid losing your hair due to losing weight, then you should eat enough calories to fuel your activity levels and power your metabolism. That way you will continue to lose weight at the healthy rate of around 2lbs per week. That way you shouldn’t lose any muscle because you missed out on food groups or went on an extreme diet.

  1. I have used Adipex for weight loss in the past and I am currently taking it again. It works well to supress my appetite, and I lose weight rapidly. However, each time I have used this rx I have experienced a tremendous amount of hair loss. It comes out badly when I wash it, and I see it falling out all during the day. This usually starts around the third month of taking Adipex. Therefore, once again I have to stop the rx and my weight goal will never be reached. I don’t think I have any physical problems or lack of vitamins that causes my hair to come out. I am convinced it is the medicine and am stopping it again. I don’t think I will use Adipex for weight loss again.

  2. I also been taking Adipex and I’ve been on it approximately for 1 year at first I just didn’t notice but my hair started falling out around the my forehead and it has drastically been falling out ever since I’ve been on the Adipex.
