It is normal to lose some hair every day. However, if you are losing an excessive amount of hair, possible causes include stress, giving birth, genetics, and certain prescription drugs. Among the medications that cause hair loss are some very common ones like antibiotics and birth control pills.
Most of the time, you may only experience temporary hair loss when taking certain medications. Once you stop taking the medication or modify the dosage you are taking, your hair will grow back. Other times, that is not the case. Some medications may lead to male or female pattern baldness and permanent hair loss.
It is important to find out what the side effects are before using the medication. Hair loss may be a potential side effect. You should be aware that not all medications that cause hair loss will have the same effect on everyone taking them. The severity of the hair loss will depend on the drug, the dosage you are taking and your body’s sensitivity to that particular drug.
The Top 10 Medications that Cause Hair Loss
Here is a listing of the top 10 medications that can cause temporary or permanent hair loss, and a listing of some others:
- Acne medications (that contains Vitamin A): While you are fighting those stubborn pimples and acne, you could be losing your hair. The key ingredient in some acne medications is Vitamin A in its processed form (retinoids, retinol). Note, that this is not a notable risk when Vitamin A is provided in its provitamin form, beta carotene. The precursor beta carotene is only converted into Vitamin A’s active form by the body when it is needed, avoiding toxicity. When taken in large dosages, Vitamin A can lead to telogen effluvium – when the hair follicles go into their resting phase (telogen) too early and causes more hair to fall out. You may notice that your hair doesn’t fall out immediately after you begin taking the drug – it will begin between two and four months after beginning the medication. Medications with Vitamin A include Accutane and Retin A. Current recommended daily are allowances for Vitamin A are:
- Men, 19 years and older: 900 mcg
- Women, 19 years and older: 700 mcg
- Pregnant women, 14 to 18 years: 750 mcg
- Pregnant women, 19 years and older: 770 mcg
The solution for hair loss while taking a Vitamin A-based medication is to lower the dosage.
- Antibiotics and Antifungals: One of the hidden dangers of antibiotic use is hair loss. Antibiotics are known to reduce hemoglobin and Vitamin B levels, sometimes making hair fall out faster. Hemoglobin is a protein found in your red blood cells responsible for transporting oxygen from the lungs to the body’s tissues and carbon dioxide from the tissues to the lungs. Hemoglobin and Myoglobin are also important for storing iron. Decreased hemoglobin will lead to an iron deficiency, which will in turn cause your hair to become brittle, dry and even fall out. Vitamin B or the B-Complex Vitamins (including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid), and B12 (Cobalamin)) are very important for maintaining healthy hair growth, thickness and shine.
- Anti-Convulsants/Epileptic medications: Anticonvulsants, or anti-seizure medications, can also cause hair loss. Medications include trimethadione (Tridione) and valproic acid (Depakote).
- Anti-depressants/anti-anxiety medications and mood disorder medications: Certain anti-depressant medications are known to cause telogen effluvium including:
- Amitriptyline (Elavil, Endep)
- Amoxapine (Asendin)
- Clomipramine (Anafranil)
- Desipramine (Norpramin, Pertofrane)
- Doxepin (Adapin, Sinequan)
- Fluoxetine hydrochloride (Prozac)
- Haloperidol (Haldol)
- Paroxetine (Paxil)
- Sertraline hydrochloride (Zoloft)
- Birth control pills/female hormones: Oral contraceptives and hormone replacement therapies can affect your hormonal balance and cause hair loss. Estrogen and Progesterone (female hormones) are hormonal medications that have been linked to female pattern baldness and telogen effluvium in women.
Blood pressure medications: Blood pressure lowering medications such as Beta-blockers and Angiotensin-Converting Enzyme Inhibitors or ACE inhibitors can lead to telogen effluvium. Some include:
- Beta-blockers – Atenolol (Tenormin), Metoprolol (Lopressor), Nadolol (Corgord), Propranolol (Inderal, Inderal LA), and Timolol (Blocadren)
- ACE inhibitors – Captopril (Capoten), Lisinopril (Zestril, Prinivil), Enalapril (Vasotec)
- Blood-clotting medications: Blood thinners such as warfarin sodium (Panwarfarin, Sofarin, Coumadin) and heparincan cause hair loss.
- Chemotherapy and anti-cancer drugs: Among all these drugs, anti-cancer and chemotherapy medications are most known by the general public to cause hair loss not only on the head, but also of facial hair including eyebrows, eyelashes, and other bodily hairs. Chemotherapy not only attacks cancer cells but it attacks all of our healthy cells indiscriminately, including hair follicles. Some chemotherapies that cause hair loss include: Adriamycin, Cyclophosphamide, Cactinomycin, Docetaxel, and Doxorubicin, etc.
- Cholesterol-lowering drugs: Cholesterol drugs including Atromid-S (clofibrate) and Lopid (gemfirbozil) can cause hair loss. Hair loss is a very rare side effect of statin-based cholesterol-lowering drugs. According to studies, cholesterol inhibitors such as Lipitor and Effexor can cause an increase in hair shedding in 1% of cases.
- Male-hormones: Testosterone or anabolic steriods may cause male-pattern baldness
Other medications that cause hair loss
Some additional medications that can cause hair loss include:
- Gout treatments
- Immune-suppressant drugs
- Non-steroidal Anti-inflammatory drugs (NSAIDS)
- Drugs for Parkinson’s Disease
- Thyroid Medications
- Weight loss drugs
It is important to note that most of these treatments are traditional prescription drugs which are synthetically made, and the active ingredients may not be chemically harmonious with your body, and if not properly balanced, will cause hair loss. Additionally, these drugs may have more than one side effect.
Ensuring the proper balance
The overarching lesson is to ensure proper balance when taking medications. Getting the right amounts of vitamins and minerals in your diet is crucial for maintaining healthy hair and to prevent excessive hair shedding. If an adverse effect of your medication is hair loss, the solution may be to take a comprehensive supplement for hair that is powerful enough to counteract the side effects of your medications.
For example, if you are taking an antibiotic or antifungal that causes hair loss as a side effect, you will want to take a B-Complex Vitamin dietary supplement and/or Iron supplement to replenish your Vitamin B and Iron deficiencies. Conversely, if you are taking too much Vitamin A, the solution is to decrease the dosage. The key is getting the right dosage your body needs to do its job.
One way you can maintain proper amounts of vitamins and minerals in your diet to ward off hair loss is to take a hair loss supplement. A good hair loss supplement will include all of the necessary vitamins and minerals your hair needs for healthy growth in the appropriate amounts.
An added benefit would be to find a hair loss supplement that does more than just provide nutrition to hair with vitamins and minerals. Many herbs have historically been used in Chinese or Ayurvedic cultures and medicine to treat symptoms of certain diseases such as hypertension, blood clotting, bacterial and fungal infections, cholesterol, etc. Today, research is showing that some of these herbs can support hair growth.
- Ashwaghanda: An Indian herb, Ashwaghanda has been historically used to treat a number of diseases, including depression and anxiety, degenerative diseases such as Alzheimer’s disease and Parkinson’s, and protect the nervous system. Studies have shown that it may have potent anti-cancer properties. Additionally, Ashwaghanda is a powerful antioxidant and free radical scavenger, also having benefits for hair loss and hair growth.
- Curcumin: Curcumin is a substance in turmeric, a spice, which is a main ingredient in curry powder. Turmeric has been used in Indian and Asian medicine to treat a variety of health conditions because it has anti-inflammatory, antioxidant, and even anticancer properties. Studies have shown that it has anti-inflammatory benefits for people with osteoarthritis and rheumatoid arthritis, and can protect against diseases such as Alzheimer’s, stomach ulcers, colitis and high cholesterol. Studies also show that Curcumin’s anti-inflammatory properties helps to optimize the immune system and fights inflammation that can slow hair growth.
