Drugs can often have unwanted side effects, and hair loss may just be one of them. While it’s true that some medications can help you to grow hair, it’s also true that there are medications that can cause excess hair loss!
The issue is that the drug may be affecting either the growth phase of the hair, or the resting phase of the hair. Your hair follicle grows during the anagen phase, which usually lasts three to four years. Your hair follicle rests during the telogen phase, which usually lasts three to four months. At the end of the telogen phase, the existing hair falls out, and a new hair begins to grow.
Medications can cause two kinds of hair loss called telogen effluvium and anagen effluvium. Of the two, telogen effluvium is most common. If hair loss is related to a specific drug, it will generally start within two to four months of starting the new prescription. With telogen effluvium, the drug is influencing hair follicles to go into dormancy early – therefore, falling out early. With this type of hair loss, people will lose 100 to 150 hairs daily. This amounts to about 30 percent more hair loss than normally.
A large number of drugs can cause hair loss. Common drugs that will affect hair include acne medications, antibiotics and antifungals, birth control pills, cholesterol drugs, high blood pressure drugs, steroids and nonsteroidal anti-inflammatory pain medications.
If a prescription drug is causing anagen effluvium, then the drug is preventing the matrix cells in the follicle from dividing normally. This stops the hairs from growing properly and they fall out. If your medication is causing this kind of hair loss, it will become obvious within a few days or weeks. Chemotherapy is the most common cause of this kind of hair loss, and can be quite severe.
In most cases, if you stop the offending medication, then the hair loss stops. However, it can take as much as three months for the hair loss to end. If you are on multiple medications, you may need to stop one at a time to determine which drug is the problem. Your doctor will know alternative medications that you can take to manage the same health condition – but without the negative side effect of hair loss.
When you stop taking a drug, but the hair does not come back, you may need additional help. In this case, it’s time to consider hair products that nourish the scalp, and even other prescriptions that help to grow hair. If you are looking for natural products to promote hair growth, good options include products like SureThik Shampoo and Serum. When the scalp is nourished well, you have the best chance to grow healthy hair.
In some cases, you will need to be evaluated for medical treatment of drug-induced hair loss. A doctor who specializes in hair loss will be best able to evaluate you for the best possible treatment, whether that is hair growth medications, hair transplantation, or other options.
