It’s normal to lose 50-100 hairs on your scalp each day, but what happens when you lose more than that? Hair loss ranges from a mild thinning of the hair, a receding hairline to total baldness. Hair loss can happen on the scalp or all over the body. There are many causes of hair loss and it is important to know what is causing hair loss in order to treat it. Let’s take an in-depth look at what causes hair loss and ways to treat it.
Hair loss, also known as alopecia, is excessive loss of hair from your body, typically on your head. While hair loss sometimes leads to baldness, other times it can just cause overall thinness of the hair. Common types of hair loss include:
The most common cause of hair loss is genetics and age. By 35, two-thirds of men are affected with some degree of hair loss or balding. By the age of 50, 85% of men have notable hair loss. Alopecia affects 40% of women by the age of 50. There are many treatment options for hair loss depending on the cause. These can include shampoos, topical medication, hair transplant surgery, and natural remedies.
There are a variety of reasons for hair loss, so it is important to have it diagnosed by a doctor to find the root cause. While a primary care physician can do some tests for hair loss, such as a blood test to determine thyroid levels, a more complete diagnosis will be done by a dermatologist. There are a variety of tests your dermatologist may perform, some of which may include:
During the appointment with your doctor or dermatologist, it is important to ask questions you may have. Questions to ask your doctor may include:
Currently, there are no cures for hair loss. Medications for hair loss typically do not completely reverse hair loss. Hair loss caused by chemotherapy or fungal infection can be resolved once chemotherapy has ended or the fungal infection has been treated. There is promising research in 3D printing and stem cells for curing hair loss in the future.
Treatment aims to help prevent more hair loss and regrow hair when possible. Possible treatments include medications, hair transplant surgery, laser therapy, or natural and home remedies. There are a few differences in medications to treat hair loss between males and females. The most common medication for hair loss prescribed to men and women is topical minoxidil, or Rogaine, which comes in liquid or foam and is rubbed into the scalp.
Rogaine helps prevent hair thinning and encourages new hair growth. Home remedies may include supplements that encourage hair growth, such as Omega-3, or changing hairstyles that may be damaging to the hair. Scientists are currently working on new treatments in hair loss, such as laser treatment or finding breakthroughs in treating hair loss for cancer patients.
Depending on the type of hair loss it is possible your doctor will prescribe medication. Common medications for hair loss include:
The best medicine for hair loss should be determined by a doctor and depends on your medical condition, medical history, and the current prescriptions you may be taking.

For most causes of hair loss, including thinning, there are medications and natural treatment options to promote new hair growth.
The best treatment for hair loss depends on the underlying cause of the hair loss. It is best to have a conversation with your doctor to find the best treatment for you. One of the most widely used treatments for hair loss is Rogaine.
Since there are multiple reasons for female hair loss, it is best to discuss with your doctor the most effective treatment for hair loss. Common treatments for female hair loss are Rogaine or antiandrogens, which slow down the production of male hormones.
There are exciting developments in 3D printing and stem cells for hair loss treatment. However, they are not yet available to the public.
