It’s normal to lose some hair every day, but how much? What causes hair to thin, and is there anything that can be done to stop the progress? Brian Ely, DO, a family doctor at University of Utah Health, explains.

Q. How much hair do people typically lose daily?

A. Normal hair loss is 75 to 100 hairs a day. If you notice you’re losing more hair, if it falls out in clumps or if you’re experiencing pain, visit your doctor.  

Q. Why does hair thin?

A. Although there is a genetic component, the most common cause of thinning hair is hormonal changes over time. Medical conditions, medication and stress can also contribute to hair loss. 

Q. Do vitamins supplements help hair grow?

A. They are unlikely to help unless the thinning is caused by a vitamin deficiency, which isn’t usually the case in the U.S.

Q: What can be done to treat thinning hair?

A. Some over-the-counter treatments are effective, although it usually takes several months of consistent use to work. Prescriptions and surgical options may also help. Speak with your doctor to find out what’s right for you.
