What Causes Hair Loss

Can Blowdrying Your Hair Cause Hair Loss?

We have all heard the stories how wearing a tight fitted hat too often will cause hair loss or that if you wash your hair too often it will fall out. Well, they're both myths and old wives' tales, but what about blowdrying your hair? In this article, we will discuss whether or not blowdrying your hair can cause hair loss.

Do Blowdryers Cause Hair Loss?

There is no scientific evidence that suggests that blowdryers cause hair loss. This is a common misconception often relayed by individuals without any real knowledge of hair loss. There are different forms of hair loss, but the most common form of hair loss is androgenic alopecia (genetic hair loss), this form of hair loss follows a distinct pattern for men and women.

Why Do Some Believe That Blowdryers Cause Hair Loss?

The misconception stems from the thought that high heat kills hair follicles. Using a blowdryer on high heat may cause the follicles to become brittle and breakable thus, causing excessive shedding that may appear to be hair loss. This is undoubtedly not the best thing to do for your hair, but this does not cause permanent hair loss, as seen with androgenic alopecia (genetic hair loss).

So What Causes Hair Loss?

Hair loss can be caused by a multitude of reasons including a poor diet, low iron levels, thyroid disorders and some prescribed medications may have hair loss listed as a side effect. However, the most common form of hair loss is androgenic alopecia (genetic hair loss), which is an inerited gene from either the mother or the father's side of the family, but the actual mechanism that triggers hair loss is hormonal. Hair follicles, as well as sebaceous glands contain a high level of an enzyme called 5-alpha reductase. This enzyme is responsible for converting testosterone in to dihydrotestosterone (DHT) through the blood stream. DHT is the main hormone responsible for causing male and female pattern hair loss.


While blowdrying ones hair on high heat may not be the best thing to do for our hair, it certainly won't cause permanent hair loss or permanent damage. However, anyone that suspects that they may be suffering from androgenic alopecia (genetic hair loss) should consult with a pre-screened hair restoration physician, to receive a proper diagnosis and treatment plan.
