Does Wearing a Hat Cause Hair Loss?

When you’re worried about thinning strands, it’s easy to convince yourself that everything is the culprit. For instance, many people think wearing a hat contributes to hair loss because of the hairs they see when they take it off. Is this fact or fiction? Maybe a little of both.

The Science of Hair Loss

Since hair loss is primarily caused by genetic and hormonal factors, there is no scientific evidence to show that wearing a hat on a regular basis has any effect on hair thinning. Some people think that wearing hats causes hair loss because they see strands in the hat when they take it off. However, it is normal to shed hair every day—the average person sheds up to 100 strands in a 24-hour period, and people with very thick or thinning hair may shed even more.

Rather than hats and other headgear rubbing at hair follicles, the primary culprit of hair thinning is a male steroid hormone called dihydrotestosterone (DHT). Elevated levels of DHT can cause hair loss. Some people are genetically more sensitive to DHT, and even normal levels of the hormone can cause their hair to shed.

The Hat Effect

While wearing a hat will not cause hair thinning, it can cause other issues that may hurt your scalp. Hats that do not fit can rub at your scalp, increasing sweat and irritation. Tight-fitting hats can restrict blood flow to the scalp, causing strands to fall out. While this may only lead to temporary hair loss, your long-term scalp health may be affected. Overall, it is important you keep your hat clean and dry as an infection caused by a dirty hat can lead to long-term damage to your scalp and potential hair loss.

So, good news: your hat isn’t causing your hair to fall out. More good news: if you’re worried about thinning hair, we’ve got you covered. Try our Activating Serum today to grow a head of hair you won’t want to hide.
