Study Examines Effect Of Smoking On Early AGA

Dermatology Advisor reports, “People who smoke have a higher prevalence of early onset androgenetic alopecia compared with nonsmokers, but many smokers with this form of pattern hair loss more often report a negative family history for the disorder,” research indicated in a study that “enrolled

1000 healthy men between the ages of 20 and 35 years without any local scalp condition.” All “participants were divided into 2 equal groups: people who smoked (n=500) and people who did not smoke (n=500).” The findings were published online in the Journal of Cosmetic Dermatology.

People develop noticeable hair loss after recovering from COVID-19

On the AAD website an article explains that months after recovering from COVID-19, many people find that their hair is falling out in large clumps: If we’ve learned anything from the coronavirus pandemic, it’s to expect the unexpected. The hair loss that many people develop, however, may not be so

unexpected. Here’s why. Temporary hair loss is normal after a fever or illness Fever is a common symptom of COVID-19. A few months after having a high fever or recovering from an illness, many people see noticeable hair loss. While many people think of this as hair loss, it’s actually hair shedding. The medical name for this type of hair shedding is telogen effluvium. It happens when more hairs than normal enter the shedding (telogen) phase of the hair growth lifecycle at the same time. A fever or illness can force more hairs into the shedding phase. Most people see noticeable hair shedding two to three months after having a fever or illness. Handfuls of hair can come out when you shower or brush

your hair. This hair shedding can last for six to nine months before it stops. Most people then see their hair start to look normal again and stop shedding. Stress can cause temporary hair shedding. Even if you never developed a fever or COVID-19, you may still see hair shedding. Emotional stress can also force more hairs than normal into the shedding phase. And who isn’t feeling more stressed and anxious during the pandemic?

Again, the hair shedding begins about two to three months after the stress starts. While seeing your hair fall out in clumps can add to your stress, it’s important to try to de-stress. Only when the stress ends will the excessive hair shedding stop. Hair tends to return to normal on its own. When the cause of your hair shedding is due to a fever, illness, or stress, hair tends to return to normal on its own. You just have to give it time. As your hair grows back, you’ll notice short hairs that are all the same length by your hairline. Most people see their hair regain its normal fullness within six to nine months.
