Stress levels are high, and for some, that could mean less hair on your head. Indeed, science supports the notion that significant stress can cause hair loss. So, if you have an important day, like your wedding, hair loss can occur.
It is considered normal to shed about 100-200 hairs per day (check out this hair shedding scale to get an idea of what 200 shed hairs looks like), but the exact number varies based on the individual or hair care practices. Hair loss due to stress can cause you to lose hair in patches, but the good news is, it’s temporary and should return to its pre-effluvium density, although this process is generally slow. It can take months (but generally less than 6) before the shedding stops, and then months to years for lost hair to grow back at the sluggish rate of ~½ inch per month.
