everyone loses some scalp hairs everyday. that's normal and usually not very noticeable. but there's a frightening form of very rapidhair loss that causes 30%, or even up to 50% of your hair to shed injust a few weeks. it's called telogen effluvium.
crash diet one month, and today, i'll tell you why it occurs andwhat you can do. hello, i'm dr. neal schultz [pause]
and welcome to dermtv. in other dermtv episodes, i've mentioned that most people normally lose100 to 150 scalp hairs daily. but even if you see some of those hairs inthe shower drain, the good news is your hair isn't thinning because you grow the same number of new hairsas you lose, every day, maintaining the status quo. but very rapid frightening hair loss resulting in visible thinning of your scalphair occurs
in a condition called telegen effluvium. it results from a resetting of the scalp hairgrowth cycle. in this case, instead of 5 to 15% of the hairfollicles being in the resting phase... and it's the hairs in the resting phase thatnormally shed... instead of 5 to 15%, 30 to 40, or even 50%of the follicles enter the resting phase at the same time. as a result, all of those hairs are shed synchronously2 to 3 months later causing massive, rapid hair loss. but don't despair! the follicles aren't damaged.they're just sleeping.
and just as 30 to 50% went to sleep at thesame time, that same 30 to 50% will wake up and startre-growing at the same time as well. so 6 to 8 months later, there won't be anynet hair loss. all the fallen hairs will have regrown! of course, this takes patience and faith! and i often recommend topical minoxidil forwomen and propecia pills for men during that time,just to help the regrowth. the most common cause of telegen effluviumis childbirth... in which case it's called postpartum alopecia.
so predictably in the 3rd or 4th month aftergiving birth, many women experience this frightening buttemporary hair loss. other causes include high fevers, any surgeryinvolving general anesthesia, very rapid weight loss from severe calorierestriction from a crash diet, emotional disorders, and severe stress. telogen effluvium can affect hair on all partsof the body, but, generally, only the loss of scalp hairis symptomatic or clinically noticeable. if you experience significant and rapid hairloss 3 to 4 months after one of the causes i just mentioned,
shampoo regularly and at least try over thecounter topical minoxidil. for reassurance, see your dermatologist. and for the brave of heart, just keep the faith!
