This next question
comes from Sydney via Facebook.
She ask I’ve been losing weight and eating healther.
Why is my hair falling out.
Such a frustrating phenomenon.
So we’re trying to be healthier
and now all of a sudden something bad happens like this,
what’s going on?
Well,I think there, when you talk about suddenly losing your hair
that often comes from a shock to the system.
So in this case maybe she’s exercising a lot more,
it’s just a severe physiologic stress.
And it has a fancy name
because dermatologists love jargon,
it’s called Telogen Effluvium，
and we see this often,
We see this often after childbirth,
actually that’s the most common one
but any acute sickness
,certainly surgery, in this case a major shock to her system
if she’s changed all her ways.
And the reason for it is because at any given time,
any one hair on your head
is actually either growing, resting or being shed.
That’s the normal hair growth cycle.
But when you shock your system like this,
you sort of redirect the circulation to the follicles,
you really interrupt that normal cycle.
You’re gonna prematurely shed all those hairs,
they’re going to be put into that cycle really quickly.
And the thing to reassure people about this is it’s
never permanent and it’s never scarring,
if that’s the cause of it.
So it usually runs about a four to six month cycle,
if anyone’s ever had this after childbirth,
they know you get these baby fine hairs and they grow back,
but it can be incredibly stressful and really frustrating like you said
because a lot of times you’ll get this after new medication
or after a new workout regimen
where you’re trying to do everything right,
and then you feel like things are going downhill.
But we don’t know exactly what she’s doing.
Is she getting enough calories?
Is she getting enough protein?
Because we know
that if you really are subjecting your body to extremes,
we see that with people with eating disorders,
one of the first things, that you see they complain about is losing their hair.
So you’re dieting
, you want to make sure that you’re doing it the right way.
You don’t want to crash not getting enough calories
and always want to make sure that you’re getting protein.
But to your point about any type of stressful event,
we see this so often with facelifts,
that you don’t lose hair when we do a facelift,
we do incisions in front of the hairline
but so many women and men say
‘Oh you know, I’m losing hair’,after this facelift,
噢 你知道的 整容之后我脱发了
it’s just a temporary effect of a shift in the blood flow,
the stress of surgery, the recovery et cetera.
After something like that versus another stress,
like a change in eating habits, exercise,
how long should you give it before you think Okay,
this could be something else.
Probably a few months I would think.
Yeah so usually the onset of this,
like you were saying is a little bit delayed.
It’s about six to eight weeks after the major stressor
and the most common thing is you’re looking in your drain
or you’re looking in your hairbrush or all
of a sudden there’s all this hair and you’re like
where does this come from?
But I think the key thing is if it doesn’t start to correct
within about six months or so,
then you do have to look at your overall medical history.
Is there something autoimmune going on?
Did you start a new medication?
Is there a new medical condition?
What’s your family history?
And certainly if there’s any redness or scale on the scalp
that looks like the scalp is inflamed,
that’s when we really need to dig deeper and look at
other medical reasons this might be going on.
It’s not just the stress mediated a short term thing.
But in the meantime if you are going through this,
like you said, make sure you’re getting enough protein,
that you can support the keratin of the follicles.
Make sure you’re taking enough zinc,
that’s another one that really helps in terms of follicular health and then certainly
if you’re deficient in it,
biotin which is a B Vitamin super helpful,
at least two and a half milligrams.
Okay, before we go, can the next question,
好的 在我们走之前 下一个问题
can you say it one more time?
Say that ten times in a row!
