Dr. Sarah Hallberg: Do ketogenic diets cause hair loss?

All right, here’s another
common one that I get
from a lot of patients.
So I’ve noticed I’m losing hair on keto.
Is this normal, and
what can I do about it?
– So I can be, and it’s very
important to say what we should
really turn this into because
what is much more true is
I’m losing hair with rapid
weight loss because it probably
has nothing to do with the diet itself.
It’s the fact that the diet
is causing weight loss.
And we do get this question a
lot, and here’s how I like to
explain it to my patients
in a way that they can
really understand.
And that is when women have
babies, they don’t go home
from the hospital with hair loss, right?
But what they will find is
that when that baby is four,
maybe six months old, all
of a sudden they’re starting
to lose hair, and that’s
because giving birth is a big
shock to the system, right?
I mean it’s obviously a
good one, we all love it,
but it is a big shock to the system.
Weight loss is the same way.
It’s a big shock to the system.
We love it, we wanna have
it, but again weight loss
is likely to occur four to
six months after the beginning
of a period of rapid weight loss,
and that’s because the
hair grows in phases.
So what I tell patients
here is be patient.
Let the phase pass, and then
the hair will come back.
If people are really
worried about it I’ll say,
start taking some B-complex vitamins.
I mean I don’t think
there’s gonna be any problem
with patients doing that.
Whether or not that’s
gonna help, hmm, it might,
but the bigger thing is
you just gotta give it time
and let that phase pass.
