Welcome to the Dr. Berg's Healthy Keto and Interminute Fasting Podcast, where Dr.

Berg takes you on the journey for the truth about getting healthy and losing healthy weight.

I want to talk about the importance of vitamin D with your hair.

There's a huge association between hair loss and low vitamin D levels.

Let me tell you why, because right beneath your skin, so you can see your hair right here,

but right beneath the skin, there is something called the follicle, and that's kind of part

of the root.

And on that root area, you have sebaceous glands, which produce an oil and like a waxy substance

that goes into the hair that protects the hair.

There's also antibacterial things in there, and it does a lot of other things.

Both the sebaceous gland and the follicle, which is deep in the skin, have vitamin D receptors.

Now, there's various growth stages of your hair, and there's one called antigen.

And this is the new hair growth stage.

It's the first stage from follicle to the full grown hair.

And this stage is dependent on vitamin D.

And so that follicle that actually is an organ.

Now, you think about organs, it's like the heart, the liver, the kidney, but your follicle isn't organ two.

And this little organ underneath the skin has 20 different cell types that regulate the growth of the hair,

and there's all sorts of hormonal involvement, immune cell involvement, and certain proteins that help regulate this hair.

And what they found with people that have hair loss, and a type of hair loss called alopecia,

which is an autoimmune condition where you have patches of hair falling out.

There's been a higher level of mutations with vitamin D, and I'm talking about the receptor for vitamin D.
