60. CAN LOW CARB DIETS RESULT IN HAIR LOSS

​Here’s an interesting article I came across, which I thought could benefit certain newbie low- carbers suffering from hairloss. People often need to give this healthy lifestyle change a chance and should allow the body some time to settle, detox and sort out issues before they can experience the full benefits of THE LCHF LIFESTYLE.

Is it possible to lose hair when starting a low-carb diet?
Yes, and there are many myths and misunderstandings about it. Here’s what you may need to know.

Temporary hair loss can occur for many different reasons, including any big dietary change. This is especially common when severely restricting calories (e.g. starvation diets, meal replacements) but it can also occasionally happen on low-carb diets.
If so, it usually starts 3-6 months after starting a new diet, at which point you’ll notice an increasing amount of hairs falling out when brushing your hair.
The good news is that even if you should be so unfortunate this is only a temporary phenomenon. And only a percentage of the hair will fall out (the thinning will rarely be very noticeable to others). After a few months all the hair follicles will start to grow new hair, and when they have regrown your hair will be as thick as before again. Of course, if you have long hair this could take a year or even more.

 
Background
To understand exactly what is happening it’s necessary to know the basics of how hair grows. Every single hair on your head usually grows for about 2-3 years at a time. After that it stops growing for up to 3 months. Then a new hair starts growing in the same hair follicle, pushing the old hair out. Thus you’re losing hairs every day, but as the hairs are unsynchronized it’s not so noticeable. You lose one hair and another starts growing, i.e. you always have about the same number of hairs on your head.

Stress and synchronized hair loss
If your body experiences significant stress more hairs than usual can enter the resting phase at the same time. This can happen for many reasons, like these:
Starvation, including calorie-restricted diets and meal replacements

Diseases

Unusually demanding exercise

Pregnancy

Breast feeding

Nutrient deficiencies

Psychological stress 

Any big diet change

Then as the new hairs start growing a few months later all these formerly resting hairs will fall out at almost the same time. This is called “telogen effluvium” in fancy medical terms (read more about it), and it’s relatively common.

What to do
If there was an obvious triggering factor 3-6 months before you noticed the problem – such as giving birth or transitioning to a strict low-carb diet – you don’t really have to do anything. In all likelihood the problem will be temporary. As long as you eat a varied and nutritious low-carb diet it’s very unlikely that stopping it will speed up the hair regain, it will likely happen as quickly anyway. And unfortunately you can’t stop the hair loss from happening once it’s started, as the resting hairs will fall out no matter what you do.
It’s possible to run blood tests for nutrient deficiencies, but unless you are on a vegetarian or vegan diet (with no supplements of iron, B12) it’s unlikely that they will show anything interesting.

How to minimize the risk of hair loss when starting low carb
First, temporary hair loss is relatively rare after starting a low-carb diet, most people never notice anything like it.
There are no studies on how to minimize this small risk, but it’s likely helpful not to restrict calories, i.e. don’t do a low-carb and low-fat diet (AKA“starvation”). Instead eat as much fat as you need to feel satisfied and not hungry on a LCHF diet. It may also be helpful to reduce other sources of stress during your first few weeks on low carb. Sleep well, be kind to yourself in general, and preferably don’t start an intense exercise program at the same time.
