If I understand correctly, hair loss can actually mean you have just gone from a state of poor nutrition to one of better nutrition, because hair stops growing and when it starts again it pushes old hair out. Dr. Eades explains it better.

One thing with the paleo diet that gets overlooked is iodine. Not enough iodine can lead to thyroid issues which in turn can lead to hair loss. It's something to look into

Sometimes hair loss accompanies episodes of weight loss. This article is targeted at women but it talks to the point. Should grow back unless you really are going bald.

In ANY weight loss program that you follow, hair loss often occurs at the same time. This is a natural result and the hair will grow back in once you reach your target weight. Often the hair is even thicker than before!

In fact, compared to other diets, the low carb diet is BEST for your hair. Three key vitamins to take to help your hair are protein, iron and zinc - and these are in high supply on a low carb diet. Note that these vitamins will not STOP the temporary hair loss while you diet. The hair loss is a normal part of your body's reaction to losing the weight. However it will help the hair grow in more fully when you have reached your target.

I'm a woman and have had diffuse hair loss (chronic telogen effluvium) since late 2007. It's much worse on one side of my head for some reason. My hair grows in okay at the roots, but much of it sheds out at a very short length. I used to have decently thick hair past my waist - I've had to keep it cut above the shoulders for years because it got so thin past shoulder length.

It started when I was an uncommitted vegan, continued into my first phase of low-carb paleo (which I started with in mid-2009) and has only improved significantly quite recently, months after I added a lot more starch and vegetables (and dairy fat, while decreasing dairy protein) back into my diet. I noticed a ton of 'new' short hairs sprouting at the scalp in the late fall and winter, I was a frizzball. As of yet I only have less than 6" of of thicker regrowth but it seems like my former thickness is returning. Looking forward to growing my hair long again.

It might be a seasonal shedding. Since I went paleo I've noticed I'm more in tune with natural cycles. I start getting tired shortly after sundown and my hair has gotten thinner and lighter in color as summer approaches.

If you have pets you'll see this in action.

This happened to me at the end of last summer, after about three months of paleo eating. During this time, I also gave blood twice (low iron can cause hair loss due to insufficient nutrient delivery to the hair follicles), stopped using shampoo (which can leave the same volume of hair feeling less thick), and lost some weight in spite of actually needing to gain weight. It stopped after about a month and has not been an issue since. I'd probably blame the adaptation to the radical shift in diet and/or the weight loss. I think it's easy to under-consume calories on the paleo diet, and that is metabolic poison for lean people like me and you. Keep your calorie intake and weight up with a lot of saturated fat and good starch, eat some liver if you're worried about low iron (but remember high iron is bad, too), and give this a month or so to resolve on its own before really worrying.

How much D/K2? noticed some hair loss after upping D recently and adding k2. stopping now, hoping it goes away. never had noticeable hair loss until going paleo one year ago. slowly over the last year have lost more and more - some receeding on the forehead, and generally it is thinner all around. considered that it could be low card, magnesium deficiency, too much d.

Creatine can cause shedding and thinning hair. It happened to me. Im a huge advocate for creatine and its results but it does cause hair loss. I was losing lots of hair all of a sudden. Went to the doc and he asked what medications and supplements I was taking. I was only taking whey protein and creatine. He said creatine can starve hair follicles when taken in large doses. I was only taking 3 grams per workout. He recommended I stop taking it if I wanted the thinning to stop. It took about a month for my hair to stop falling out after I stopped creatine. Its slowly starting to thicken up again after 6 months. Prob doesnt do it to everyone but it does happen alot. Im gonna miss it but I like my hair better. The doc said its pretty common complaint with creatine.

I'm 31, I've had a receding hairline for 7+ years now months after eliminating sugar/refined carbs, I've got white fuzz on my bald patch... I'm excited even if it doesn't fill in, it's stopped receding as well, all my hair is growing faster and darker

hair loss can also be caused by creatine supplements, if u take them.

hypothyroid is a possibility

Hi AJ,

Well I am not a doctor, however according to Dr. Loren Cordain who is a professor and author of "The Paleo Diet” the foundation of this diet centers on foods such as lean meat, seafood, fruits, vegetables and nuts that work to support your health and eliminate many of the consequences of unhealthy, modern-day diets. As it relates to hair loss, the Paleo diet claims it can prevent hair loss, specifically male pattern baldness, by controlling a form of the male androgen hormone testosterone called dihydrotestosterone or DHT.

However if you still think it is the main cause of your hair loss it would be good to share your problem personally with an expert as he would be able to suitably guide you. I have been consulting at Forhair clinic for my hair related problems.

Common side effect of low carb diets. It usually takes a month or 2 to start after changing your diet.
