Dieting and Hair loss


Drastic Calorie Reduction:

Studies have shown that significant weight loss causes hair loss. When calories are reduced dramatically, your body uses its energy on vital systems, rather than hair growth. In short, fewer calories = less energy to go around.

 Telogen Effluvium:

Big diet changes can throw you into a common condition called Telogen Effluvium, which means you’ll shed a lot of hair for 2-3 months. It’s temporary in most cases, although very alarming! Once your body gets over the shock, it should adapt, and your hair cycle will get back on track.

 Nutritional Deficiencies:

When starting a low carb diet, many people forget that they’ll need to replace the vitamins and minerals they’re losing. Your kidneys may flush out electrolytes your body needs like zinc, magnesium, sodium, potassium, and iodine. Replacing electrolytes on keto is essential to feeling your best.


A Biotin deficiency could be another culprit. Biotin helps convert food into energy, and some studies show that a lack of Biotin can cause hair loss. Start with 1,000 – 2,500 mg of Biotin daily.


Does stress ever not play a role? When starting a restrictive diet, your body will undergo all kinds of new stress. It can cause temporary hair loss (Telogen Effluvium) or even Alopecia Areata (large clumps of hair falling out). Try to limit stress in other ways if you can.

 Underlying Medical Condition:

If you have tried many methods of stopping hair loss on keto, you may want to talk to a doctor to rule out a medical condition that might be contributing.

First Steps:

Add the following products to your daily diet – Collagen, and Biotin. Collagen is our body’s main structural protein and is vital to hair and nail growth. Supplementing with it can only help! Biotin has also been shown in studies to effectively stop hair loss.

Next Steps to supplement keto hair loss:

Zinc – Zinc promotes good thyroid function and stimulates the hair growth repair cycle. You can find a good supplement, or get these from Pumpkin Seeds (or Pepitas)!

Caffeine – Studies show caffeine can help spur on hair growth.

Essential Oils – Peppermint Oil applied to the scalp has been shown to quickly induce the Anagen stage. Lavender, Rosemary, Cedarwood, and Sage have also shown positive results. (Some studies show Rosemary to be as effective as Minoxidil!)

Hydrate: To help keep the hair you have, hydrate it well so it will be less brittle. Try to drink at least half your body weight in water ounces. (So if you are 150 lbs, drink 75 ounces.)

Coconut Oil – Stimulate your scalp by massaging in coconut oil before a shower. Be gentle so as not to rip out any hair, but this should moisturize your scalp to make it more healthy.
