The ketogenic diet, commonly known as keto, has become immensely popular in recent years as a rapid weight loss solution. With its emphasis on high-fat and low-carb intake, keto has proven benefits for dropping pounds quickly. However, this restrictive diet plan also comes with potential side effects. One concerning issue posed by keto devotees is: does this diet lead to increased hair loss?
Significant hair loss can occur with any major shift in diet, but particularly with restrictive diets low in essential nutrients. As keto limits carbohydrate intake drastically, it puts dieters at risk for deficiencies in vitamins, minerals, protein, and calories needed for healthy hair growth.
In this guide, we’ll help you understand the mechanisms and factors behind keto hair loss and what you can do to maintain healthy hair growth while following a ketogenic diet. With the right dietary adjustments and supplements, you can reap the benefits of keto without the unwanted thinning of your head of hair.
We know it can be worrying to see changes in your hair health when you start a keto diet. It’s common for hair growth to be affected initially, but this is often a temporary phase. Losing weight quickly because of eating fewer carbs can make more hair start to fall out. However, keto proponents note this increased hair loss is often temporary. As the body adapts to using fat for energy, hair growth may return to normal. However, other factors, like nutritional deficits, can have longer-lasting effects.
The ketogenic diet is characterised by an extreme reduction in carbohydrate intake, typically limiting carbs to just 50 grams or less per day. This very low intake of carbohydrates puts the body into ketosis, meaning it switches to burning fat as the primary source of energy instead of carbs.
When you eat fewer carbs, your body starts to use fat for energy instead. It turns this fat into substances called fatty acids and ketone bodies, which then provide energy for your brain and other organs. This metabolic state of ketosis is the goal of keto diets.
When beginning a ketogenic diet, it’s normal to experience sudden hair loss as the body adjusts. But the good news is that it’s only temporary in most cases. This temporary phase of increased shedding can last around 2-3 months. It reflects the normal hair growth cycle being altered due to the metabolic changes of ketosis.
The anagen phase, where hair actively grows, is typically 3-10 years. This is followed by a short 2-3 week telogen or resting phase before hair sheds. However, changes in your diet and potential deficiencies can shorten the growth phase of some hair, leading to more hair entering the shedding phase at the same time. This results in noticeable hair loss, but new growth usually resumes once ketosis adaptations are complete.
However, there are caveats to this temporary hair loss pattern. Extreme calorie restriction, nutritional deficits, and high stress levels can prolong keto-related hair thinning. The key is taking steps to mitigate these risks and support healthy hair regrowth.
While temporary hair loss can occur when first entering ketosis, nutritional deficiencies likely play a larger role in prolonged keto-related shedding. The dietary restrictions inherent to ketogenic diets limit many foods that provide key nutrients to support healthy hair growth.
Getting enough protein is very important for healthy hair because hair is mostly made of a protein called keratin. However, many protein-rich food sources like beans, lentils, and grains are restricted to very low-carb ketogenic diets.
We understand the goal of rapid weight loss on keto, but it’s important to be mindful that very low calorie intake can reduce protein levels, which are crucial for your hair’s health. Consuming insufficient calories and protein puts the body into survival mode, diverting energy away from non-vital functions like new hair growth.
Hair roots need a constant supply of building blocks from proteins in your diet to keep growing. Chronic protein deficiency can contribute to hair loss by prematurely pushing more follicles into the telogen resting phase.
Experts recommend consuming at least 0.8 grams of protein per kilogram of body weight, which equals to 45-55.5 grams of protein daily for the hair health of most adults, more for active individuals. Very low-calorie ketogenic diets often fall short, lacking adequate high-quality protein sources like fatty fish, eggs, meat, dairy and plant-based proteins.
In addition to sufficient protein and calories, a variety of essential vitamins and minerals are required to sustain healthy hair growth cycles. Many of these key micronutrients are found in fruits, starchy vegetables, beans and grains, which are restricted on ketogenic diets.
Biotin is one of the most important vitamins for hair health. This B vitamin helps produce keratin and keeps hair follicles healthy. Deficiency can lead to brittle, thinning hair. Ketogenic dieters are at risk for inadequate biotin intake with the elimination of good sources like whole grains and legumes.
The mineral iron also enables healthy hair growth by carrying oxygen to follicles. Iron deficiency is common even in non-keto diets and is further worsened by a lack of iron-rich foods like spinach, lentils and fortified cereals. Low iron can accelerate hair shedding.
Other key hair-supporting micronutrients often lacking in keto diets include zinc, folic acid, and vitamins A, C, D and B-complex. Assessing where nutritional shortfalls may exist can help counter hair loss.
When transitioning to a ketogenic diet, being aware of the signs of potential hair loss can help you identify and address issues early. Here are some symptoms to watch for:
Being vigilant about any of these symptoms and taking prompt action to adjust your keto diet and hair care regimen helps mitigate hair loss.
In addition to nutritional deficits, high-stress levels can exacerbate hair shedding for keto adherents.
Stress affects hair growth and shedding through various pathways. Emotional and psychological stress releases hormones that disrupt the normal hair cycle. Physical stressors like dietary changes, illness or calorie restriction can have similar effects.
Sudden weight loss is a physical stressor tied to accelerated hair loss. The ketogenic diet’s dramatic carbohydrate restriction and transitions into ketosis act as significant physical stressors on the body. The hormonal effects of this stress can shift more hair into the shedding phase.
We know how challenging stress management can be, but finding ways to reduce stress is important for both your overall well-being and for maintaining healthy hair growth. Techniques like meditation, exercise, social connection, and adequate sleep help counter stress hormone effects. For keto dieters, slowly transitioning into very low-carb eating may further minimise stress.
It’s important to recognise that starting a ketogenic diet is a big change for your body and can be stressful. We’re here to support you in making this transition as smooth as possible. Strategies like mindful carb reduction and adding certain keto-friendly foods can help minimise hair-damaging effects.
Gradually decreasing carbohydrates over several weeks allows the body to slowly adapt to using fat for fuel. This less drastic transition into ketosis reduces the sudden stress of quick carb restriction.
Adding foods like fatty fish, eggs, bone broth, and green vegetables provides more protein, vitamins, minerals and fluids to counter nutritional deficits. Tailoring the keto diet to meet micronutrient needs supports hair health.
The ketogenic diet can be adapted and supplemented to support continued hair growth instead of increased shedding. With careful nutrition and hair care, it is possible to reap keto benefits without compromising locks.
To maintain shiny, healthy hair on keto, ensure adequate intake of protein and calories. Hair is over 90% protein, requiring a steady supply of amino acids for growth. Experts recommend consuming at least 0.8 grams of high-quality protein per kilogram of body weight daily. Increase protein slightly with exercise.
Great protein sources on keto include fatty fish like salmon, pasture-raised eggs, bone broth, nuts, seeds, and low-carb dairy products. Try incorporating collagen peptides, which provide the amino acids cysteine, proline and lysine vital for hair keratin.
Do not restrict calories excessively, as this stresses hair follicles. Aim for a modest 20-30% calorie reduction from maintenance needs for gradual weight loss. Adding calorie-dense foods like olive oil, nuts, seeds, and avocados helps prevent deficits.
Nutritional supplements can help fill gaps in vitamins, minerals and amino acids that may arise from ketogenic diet restrictions. Key supplements for hair health include:
In addition to supplements, treatments like Finasteride (Propecia), Regaine, and Regaine for Women can help stimulate hair growth in androgenetic alopecia or pattern baldness. Finasteride is an oral medication that blocks DHT, the hormone that causes hair follicles to shrink. Regaine and Regaine for Women contain minoxidil, which improves blood flow and nutrient delivery to follicles. Using these treatments together with supplements provides both internal and external support for robust hair growth.
Using hair care products on your scalp along with taking supplements can give better results. Caffeine shampoos like Alpecin Caffeine Shampoo or Alpecin Double Effect extend the time hair remains in the anagen growth phase. Scalp massage serums with peptides improve follicle circulation and nutrient delivery for healthier hair growth.
Seeking professional guidance helps customise the ideal supplement and hair care regimen for your situation. This combines the right internal and external solutions for robust hair on a ketogenic diet.
When starting a ketogenic diet, it’s important to customise it based on your individual needs for optimal hair health. Use a macro calculator first to determine your daily protein, fat and carb needs, considering factors like age, gender, activity level and weight. This provides personalised macros to achieve ketosis without excessive restriction.
Incorporating nutritious foods like fatty fish, nuts, seeds, greens, eggs, dairy, and berries provides key hair nutrients. You may also strategically time carb intake around workouts to fuel activity. Consider your lifestyle and preferences when customising your keto diet for easy adherence and hair support.
If you notice signs like increased shedding or thinning, it’s a gentle reminder from your body to reassess your diet. We’re here to help guide you through making any necessary adjustments. Proactively adding more protein, calories or targeted supplements can address deficits before they worsen.
Regularly weigh yourself and recheck macro targets and caloric intake to ensure you aren’t overly restricting. Periodic “keto resets” - short periods boosting calories, carbs and protein - help replenish the body and counter metabolic slowdowns.
Tests like amino acid or vitamin level assessments provide objective data to fine-tune your keto diet for optimal hair growth. Seek professional guidance on correctly interpreting results. Careful customising and monitoring are key for hair health on keto.

Getting through those first few days can be a real challenge! Headaches, fatigue, cravings, and brain fog are super common as your body transitions into ketosis. Stick with it by staying hydrated, getting enough sleep, and knowing it’ll pass.
In most cases, yes! The initial shedding that many experience when starting keto is usually temporary as your body adjusts. Tweaking your diet to get the protein and nutrients you need, keeping stress in check, and using supplements and hair-friendly products will typically help hair regrow once you’re keto-adapted.
It varies, but many find the increased shedding lasts around 2-3 months as their body gets used to ketosis. Taking proactive steps to support hair health can shorten this adjustment phase. But chronic restrictive dieting and nutritional shortfalls can draw it out.
Load up on protein-rich foods like fatty fish, eggs, nuts, seeds, leafy greens, avocados, berries and yoghurt. Also aim for foods with iron, biotin, vitamins A, C and D, zinc and omega-3s. All superstar nutrients for strong hair!
Limit foods with refined carbs, added sugars, processed oils and unhealthy fats - they can promote shedding. Also go easy on alcohol, fried food, high-sodium eats and caffeinated drinks which can aggravate hair loss.
