Switching to a keto diet can bring amazing benefits—weight loss, better energy, and mental clarity. But some people notice a frustrating side effect: keto hair loss. If you’ve seen more strands in the shower drain, you’re not alone. Let’s break down why this happens and what you can do about it.
Why Am I Losing Hair on Keto?
Hair loss on keto happens for a few main reasons:
Sudden dietary change: Your body needs time to adjust when you cut carbs.
Calorie deficit: Eating too little can trigger hair shedding.
Nutrient deficiencies: Missing key vitamins and minerals can weaken hair.
Stress from ketosis: The transition into ketosis can stress the body, affecting hair growth cycles.
Now, let’s look at these in more detail
Does Not Eating Carbs Affect Hair Health?
Carbs provide quick energy, and dropping them can stress your body. While protein and fats are crucial for hair, some people don’t get enough essential nutrients on keto. If you’re not eating enough calories or missing key vitamins, your hair may suffer.
1. Telogen Effluvium: Temporary Hair Shedding
A sudden diet change, like starting keto, can push hair into a resting phase (telogen effluvium). This causes increased shedding for a few months, but is usually temporary.
“Sudden dietary changes can trigger temporary hair shedding in some individuals.” – PubMed Study on Telogen Effluvium & Diet
2. Nutrient Deficiencies That Cause Hair Loss
Hair thrives on vitamins and minerals. Keto can sometimes lead to low levels of:
Biotin: Essential for hair growth. Found in eggs, nuts, and salmon.
Iron: Low iron can lead to hair shedding. Eat red meat and spinach.
Zinc: Helps with scalp health. Found in beef, pumpkin seeds, and shellfish.
Protein: Hair is made of keratin, which comes from protein. Make sure you eat enough.
“Iron, zinc, and biotin are key for healthy hair.” – Harvard Health on Nutrients for Hair Growth
Fix: Add biotin-rich foods, take a good multivitamin, and eat enough protein.
3. Too Much Stress from Ketosis
Switching to ketosis is a big change. Your body may see it as stress, leading to keto hair loss.
Fix: Try electrolyte supplements, stay hydrated, and ease into keto gradually instead of going ultra-low-carb overnight.

How to Prevent Hair Loss on Keto
Here’s how to keep your hair healthy while staying in ketosis:
1. Eat Enough Calories
Being in a calorie deficit for too long can cause keto hair loss. Make sure you’re eating enough healthy fats and proteins.
2. Increase Protein Intake
Hair needs keratin, and keratin comes from protein. Aim for 0.6-0.8g of protein per pound of body weight.
3. Take Key Supplements
Biotin (Supports hair growth)
Collagen peptides (strengthen hair structure)
Zinc & Iron (Supports scalp health)
Omega-3s (Reduces inflammation)
4. Reduce Stress
Chronic stress affects hair. Try meditation, deep breathing, or gentle exercise.
5. Consider Reintroducing Some Carbs
If your keto hair loss continues, adding low-carb veggies, berries, and nuts might help.
Best Foods for Hair Growth on Keto
Eat these foods to prevent hair loss:
Eggs – Rich in biotin and protein
Salmon – Full of omega-3s
Spinach – High in iron and vitamins
Pumpkin Seeds – Loaded with zinc
Bone Broth – Supports collagen production
Does Keto Hair Loss Stop?
es, keto hair loss is usually temporary. Once your body adjusts, hair should start growing back within a few months. If it persists, check your diet and consult a doctor.
Final Thoughts
Keto hair loss is frustrating but usually temporary. If you’re losing hair on keto, focus on getting enough calories, eating nutrient-rich foods, and managing stress. Your hair should recover in a few months.
