The Role of Nutrition in Lash Health: How Diet Affects Eyelash Growth and Strength

Diet's Impact on Lash Health and Growth

Our diet plays a pivotal role in the health and appearance of our hair, skin, and nails—and our eyelashes are no exception. While lash extensions and serums can enhance the look of our lashes, the foundation of healthy lash growth starts from within. This article delves into how nutrition impacts the health and growth of eyelashes and offers dietary tips to promote stronger, more resilient lashes.

The Basics of Eyelash Growth

Eyelash Growth Cycle

Like the hair on our scalp, eyelashes follow a growth cycle composed of three main phases:

  1. Anagen (Growth Phase): This is the active growth phase where the lash follicle is in the process of producing a new lash. This phase lasts between 30 and 45 days.
  2. Catagen (Transition Phase): During this brief phase, the lash stops growing and the follicle shrinks. This phase lasts for about 2 to 3 weeks.
  3. Telogen (Resting Phase): This is the resting phase where the lash remains in place until it falls out naturally and a new lash begins to grow in its place. The telogen phase can last for 100 days or more.

The health and speed of this cycle can be influenced by various factors, including genetics, age, and—importantly—nutrition.

Key Nutrients for Lash Health

To promote optimal lash health and growth, your diet should include a variety of essential nutrients:

  • Proteins: The building blocks of hair and lashes, proteins are crucial for cell growth and repair.
  • Vitamins: Vitamins like A, C, D, E, and B-complex (especially biotin) play significant roles in maintaining lash health.
  • Minerals: Iron, zinc, and selenium are vital for the overall health and strength of hair, including lashes.
  • Fatty Acids: Omega-3 and Omega-6 fatty acids help in maintaining lash follicle health and reducing inflammation.

Vitamins and Minerals Essential for Lash Health

Biotin (Vitamin B7)

Biotin is often hailed as a powerhouse for hair health. It supports the production of keratin, the protein that makes up hair and eyelashes. Deficiency in biotin can lead to brittle lashes that are prone to breakage.

Sources of Biotin:

  • Eggs
  • Nuts and seeds
  • Sweet potatoes
  • Spinach

Vitamin E

Vitamin E is known for its antioxidant properties that protect the cells of the hair follicles from damage. It helps in improving blood circulation, which is vital for healthy lash growth.

Sources of Vitamin E:

  • Almonds
  • Sunflower seeds
  • Avocados
  • Olive oil

Vitamin C

Vitamin C aids in the production of collagen, a protein that is crucial for hair and lash strength. It also helps in the absorption of iron, another vital nutrient for hair health.

Sources of Vitamin C:

  • Citrus fruits (oranges, lemons, grapefruits)
  • Bell peppers
  • Strawberries
  • Broccoli

Vitamin A

Vitamin A is essential for cell growth, including the cells that make up hair follicles. It also helps in the production of sebum, which keeps the hair and lashes hydrated.

Sources of Vitamin A:

  • Carrots
  • Sweet potatoes
  • Spinach
  • Kale


Iron deficiency can lead to hair loss and weak lashes. Iron helps in carrying oxygen to the hair follicles, promoting healthy growth.

Sources of Iron:

  • Red meat
  • Spinach
  • Lentils
  • Pumpkin seeds

Omega-3 Fatty Acids

Omega-3 fatty acids help to reduce inflammation and promote a healthy scalp and lash line. They also nourish the follicles and keep the lashes strong.

Sources of Omega-3 Fatty Acids:

  • Fatty fish (salmon, mackerel)
  • Flaxseeds
  • Chia seeds
  • Walnuts

Dietary Tips for Healthier Lashes

Incorporate a Balanced Diet

A balanced diet that includes a variety of nutrients is crucial for the overall health of your lashes. Focus on incorporating a mix of proteins, healthy fats, vitamins, and minerals into your daily meals.

Stay Hydrated

Hydration is key to maintaining the health of your hair, skin, and nails, including your eyelashes. Water helps to flush out toxins and keeps the cells hydrated and healthy.

Avoid Nutrient Deficiencies

Certain restrictive diets can lead to nutrient deficiencies that impact lash health. Ensure that your diet includes a variety of foods to prevent deficiencies in key nutrients like iron, zinc, and biotin.

Consider Supplements

If you find it challenging to get all the necessary nutrients from your diet alone, consider taking supplements. Biotin, omega-3 fatty acids, and multivitamins can help fill any gaps in your nutrition and support lash health.

How Diet Impacts Lash Extensions

The Connection Between Nutrition and Lash Extensions

Even if you regularly use lash extensions, your natural lashes' health is still crucial. Healthy, strong natural lashes provide a better foundation for extensions and help them last longer. Poor nutrition can weaken your natural lashes, causing extensions to fall out prematurely or leading to gaps and unevenness.

Pre-Extension Nutrition Tips

Before getting lash extensions, ensure that your diet is rich in nutrients that promote lash health. Focus on consuming foods high in vitamins A, C, and E, as well as biotin and omega-3 fatty acids. This will help to fortify your natural lashes and prepare them for the extensions.

Post-Extension Care

Maintaining a nutritious diet after getting lash extensions is equally important. Proper nutrition helps in the recovery and growth of your natural lashes, ensuring that they remain strong and healthy beneath the extensions.


The health and growth of your eyelashes are intricately linked to your diet. By incorporating a variety of nutrient-rich foods into your meals, you can promote stronger, longer, and healthier lashes. Whether you're maintaining your natural lashes or preparing for extensions, paying attention to your nutrition can make a significant difference in the strength and appearance of your lashes.
