6 Common Causes of Hair Loss — Could TCM Be Right About the Root Issue?

Hair loss can be attributed to both genetic and lifestyle factors. However, many women tend to seek quick-fix solutions instead of identifying the actual cause, often leading to disappointing results. To truly resolve hair loss issues, it's important to first understand what’s behind them. Below are six common causes:

1. Traditional Chinese Medicine: Deficiency in Qi, Blood, and Kidney Essence

According to Traditional Chinese Medicine (TCM), “The liver stores blood, and hair is its surplus. Hair loss signifies depleted blood.” In this philosophy, the liver acts as the body's "blood bank," and hair is a direct reflection of blood health. Another saying goes, “The kidneys store essence, govern bones, and their essence is reflected in the hair.” This means kidney health is tied to hair vitality and appearance. People with strong Qi, blood, and kidney essence typically have thicker, darker hair, while those with deficiencies may experience premature graying and hair loss.

2. Excessive Use of Chemicals

Chemical treatments such as bleaching, dyeing, and perming can damage the hair cuticle, weakening its ability to retain moisture. Overuse of harsh chemicals may also harm the scalp and follicles, leading to hair breakage or even alopecia.

3. Using the Wrong Hair Products

Even without frequent styling, hair loss may stem from inappropriate shampoo and conditioner choices. Incomplete rinsing, overly rich formulas, or products loaded with silicones can clog hair follicles, leading to hair issues. It's crucial to choose the right products for your scalp and hair type and to wash your hair properly.

4. Stress

Women typically experience diffuse hair thinning on the top, hairline, or sides of the head, rather than the balding patterns seen in men. Even celebrities aren't immune — Blackpink’s Lisa has a notably high hairline, and Park Eun-ji shared on KBS’s “Human Condition” that stress caused her hair to fall out. These are common signs of stress-related hair loss among modern urban women, often linked to hectic lifestyles and poor habits.

5. Illness

Many assume that hair loss only affects the chronically ill or middle-aged. However, during the height of the pandemic, even young women reported significant hair shedding following illness. Recently, even the beloved Vivian Chow openly admitted to temporary hair loss after recovering from illness.

6. Nutritional Deficiencies

A lack of key nutrients like iron and protein can make hair brittle and prone to breakage, while insufficient vitamins and minerals can trigger hair fall. Extreme diets or imbalanced nutrition can interfere with healthy hair growth. To protect hair health, a balanced diet rich in essential nutrients is key. If you're unsure whether your hair loss is linked to nutritional deficiencies, consult a doctor or dietitian.

Vitamins for Women with Hair Loss: What Is Biotin? 7 Must-Know Hair-Healthy Nutrients

Many women focus heavily on choosing the right shampoo or hair tonic when dealing with hair loss, but the real game changer may lie in nourishing your body from the inside out. Specific vitamins are vital for strengthening hair strands, supporting growth, and reducing hair loss. Here are seven essential vitamins that play a critical role in hair health:

1. Biotin (Vitamin B7/H)

One of the most popular hair nutrients, biotin helps strengthen hair structure, prevent brittleness, and promote healthy growth. It also supports energy conversion from food and benefits nails and skin. A deficiency in biotin can directly result in hair thinning or loss.

2. Vitamin A

This fat-soluble vitamin promotes healthy hair follicles and supports the scalp’s natural oil production, which prevents dryness and breakage. It also helps maintain a healthy scalp environment for strong hair growth. However, too much vitamin A can worsen hair loss, so balance is key. Natural sources include carrots, bell peppers, leafy greens, liver, and eggs.

3. Vitamin C

A powerful antioxidant, vitamin C is essential for collagen production, which improves hair texture and elasticity. It also protects against oxidative stress and enhances scalp health. A lack of collagen can lead to breakage, split ends, and brittle nails. Ensure sufficient intake through diet or supplements.

4. Vitamin D

Vitamin D supports healthy hair growth and regulates calcium absorption, which is crucial for proper follicle function. It also helps relieve dry, itchy scalp conditions. Moderate sun exposure and vitamin D-rich foods are the best ways to meet your needs.

5. Vitamin E

This antioxidant improves blood circulation in the scalp and supports shiny, healthy-looking hair. It also balances oil production and helps prevent split ends. Natural sources include corn, peanuts, olives, and soy. Supplements are also available but should be taken under medical advice.

6. Vitamin B Complex

This group includes B1, B2, B3 (niacin), B5, B6, and B12, each with unique benefits. For instance:

• B1 and B2 support healthy hair structure.
• Niacin (B3) improves scalp circulation and may delay graying.
• B5 and B6 strengthen the hair shaft and encourage growth.
• B12 is vital for red blood cell production and supports overall hair health.

7. Folic Acid (Vitamin B9)

Folic acid helps with cell renewal, essential for new hair growth. It also supports scalp health, reduces dryness, and creates a favorable environment for growing hair. It’s commonly found in leafy greens, legumes, whole grains, eggs, and liver.

Bonus Nutrients for Hair Health

Beyond vitamins, certain minerals and nutrients are crucial for maintaining strong, healthy hair:

• Iron: Supports red blood cell production and nutrient delivery to follicles. A deficiency is often an early sign of hair loss.
• Zinc: A trace mineral that promotes growth and helps prevent hair loss. However, excessive zinc can backfire.
• Copper: Maintains hair color and texture.
• Selenium: Antioxidant that protects against follicle damage.
• Protein: Hair is primarily made of protein, making it essential for strength and elasticity.
• Omega-3 Fatty Acids: Nourish the hair and promote shine.
• Silica: Reinforces hair structure.
• Collagen: Improves elasticity and texture.

Since hair loss causes vary from person to person, it’s best to consult a healthcare provider before starting supplements to find the most appropriate solution for your needs.
