Losing hair can be frustrating and even scary. Hair plays an important role in confidence and overall well-being, so when it starts thinning or falling out, it can feel like something is very wrong. While some shedding is normal, excessive hair loss is often a sign that the body is out of balance. Understanding the root cause can help restore hair health and prevent further thinning.
Common Causes of Hair Loss
• Hormone Imbalances: Hormones play a big role in hair growth. Low thyroid function (hypothyroidism) can slow hair growth and cause thinning, while high androgens (like testosterone) can lead to hair loss, especially in women with PCOS. Estrogen and progesterone changes, such as during menopause or after pregnancy, can also trigger shedding.
• Nutrient Deficiencies: Hair needs vitamins and minerals to grow strong and healthy. Low levels of iron, biotin, zinc, and vitamin D can lead to hair thinning. Not eating enough protein can also weaken hair, making it more prone to falling out.
• High Stress and Cortisol: Chronic stress increases cortisol, which can push hair follicles into a resting phase. This leads to sudden hair shedding, often called telogen effluvium. Stress-related hair loss is common after illness, pregnancy, or major life changes.
• Inflammation and Gut Health: The gut and scalp are closely connected. Inflammation from food sensitivities, gut imbalances, or autoimmune conditions like Hashimoto’s can affect hair growth. A healthy gut supports the absorption of nutrients needed for strong hair.
Tips for Caring for Thinning Hair
• Eat a Nutrient-Dense Diet: Focus on iron-rich foods like leafy greens, healthy fats like avocados, and protein sources like salmon and eggs to support hair growth.
• Manage Stress: Gentle movement, deep breathing, and quality sleep can help reduce cortisol and improve hair health.
• Support Thyroid Health: Checking thyroid levels can uncover imbalances affecting hair growth. A full thyroid panel provides a better picture than a basic TSH test.
• Use Gentle Hair Care Products: Avoid harsh shampoos with sulfates and heat styling, which can damage fragile hair. Look for natural, toxin-free hair products to nourish the scalp.
Hair loss can feel overwhelming, but identifying the root cause can make all the difference. A functional medicine approach looks at hormone levels, nutrient deficiencies, and stress to create a plan for healthier, stronger hair. With the right support, hair can regrow and thrive again.
