Hair loss is a deeply personal and often distressing experience that can affect both men and women. While many factors contribute to hair loss, hormonal imbalances are among the most common and complex causes. Understanding how hormones influence hair growth and loss can provide clarity and direction for addressing this issue.
How Hormones Affect Hair Growth
Hair growth occurs in cycles, with hormones playing a crucial role in regulating these cycles. The main hormones influencing hair health include:
- Androgens: Testosterone and its more potent derivative, dihydrotestosterone (DHT), can shrink hair follicles and shorten the growth phase, leading to androgenic alopecia (pattern baldness).
- Oestrogen: Oestrogen prolongs the hair growth phase, which is why hair often appears fuller during pregnancy. A drop in oestrogen, such as after childbirth or during menopause, can lead to shedding.
- Thyroid Hormones: Thyroid imbalances, whether hyperthyroidism or hypothyroidism, can disrupt hair growth cycles, causing thinning or patchy hair loss.
- Cortisol: Chronic stress elevates cortisol levels, which can disrupt hair growth cycles and contribute to conditions like telogen effluvium.
Common Hormonal Causes of Hair Loss
1. Polycystic Ovary Syndrome (PCOS)
PCOS is a hormonal disorder that affects many women of reproductive age. Elevated androgen levels in PCOS can lead to thinning hair on the scalp (androgenic alopecia) while promoting hair growth in unwanted areas like the face and body.
Signs of PCOS-related Hair Loss:
- Hair thinning or bald spots on the scalp
- Irregular menstrual cycles
- Acne and excess facial or body hair
2. Postpartum Hair Loss
During pregnancy, elevated oestrogen levels keep hair in the growth phase longer, resulting in thicker hair. After childbirth, oestrogen levels drop rapidly, causing many hairs to enter the shedding phase simultaneously.
Signs of Postpartum Hair Loss:
- Noticeable shedding around 3-6 months postpartum
- Hair thinning along the hairline
3. Thyroid Dysfunction
Both underactive (hypothyroidism) and overactive (hyperthyroidism) thyroid conditions can lead to hair loss by disrupting the hair growth cycle and affecting the scalp’s health.
Signs of Thyroid-Related Hair Loss:
- Dry, brittle hair or scalp
- Hair thinning or shedding across the entire scalp
- Other symptoms like fatigue, weight changes, or mood swings
4. Menopause
The hormonal shifts during menopause, particularly the decline in oestrogen and progesterone, can lead to hair thinning. Additionally, relative increases in androgens may exacerbate hair loss.
Signs of Menopause-Related Hair Loss:
- Overall thinning rather than distinct bald patches
- Increased shedding during brushing or washing
How Diet and Lifestyle Can Help Regulate Hormones
Addressing hormonal imbalances naturally requires a multifaceted approach, focusing on diet, lifestyle, and stress management. Here are some strategies to support hormonal health and reduce hair loss:
Nutritional Support
- Protein-Rich Foods: Hair is primarily made of keratin, a protein. Ensure adequate protein intake from sources like eggs, fish, poultry, legumes, and nuts.
- Healthy Fats: Omega-3 fatty acids found in fish, flaxseeds, and walnuts help reduce inflammation and support hormone production.
- Zinc and Iron: Deficiencies in these minerals are linked to hair loss. Include foods like pumpkin seeds, spinach, and lean meats in your diet.
- Biotin and B-Vitamins: Found in eggs, nuts, and whole grains, these vitamins are essential for hair health and hormone regulation.
- Reduce Sugar and Refined Carbs: High sugar intake can worsen insulin resistance, contributing to PCOS and other hormonal imbalances.
Lifestyle Adjustments
- Manage Stress: Chronic stress disrupts hormonal balance. Practices like yoga, meditation, and regular exercise can lower cortisol levels.
- Prioritise Sleep: Hormones reset during deep sleep. Aim for 7-9 hours of quality sleep each night.
- Exercise Regularly: Moderate physical activity helps regulate hormones, improve circulation, and reduce stress.
Targeted Supplementation
- Adaptogens: Adaptogen herbs can help regulate cortisol and support adrenal health.
- Probiotics: A healthy gut supports balanced hormones. Probiotic supplements or fermented foods can improve gut health and hormone regulation.
Signs to Watch Out for and When to Seek Professional Help
Recognising the early signs of hormonal hair loss can help you seek timely intervention. Key signs include:
- Sudden or excessive hair shedding
- Thinning hair on the crown or along the hairline
- Bald patches or widening part lines
- Symptoms of hormonal imbalances like acne, irregular periods, or unexplained fatigue
If you suspect hormonal imbalances are contributing to your hair loss, consulting a naturopath is essential. Functional testing, such as hormone assessments or thyroid panels, can pinpoint the root cause and guide targeted treatment.
