Hormones and Hair Growth: The Connection

The Hormone-Hair Connection

Hair follicles are remarkably sensitive to hormones. When hormones are balanced, hair tends to grow in healthy cycles. When they shift — during perimenopause, menopause, postpartum, or with conditions like PCOS and thyroid disease — hair growth can be disrupted.

Key Hormones That Affect Hair

• Estrogen: Generally supports the growth phase of hair. Declining estrogen during perimenopause and menopause can contribute to thinning.
• Progesterone: Works in balance with estrogen; imbalances may influence hair health.
• Testosterone and DHT: In susceptible individuals, DHT can shrink hair follicles and contribute to thinning.
• Thyroid hormones: Both low and high thyroid function can cause hair shedding.
• Cortisol: Chronic stress and elevated cortisol can push hair into a shedding phase.
• Insulin: Insulin resistance, common in PCOS, can influence androgen activity and hair health.

How Hormonal Imbalances Show Up

Hormonal hair loss can look like diffuse thinning, a widening part, increased shedding, or changes in hair texture. Because these symptoms overlap with other causes, testing is essential to understand what is really happening.

Evaluating Your Hormones

Dr. Masghati uses comprehensive hormone evaluation — looking at estrogen, progesterone, testosterone, DHEA, thyroid markers, cortisol, and insulin — to build a complete picture. This informs an individualized plan that may include hormone optimization alongside regenerative and nutritional strategies.

Restoring Balance to Support Hair

When hormonal imbalances are identified and addressed, many women see improvements not only in their hair but in energy, mood, and overall wellbeing. A consultation is the first step toward understanding your unique hormonal picture.
