Experiencing hair fall or breakage can be deeply frustrating, and while external factors like hair products and environmental stressors often take the blame, the root cause may lie deeper within your body.
Your hair health is closely tied to your overall well-being, and internal health issues, especially hormonal imbalances, play a significant role in how your hair behaves. For women, this is even more pronounced, as fluctuations in hormones can cause noticeable changes in hair growth, texture, and density.
Let’s take a closer look at the internal health issues that could be contributing to your hair breakage and thinning.
Hormonal Imbalance and Hair Health
Hormones are powerful agents in regulating hair growth and quality. Fluctuations in hormones can lead to hair thinning, excessive fall, or breakage. Some key hormones play a direct role in hair health, including:
Estrogen and Progesterone: These hormones, particularly in women, are central to maintaining strong, healthy hair. “The higher the estrogen and progesterone levels, the greater the hair growth,” says Dr. Nirupama Parwanda, a dermatologist and founder of Zolie Skin Clinic. They support the hair growth phase and prevent premature shedding. However, during menopause, when estrogen and progesterone levels drop, women often experience significant hair thinning.
Testosterone, Androgens, and DHT
While testosterone is often thought of as a male hormone, women produce it in smaller amounts as well. Elevated levels of testosterone, as seen in conditions like Polycystic Ovary Syndrome (PCOS), can cause hair loss and thinning. Dihydrotestosterone (DHT), a derivative of testosterone, further exacerbates hair loss by shortening the hair growth phase. Women experiencing irregular periods or acne should consider getting checked for PCOS.
Thyroid Health and Hair Loss
Thyroid hormones are critical in regulating the development of hair follicles. When the thyroid gland is underactive (hypothyroidism) or overactive (hyperthyroidism), it can disrupt hair growth, leading to thinning and excessive shedding. “Thyroid hormones are essential for overall health, including hair growth,” says Dr. Kashish Kalra, MD, Dermatologist and Hair Transplant Surgeon. Routine thyroid checks can ensure that your levels are balanced and that your hair health is protected.
Cortisol and Hair Growth
Stress may not just affect your mental health—it can also directly impact your hair. Cortisol, the stress hormone, can severely inhibit hair growth. High cortisol levels disrupt the normal hair growth cycle, leading to hair loss. “The higher the cortisol levels, the lower the hair growth,” says Dr. Kalra. Stress-induced hair loss can be particularly challenging because it affects hair follicle stem cells, leading to increased shedding.
Nutrient Deficiencies and Hair Health
While not hormones, vitamins play an important role in maintaining hair strength and quality. Deficiencies in essential vitamins like Vitamin D3, B12, iron, and zinc can contribute to hair thinning and breakage. It’s vital to monitor these nutrients and maintain a balanced diet to support optimal hair growth.
Diabetes and Insulin Resistance
Conditions like diabetes and insulin resistance have long-term effects on hair health. High blood sugar levels can negatively affect hair follicles, leading to shedding and thinning. Additionally, insulin resistance can heighten the risk of developing PCOS, further worsening hair thinning. Managing blood sugar and improving insulin sensitivity can help improve overall hair health.
Lifestyle changes, including managing stress, improving your diet, and ensuring adequate nutrient intake, are crucial in maintaining hormonal balance. By addressing internal health issues, you can promote better hair growth and reduce the risk of hair breakage. If you’re experiencing excessive hair loss or breakage, it’s important to consult a healthcare provider to assess any underlying issues and create a tailored plan for recovery.
