Understanding Hair Health with PCOS
Polycystic Ovary Syndrome (PCOS) significantly impacts hair health due to hormonal imbalances, particularly elevated androgen levels (like testosterone), affecting 40% to 70% of women with the condition. This often results in a "double effect" where women experience excess hair growth (hirsutism) on the face and body while simultaneously experiencing hair thinning or loss on the scalp.
1. Elevated Androgens (Male Hormones)
PCOS often causes higher levels of androgens such as testosterone.
Effects on hair:
Triggers coarse, dark hair growth on the face, chin, upper lip, chest, abdomen, and back (known as hirsutism)
Causes scalp hair follicles to shrink, leading to thinning hair and increased hair fall, particularly around the crown and temples
The same hormones stimulate hair growth in unwanted areas while weakening hair on the scalp.
2. Insulin Resistance
Insulin resistance is common in PCOS, even in individuals with a healthy body weight.
How it affects hair:
High insulin levels increase androgen production in the ovaries
Worsens facial and body hair growth
Disrupts the scalp hair growth cycle, causing excessive shedding and thinning
Managing insulin levels is crucial for improving PCOS-related hair concerns.
3. Hormonal Imbalance and Irregular Ovulation
Irregular or absent ovulation in PCOS leads to lower progesterone levels.
Impact on hair health:
Creates estrogen dominance
Reduces the body’s natural ability to balance androgen activity
Allows androgen-related hair symptoms to become more pronounced
4. Increased Sensitivity of Hair Follicles
Some individuals with PCOS are genetically more sensitive to androgens.
What this means:
Facial and body hair follicles overreact, producing thicker hair
Scalp hair follicles become more vulnerable and shrink faster, leading to thinning
This explains why hair symptoms vary greatly among people with PCOS.
5. Chronic Inflammation
PCOS is associated with low-grade chronic inflammation.
Effects on hair:
Weakens scalp hair follicles
Disrupts normal hair growth cycles
Makes hair more prone to breakage and shedding
Inflammation can worsen both hair loss and excess hair growth.
6. Stress and Elevated Cortisol Levels
Chronic stress increases cortisol, the stress hormone.
How stress contributes:
Aggravates insulin resistance
Increases androgen activity
Pushes scalp hair into the shedding phase, resulting in noticeable hair loss
Stress management plays an important role in supporting hair health in PCOS.
7. Nutrient Deficiencies Common in PCOS
People with PCOS often experience deficiencies in key nutrients such as:
Iron
Vitamin D
Zinc
B-complex vitamins
These nutrients are essential for healthy hair growth, and deficiencies can accelerate hair thinning and hair loss.
Conclusion
Excess facial and body hair along with scalp hair thinning in PCOS is caused by a combination of:
Hormonal imbalance
Elevated androgens
Insulin resistance
Inflammation
Stress
Nutrient deficiencies
Addressing the root causes rather than relying solely on cosmetic treatments is essential for long-term improvement in PCOS-related hair issues.
