Hormones are key regulators of nearly every function in our body, including how and when our hair turns grey. While greying hair is often seen as a natural sign of aging, it's actually influenced by complex hormonal shifts—and these changes often show up differently in men and women. For those with textured or curly grey hair, understanding this impact is the first step to healthier, more vibrant strands.

Hormonal Effects in Men

In men, testosterone and related androgens play a central role in hair behavior. Although testosterone doesn't directly cause hair to turn grey, its hormonal byproducts can weaken follicles, speeding up the greying process. Additionally, as testosterone levels gradually decline during andropause, melanocyte activity—the pigment-producing cells—can also diminish, leaving strands without color.

• Testosterone and Androgens: These hormones can affect the structure and strength of hair follicles, making grays more prominent.
• Pattern Baldness: Hormone-driven hair thinning can make greying hair more visible.
• Andropause: The male equivalent of menopause involves a drop in testosterone, which may signal changes in pigment production.

Hormonal Effects in Women

For women, estrogen and progesterone help support hair growth, thickness, and pigmentation. During menopause and other hormonal transitions such as postpartum recovery, the sudden impression of grey hair can be as unexpected as it is frustrating. Estrogen in particular has a known influence on melanocyte health, making its decline one of the key factors in greying.

• Estrogen: Supports melanin levels and hair growth; its reduction can accelerate greying.
• Progesterone: Plays a less understood but contributing role in the hair aging process.
• Menopause & Postpartum: Significant hormonal shifts can lead to both hair thinning and greying.

Other Causes of Greying Hair

While hormones hold significant power in the greying timeline, your genes, stress levels, and even your diet play crucial roles. Chronic stress releases hormones that can dampen melanin production, and nutritional deficiencies in minerals like copper and iron can trigger premature greying. Genetic predisposition, however, remains one of the strongest factors—so if your parents went grey at 35, chances are you might too.

Whether you're navigating hormonal changes or simply looking to enhance the beauty of your natural greys, understanding these drivers allows you to care for your hair with intention and pride.
