What’s Really Causing Hair Thinning After 35 (And What Isn’t)

Hair thinning after 35 is often explained away with one phrase: “It’s just age.” In reality, the cause is usually more nuanced and far more manageable than that.

For many women, thinning is the result of multiple overlapping factors, not a single issue. Hormonal shifts during perimenopause and menopause can shorten the hair’s growth cycle, leading to increased shedding or slower regrowth. Postpartum recovery, thyroid changes, nutritional depletion, chronic stress, illness, and certain medications can all contribute as well.

What’s important to understand is that hair thinning is rarely sudden. It’s cumulative. And because it happens gradually, many women second-guess themselves before seeking guidance.

Just as important is knowing what isn’t typically the primary cause of thinning:

• Washing your hair too often

• Occasional heat styling

• Wearing extensions when they are selected and installed correctly

Fear-based information keeps women stuck. Education creates clarity.

Not all thinning looks the same. Some women notice diffuse shedding throughout the scalp. Others experience changes at the temples, crown, or part line. Each pattern tells a different story and requires a different approach.

This is why personalized consultations matter. There is no one-size-fits-all solution. Some clients benefit from internal support and lifestyle adjustments. Others need strategic haircut design, targeted treatments, or subtle enhancement to restore balance and confidence.

The most effective hair solutions are rarely extreme. They’re intentional. They respect the hair you have while supporting the hair you want to maintain.

Understanding the cause is the foundation. Choosing the right path forward comes next.
