Hair loss in women is more common than you think
Roughly 40% of women experience visible hair thinning by age 50. Yet most suffer in silence, assuming it’s just aging. The truth: many causes are identifiable — and treatable.
1. Female pattern hair loss
Genetic sensitivity to hormones gradually shrinks follicles, most visibly at the part and crown. Early intervention with laser therapy and scalp care can slow or reverse it.
2. Menopause and hormonal shifts
Falling estrogen changes the hair growth cycle. Many women first notice thinning in their late 40s and 50s.
3. Post-partum shedding
Telogen effluvium after pregnancy can cause dramatic shedding 2–4 months after birth. It usually resolves, but scalp care helps recovery.
4. Iron, vitamin D and thyroid
Low ferritin, low vitamin D and thyroid imbalances are frequent contributors. We often recommend asking your physician for bloodwork.
5–7. Stress, tension and medications
Chronic stress, tight hairstyles (traction alopecia) and certain medications can all trigger hair loss. A trichology consult connects the dots.
What to do next
The fastest way to answers is a private scalp analysis. We’ll show you your follicles on screen and build a plan that addresses the cause, not just the symptom.
