Phase Theory Beauty Co.™

Pregnancy & Postpartum Phase

Your body is doing something remarkable. Your hair is part of the journey.

Your hair is doing exactly what it is designed to do.

The shedding is temporary and part of your body's return to balance.

Gentle, consistent care is the most powerful tool you have right now.

Your hair is responding to one of the most significant hormonal journeys of your life.

During pregnancy, elevated estrogen extends the active growth phase, often resulting in fuller, thicker hair. After delivery, estrogen levels drop sharply — triggering a wave of shedding known as postpartum telogen effluvium. This typically begins 2–4 months after birth and resolves within 6–12 months. This is not hair loss — it is a natural hormonal transition.

Biological Driver: Estrogen surge during pregnancy → extended anagen phase → postpartum estrogen withdrawal → mass follicle entry into telogen

What You May Notice

Increased shedding after delivery (postpartum telogen effluvium)
