Causes: 

• Hormonal fluctuations: After giving birth, levels of estrogen and progesterone drop significantly, which can lead to hair follicles entering a resting phase. 

• Increased hair shedding: This resting phase results in an increased number of hairs being shed simultaneously. 

Symptoms: 

• Excessive hair loss, often in clumps

• Thinning hair

• Scalp may feel tender or itchy 

Onset and Duration: 

Postpartum alopecia usually begins 2-5 months after giving birth and peaks around 4-6 months. It typically lasts for 6-12 months, but may resolve sooner or later in some women.
