How does postpartum hair loss occur?
Postpartum hair loss occurs due to hormonal changes that take place in a woman's body after giving birth. During pregnancy, increased levels of estrogen prolong the anagen (growth) phase of the hair cycle, resulting in thicker and fuller hair. However, after delivery, estrogen levels drop rapidly, and the hair follicles enter the telogen (resting) phase, leading to hair shedding.
Postpartum hair loss usually starts around two to four months after giving birth, and it can last for up to 12 months. It's a temporary condition and affects up to 50% of women. The amount of hair loss can vary between individuals, with some women experiencing mild shedding, while others may lose more hair. Other factors that can contribute to postpartum hair loss include stress, nutritional deficiencies, and changes in sleep patterns.
