Pregnancy and the months that follow bring some of the most dramatic hormonal shifts a body experiences, and hair growth is far from immune. Understanding the pattern helps you time hair removal decisions instead of being caught off guard by them.
During Pregnancy: Why Hair Often Grows Thicker
Elevated estrogen during pregnancy extends the anagen (active growth) phase of the hair cycle, meaning fewer hairs shed into the resting phase than normal. The practical effect many people notice is thicker-seeming hair, both on the scalp and on the body, since more hair is staying in active growth simultaneously rather than cycling out.
Hair removal safety during pregnancy: Shaving, waxing, epilation, and depilatory creams are all generally considered safe during pregnancy, though skin can be more sensitive, making a patch test for depilatory creams more important than usual. IPL and laser hair removal are more commonly advised against during pregnancy — not because of documented harm, but because it hasn't been adequately studied in pregnant populations, and most manufacturers explicitly exclude pregnancy from their safe-use guidance as a precaution.
The Postpartum Shed
Around 2-4 months after delivery, the extended anagen phase ends and a large proportion of hair that was "held" in active growth during pregnancy shifts into the shedding phase simultaneously — commonly called postpartum shedding or telogen effluvium. This is most noticeable on the scalp (leading to the well-known postpartum hair loss many new parents experience) but affects body hair growth cycles too.
What this means for hair removal timing: Because a significant portion of body hair may be mid-shed during this window, starting or resuming an IPL treatment course during the peak postpartum shedding period (roughly months 2-5 postpartum) may produce less consistent results than waiting for hair growth cycles to restabilize, typically by 6-12 months postpartum for most people.
Breastfeeding and IPL
Similar to pregnancy, most home IPL manufacturers advise against use while breastfeeding, again as a precaution based on limited safety data in this population rather than documented risk. If you're breastfeeding and want to resume IPL treatment, waxing, epilation, and shaving remain available options in the meantime, or consult your healthcare provider about your specific situation.
Skin Sensitivity Changes
Hormonal shifts postpartum can also affect skin sensitivity and healing, sometimes making skin more reactive to hair removal methods than it was pre-pregnancy, even temporarily. Starting any hair removal method — including ones you used consistently before pregnancy — at a lower intensity or with an extra patch test is a reasonable precaution during the first several months postpartum.
When to Resume a Full Routine
Most of the hormonal disruption to hair growth cycles has resolved by 6-12 months postpartum for most people, though timelines vary individually and can be extended by continued breastfeeding. If you paused an IPL treatment course during pregnancy or breastfeeding, resuming with a fresh patch test — treating it similarly to starting with a new device — is a reasonable approach given how much your hormonal environment and skin sensitivity may have shifted in the interim.
Bottom Line
Pregnancy hormones commonly thicken visible body hair by extending the growth cycle, followed by a postpartum shedding phase a few months after delivery. Most hair removal methods remain available during pregnancy and postpartum, with IPL and laser being the exceptions most commonly paused as a precaution — plan to resume those once you're done breastfeeding and consult your healthcare provider with any specific concerns.
