Does Pregnancy Reverse Laser Hair Removal
Does Pregnancy Reverse Laser Hair Removal – Laser hair removal is a popular method for getting rid of unwanted body and facial hair. It works by targeting the hair follicles with pulses of highly concentrated light. This damages the follicles and prevents future hair growth.
Many women undergo laser hair removal prior to getting pregnant. During pregnancy, hormones fluctuate wildly, and sometimes hair that was permanently removed starts to grow back.
This leaves some women wondering if pregnancy can actually reverse the effects of laser hair removal and cause hair to regrow.
How Laser Hair Removal Works
Laser hair removal devices use select wavelengths of light that are absorbed by the melanin pigment in hair follicles. Melanin gives hair its color. The devices remove hair without damaging the surrounding skin.
During treatment, the laser emitter device is placed against the skin. Pulses of intense laser light target and damage individual hair follicles. Most devices use a cooling tip to help protect the outer layers of skin.
Treatments are spaced 4-6 weeks apart because hair follicles cycle through active growth (anagen) and dormancy (telogen) phases.
Repeated treatments ensure that all follicles are turned off during their growth phase. After a series of sessions, most hair stops growing back.
Does Pregnancy Impact Laser Hair Removal?
During pregnancy, hormone levels shift constantly. Estrogen, progesterone, and human chorionic gonadotropin (hCG) are especially elevated. This can stimulate dormant hair follicles and trigger excess hair growth, known as hirsutism.
So why does pregnancy hair growth occur after laser removal treatments? The theory is that follicles weren’t fully destroyed, only weakened and damaged.
Follicles in a borderline state between life and death can remain insensitive to laser light, especially once awakened by pregnancy hormones.
Can Hair Regrow After Laser Removal?
Yes, hair can regrow after laser hair removal, but this is rare. Most patients enjoy permanent hair reduction. However, it’s impossible to turn off 100% of follicles in a given area.
On average, FDA-approved lasers used by trained professionals permanently reduce 70-95% of targeted hair. Less than 30% of follicles may emit subtle regrowth over time. This is normal. Regrowing hairs are typically finer and lighter.
During pregnancy, higher hormone influxes explain why more hairs may unexpectedly return. The good news is that touched-up treatments after giving birth can re-disable unwanted hair.
What Causes Laser Hair Removal to Reverse?
Pregnancy reversal of laser hair removal is temporary. Hair regrowth is linked to hormonal changes, not the ineffectiveness of laser devices.
Common reasons why pregnant women may see old hair return after laser include:
- Borderline-damaged follicles reacting to influxes of estrogen and progesterone.
- Previously dormant follicles reactivate due to the hCG hormone
- Increase in androgens like testosterone during pregnancy
- Improper laser technique leaving follicles alive
- Insufficient energy settings failing to turn off follicles fully
- Natural cycling of hair growth phases
The huge spike in hormones can overwhelm prior laser damage to follicles. This hormone chaos temporarily overrides the long-term impacts of lasers. But most regrowing hairs vanish again after pregnancy.
Can Anagen Reawakening Reverse Hair Removal?
Anagen reawakening refers to the premature activation of hair follicles in the dormant telogen phase into the growing anagen phase. This disrupts the normal hair cycle.
Pregnancy hormones definitely reawaken follicles. High androgen levels during pregnancy also prolong the anagen phase itself. This encourages thicker, rapid hair growth.
These hormonally-stimulated anagen reawakening effects may force damaged hair to grow again after laser removal. The good news is that this hair regrowth after pregnancy tends to be temporary. (Does Pregnancy Reverse Laser Hair Removal)
Does Skin Pigment Impact Post-Pregnancy Regrowth?
Melanin concentration in the skin can influence post-pregnancy hair regrowth odds after laser removal. Patients with darker complexions have higher melanin levels. Laser devices may struggle to turn off follicles under darker or tanned skin fully.
The deployed light wavelengths must successfully penetrate the skin to reach underlying follicles. Darker skin potentially shields follicles.
Lighter skin with lower melanin has higher success rates for long-term laser hair removal. These patients see fewer unwanted hairs return post-pregnancy. However, the hair color itself does not impact results or regrowth. (Does Pregnancy Reverse Laser Hair Removal)
What Areas Are Prone to Post-Pregnancy Regrowth?
Some body areas are more susceptible to post-pregnancy hair regrowth. Androgenic hair triggered by higher testosterone responds most to pregnancy upshifts. These include:
- Facial Hair: Chin, upper lip, cheeks, sideburns
- Body: Chest, abdomen, lower back
- Bikini Zone
- Underarms
- Legs: Thighs, calves
Note that androgenic terminal body hair linked to testosterone activation will react more than vellus hairs. (Does Pregnancy Reverse Laser Hair Removal)
Can Hair Regrow After Laser Hair Removal Years Later?
Years after laser removal treatments conclude, hair has the potential to regrow. However, true reversal after the 2-5 year post-treatment milestone is exceptionally rare when properly performed.
If inadequate laser settings are used or treatments are cut short, the long-term risk of regrowth goes up. But for most patients who complete all suggested sessions, mature follicles stay deactivated for good. (Does Pregnancy Reverse Laser Hair Removal)
The outliers that see stray hairs after many laser-free years usually fall into three categories:
- Never reached full hair removal, only thinning
- Hormonal changes like menopause or pregnancy
- Natural aging drops estrogen/progesterone levels
- Preexisting hormonal imbalance
However, this delayed emergence of new hair remains relatively uncommon with true long-term laser removal. (Does Pregnancy Reverse Laser Hair Removal)
Can Laser Hair Removal Results Be Permanently Reversed?
Full reversal of laser results implies the permanent reactivation of all destroyed hair follicles. This degree of laser failure is highly uncommon years post-treatment.
However, pregnancy hormones have more influence over stimulating dormant follicles than aged follicles. So, post-pregnancy hair could theoretically override some or most laser damage permanently.
In reality, though, pre-pregnancy lasering successfully destroys the vast majority of mature terminal hairs for good. For complete reversal to occur post-pregnancy, prior laser settings must have been inadequate.
The regrowth window after having a baby almost always represents a temporary surge. This includes darker, thicker hairs that laser treatments usually succeed in eliminating for life. (Does Pregnancy Reverse Laser Hair Removal)
Takeaway Points
Pregnancy can prompt temporary regrowth of hair already treated with laser removal. However, full reversal is uncommon.
- Hair that returns due to hormonal influxes post-pregnancy is often finer and lighter.
- Higher estrogen, progesterone, testosterone, and hCG overwhelm prior laser damage to follicles.
- Darker skin with higher melanin concentration has marginally elevated regrowth risk.
- Regions with androgen-sensitive hair are most prone to post-pregnancy recurrence.
- True long-term permanent reversal years later is exceptionally rare.
The bottom line is pregnancy can influence hair follicles previously damaged by lasers. But the complete undoing of laser hair removal is unrealistic years down the road or after just one pregnancy. The hair regrowth window usually closes again postpartum once hormones stabilize. (Does Pregnancy Reverse Laser Hair Removal)
