Laser hair removal is often touted as a safe, effective, and permanent method to get rid of unwanted body and facial hair. However, the hard truth is that laser hair removal sometimes does not work for everyone.
In this guide, Dr. Soni, Ethos Aesthetics & Wellness’ medical director, will share insights on reasons why laser hair treatment may not work.
The effectiveness of laser hair reduction depends on individualized treatment parameters, including skin type, hair type and color, hair growth cycle, and the presence of a tan.
While most patients can experience up to 90% long-term reduction in hair growth after a series of treatments, these can prevent a minority of patients from seeing similar results.
So why might laser hair removal fail for some people?
Laser hair removal works by targeting the melanin pigment in hair follicles with quick pulses of intense laser light. This laser energy gets absorbed by the dark pigment, heating up the follicle and damaging it to prevent future hair growth.
So for the treatment to work, there needs to be high contrast between the color of the hair and the color of the skin.
The ideal candidates have very fair skin and noticeably darker coarse hair. If the hair color is too light such as white, gray, blonde or red, the laser will not be able to effectively target the weaker melanin pigment in those follicles.
Recent advancements in laser hair removal devices using longer wavelengths can better treat those with darker skin tones, but lighter hair continues to pose a challenge.
Another factor impacting results is the natural hair growth cycle of the body area being treated. As outlined by Dr. Soni, each hair follicle goes through three distinct phases:
Laser hair removal only damages hair follicles that are currently in the active anagen growth phase. Follicles in the other phases will be missed and will need to be targeted in future treatments as they re-enter anagen.
If treatments are not timed properly based on the area’s specific growth cycle, they may fail to disable enough hair follicles to produce a noticeable reduction in hair growth.
For those suffering from excess hair growth on the face or body, especially women, Dr. Soni points out that the culprit could be an undiagnosed hormonal imbalance throwing off the hair growth cycle.
Common hormonal conditions leading to unwanted hair growth include:
For women with hormonal imbalances like PCOS, laser hair removal can work to an extent by damaging the overactive hair follicles. However, the underlying hormonal dysfunction continues to fuel increased hair growth, limiting the long-term impact.
Consulting an endocrinologist to address the root hormonal imbalance is advised in these cases for best results.
To get the most out of each laser hair removal session, Dr. Soni stresses proper preparation of the treatment area. However, many patients fail to adequately prepare, limiting the effectiveness of the laser treatment.
Here are the key pre-treatment steps that must be followed religiously:
Insufficient patient compliance with these guidelines between sessions is a common reason for suboptimal laser hair removal results.
Another mistake Dr. Soni points out that is using the wrong treatment parameters and settings based on the area being targeted.
Different body parts have varying hair thickness, density and growth cycles. The practitioners must tailor the laser device settings, including wavelength, beam size, and cooling based on which body part is being treated:
Using a one-size-fits-all laser setup leads to poor long-term hair reduction on thinner facial and underarm hair, and risks burning and scarring delicate bikini skin. Customizing the parameters based on the body part characteristics is key for safety and optimal results.
The laser hair removal provider’s skill and experience play a huge role in determining the efficacy and safety of the treatment. However, many providers lack the rigorous training needed to properly operate these devices.
This highlights the importance of getting your laser hair treatment done by highly experienced experts like Dr. Soni.
Here are the red flags indicating a poorly trained laser hair removal technician:
Opting for an experienced provider who has extensive supervised training under a dermatologist and knows how to tailor the treatments can make a big difference in your results and safety. Don’t take shortcuts with your skin.
Certain medications can stimulate increased hair growth that may overcome the beneficial effects of laser hair removal treatments.
Some common drugs that are implicated in extra hair growth include:
Checking with your prescribing physician to see if alternative medications are available is recommended. This allows the laser hair removal to work unimpeded to deliver the desired results.
Laser hair removal technology has evolved considerably over the past decade, with newer devices capable of treating a wider range of hair and skin types.
Some signs that a clinic is using obsolete laser technology include:

Laser hair removal can provide permanent hair reduction when performed properly over a series of treatments. Most patients see a 10-25% drop in hair growth after each session. While not 100% hair-free, most achieve 60-90% long-term hair reduction after an average of 6-8 sessions.
Laser hair removal works best for those with light skin and dark coarse hair. However, newer long-pulse Nd:YAG lasers containing integrated skin sensors and cooling can now also safely treat those with medium to dark skin tones. Patients with very fair hair still remain challenging.
Most patients describe the laser pulses as rubber band snaps on the skin. Lasers equipped with advanced integrated cooling systems significantly reduce discomfort during treatment. Topical anesthetics can also be applied beforehand for high pain areas like the bikini line.
If hair regrows after initial success with laser removal, causes can include hormonal conditions stimulating growth, natural hair cycling, inadequate device settings, or poor practitioner technique. Consulting a dermatologist experienced in hair removal can help determine the cause.
Laser hair removal is minimally effective for white, gray or blonde hair since the weaker melanin pigment does not absorb enough laser energy to damage the follicle. Patients with dark coarse hair respond best. Electrolysis may be an alternative for lighter hair colors.
Most patients require 6-8 laser hair removal sessions spaced 4-6 weeks apart to successfully damage the majority of hair follicles and prevent regrowth. Periodic maintenance may be needed in hormonally sensitive areas. Only 80-90% permanent reduction is typically achievable, not 100% removal.
Since hairs naturally grow in different cycles, not all follicles will be active and able to be targeted during any single treatment session. Multiple treatments are needed to disable hairs in all growth stages for long-term reduction.
The average cost for full body laser hair removal is 00 to 00 depending on the number of sessions needed. Larger treatment areas like the legs and back will have higher costs than smaller delicate areas like the face and bikini region.
The Tria 4X and the newer Tria Smooth devices are FDA-cleared for at-home use. However, they may not disable coarse hair as effectively as the more powerful in-office lasers containing integrated cooling systems. At-home lasers work best for thinner lighter hair.
Tanning should be avoided at least 4 weeks before and after each laser session. Exposure darkens the skin, decreasing the contrast between the pigment in the hair follicles and the surrounding skin. This can impact laser precision and increase adverse effects.
Laser hair removal used to be challenging for those with darker skin. However, new long-pulse Nd:YAG lasers containing specialized cooling systems allow safer, effective treatment of dark skin. An experienced technician also helps reduce side effects.
Since not all hair follicles are actively growing at once, multiple treatments are needed to target the follicles in different stages of the growth cycle. On average 6-8 visits spaced 4-6 weeks apart catches the majority of hair follicles successfully.
Exposure to UV rays can potentially trigger adverse effects on lasered skin. It’s best to avoid any tanning including self-tanners for 4-6 weeks after each laser session. The treatment area skin needs time to fully heal between appointments.
Laser hair removal is effective for removing facial hair, but requires careful precision and lower settings. The thinner vellus hairs and delicate facial skin need an experienced practitioner. For women with hormonal hair growth, combination treatment is recommended.
For large areas, laser hair removal usually works better than electrolysis since multiple hairs can be treated simultaneously. Electrolysis targets one hair at a time, requiring numerous repetitive sessions. So laser hair removal provides faster results.
