How Permanent Is Laser Hair Removal? - Ingrid E .Trenkle, MD (2024)

Most of us have been shaving since our tweens, but consider this: do you actually like shaving one to three times a week? Or, if you switched to waxing somewhere down the line, do you enjoy the wait-time between appointments where you have to let your hair grow out? If the answer to these questions is a resounding no, then you may want to consider a different cosmetic solution. Ingrid E. Trenkle, MD in Redlands, CA knows that laser hair removal is one of the best and most beneficial hair removal treatments available to patients.

How Permanent Is Laser Hair Removal?

The results of laser hair removalare designed to produce long-lasting results that can last for several months, even several years if the treatment is maintained correctly. However, as an important note, even if this treatment does slow down your rate of hair growth and significantly decrease the amount of hair that grows back, there’s only so much the treatment can do. It’s simply an immutable fact of life that hair will continue to grow, even if it does grow more sparsely and less quickly after this treatment.

The Short Term Results

In the short term, your results will usually last between two to eight weeks at a time. Most people enjoy an average of four weeks wonderfully hairless, which is generally the same space of time between initial treatment appointments.

Your short-term results will typically last varying lengths of time due to your natural rate of hair growth and how well your hair follicles are responding to thermal energy exposure. Fortunately, your short-term results will continue to improve with each subsequent treatment appointment.

The Long Term Results

In the long term, after your initial round of treatments, you can expect the results of your treatment to last for several months, sometimes as long as six months.

Laser hair removal will drastically slow your rate of hair growth over time, which is the most important long-term result.

How Many Treatments Will You Need?

For your initial round of treatment, most people generally require at least six to eight treatment appointments spaced four to six weeks apart to achieve desired results. The number of initial treatments you will need will vary depending on certain factors, such as how thickly your hair grows. People who have thicker hair or hair follicles that are closer together may require additional treatments to be able to treat all follicles.

How Can You Maintain Your Results?

The best way to maintain your long-term results is to attend your regular maintenance appointments, which are usually scheduled once or twice a year. Your maintenance appointments will treat your hair follicles with laser energy again to continue stunting the function of the follicles.

Between appointments, you will be able to shave any hair that continues to grow. It’s important that you do not wax or tweeze any treated areas between appointments, particularly on areas of the body that have sensitive skin. We can advise you of other ways to maintain your results during your treatment appointments.

Is There a Best Time for This Treatment?

Yes. Although you can have this treatment at any age and during any time of the year, the fact of the matter is that it’s generally best to schedule laser treatments during times of the year when you are less likely to be exposed to direct sunlight.

Many patients opt to schedule this treatment during the fall and winter months for the sake of protecting their skin. This is also true for your maintenance appointments.

Where Can You Use This Treatment?

Laser hair removal is a treatment that can be used virtually anywhere on the body where hair grows, including small and sensitive areas.

Most often, we see patients who seek to remove hair from their legs and underarms, but many patients use this treatment on the forearms, stomach, back, and bikini areas. We will build your treatment plan during your consultation appointment.

Why Is This Treatment Safe?

Many patients wonder if this treatment is safe, and the truth is that this treatment is usually a good option for most people – including those with medium to dark complexions who may not be eligible for other laser treatments. There are a few reasons for this, such as the fact that laser hair removal is a non-ablative laser treatment, which means it does not harm the skin from thermal energy and has a significantly lower risk of pigmentation.

This treatment is also considered safe because the laser technology used for laser hair removal only targets pigment that is darker than the skin tone. In other words, the laser energy is only active when the treatment system detects a hair follicle, which means that the surrounding skin is safe from thermal exposure.

How Should You Prepare for This Treatment?

There are some things you will need to do to prepare for laser treatments for hair removal. For example, some of your preparation will include instructions to avoid direct unprotected sun exposure, including tanning beds, for at least two weeks before your appointment. You will also need to avoid waxing or tweezing at least two weeks before your treatment.

You will be instructed to shave the intended treatment areas at least one to three days before your appointment, as this will make the treatment easier to complete. Please do not wear lotions, body oils, or perfume to your appointment. You may want to dress in loose, comfortable clothing, as well.

What Are the Benefits of Laser Hair Removal?

In addition to being a safe treatment that is an ideal choice for virtually all patients, there are other benefits to this laser treatment that you may want to consider. Some of these benefits include:

Simpler Routine

The biggest benefit of this laser treatment is the fact that it will simplify your beauty routine, both in terms of time and money. You will not need to shave as frequently, which means you will save money on razors and other shaving products, and even other hair removal treatments like waxing. You will be able to go weeks before having to think about your unwanted body hair again, which will make your daily hygiene routine that much quicker.

More Freedom

Along with a simpler routine, you will also benefit from more freedom. When you are enjoying the results of this treatment, you won’t have to think twice about the hair under your arms or around your bikini line, which will give you more freedom in choosing clothing to wear. And because you won’t be dealing with stubble anymore, wearing certain clothes may even be more comfortable.

Avoid Ingrown Hairs

Ingrown hairs are caused by hair follicles that grow crookedly from the skin. One of the most undersold benefits of this laser treatment is the fact that successful treatments will help you avoid ingrown hairs in the future.

This is because the thermal energy used for this treatment gently corrects the alignment of the hair follicle and teaches the hair follicle how to grow hair straight. If you suffer from frequent ingrown hairs, then this may be one of the key reasons to consider this treatment.

Not Painful

This treatment is also not painful. Many patients assume that laser treatment will be painful, but the truth is that this treatment is often less uncomfortable than waxing. Some people compare the sensation of this treatment to snapping rubber bands or steady heat not unlike a tanning bed.

Depending on your level of pain tolerance, you may want to ask for certain measures to be taken for your comfort, such as applying a topical numbing cream. But on the whole, most patients don’t find this treatment particularly uncomfortable.

Improve Skin Appearance

Another lesser-known benefit of this laser treatment is the fact that it can help improve the appearance of the skin. Although the laser will only be active when it detects darker pigments, the exposure of your skin to the thermal energy of this treatment helps restore the tone, texture, and tightness of your skin. Many patients experience minor to moderate improvements to the appearance of their skin after this treatment.

Who Are Good Candidates?

Adults who are interested in simplifying their body hair maintenance routine are generally good candidates for this treatment, including patients with medium and dark complexions. However, candidates who are currently pregnant may not be eligible.

Revel in Your Smooth Skin With Laser Hair Removal

If you aren’t a fan of shaving, tweezing, or waxing, but you still want to enjoy silky-smooth and hairless skin, then you may want to consider laser hair removal. This treatment is an ideal option for virtually everyone who wants to benefit from a simpler routine. If you think laser hair removal is a good treatment option for you, please contact Ingrid E. Trenkle, MD in Redlands, CA to schedule your first appointment today.

FAQs

How many years is laser hair removal good for? ›

You can expect a 10% to 25% reduction in hair after the first treatment. To remove the hair, most patients need 2 to 6 laser treatments. After finishing the treatments, most patients do not see any hair on the treated skin for several months or even years. When the hair regrows, there tends to be less of it.

Does laser hair removal go forever? ›

Most people experience hair removal that lasts several months, and it might last for years. But laser hair removal doesn't guarantee permanent hair removal. When hair regrows, it's usually finer and lighter in color. You might need maintenance laser treatments for long-term hair reduction.

What happens if I stop laser hair removal after 4 sessions? ›

If treatment is stopped before all of the hair follicles have been destroyed, some may continue to grow. It is important to complete the recommended treatment plan to achieve the best results. Sometimes, the patient sees hairs are thicker and darker after the treatment when they have original light and fair hair.

Does at home laser hair removal work permanently? ›

Laser hair removal devices work by killing the hair follicle. But hair grows in cycles, and the lasers only damage follicles during an active cycle of hair growth. So it takes multiple treatments, about a month apart, to completely stop hair from regrowing. For some people, laser hair removal is not entirely permanent.

At what age is laser hair removal most effective? ›

One great thing about this treatment is that it's effective at any age. Whether you are 19 or 89, this treatment is the best way to permanently reduce your hair. The best time for you to seek treatment is whenever you realize that you have unwanted hair that you would be happier without.

Does laser hair removal come back after years? ›

How long does laser hair removal last? While most patients enjoy the benefits of laser treatments for many years, this procedure is technically semi-permanent. This is because some hair follicles can remain unaffected by the laser. That said, patients generally find that most hair follicles no longer grow back.

Does laser remove 100% hair? ›

In short, no. Laser hair removal works by heating the hair follicles to stop new hairs from growing. This puts the hair follicles in a state of dormancy for a long period of time — much longer than with shaving and waxing. When the hairs do grow back, they'll be lighter, finer, and fewer in number.

Why do I still have hair after laser? ›

But did you know that some hair regrowth is completely normal following hair removal appointments? If you're wondering why the hair won't disappear entirely, don't sweat it. It's all to do with the body's basic hair growth patterns.

Is laser hair removal 100% effective? ›

Laser hair removal is a safe, effective way to remove unwanted body hair. Heat from a laser removes hair and destroys hair follicles. It's not permanent, but the results last longer than plucking, tweezing or waxing. Most people need multiple treatments.

What happens if you don't keep up with laser hair removal? ›

If you miss a laser hair removal session, it's important to get back on schedule right away. The reason for this is because the hair that hasn't been treated during its growth cycle will return when it is in its growth phase.

How many laser sessions does it take to permanently remove hair? ›

Generally, clients need about two to six laser treatments in order to completely get rid of hair. You can expect to see about a 10% to 25% reduction in hair after your first treatment. As you continue your treatments, more and more hair will fall out, and you'll notice that it continues to grow back more slowly.

Is electrolysis or laser better? ›

Electrolysis is considered a more permanent solution than laser hair removal (it stops hair growth completely while laser hair removal slows and reduces hair growth), but it requires more individual sessions (closer to 14), and the sessions can take longer. You might not see full results for nearly 18 months.

Do handheld laser hair removers work? ›

At-home laser hair removal does work...

...but that doesn't mean it's always permanent. You'll likely need touch-ups every so often after you've reached your desired results — and you may end up getting an in-office treatment anyway. "Remember, IPL is not true laser technology," says Dr.

Is it worth buying at home laser hair removal? ›

If an at-home laser works for you, it may be worth the investment, as it would be significantly cheaper to use at home than to continuously get treatments at the doctor's office. However, for best results, you would have to use the device fairly often, which may make it not all that different from shaving.

How can I make laser hair removal last longer? ›

You should also avoid applying lotion, deodorant, and other cosmetic products on the skin when you show up for your appointment. Sun exposure can have an impact, as well. Because the laser targets pigment, your lovely tan could interfere with the efficacy of the treatment.

How long does laser hair removal last in Brazilian? ›

For a Brazilian you will need to be treated every 6-8 weeks. Laser hair removal work does require maintenance treatments for permanent results. About 80% of women will need at least 6 treatments, and about 20% may need up to 10 before significant results are seen. Do you shave before Brazilian laser hair removal?

How often should you have laser hair removal? ›

You'll need regular sessions to keep hair from regrowing. How often sessions are needed varies for each person. For example, you may need a session to remove facial hair every 4 weeks, and for body hair every 6 to 8 weeks. There's no guarantee laser hair removal will get rid of all the hair.

What happens if I don't shave before laser? ›

Potential Risks of Skipping the Shave

Cause skin irritation: Unshaved hair can lead to post-laser redness, inflammation, and swelling. Increase burn risk: Longer hair can excessively absorb laser energy, heightening the risk of burns and blisters.

Can you wax years after laser hair removal? ›
