Can I Put Deodorant On Before Laser Hair Removal

The question, “Can I put deodorant on before laser hair removal?” has been posed often.

Yes, to answer briefly. In fact, many dermatologists advise doing just that! Deodorant helps keep the hair from getting brittle and making it easier for the laser to remove, therefore your dermatologist will advise you to use it before your visit.

This could seem unusual if you’ve never undergone laser hair removal before. Yet if you give it any thought, it makes sense. Chemicals in deodorant aid in preventing sweat from reaching your skin, which keeps bacteria out as well. When exposed to a strong laser, that germs can irritate the skin in addition to being disgusting! Therefore, by using deodorant beforehand, you’re actually benefiting yourself in two ways: first, by keeping bacteria out of the picture (and thereby reducing the possibility of irritation or infection), and second, by ensuring that any bacteria that does get in there is immediately killed off by the deodorant’s ingredients (like aluminum zirconium tetrachlorohydrex gly).

Why Should You Avoid Deodorant Before Laser Hair Removal?

Deodorant is a common product that many people use on a daily basis to combat body odor. However, what most people don’t realize is that deodorant contains aluminum, which can have unintended consequences when it comes to other beauty treatments, specifically laser hair removal.

When laser light is applied to the skin during a hair removal treatment, it targets the pigment in the hair follicle, ultimately destroying it and preventing future hair growth. However, the aluminum in deodorant can create a barrier on the skin that blocks the laser light from reaching the hair follicles effectively. This can result in the treatment being less effective, leading to the need for additional sessions and increased costs for the individual seeking laser hair removal.

It is important for individuals undergoing laser hair removal to be aware of this potential issue and take steps to ensure that their skin is free of any barriers that could interfere with the treatment. One way to avoid this problem is to refrain from using deodorant on the day of the laser hair removal treatment. This will allow the laser light to penetrate the skin more effectively, increasing the chances of a successful treatment outcome.

Additionally, individuals can also opt for aluminum-free deodorant options if they are concerned about the impact of aluminum on their laser hair removal treatments. There are many natural and organic deodorant products available on the market that do not contain aluminum, offering a safe alternative for those who wish to continue using deodorant while undergoing laser hair removal.

In conclusion, while deodorant is a common and essential part of many people’s daily hygiene routine, it is important to be aware of its potential impact on other beauty treatments like laser hair removal. By taking proactive steps to avoid using deodorant on the day of a laser hair removal treatment or opting for aluminum-free alternatives, individuals can ensure that they are getting the most effective and cost-efficient results from their hair removal sessions.

Additionally, deodorant can cause skin irritation when combined with the heat generated by the laser. This can lead to redness, itching, and discomfort during and after the treatment. The combination of deodorant and laser hair removal can also cause hyperpigmentation, a condition where the skin becomes darker than its surrounding areas.

Tips for Preparing for Laser Hair Removal

To ensure that your laser hair removal treatment is as effective as possible, it’s important to properly prepare beforehand. Here are some tips to help you prepare:

  • Shave the area where you will be getting laser hair removal 24 hours before your appointment. This allows the laser to better target the hair follicles.
  • Do not apply any deodorant, lotions, creams, or makeup to the area where you will be getting laser hair removal. These products can block the laser light and make the treatment less effective.
  • Wear loose, comfortable clothing to your appointment. Tight clothing can cause irritation and discomfort during the treatment.
  • If you are taking any medications, be sure to tell your laser hair removal technician. Some medications can increase sensitivity to light, making the treatment more uncomfortable.
  • Avoid sun exposure for at least two weeks before your appointment. Sunburned or tanned skin can increase the risk of complications and reduce the effectiveness of the treatment.

What to Expect During and After Laser Hair Removal

During laser hair removal, a handheld device is used to apply the laser light to the treatment area. You may feel some discomfort or a slight burning sensation during the treatment, but most people find the discomfort to be manageable. If you have sensitive skin, your technician may apply a numbing cream to the area beforehand.

After the treatment, you may experience some redness, swelling, and bruising in the treated area. This is normal and should go away within a few days. You can use a cold compress or over-the-counter pain medication to alleviate any discomfort.

It’s important to avoid sun exposure and strenuous activity for a few days after your treatment, as both can increase the risk of complications. You should also avoid using deodorant for at least 24 hours after your treatment.

In conclusion, wearing deodorant before laser hair removal is not recommended. Deodorant can block the laser light from reaching the hair follicles, making the treatment less effective and potentially causing skin irritation. By properly preparing for your appointment and following your technician’s instructions, you can ensure that your laser hair removal treatment is as effective as possible.


Here is some common mistakes make by most people during laser services. Sometimes even neglected by some untrained technician.

1. Deodorant is the number one enemy for Diode Laser with cooling gel. It will create a white substance, and it deflects laser light. Even with some residue, it will significantly reduce the effective of laser hair removal.

Most common side effects including excessive irritation, redness, and even hyper-pigmentation.

2. Makeups can cause some serious complication during laser treatment. As many makeups may change the skin tone, they will either absorb or deflect laser energy.

Serious burnt can result from makeup residuals

3. Switching between different lasers service provider. If you are getting treatments on the same area from your new service provider, you will need to make sure the laser utilizes the same or similar wavelength. In some extreme cases, hair regrowth will happen when switching between different laser equipment.

Here is some easy step to prepare yourself for laser hair removal

1. Stay away from the sun for at least 1 week (Only experienced technician, can provide services within such period, remember to notify and ask your technician if he/she is comfortable with recently tanned skin)

2. Avoid plucking, waxing and electrolysis. These hair removal methods can disturb the hair follicle and interfere with laser hair removal.

Shaving is OK, however, since it preserves the hair shaft and follicle. In fact, shaving is recommended so that the laser doesn’t target hair above the skin, potentially causing burns.

3. Avoid antibiotics, most antibiotics cause skin photosensitive reaction to laser treatments which results in adverse reactions, such as wild redness, scarring, hypo-pigmentation, hyper-pigmentation, and etc.

4. No Accutane for at least 4 months(recommended for 6 months) before your appointment.

5. For facial hair removal, you should have makeup removed before your session starts.

6. For underarms hair removal, you should remove deodorant prior to your laser sessions.

Bad Underarm Odor After Laser Hair Removal

After undergoing laser hair removal, some individuals may notice an increase in body odor. This phenomenon can be attributed to the disruption of the natural microbiome in the treated area. The human body is home to a diverse array of bacteria, both beneficial and harmful, that play a crucial role in maintaining overall health.When undergoing laser hair removal, the intense heat from the laser can disturb the balance of bacteria in the skin. This disruption can result in an overgrowth of odor-causing bacteria, leading to an increase in body odor. Additionally, the heat from the laser can cause sweating, further exacerbating the issue.The types of bacteria present in the skin can vary depending on factors such as diet, hygiene practices, and genetics. Disrupting this delicate balance can have unintended consequences, including changes in body odor. It is important to note that not everyone will experience an increase in body odor after laser hair removal, as individual responses can vary.To address this issue, individuals can take steps to restore the balance of bacteria in the skin. One option is to use probiotic skincare products, which contain beneficial bacteria that can help restore the microbiome. Additionally, maintaining good hygiene practices, such as regular showering and using antibacterial soap, can help keep odor-causing bacteria at bay.

Factors contributing to changes in body odor after laser hair removal:Disruption of the skin’s microbiomeIncreased sweating due to laser treatmentIndividual variations in bacterial composition

It is essential to consult with a dermatologist if you experience persistent changes in body odor after laser hair removal. They can provide guidance on appropriate skincare products and hygiene practices to help restore the balance of bacteria in the skin. By addressing the underlying cause of increased body odor, individuals can feel more confident and comfortable in their skin.

“This leads to the odour-producing bacteria colonising the area, and in this instance the presence or non-presence of hair is usually secondary. Hair can both help and worsen body odour, depending on the circumstances.”

Can I Shower Before Laser Hair Removal

Shower. While the treatment area itself will be cleaned before treatment begins, it is a good idea to have a bath or shower before coming in – remember no lotions, oils, or fragrances on the treatment area though!
