How to Prepare for Laser Hair Removal


Laser hair removal has become a popular and effective method for long-term hair reduction. In terms of its procedure, the light energy emitted by the laser is first absorbed by the melanin in the hair follicle. Then it converts into heat, which damages the hair follicle and inhibits future hair growth. Preparing for laser hair removal is important to ensure you get the best results and minimize the risk of side effects. In the passage, you can specifically find out how to prepare for laser hair removal.

Questions to Ask During Your Consultation

Before undergoing the procedure, it’s necessary to have a thorough laser hair removal consultation, which can help you have a safe and successful treatment. Here you can find some questions to ask before hair removal.

1. “Are you a licensed and experienced provider?” - To ensure your consultant is qualified and experienced in performing laser hair removal.

2. “Is laser hair removal suitable for my skin and hair type?” - Your skin color and hair type should be assessed to determine whether you’re suitable for the procedure.

3. “What are the potential risks and side effects?” - Understand the possible effects, such as redness, swelling, and pigment changes, and how they can be avoided.

4. “How many treatment sessions will I need?” - Get to know the estimated number of sessions that are required for your hair removal.

5. “How do I feel during the treatment session?” - Realize the sensation you’ll experience and what you can do to minimize the potential discomfort.

Weeks Before Laser Hair Removal: Preparations

As for things to do and things to avoid before laser hair removal, first you’d better consult your dermatologist to assess your suitability for the procedure and get personalized recommendations. Drink enough water to keep your skin hydrated, so that it can recover more quickly after the treatment.

Avoid skin tanning at least six weeks before your treatment. No matter tanning beds, spray tans, or natural sun tanning, the tanned skin can absorb more laser energy, increasing the risk of side effects. Moreover, prevent from waxing, plucking, or using depilatory creams at least four to six weeks prior to the procedure.

Days Before IPL: Do’s and Don’ts

Specific preparations are required to ensure safety and effectiveness. Here are some essential do’s and don’ts before laser hair removal. For the reason that sun exposure can reduce the effectiveness of the treatment and increase the risk of complications, it’s important to protect your skin from the sun. You can use sunscreen with a high SPF, wear protective clothing, and spend less time outside to avoid sun exposure.

If you wonder whether waxing or shaving can be conducted, the fact is that you’d better shave the treatment areas one or two days before your appointment, which makes sure the procedure can not be interfered by visible hair on the skin’s surface. However, waxing should be avoided because it removes the hair from the follicle, which is the target for the laser during the procedure.

Remember to use gentle skincare products and avoid any products that contain alcohol or other irritants 24 hours before hair removal, as these ingredients can increase skin sensitivity. In addition, avoid excessive exfoliation of the skin in the days leading up to the treatment. And do not bleach the hair in treated areas, because the laser works best on darker and pigmented hair.

The Day of Your IPL Treatment

To ensure a successful IPL treatment and minimize the risk of complications, preparing for laser hair removal is essential. On the laser hair removal treatment day, your skin should be clean and free from lotions, creams, and even makeup. Speaking of clothes to wear for hair removal on the day of your appointment, wear loose-fitting and comfortable clothing to avoid unnecessary friction and irritation.

Besides tips for laser hair removal preparation, you should also know what to expect on that day. After check-in, a brief consultation may be conducted to ensure that your skin and hair condition has not changed. After completing consent forms, you will be taken to the treatment room where you may need to change into a gown or remove clothing to expose the area being treated.

During the Session: What to Expect

When you get ready for laser hair removal, the procedure can be started. The practitioner will first apply a gel to your skin, and then use a handle to deliver short bursts of intense light to the hair follicles. You may feel a mild stinging or snapping sensation during the procedure, which is usually well-tolerated.

In terms of the duration of the treatment, it varies depending on the size of the area being treated. It only takes a few minutes to remove facial hair or armpit hair, while larger areas may take longer, such as leg hair, chest hair or back hair.

After the Session: Immediate Care

Slight redness and swelling may appear on treated areas after hair removal session. And you may feel sensitive, similar to a mild sunburn. Although these effects normally subside within a day or two, you can apply a cool compress or aloe vera gel on the skin’ surface to soothe the discomfort.

One or two weeks after the procedure, the treated hair may appear to darken and then fall out, which proves that the laser has successfully targeted the root of the hair. During this period, you’d better avoid hot showers, saunas, or other sources of heat. Moreover, scrubs, loofahs, or any harsh exfoliating products should also be put aside.

But you need to clearly recognize that your unwanted hair can not be removed completely after the first-time laser hair removal. Multiple sessions are typically required in different stages of hair growth, and the recommended interval between sessions is normally 4~6 weeks.


The passage has specifically told about the laser hair removal preparation weeks and days before the treatment, as well as how to do the post-care. It should be admitted that well preparing for laser hair removal can not only enhance the effectiveness to get optimal results, but also ensure your safety and minimize discomfort.


1. Do you need to shave before hair removal?

Shaving is often recommended before laser hair removal. When the hair is trimmed closer to the skin’s surface, the laser can target the hair follicles more effectively because it won’t waste energy on the long hair above the skin. But you’d better shave the area where hair is to be removed one or two days before the treatment.

2. What is the best age for hair removal?

Actually there isn’t the so-called “best age” for laser hair removal, because whether it’s suitable to be conducted depends on factors like hair color, skin type rather than age. However, it should be admitted that hormonal changes can affect hair growth. For long-lasting results, it’s advised to wait until hormonal fluctuations have been stable before making a laser hair removal appointment.

3. What should I wear for hair removal?

You’re recommended to wear loose-fitting and comfortable clothes when you prepare for IPL, which ensures both your comfort and effectiveness of the treatment. And you can selectively expose the body parts according to your treatment areas. For example, if you aim to remove your leg hair, you’d better wear shorts or a skirt so that it’s more convenient to access the area.

4. What is A Laser Hair Removal Patch Test?

It’s a procedure that is often conducted before undergoing a complete laser hair removal treatment. First, a small and inconspicuous area will be selected. After cleansing the area, the cooling gel is going to be applied. When laser hair removal works, the treated area can be observed for any immediate reactions. The results of the patch test plays a key role in determining whether you’re suitable for the treatment and any adjustments can be made.

5. What results to expect from the first hair removal session?

After the first session, a reduction in hair density can be noticed. The hair growth may be slower than before. And the treated hair may be finer in texture. But the results after the first session typically can not come to your expectations. Hair grows in different cycles, and the first session usually targets hair in the active growth phase. So you need to take multiple sessions for significant and long-lasting hair reduction.

6. Why is numbing cream required for laser hair removal?

As the intense pulse of the laser targets hair follicles, discomfort or even pain can be caused. Numbing cream helps to reduce or minimize the sensation, making the procedure more tolerable. This can be beneficial for individuals with skin more sensitive or a low pain threshold. Moreover, the anxiety caused can be alleviated when numbing cream is incorporated.

7. Is it OK to not shave before laser hair removal?

Generally, it’s recommended to shave before undergoing laser hair removal, because shaving can ensure that the laser can effectively target the pigment within the hair follicle, without interference from the visible hair on the skin’s surface. And if the hair is too long, it can absorb excess laser energy, potentially causing discomfort or skin damage. Therefore, shaving can also help reduce the potential risk of surface
