Laser Hair Removal: Procedure, Preparation, and Recovery

Posted on: June 1, 2024

Understanding Laser Removal

Science Behind

Laser hair removal uses laser energy and selective photothermolysis to target melanin in hair follicles. The laser emits light that is absorbed by the melanin pigment in the hair follicle through selective photothermolysis. This absorption heats and damages the follicle. As a result, it inhibits future hair growth.

Different types of lasers are used for different skin tones and hair colors, utilizing selective photothermolysis and light energy to target melanin as determined by a dermatologist. For example, Alexandrite lasers work well on light skin. Nd:YAG lasers are better for darker skin tones.

Effectiveness Comparison

Traditional methods like shaving and waxing provide temporary results. Shaving cuts the hair at the surface level. Waxing pulls out hair from the follicle root but does not prevent regrowth.

Laser hair removal treatments offer more permanent solutions. After several sessions with a dermatologist, many people with sensitive skin experience significant reduction in hair growth due to selective photothermolysis without adverse effects. The procedure is faster and less painful for unwanted hair compared to waxing.

Misconceptions Addressed

We believe laser treatments only work on light-skinned individuals with dark hair and specific types of melanin, as advised by a technician or doctor. Modern technology has improved to accommodate various types of skin tones and hair colors, considering melanin.

Others think laser removal is unsafe or painful. Most people find it tolerable, describing it as a snapping rubber band sensation on various skin types during unwanted hair reduction.

Key Benefits

Precision Targeting

Laser hair removal precisely targets dark, coarse hairs. The laser’s light energy focuses on the pigment in the hair follicles for various skin types. This leaves the surrounding skin undamaged. This precision reduces the risk of skin damage, makes it suitable for sensitive areas like the face and bikini line, and is effective for unwanted hair reduction targeting the hair matrix.

Speed of Procedure

The procedure is fast. Each laser pulse treats multiple hairs in a fraction of a second. Small areas like the upper lip can be treated for hair reduction in less than a minute. Larger areas, such as the back or legs, take about an hour for hair reduction.

Predictable Results

Patients often experience predictable results. Most achieve permanent hair loss after three to seven sessions. This consistency makes it a reliable option for long-term hair removal.

Suitable for Large Areas

Laser hair removal can treat large areas effectively. This makes it ideal for hair reduction in regions like the back, chest, and legs. The ability to cover substantial areas quickly sets it apart from other methods like waxing or electrolysis.

Minimal Side Effects

Common side effects are minimal and temporary. These may include redness or swelling, which usually subside within a few hours. Proper eye protection during treatment ensures safety.

Long-Term Savings

While initial costs are higher, long-term savings are significant. Fewer sessions mean fewer expenses over time compared to regular waxing or shaving products.

Preparing for Treatment

Avoid Sun Exposure

Patients must avoid sun exposure before laser hair removal. Sunburned or tanned skin increases the risk of complications. It can lead to burns and pigmentation changes. Use sunscreen with a high SPF if going outdoors.

Skip Waxing and Plucking

Do not wax, pluck, or use electrolysis six weeks before treatment. These methods remove hair follicles. Laser hair removal targets these follicles. Keeping them intact ensures effective treatment.

Shave the Day Before

Shaving the treatment area the day before is crucial. It reduces the risk of surface skin burns during the procedure. Shaving leaves the hair shaft visible but removes above-the-skin hair that can cause burns.

Consult a Doctor

Consult a medical doctor or dermatologist before starting treatments. They assess your skin type and hair color. This helps in creating a personalized treatment plan. Discuss any medical conditions you have.

Understand Multiple Treatments

Laser hair removal requires multiple treatments for optimal results. Hair grows in cycles, and lasers target active growth phases. Most patients need 6-8 sessions spaced several weeks apart.

Prepare for Discomfort

e discomfort is common during laser treatments. Patients might feel a snapping sensation on their skin. Technicians often use cooling devices to minimize this feeling.

Post-Treatment Care

After each session, follow post-treatment care instructions carefully:

  • Apply ice packs to reduce swelling.

  • Use soothing lotions if needed.

  • Avoid hot showers and strenuous activities for 24 hours.

Procedure Expectations

Initial Preparation

Patients will receive cooling devices or numbing cream before the procedure. This helps minimize discomfort. Cooling devices may be applied directly to the skin.

Sensation During Treatment

During laser hair removal, patients often feel a snapping sensation. It is similar to a rubber band being snapped against the skin. Some areas might be more sensitive than others.

Session Duration

The duration of each session varies. For small areas like the upper lip, it may take just a few minutes. Larger areas, such as the back or legs, can take up to an hour.

Pulse Duration and Size

Laser machines operate with specific pulse durations and sizes. Pulse duration refers to how long the laser stays on the skin. Short pulses are used for fine hair, while longer pulses target thicker hair. The size of the laser beam also matters. Larger beams cover more area quickly but may cause more discomfort.

Post-Procedure Care

After treatment, patients should expect some redness and swelling. These symptoms usually subside within a few hours. Applying ice packs can help reduce swelling.

At-Home Solutions


At-home laser hair removal devices have become popular. These devices are designed for personal use. They target body hair just like professional treatments. Some well-known brands include Tria and Philips Lumea. Users must follow the instructions carefully to avoid skin damage.

Exfoliating Scrubs

Exfoliating scrubs can help before and after laser treatments. They remove dead skin cells and prevent ingrown hairs. Use a gentle scrub two to three times a week. Avoid harsh scrubs that can irritate the skin.

Perfumed Lotions

Avoid perfumed lotions after laser hair removal. They can cause irritation and redness. Instead, use fragrance-free moisturizers. Aloe vera gel is also soothing for treated areas.

Gentle Shaving

Shaving between treatments helps maintain smooth skin. It removes visible hair without affecting the laser process. Always use a clean, sharp razor to prevent nicks and cuts.


Keeping your skin hydrated is essential. Use a good moisturizer daily to keep your skin soft and supple. Look for products with natural ingredients like shea butter or coconut oil.

Recovery and Risks

Common Side Effects

After laser hair removal, some common side effects can occur. Temporary redness is normal and usually subsides within a few hours. Swelling may also appear but typically decreases by the end of the day. Discomfort is another frequent occurrence; it feels like a mild sunburn.

To alleviate these symptoms, use ice packs on the treated area. Over-the-counter pain relievers can help with discomfort. Avoid hot showers and tight clothing to reduce irritation.

Rare Risks

Though rare, there are potential risks associated with laser hair removal. Scarring can occur if the laser penetrates too deeply or if improper techniques are used. Changes in skin color, such as hyperpigmentation or hypopigmentation, might happen.

Choosing an experienced practitioner minimizes these risks. They understand how to adjust the laser settings based on your skin type and hair color. Always verify their credentials before undergoing treatment.

Aftercare Tips

Proper aftercare ensures a smooth recovery process. Avoid direct sunlight for at least 48 hours post-treatment. Sun exposure can worsen irritation and lead to complications like burns or discoloration.

Use gentle skincare products to clean the treated area. Moisturizers help keep the skin hydrated but avoid those with fragrances or alcohols that could cause further irritation.

Understanding Costs

Factors Influencing Cost

The cost of laser hair removal depends on several factors. One major factor is the size of the treated area. Larger areas like legs or back will cost more than smaller areas like the upper lip or underarms.

Another factor is the number of sessions required. Most people need multiple sessions to achieve desired results. This can range from 4 to 8 sessions, depending on hair type and growth rate.

Size of Treated Area

Larger areas take more time and resources. For example, treating legs may take over an hour per session. Smaller areas like the upper lip may only take a few minutes.

Clinics often charge per session based on these sizes:

  • Small areas: $50-$150

  • Medium areas: $200-$400

  • Large areas: $600-$900

Number of Sessions Required

Hair removal requires multiple treatments for effectiveness. Hair grows in cycles, so not all hairs are targeted in one session. Most clinics recommend 4 to 8 sessions spaced weeks apart.

Each additional session adds to the total cost. Some clinics offer package deals that include multiple sessions at a discounted rate.

Long-Term Cost-Effectiveness

Laser hair removal can be more cost-effective long-term compared to traditional methods like waxing or shaving. Traditional methods require regular purchases of razors, creams, or salon visits.

Over a lifetime, these costs add up significantly:

  • Razors and creams: $10-$20 per month

  • Waxing: $30-$60 per session every few weeks

Laser hair removal has a higher upfront cost but reduces ongoing expenses. After completing the necessary sessions, maintenance treatments are minimal and less frequent.

Consulting Multiple Clinics

Consulting with multiple clinics helps you understand market rates and available packages. Different clinics offer various pricing structures and promotions.

Ask about:

  • Session costs

  • Package deals

  • Discounts for multiple areas treated together

  • Financing options if available

Anticipating Results

Number of Sessions

Laser hair removal requires multiple sessions for optimal results. The number of sessions needed can vary based on several factors. Hair color, type, and treatment area play key roles. Darker hair absorbs more laser energy, making it easier to treat. Lighter hair may need more sessions.

For most people, 6-8 sessions are common. These sessions are usually spaced 4-6 weeks apart. This spacing allows the hair growth cycle to align with the treatment schedule.

Hair Regrowth

Hair regrowth is possible after laser hair removal. Different factors influence this regrowth. Hormonal changes can cause new hair growth. Pregnancy or menopause might trigger these changes.

e areas of the body are more prone to regrowth than others. For example, facial hair might return faster due to hormonal influences. Regular maintenance sessions can help manage this regrowth effectively.

Patience and Consistency

Patience is crucial in achieving the best outcomes with laser hair removal. Results do not appear overnight. Consistency in following through with the recommended treatment plan is essential.

Skipping sessions can delay progress and reduce effectiveness. Adhering to the schedule ensures that each session targets hairs at the right growth stage.


Pain Level

Many people ask if laser hair removal is painful. The pain level varies from person to person. Some describe it as a mild discomfort, like a rubber band snap. Others feel more intense sensations.

Treatment Frequency

How often do you need treatments? Typically, multiple sessions are required. Most people need 6-8 sessions for optimal results. Sessions are usually spaced 4-6 weeks apart.

Safety Concerns

Is laser hair removal safe? Yes, it is generally safe when performed by trained professionals. The FDA has approved several laser devices for hair removal.

Permanent Reduction vs Removal

There is confusion between permanent hair reduction and permanent hair removal. Permanent hair reduction means fewer hairs will grow back over time. Permanent hair removal implies no regrowth ever, which is rare.

Choosing a Clinic

How to choose a reputable clinic? Look for clinics with certified practitioners. Check reviews and ask for before-and-after photos of previous clients. Ensure the clinic uses FDA-approved lasers.

Suitable Areas

Which areas can be treated? Common areas include the upper lip, back, legs, and underarms. Laser treatment can target almost any part of the body except around the eyes.

Skin Types and Hair Colors

Does skin type or hair color matter? Yes, they do. Laser works best on light skin with dark hair due to the contrast. Newer lasers like Nd:YAG can treat darker skin tones too.

Side Effects

What are the common side effects? Temporary redness and swelling are common after treatment. Rarely, blistering or changes in skin color may occur.

Preparation Before Treatment

What should you do before your appointment? Avoid sun exposure and tanning creams for at least two weeks before treatment. Shave the area to be treated but avoid waxing or plucking.

Post-Treatment Care

How should you care for your skin after treatment? Apply soothing creams like aloe vera gel to reduce irritation. Avoid sun exposure and wear sunscreen on treated areas.


Laser hair removal offers a convenient and effective solution for managing unwanted hair. By understanding the procedure, benefits, and costs, you can make an informed decision that suits your lifestyle and needs.
