Laser Hair Removal Myths Debunked by a Top NYC Dermatologist: What You Really Need to Know

If you’re exploring laser hair removal in NYC, chances are you’ve encountered a host of myths and misconceptions that make you hesitate. From fears of intense pain, to doubts about skin tone compatibility, or unrealistic expectations about instant results, these misunderstandings often prevent people from experiencing one of the most effective solutions for long-term hair reduction.

To help clear the confusion, we spoke with Dr. Debra Jaliman, a board-certified New York City dermatologist, to separate fact from fiction. Whether you're new to the treatment or still deciding if it's right for you, this blog will give you the truth about laser hair removal—so you can make an informed choice and feel confident on your journey to smoother skin.

Top Laser Hair Removal Myths—Debunked

Myth #1: Laser Hair Removal Is Extremely Painful

Many people worry that laser hair removal is painful, but that’s a major misconception. In reality, most patients describe the sensation as similar to a rubber band snap—brief and manageable. According to the American Society for Dermatologic Surgery, over 75% of patients found the pain much less than expected.

Myth #2: Laser Hair Removal Only Works on Light Skin

This outdated myth stems from early technologies that struggled with darker skin tones. Today, advanced lasers like the Nd:YAG are specifically designed for safe and effective treatment on all skin types, including deeply pigmented skin.

Myth #3: One Session Is Enough for Permanent Results

Contrary to popular belief, laser hair removal is not a one-and-done treatment. Hair grows in different cycles, and multiple sessions are needed to target follicles during their active growth phase. Most dermatologists recommend 6 to 8 sessions, spaced about 4–6 weeks apart, for optimal long-term results.

How Laser Hair Removal Works

Laser hair removal targets the pigment (melanin) in hair follicles using concentrated light energy. This light converts to heat, which damages the follicle, slowing or halting future hair growth.

Step 1: Targeting the Hair Follicle

The laser’s light is absorbed by the melanin in the hair, precisely heating the follicle without harming the surrounding skin.

Step 2: Disabling Hair Growth

The heat damages the follicle, inhibiting its ability to regrow hair. Because not all follicles are active at once, repeated sessions are essential.

Types of Laser Technology: What’s Right for You?

Choosing the right laser system is critical. Here’s a breakdown of common types used in professional dermatology clinics:

Alexandrite Laser

• Best for: Light to olive skin
• Known for: Fast treatment sessions on larger areas (legs, back)

Diode Laser

• Best for: A variety of skin tones
• Known for: Effectiveness on coarse hair, especially bikini line and underarms

Nd:YAG Laser

• Best for: Dark skin tones
• Known for: Safety and precision, thanks to deep penetration and minimal skin damage

Ruby Laser

• Best for: Fine, light hair
• Less commonly used due to newer, more versatile technologies

Does Laser Hair Removal Hurt? What to Expect

Worried about pain during laser hair removal? Most modern lasers feature cooling mechanisms to soothe skin in real-time. Plus, topical numbing creams are available for sensitive areas. According to Dr. Jaliman, discomfort is minimal and well-tolerated by most patients.

Treatment time is typically 20–30 minutes per area, with no downtime—making it easy to fit into a busy schedule.

Laser Hair Removal for All Skin Types: Personalized for You

Not all skin responds the same way to lasers. That's why dermatologists use the Fitzpatrick Skin Type Scale to determine which laser system is best for you:

Your skin tone and hair color both play crucial roles in determining treatment success. Lasers work best when there’s contrast between the hair and skin—dark hair on light skin is ideal, but modern lasers make safe, effective treatment possible for nearly everyone.

How Long Do Results Last?

Laser hair removal provides long-term results. Here’s what most patients experience:

Hormonal changes (like PCOS or pregnancy) can affect results, so personalized care is essential.

Expert Tips from NYC Dermatologist Dr. Debra Jaliman

"Laser hair removal should never be one-size-fits-all,” says Dr. Jaliman.

She recommends:

• Consulting a board-certified dermatologist
• Choosing a clinic experienced in treating all skin tones
• Being honest about your hair color, skin type, and medical history

A tailored plan ensures maximum safety and superior results.

Quick FAQ: What You Need to Know

How many sessions are needed for permanent results?

Most people need 6 to 8 sessions for lasting hair reduction.

Are there any risks? Temporary redness or swelling is common. Rare side effects include hyperpigmentation or burns, especially on darker skin—which is why expert care matters.

Does it work on all hair types?

Works best on dark hair. Blonde, red, or gray hair may respond poorly due to low melanin content.

Is it safe for dark skin?

Yes—with the right laser (like Nd:YAG) and a qualified provider.

Myth 4: You Can’t Get Laser Hair Removal in Summer

One of the most common laser hair removal myths is that it's unsafe or ineffective during the summer months. While it's true that laser hair removal works best on untanned skin, that doesn’t mean summer treatments are off the table.

Truth: You can undergo laser hair removal in summer—you just need to take extra precautions. Avoid direct sun exposure before and after treatments, use sunscreen, and follow your technician’s aftercare instructions. Many people actually start their sessions in the summer to be hair-free by the next season.

Myth 5: Laser Hair Removal Is Only for Women

Gone are the days when smooth skin was marketed exclusively to women. This outdated belief is one of the biggest laser hair removal myths.

Truth: Laser hair removal for men is not only common, it's growing in popularity. Men often seek treatment for areas like the back, chest, neck, and beard line. The procedure is equally effective and safe for all genders.

Myth 6: At-Home Devices Work Just as Well as Professional Treatments

There’s a growing market for at-home laser hair removal devices, and while they can be tempting, believing their as effective as professional treatments is a major laser hair removal myth.

Truth: Professional laser hair removal uses medical-grade devices that are more powerful, precise, and customizable than at-home versions. While at-home laser devices may offer some results for minor touch-ups, they can’t match the long-lasting effectiveness and safety of professional treatments performed by certified technicians.

Myth 7: Laser Hair Removal Causes Ingrown Hairs

Another widespread laser hair removal myth is that it causes ingrown hairs, especially in sensitive areas like the bikini line or underarms.

Truth: Laser hair removal helps prevent ingrown hairs, especially for those prone to irritation from shaving or waxing. By targeting the hair follicle and reducing regrowth, it actually minimizes the chances of hair becoming trapped under the skin.

Myth 8: Laser Hair Removal Is Too Expensive

Many people assume that laser hair removal is a luxury reserved only for a select few due to the cost.

Truth: While the upfront cost may seem higher than shaving or waxing, laser hair removal is a long-term investment. Over time, it can be more cost-effective, especially when you factor in the price of razors, waxing appointments, and creams. Plus, many clinics offer laser hair removal packages or financing options to make treatments more accessible.

Myth 9: “You Can’t Shave Before or After Laser Hair Removal”

Reality: Not only can you shave before a laser hair removal session—it’s actually recommended.

Why? Laser targets the pigment in the hair follicle. Shaving the treatment area 12–24 hours before your session ensures that the hair is below the skin surface, reducing the risk of burns and improving laser accuracy. After the session, shaving is the only approved method of hair removal between treatments.

Avoid: Waxing, plucking, or threading (more on that below).

Myth 10: “Laser Hair Removal Is Unsafe for Sensitive or Intimate Areas”

Reality: Laser hair removal is safe and effective for sensitive skin and intimate areas, including the bikini line, Brazilian, underarms, and even the face.

In fact, lasers are often ideal for delicate skin, reducing the long-term irritation caused by constant shaving or waxing. What matters most is that your treatment is performed by a licensed technician using technology suitable for your skin tone and hair type.

Tip: Always request a patch test first, especially if you’re prone to reactions or hyperpigmentation.

Myth 11: “It’s Fine to Wax or Pluck Between Laser Sessions”

Reality: Big no-no. Waxing or plucking between sessions removes the hair follicle, which the laser needs in place to work effectively.

Only shaving is allowed between appointments. Interrupting the hair growth cycle by waxing or plucking will reduce the effectiveness of your treatment and potentially prolong the number of sessions needed.

Myth 12: “You Can Never Use Deodorant or Makeup on Treated Areas Again”

Reality: You can use deodorant and makeup—just not immediately after your session.

For the first 24–48 hours, avoid anything that might irritate the skin (e.g., fragranced deodorants, foundation, or creams). After that, you can safely return to your usual beauty routine—just make sure you’re using gentle, non-comedogenic products and avoiding anything that causes friction or clogged pores.

Myth 13: “Laser Hair Removal Makes Hair Grow Back Thicker If It Doesn’t Work”

Reality: If anything, laser hair removal leads to thinner, finer regrowth—not thicker hair.

Some patients may notice "patchy" regrowth or a return of some hairs during their treatment cycle, especially early on. This isn’t the hair growing back stronger—it's a normal part of the shedding and regrowth cycle as lasers target follicles at different stages.

If your treatment didn’t work, it could be due to:

• Hormonal imbalances (especially in PCOS or thyroid issues)
• Incorrect laser settings
• Inconsistent session timing

Laser hair removal is one of the most advanced, safe, and effective ways to get smooth skin—especially when performed correctly. Don’t let common myths stop you from experiencing the benefits.
