How Laser Hair Removal Actually Works
At its core, laser hair removal relies on a principle called selective photothermolysis. The laser emits a specific wavelength of light that gets absorbed by melanin – the pigment that gives hair its colour. This light energy converts to heat, which travels down the hair shaft and damages the follicle responsible for hair growth.
Here is the crucial detail that determines success: hair grows in cycles, and the laser is only effective during the active growth phase (anagen phase) when the hair is connected to its follicle. At any given time, only 20-30% of your hair is in this phase. This is precisely why multiple sessions are necessary – each treatment catches a different batch of hairs in their vulnerable growth stage.
The goal is not instant hair removal but progressive follicular damage. With each session, more follicles are disabled until the vast majority can no longer produce hair. Most patients achieve a 70-90% permanent reduction after completing their treatment course.
Why Laser Type Matters for Indian Skin
Not all lasers are created equal, especially when it comes to treating Indian skin. The challenge lies in melanin – Indian skin (Fitzpatrick types III-VI) contains more epidermal melanin, which means lasers designed for lighter skin can accidentally target the skin itself rather than just the hair, causing burns or pigmentation changes.
Understanding the different laser technologies helps you make an informed choice:
Diode Laser (800-810 nm)
The diode laser has become the workhorse of the hair removal industry, particularly for Indian skin. Operating at 800-810 nm wavelength, it penetrates deep enough to reach hair follicles while being relatively safe for darker skin tones. Modern diode systems with cooling technology have significantly reduced the discomfort that was once associated with these treatments.
Nd: YAG Laser (1064 nm)
The Nd: YAG laser operates at the longest wavelength used for hair removal, making it the safest option for darker skin and tanned complexions. Because this wavelength is absorbed less by epidermal melanin, there is minimal risk of skin damage. The trade-off is that it typically requires more sessions compared to shorter wavelength lasers, as its efficacy per session is somewhat lower.
Alexandrite Laser (755 nm)
Traditionally considered unsuitable for Indian skin due to its shorter wavelength and higher melanin absorption, newer Alexandrite systems with advanced cooling and pulse technology have changed this. These modern devices can now safely treat olive and medium-toned skin, though they remain unsuitable for very dark complexions.
Triple-Wavelength Systems
The latest advancement in laser hair removal technology combines all three wavelengths – Alexandrite, Diode, and Nd: YAG – in a single platform. These systems target hair at three different depths: the bulge, bulb, and papilla of the follicle. For Indian skin, this combined approach delivers better results with enhanced safety.
Laser Comparison for Indian Skin
| Laser Type | Wavelength | Indian Skin Safety | Efficacy |
| Nd: YAG | 1064 nm | Excellent | Good (more sessions) |
| Diode | 800-810 nm | Very Good | Very Good |
| Alexandrite | 755 nm | Moderate* | Excellent |
| Triple-Wave | Combined | Excellent | Excellent |
*Modern Alexandrite systems with advanced cooling can be used on medium skin tones with proper settings.

What Areas Can Be Treated?
Laser hair removal can be performed on virtually any area of the body where unwanted hair grows. Each area has its own characteristics that affect treatment:
Face
Facial hair removal requires precision and expertise due to the delicate skin and visibility of the area. Common treatment zones include the upper lip, chin, sideburns, and full face. For women dealing with hormonal hair growth, addressing the underlying cause alongside facial laser treatment yields the best long-term results.
Underarms
The underarm area responds exceptionally well to laser treatment because the hair is typically coarse and dark – ideal laser targets. Most patients see a significant reduction within 4-6 sessions. An added benefit is the improvement in skin texture and reduction in the darkening that can occur from shaving or waxing.
Bikini and Brazilian
The bikini area is one of the most requested treatment zones. Options range from basic bikini line treatment to complete Brazilian hair removal. The coarse nature of hair in this region means excellent laser response, though the sensitivity requires an experienced practitioner who can adjust settings appropriately.
Legs and Arms
Large body areas like legs and arms were once time-consuming to treat, but modern lasers with larger spot sizes and rapid firing rates have dramatically reduced session times. Full legs can now be treated in under an hour, making comprehensive hair removal practical and efficient.
Back and Chest (Men)
Laser hair removal for men has seen tremendous growth in recent years. Back and chest treatments address large areas of coarse hair that are difficult to manage with traditional methods. Men also increasingly seek treatments for neck, shoulders, and beard line shaping.

The Treatment Journey: What to Expect
Understanding the complete treatment process helps set realistic expectations and ensures you get the best possible results.
Initial Consultation
Your journey begins with a thorough assessment. Your practitioner will evaluate your skin type using the Fitzpatrick scale, examine the hair characteristics in your target areas, review your medical history for any contraindications, and discuss your goals and expectations. This is also when the appropriate laser type and settings are determined.
Preparation
In the weeks before treatment, you will need to avoid sun exposure and tanning – both real and artificial. Tanned skin increases the risk of side effects. You must also stop waxing, plucking, or threading at least four weeks before your session, as these methods remove the hair root that the laser needs to target. Shaving is actually required 24-48 hours before treatment.
During the Session
The treatment area is cleaned and marked. Depending on the system used, a cooling gel may be applied. You will be given eye protection to shield against laser light. The practitioner then passes the laser handpiece over your skin in a systematic pattern, delivering pulses of light. Modern cooling systems make this experience far more comfortable than older technologies.
Treatment times vary by area: upper lip takes 5-10 minutes, underarms 15-20 minutes, bikini line 20-30 minutes, and full legs 45-60 minutes.
After Treatment
Immediately after, you may notice redness and slight swelling around the hair follicles – this is actually a good sign indicating the hair was successfully targeted. These effects typically subside within a few hours to a day. You will need to avoid sun exposure, hot baths, and strenuous exercise for 24-48 hours.
Between Sessions
Sessions are typically spaced 4-6 weeks apart for body areas and 3-4 weeks for facial hair, following the natural hair growth cycle. During this period, you can shave if needed, but avoid waxing or plucking. You will notice that hair sheds from the treated follicles over the first two weeks.
How Many Sessions Will You Need?
This is perhaps the most common question, and the honest answer is: it depends. Several factors influence the number of sessions required:
- Hair colour and thickness: Darker, coarser hair responds better and faster than fine, light hair
- Skin tone: Deeper skin tones may require more sessions with the Nd: YAG laser for safety reasons
- Treatment area: Hormonal areas like the face and bikini may require more sessions
- Hormonal factors: Conditions like PCOS can affect hair growth patterns
- Individual response: Some people simply respond better than others
As a general guideline:
| Treatment Area | Typical Sessions Required |
| Underarms | 4-6 sessions |
| Bikini / Brazilian | 6-8 sessions |
| Legs (Full) | 6-8 sessions |
| Arms (Full) | 5-7 sessions |
| Face / Upper Lip | 6-10 sessions |
| Back / Chest (Men) | 6-8 sessions |
Most patients see a noticeable reduction after just 2-3 sessions, with results improving progressively.

Addressing Common Concerns
Is Laser Hair Removal Painful?
The experience varies from person to person and area to area, but modern laser systems have dramatically improved comfort levels. Most patients describe the sensation as similar to a rubber band snap or a warm pinch. Sensitive areas like the bikini line may be more uncomfortable, but it is generally tolerable. Advanced cooling systems – whether built into the handpiece or applied separately – significantly reduce any discomfort.
Are the Results Really Permanent?
Laser hair removal provides permanent hair reduction, not absolute permanent removal. Clinical studies show a 70-90% reduction in hair growth after completing a treatment course. The remaining hair is typically finer and lighter. Some patients may need annual maintenance sessions, particularly for hormonally influenced areas like the face.
What About Side Effects?
When performed correctly with appropriate settings for your skin type, side effects are minimal and temporary. Common effects include redness and slight swelling lasting a few hours to a day. Rare but possible complications include temporary pigmentation changes (more common in darker skin with improper settings), blistering (usually from treating tanned skin), and paradoxical hair stimulation (uncommon, but can occur with incorrect treatment of fine hair).

Can I Get Laser Hair Removal if I Have PCOS?
Yes, but expectations need to be managed. PCOS causes hormonal hair growth that may continue even after successful laser treatment. Many patients with PCOS benefit significantly from laser hair removal but may require more sessions and periodic maintenance. Combining laser treatment with hormonal management typically yields the best outcomes.
Beyond Hair Removal: Additional Skin Benefits
Many patients notice that laser hair removal improves their skin quality beyond just removing hair. The treatment can:
- Reduce ingrown hairs and the scarring they cause
- Improve the appearance of keratosis pilaris (chicken skin)
- Lighten pigmentation caused by repeated waxing or shaving
- Create smoother skin texture in treated areas
For those concerned about dark underarms or bikini areas, laser treatment combined with skin lightening treatments can address both hair and discolouration simultaneously.
Frequently Asked Questions About Laser Hair Removal in Kolkata
1. Is laser hair removal safe for dark Indian skin?
Yes, with the right laser type and settings. Nd:YAG and modern diode lasers are particularly safe for Indian skin tones (Fitzpatrick types III-VI). The key is choosing a clinic that uses appropriate technology and has experience treating diverse skin types. Avoid clinics that use only one laser type regardless of skin tone.
2. How do I prepare for my laser hair removal session?
Avoid sun exposure and tanning for 2-4 weeks before treatment. Stop waxing, plucking, and threading at least 4 weeks prior – shaving is fine and actually required 24-48 hours before your session. Come with clean skin, free of lotions, deodorant, or makeup on the treatment area.
3. Can laser hair removal treat white or grey hair?
Unfortunately, no. Laser hair removal relies on melanin to absorb the light energy. White, grey, and very light blonde hair lack sufficient melanin and will not respond to laser treatment. Electrolysis remains the only permanent solution for these hair colours.
4. What is the difference between IPL and laser hair removal?
IPL (Intense Pulsed Light) uses broad-spectrum light rather than a single wavelength laser. While effective for some hair removal, true lasers are generally more precise and efficient, requiring fewer sessions. For darker Indian skin, laser systems are typically preferred due to their greater safety margin.
5. Can men get laser hair removal?
Absolutely. Laser hair removal for men has grown significantly in popularity. Common treatment areas include the back, chest, shoulders, neck, and beard line shaping. Men can also treat the underarms, stomach, and other areas. The process is identical to treating women, though male hair is often coarser and may respond even better to treatment. Laser beard shaping is particularly popular for creating clean, defined beard lines.
6. What happens if I miss a session?
Life happens, and missing an occasional session will not ruin your results. However, consistency matters for optimal outcomes. If you miss a session, simply reschedule as soon as possible. Very long gaps between sessions may allow hair follicles to recover somewhat, potentially requiring additional treatments.
7. Can pregnant women get laser hair removal?
Laser hair removal is not recommended during pregnancy, not because of proven risks, but because there is insufficient research on safety during pregnancy. Hormonal changes during pregnancy also affect hair growth patterns, making treatment less predictable. Most practitioners advise waiting until after pregnancy and breastfeeding to resume treatments.
8. How long before a special event should I start treatment?
If you have a wedding, vacation, or special event planned, start your treatment course at least 6-8 months in advance. This allows time for multiple sessions and the natural hair shedding cycle. Avoid scheduling sessions in the two weeks immediately before a major event in case of any temporary redness.
9. Why are some clinics much cheaper than others?
Price differences in laser hair removal often reflect differences in equipment quality, practitioner experience, and treatment protocols. Very low prices may indicate the use of outdated IPL systems rather than true lasers, inexperienced operators, or cutting corners on safety. When it comes to laser treatments on your skin, choosing based solely on price can lead to poor results or complications.
