What Is Laser Hair Removal? A Dermatologist's Complete Guide
Laser hair removal is a medical procedure that uses concentrated light beams to remove unwanted hair by targeting and destroying hair follicles. It's one of the most popular cosmetic treatments worldwide, offering long-term hair reduction for areas like the face, legs, arms, underarms, bikini line, and more.
As a dermatologist who has performed thousands of laser hair removal treatments, I can tell you it's a safe, effective solution when done properly by trained professionals. This comprehensive guide covers everything you need to know—from how it works to cost, benefits, risks, and what to expect.

How Does Laser Hair Removal Work?
Laser hair removal works through a process called selective photothermolysis. Here's what happens during treatment:
-
Light Absorption
The laser emits a concentrated beam of light that's absorbed by the melanin (pigment) in the hair shaft.
-
Heat Conversion
The absorbed light energy converts to heat, traveling down the hair shaft to the follicle.
-
Follicle Damage
The heat damages the hair follicle, inhibiting its ability to produce new hair growth.
-
Hair Shedding
Over 1-3 weeks, treated hairs fall out naturally as the damaged follicle releases them.
"Laser hair removal is a game-changer for people tired of constant shaving, waxing, and ingrown hairs. With the right technology and expertise, we can achieve 70-90% permanent hair reduction for most patients." — Dr. Alekya Singapore

Frequently Asked Questions About Laser Hair Removal
Is laser hair removal permanent?
Laser hair removal provides long-term hair reduction, but it's not 100% permanent. Most people experience 70-90% permanent hair reduction after completing their sessions. Some hair may regrow over time, but it's usually finer and lighter. Annual maintenance sessions help maintain results long-term.
How much does laser hair removal cost in Hyderabad?
Laser hair removal cost in Hyderabad varies by treatment area: Upper lip costs ₹1,500-3,000 per session, underarms ₹2,500-5,000, full legs ₹8,000-15,000, bikini area ₹4,000-8,000, and full body ₹15,000-35,000 per session. Most people need 6-8 sessions for optimal results. Consult for personalized pricing.
Does laser hair removal hurt?
Most people describe laser hair removal as feeling like a rubber band snapping against the skin. Modern lasers have cooling mechanisms that minimize discomfort. Pain tolerance varies by individual and treatment area—sensitive areas like bikini line may feel more uncomfortable than arms or legs. Numbing cream can be applied for sensitive patients.
How many sessions do I need for laser hair removal?
Most people need 6-8 sessions spaced 4-6 weeks apart for optimal results. Hair grows in cycles, and laser only targets hair in the active growth phase (anagen). Multiple sessions ensure all hair follicles are treated. Some areas may require more sessions, and annual maintenance sessions help maintain results.
Who is a good candidate for laser hair removal?
Ideal candidates have dark hair and lighter skin, as the laser targets melanin (pigment) in hair. However, modern technology like Nd:YAG lasers makes treatment safe for darker skin tones too. Not recommended for: pregnant women, those with active skin infections, people on photosensitizing medications, or those with very light/white/gray hair (lacks melanin for laser to target).
What are the side effects of laser hair removal?
Common temporary side effects include redness, swelling, and mild irritation (resolves within hours to days). Rare side effects include blistering, pigmentation changes, or scarring—usually from improper settings or untrained operators. To minimize risks: choose a qualified dermatologist, follow pre/post care instructions, and avoid sun exposure before and after treatment.
Can I do laser hair removal at home?
At-home IPL devices are available but are less powerful than professional lasers. Professional treatment offers: stronger results, customized settings for your skin type, safety oversight by trained specialists, and better long-term outcomes. At-home devices may work for maintenance but typically require more sessions and provide less dramatic results.
