How Laser Hair Removal Works

Laser hair removal uses light energy to target the pigment in your hair follicles. The darker the hair, the more pigment it has, which makes it easier for the laser to find and treat.

Concentrated light from the laser damages the follicle enough to eliminate regrowth. It weakens the hair’s ability to grow back and only hairs in the active growth phase respond to treatment. 

Laser Hair Removal Requires Multiple Treatments

Hair grows in cycles, not all at once, which is why multiple laser treatments are necessary for full coverage. Some follicles are active while others are resting or preparing to shed, which means a single session can't address every hair on your body.

Not all hair follicles can be treated at once. Dormant or transitional hair won't absorb enough energy to be affected, so you need multiple sessions to target hair as it cycles into its growth phase.

Treatments are spaced approximately five weeks apart to align with your hair growth cycle. This timing ensures you're catching new hair as it becomes active, not just retreating the same follicles over and over.

Laser Hair Removal Reduces Hair Growth Over Time

Hair becomes finer and grows more slowly after each treatment. The change is gradual. Regrowth gets lighter and less noticeable as you progress through your sessions.

You won't see complete results immediately. It takes several months of consistent treatments to achieve significant reduction, and even then, some areas may respond differently based on hormones or hair characteristics.

Occasional maintenance may be needed. Hormonal shifts or new follicle activation can trigger sporadic regrowth, so touch-ups help keep results consistent over time.

Laser Hair Removal Provides Lasting Results

Most people see permanent hair reduction after completing their treatment plan. Hair that does grow back is typically finer, lighter, and slower to appear than before you started, making laser one of the most effective hair removal methods available.

The results are permanent. Still, hormones, genetics, and how consistently you follow your treatment schedule all influence how much hair stays gone and how much might return over time.

Some people need occasional maintenance treatments. Touch-ups address any new growth triggered by hormonal changes or follicles that weren't fully treated during your initial series of treatments, keeping your results smooth and consistent. At Milan Laser, that’s where our Unlimited Package ™ is a significant benefit. You pay one price for a body area instead of having the ongoing cost of paying session by session. 

Safety Facts About Laser Hair Removal

Laser hair removal is generally safe when performed by trained providers. The laser procedure has been used for years and is well-studied, but outcomes depend heavily on who's doing the treatment and how they're using the equipment.

Symptoms like redness, swelling, or mild discomfort are usually temporary, though avoiding sun exposure before and after treatments helps minimize irritation. Most people experience minor sensitivity right after treatment, but it fades within hours or a few days as your skin settles.

Proper technology and settings matter. Using the right laser device for different skin types and hair color, along with appropriate energy levels, reduces the risk of burns, irritation, or ineffective results. Not all providers use the same equipment or protocols, which is why oversight and training are critical.

What Laser Hair Removal Does Not Do

Laser hair removal does not work on white or gray hair. The laser targets pigment in the follicle, so hair without color can't absorb the light energy needed for treatment.

It does not treat skin conditions like eczema, keratosis pilaris, or hyperpigmentation. While reducing hair may improve the appearance of some skin texture issues like ingrown hairs, the laser itself isn't designed to address medical or dermatological concerns.

Laser hair removal does not affect your internal organs. The light energy only penetrates deep enough to reach the hair follicle near the skin's surface, whether treating legs, underarms, or the bikini line, and doesn't interact with anything beneath that layer.

Why Results Vary From Person to Person

Several factors influence how quickly you see results and how much hair reduction you ultimately achieve:

• Hair color and thickness: Dark, coarse hair responds best because it contains more pigment for the laser to target. Fine or light hair may require more sessions or show slower progress.
• Skin tone and sensitivity: Laser settings are adjusted based on your skin type, from light skin to darker tones, to balance effectiveness and safety. 
• Hormones and genetics: Conditions like PCOS, thyroid disorders, or natural hormonal fluctuations affect hair growth patterns. Your body's unique biology plays a major role in how well and how quickly you respond to treatment.
