What is a 810nm Diode laser hair removal?

The 810 nm diode laser, often grouped with 808 nm diode systems, is one of the most trusted technologies used in long-term hair reduction treatments across the United States. This wavelength is highly responsive to melanin, the natural pigment found in hair. During treatment, the laser energy is delivered directly into the hair follicle, where it focuses on the root without damaging the surrounding skin. By disrupting the follicle’s ability to produce new hair, repeated sessions lead to slower regrowth and, in many cases, lasting hair reduction.

Laser hair removal performed using an 810 nm diode laser is a proven treatment that delivers reliable results. It is suitable for treating unwanted hair across most areas of the body, making it a versatile option for long-term hair reduction.

This hair removal method is widely used because it allows practitioners to cover larger treatment areas quickly while delivering effective results with very little discomfort for the client.

Diode laser systems used for hair reduction are available in multiple wavelength options, including 755nm Alexandrite and 1064nm Nd:YAG. Each wavelength is designed to work best for specific skin types and hair characteristics. These technologies serve different purposes, which we will explain in detail in a separate article. 

USEFUL FACTS

• Wavelength: In laser technology, wavelength describes how far apart each wave peak is as the energy travels. An 810-nanometre wavelength is commonly used because it penetrates the skin effectively and is strongly absorbed by melanin, allowing the laser to damage hair follicles at their root and slow regrowth.

• Energy Density (Fluence): Fluence refers to how much laser energy is delivered over a specific area and is measured in joules per square centimetre (J/cm²). Proper energy levels are critical, as they determine how deeply the laser interacts with the tissue and directly influence treatment results.

• Pulse duration: Pulse duration, also known as pulse width, is the length of time the laser releases energy in a single pulse. Longer pulses can increase heat transfer to the follicle, but excessive duration may raise the likelihood of skin sensitivity or irritation.

• Spot size: Spot size defines the surface area treated with each laser pulse. Larger spot sizes allow practitioners to cover wider areas more quickly, although they must be carefully controlled to maintain safety and precision.

• Pulse Repetition Rate: The repetition rate indicates how many pulses the laser emits per second. Faster pulse rates can reduce overall treatment time, but overly high settings may increase thermal stress on the skin.

HOW DOES 810NM DIODE LASER HAIR REMOVAL WORK?

810nm diode laser hair removal works by delivering focused laser light directly into the hair follicle. The light energy targets melanin within the hair, generating heat that disrupts the follicle’s ability to produce new hair.

This specific wavelength penetrates deep enough to treat the root of the hair while remaining safe for the surrounding skin.

Because melanin absorbs the 810nm wavelength efficiently, the laser can precisely damage hair-forming cells without affecting nearby tissue.

Treatments are performed using controlled, short pulses of energy. This pulse system allows the follicle to heat gradually, reducing the risk of skin damage and improving client comfort during the procedure.

Some people may notice mild redness or swelling after treatment. These reactions are normal and typically fade within a short period, often within 24 to 72 hours.

Due to its balance of effectiveness and comfort, the 810nm diode laser is widely used for long-term hair reduction and consistent treatment results.

HOW MANY SESSIONS ARE NEEDED FOR LASER HAIR REMOVAL?

On average, most individuals require between 3 and 7 laser hair removal treatments to achieve the best results. The exact number of sessions can vary depending on hair type, growth cycle, and individual response to treatment.

• Laser hair removal targets the cells responsible for hair growth, and this process does not produce instant results. Because the treated hair follicles are gradually weakened, visible changes often appear over time rather than immediately.
• It is common for hair in the treated area to keep growing for a few weeks after a session. This happens because the affected hairs need time to loosen and naturally fall away from the skin.
• Sticking to the recommended treatment intervals is essential. Proper spacing between sessions allows the laser to work more effectively and helps deliver longer-lasting results.

It is equally important to consider the quality of laser hair removal machines as correct handling and technique by the practitioner play a major role in treatment effectiveness.

After diode laser hair removal, most people find the recovery process easy to manage. Following proper aftercare helps protect your skin and improves overall results:

1. Limit sun exposure: Keep the treated area out of direct sunlight for about 7 days. If going outdoors is unavoidable, use a broad-spectrum sunscreen with SPF 30 or higher and reapply as needed.
2. Skip heat for 24 hours: Avoid hot showers, steam rooms, saunas, and hot tubs for at least one day, as heat can increase skin sensitivity.
3. Take a break from workouts: Intense exercise should be avoided for the first 24 hours. Excessive sweating can irritate the skin and slow down recovery.
4. Be gentle with skincare products: Do not apply products containing alcohol, strong fragrances, or harsh ingredients on the treated area for at least a day.
5. Soothe with cooling: Mild redness or tenderness can be relieved by placing a cold pack or cool compress on the area for short periods.
6. Allow skin to heal naturally: If small scabs or blisters appear, do not scratch or pick them. Letting the skin heal on its own helps prevent marks or scars.

Always make sure you carefully follow the post-treatment guidance given by a licensed and trained professional, as proper aftercare plays a key role in safe recovery.
