Diode laser hair removal works by selectively targeting the pigment in hair follicles with laser light, effectively damaging the follicle and inhibiting future hair growth.
Here's a breakdown of the process:
-
Targeting Melanin: The diode laser emits a specific wavelength of light that is readily absorbed by melanin, the pigment responsible for hair color.
-
Light to Heat Conversion: When the laser light is absorbed by melanin within the hair follicle, the light energy is converted into heat.
-
Follicle Damage: This heat damages the hair follicle, particularly the structures responsible for hair regrowth, such as the bulb and bulge. The aim is to weaken or destroy the follicle to prevent or delay future hair growth.
-
Effective on Active Growth Stage: The treatment is most effective on hairs that are in their active growth phase (anagen). This is because the hair follicle is connected to the bulb and contains the most melanin during this stage. Because hair grows in cycles, multiple treatment sessions are needed to target hair in the anagen phase.
-
Delayed Regrowth: The damage to the hair follicle leads to delayed hair regrowth. Repeated treatments can result in significant and long-lasting hair reduction.
Here's a table summarizing the process:
| Step | Description |
|---|---|
| 1. Targeting | Diode laser emits light absorbed by melanin in hair follicles. |
| 2. Conversion | Absorbed light energy converts to heat within the follicle. |
| 3. Damage | Heat damages the hair follicle, inhibiting future growth. |
| 4. Growth Stage | Most effective on hairs in the active growth (anagen) phase. |
| 5. Repeated | Multiple sessions are needed to target all hairs in the active growth phase. |
| 6. Result | Delayed or prevented hair regrowth. |
The effectiveness of diode laser hair removal depends on several factors, including:
- Hair Color: Darker hair absorbs more laser energy, leading to better results.
- Skin Tone: Contrast between hair and skin color is important.
- Hair Thickness: Thicker hair typically responds better to treatment.
- Laser Type and Settings: Different lasers and settings are used based on individual characteristics.
Diode laser hair removal offers a long-term solution for unwanted hair by selectively targeting and damaging hair follicles, inhibiting their ability to produce new hair.
