Understanding Laser Hair Removal
The Effectiveness of Laser on Different Skin Types
Professional laser hair removal procedures consider the Fitzpatrick skin types scale, which helps determine the specific skin type’s response to laser treatment. The following table shows the Fitzpatrick scale for skin types and their response under heat:2
Specific Lasers for Different Skin Types |
||
| Laser Type | Energy Emitted (nm) | Skin Type & Other Characteristics |
| Rube Laser | 694 | Red light, delivered through synthetic ruby crystals, is more effective for lighter skin types I-III. |
| Alexandrite Laser | 755 | It is ideal for skin types I to III due to its greater penetrance |
| Diode Laser | 810 | It penetrates deeper, delivers better fluency, less epidermal damage, safer in darker skin I-V |
| Neodymium-doped Yttrium-Aluminium-Garnet (Nd: YAG) Laser | 1064 | It has better penetration and is less likely to cause epidermal damage. It can be used on skin types I to VI |
| Intense Pulse Light (IPL) or Broadband Light (BBL) | 500-1200 | This laser can be used on darker skin and covers larger areas due to its larger spot size. It is less expensive than a true laser but also less effective. It is most preferred for fair skin types with dark hair. |
The Effectiveness of Laser on Different Hair Types
Contrary to popular belief, the color and thickness of hair significantly impact the effectiveness of laser hair removal treatment. Since the laser uses light energy to damage the hair follicle (which can only occur if it can absorb heat), your professional must assess your hair type during consultation. This evaluation ensures the treatment is tailored to your needs, maximizing its effectiveness. Mentioned below are some of the common patterns seen in various individuals with differing hair types:- Individuals with thick, coarse body hair are said to achieve the most favorable results, as the laser can effectively target the melanin-rich hair follicles.
- Conversely, individuals with light-colored, blonde, or vellus hair may not achieve similar results due to the lower melanin content in their hair follicles, which makes them less responsive to laser targeting.
- The ideal candidates for laser hair removal are those with lighter skin types and dark body hair. This combination contrasts the skin and hair, allowing the laser to target and damage the follicles quickly.
