🔬 How Permanent Hair Removal Works and What Results to Expect
Permanent hair removal primarily uses Intense pulsed light (IPL) or the laser to destroy the hair follicle.
Key principles:
- The light is absorbed by the melanin in the fur
- The heat destroys the bulb without damaging the skin.
- Only hairs in the growth phase (anagen) are sensitive.
- Several sessions are necessary to treat all hairs at different cycles
💡 It is for this reason that the number of sessions varies by area and hair type.
📌 Factors That Affect Hair Removal Results (Skin Type, Hair Density, Area)
- Fur and skin color
- Dark hair + fair skin = best result
- Light hair or dark skin = longer sessions, risk of lingering.
- Hair cycle
- Each hair has 3 phases: anagen, catagen, telogen
- Only anagen phases are effective
- Treated area
- Thin, sparse areas: lips, chin, eyebrows
- Dense areas: legs, bikini line, back
- Method and apparatus
- Laser diode / alexandrite
- Intense pulsed light (IPL)
- Device quality and professional settings
- Monitoring and hygiene
- Adherence to post-session recommendations
- Soothing creams, light exfoliation
- Avoid sun and UV
📊 How Many Sessions Are Needed for Permanent Hair Reduction?
By zone :
| Zone | Average sessions | Recommended interval |
|---|---|---|
