Dark skin and light hair: what light-based hair removal can do
In short
Does light-based hair removal work on dark skin and on light hair?
On dark skin, yes, if the device and the protocol are made for it. On very light, grey and white hair, the possibilities are limited. Light-based hair removal works through melanin: the pigment in the hair absorbs the light and turns it into heat. The skin also contains melanin, and the darker the skin, the more it competes with the hair. That is why dark skin needs a suitable wavelength range, cooling and energy delivered in portions. The IPLASER 755 handpiece of iPRO MINI works on skin types I–VI, in the 755–1064 nm range, with three short pulses per flash. Hair with little pigment responds more weakly: according to Innovatione, light hair takes 8–10 treatments instead of 6–8 for dark hair. Grey and white hair have almost no melanin, so light-based methods have little to work with, and the client should hear this honestly at the consultation.
IPLASER hair removal: skin types I–VI, protocol by skin type
Why do skin and hair colour matter?
Light-based hair removal targets melanin. The pigment in the hair absorbs the light, and the heat it produces acts on the follicle. The skin around it contains melanin too. The more pigment there is in the skin, the more light it absorbs, and the less energy can safely go to the hair.
So two things decide the parameters: how dark the skin is and how much pigment is in the hair. The easiest case is dark hair on light skin. The hardest are dark skin, where the skin competes with the hair, and light hair, where there is little to absorb the light.
What is the Fitzpatrick scale?
| Type | Skin | What it means for the treatment |
|---|---|---|
| I | Very fair, burns easily in the sun | High contrast with dark hair |
| II | Fair | Similar to type I |
| III | Medium | Standard protocols for most areas |
| IV | Olive | More melanin in the skin, parameters chosen with more care |
| V | Brown | A suitable wavelength range and careful energy delivery |
| VI | Dark brown to black | The same, plus a test flash and careful observation |
The specialist assesses the skin type at the consultation, and the protocol sets the parameters for it. This is covered in training.
What works on dark skin?
- The wavelength range. Longer wavelengths are absorbed less by the melanin in the skin. More in the article on 755, 808 and 1064 nm.
- Cooling. The surface has to stay cool while the heat reaches the hair. See handpiece cooling.
- Energy in portions. When the flash is split into short pulses with pauses, the skin cools down between them. See three-pulse energy delivery.
- A test flash and observation, especially for darker skin types and after the summer.
What about light, red, grey and white hair?
Hair with little pigment absorbs little light, so it responds more weakly and needs more treatments. According to Innovatione, light hair takes 8–10 treatments instead of 6–8 for dark hair, at intervals of 6–8 weeks. The IPLASER 755 handpiece also works with fine hair that has little pigment.
Grey and white hair have almost no melanin left, so light-based methods have little to work with, whatever the device. It is better to say this at the consultation than to sell a course that will not deliver.
How to talk to the client
- Assess the skin type and the hair colour at the consultation and write them down.
- Check the contraindications, including a fresh or intense tan.
- Explain how many treatments the protocol plans for this skin and hair, and why light hair takes more.
- Do a test flash where the protocol requires it.
- Take before photos of the area, so that progress can be compared honestly.
How results look over a course of treatments is shown in 155 before and after photos.
Questions and answers
Can dark skin be treated with IPL?
Yes, if the device and the protocol are made for it: a suitable wavelength range, cooling and energy delivered in portions. The IPLASER 755 handpiece works on skin types I–VI.
Why does light hair need more treatments?
It has less melanin, so it absorbs less light. According to Innovatione, light hair takes 8–10 treatments instead of 6–8 for dark hair.
Does light-based hair removal work on grey hair?
Grey and white hair have almost no melanin, so light-based methods have little to work with. Say this honestly at the consultation.
What is a test flash?
A single flash on a small area before the course, to see how the skin reacts. The protocol says when it is needed.
Can a client with a tan be treated?
An intense tan is a contraindication. The specialist decides at the consultation and may postpone the treatment.
