Permanent hair removal with the alexandrite laser (2024)

FAQs

Permanent hair removal with the alexandrite laser? ›

Here a wavelength of 755nm is used. The colour pigments in the hair root absorb the emitted bundled light. Due to its high energy the hair root is destroyed and the regrowth of a new hair is prevented. This way a permanent* result can be achieved.

For laser hair removal, the most popular devices are those using Diode, Alexandrite, Nd:YAG and IPL technology. These provide the safest and most effective results for permanent hair reduction.

Effective treatment of light coloured fine hair requires a laser with a high attraction to melanin such as the Alexandrite 755nm laser. Darker thicker hairs will respond better to the diode 810nm laser or Nd Yag 1064nm laser.

Alexandrite works using a combination of light and heat, this light is attracted to and absorbed by melanin. Melanin is the substance within your hair that contains the pigment or colour. This is definitely the most important factor for laser on pale/medium skin types.

CONS of the Alexandrite Laser System: The Alexandrite laser system is more painful than other systems and can cause discoloration if used on patients with darker skin tones.

Shave prior to your laser treatment

Ideally, you should shave 12 hours before coming to your hair removal appointment. Be sure to use a clean new razor before your appointment so no bacteria that can cause contact dermatitis can linger after your treatment.

One great thing about this treatment is that it's effective at any age. Whether you are 19 or 89, this treatment is the best way to permanently reduce your hair. The best time for you to seek treatment is whenever you realize that you have unwanted hair that you would be happier without.

Diode lasers are typically more effective for individuals with darker hair and fair skin, while alexandrite lasers are more versatile and can be used on a wider range of skin types and hair colors. Another factor to consider is the treatment area.

Laser(Alexandrite and ND:Yag) Overview: Long pulsed lasers are used for the permanent reduction of unwanted body hair and are safe for all skin types. A series of treatments is needed to achieve the degree of reduction a person feels comfortable with.

Is Alexandrite better than IPL? ›

*Unlike the IPL laser, technology like the Alexandrite laser uses a single, precise wavelength, to target the melanin the hair follicle exactly, so there is no 'hit and miss'. *This exact wavelength leads to a more effective treatment than IPL hair removal and therefore fewer treatments in the long term.

Alexandrite Laser downtime

There is no real downtime associated with Alexandrite Laser treatment. The treated areas will become dark and rough and may be sensitive for up to a week as they heal. In order to avoid unintended scarring, it is essential not to pick at scabbing or wash the area too vigorously.

Ideally 24 hours, but if you must shower wait at least 6-8 hours after your session. Use tepid water and avoid using any harsh products, scrubs, exfoliating mitts, loofahs or sponges on your treatment area. Use an unscented body wash and pat dry your treatment area with a towel to avoid damaging the skin.

To remove the hair, most patients need 2 to 6 laser treatments. After finishing the treatments, most patients do not see any hair on the treated skin for several months or even years. When the hair regrows, there tends to be less of it.

Usually, it takes around 6- 12 sessions for a successful laser hair removal treatment to completely get rid of the unwanted hair. Your dermatologist will be able to give you a fair idea of the sessions you may require for the treatment.

This varies, depending on the area you're treating, how coarse the hair is, and how responsive it may be. Expect between six to ten sessions for a 90% reduction in unwanted hair. It sounds counterintuitive, but darker, coarser hair often requires fewer sessions.
