When it comes to laser hair removal, there is no need to worry if you have a tattoo in the same area. However, it is best to wait until the treatment is complete, as it usually takes 6 to 8 sessions with one or two weeks between each session. Destructive lasers have been used to remove white, brown, or brown pigments from tattoos that are resistant to removal with Q75 switching lasers. This type of laser removal often causes scarring and may not be able to completely remove a particular tattoo in one go.
In some cases, a combination of all three types of Q-switched lasers may be necessary. The Q-shaped ruby laser was the first laser developed to treat pigment lesions and tattoos.Hair loss (especially on the face) may be observed after treatment, as the damaged hair follicle usually sheds during the first week. When a large spot is used, the smallest percentage of the incident laser beam will be scattered, thus minimizing the percentage of the laser beam that is placed superficially on the skin. The continuous argon laser produces a scarring appearance similar to that seen after carbon dioxide laser treatment on treated tattoos.
Of the professional tattoos that were treated, 2 managed to completely remove them, 5 were almost completely removed, 18 were significantly removed, and 25 had minimal removal with little extraction in 12. The exceptions to this case are tattoos that are small enough to be easily removed and those in which a person has an allergic reaction, which are dangerous to remove with any type of laser. Long-term results suggest that the 800 nm pulsed diode laser is very effective in removing dark terminal hair. As early as 1965, Q-switched lasers were used to remove pigments from tattoos. Goldman demonstrated that the Q-switched ruby laser interacted with the dark pigments in tattoos and removed them without leaving a scar.
Temporary hair loss (1 to 3 months) always occurs after laser treatment, regardless of the color of the hair or the device used. Lasers have also been used to remove tattoos non-selectively by heating and destroying tissue since the 1970s.
