The common lasers used for hair removal are:

 Ruby Lasers

This is a shorter wavelength of 694 nm. This is ideal for light and thin hair, and smaller treatment areas. This is not recommended for darker skin tones.


This stands for intense pulse light, so technically it’s not a true laser!! These aren’t very effective to treat hair removal and are commonly associated with burns/ hyperpigmentation especially in darker skin tones. IPL’s may require a lot more treatment sessions than a laser would need. Advantage is these could be priced lower than lasers.

Alexandrite Laser

This is a shorter wavelength at 755nm, which is good for Lighter skin tones. This is a fastest laser so can cover larger areas quicker, the flip side is this is the least comfortable for laser hair removal.

Diode Lasers

The wavelength here is 800-810 and penetrates deep into the hair follicle. These are relatively new lasers. These are better for dark/ thick hair. hence popular to treat men’s hair in the chest/ back. These are safe for most skin types.

 NdYAG Lasers

These are the most advanced lasers with the latest technology. The wavelength here is 1064nm. These are very safe and effective on all skin types, especially on colored skin tones. This treatment has no downtime.
