What's the best laser for dark hair on Fitzpatrick 4 to 6 skin?

Nd:YAG laser (1064 nm wavelength) is the safest laser for darker skin.  Shorter wavelength lasers such as alexandrite (755 nm) have a higher risk for burning pigmented skin.  Nd:YAG laser should work well for dark hair in patients with skin of color.  Make sure to see an experienced laser practitioner, preferably with a physician on site.Regards,Dr. Ort

Thanks for your question.  For darker skin type, you should probably seek out a laser vs. IPL to help avoid complications.  Almost all newer lasers are safe for all skin types and have features built in (such as sapphire cooling tips) to make them more comfortable.  Some of the newer technology is also more efficient, allowing for lower energy settings to be used with better results and less discomfort.  With modern equipment, your treatment should only be mildly uncomfortable, but not painful.  We never use numbing cream for LHR.  We want our patients to be able to tell us if they feel pain or an unusual level of discomfort.We recommend finding an experienced and reputable provider in your area with updated equipment.  A consistent overlapping technique is the key to avoiding patchiness in LHR.   Calibration and power of the laser is important for a safe, comfortable and effective treatment.  Find out what laser they will use and if it is under a maintenance contract.  If their laser isn’t calibrated on a regular basis or is underpowered, your treatment may be painful or inefficient. After a series of 6-8 initial treatments, you may need a touch up every 3-5 years.
