Although hair growth laser combs have proven to be safe and effective for dealing with hair loss, of course, there are some things you should pay attention to before using them. You must also be careful when you want to use some other types of laser hair growth devices.
The first is that you are not advised to use this laser comb when you are undergoing treatments that are photosensitizing. These treatments cause certain chemical reactions in the body, which makes the skin more sensitive to light.
In addition, the safety and long-term effects of this tool have not been further investigated. All laser devices, including hair growth laser combs, are classified as medical devices by the Food and Drug Administration (FDA).
For this reason, laser therapy devices do not have the same level of supervision and testing that is found in drugs before they are approved. In addition, the use of this laser is less effective for those who have advanced hair loss than those in the early stages.
