Laser Cap (LLLT) Pros and Cons

Laser caps are currently one of the safest and most effective hair loss treatments available on the market. Laser caps rely on low-level laser therapy (LLLT) to produce their results. Low-level laser light therapy is a treatment in which laser light is shown onto the scalp in a specific wavelength and frequency. Photons from the laser light are absorbed by the hair follicles and it stimulates them to start functioning at a higher level and producing longer, thicker hair. 


Although this treatment is very popular for hair loss, some people hesitate to use it because they are not fully aware of all of the pros and cons. In this article we will break down all of the pros and cons of LLLT and laser caps that you need to be aware of.

Is LLLT Right for You? 


As you can see from the list above there are not that many downsides to low-level laser light therapy. For this reason, it is a great option for many people who have hair loss to try. Because there are no known serious side effects of LLLT, there are very few reasons not to give this hair loss treatment a try. For some people, the initial investment made to purchase a laser cap results in a tremendous boost in hair growth in the 3-7 months that follow when they start using the device. If you decide to try LLLT therapy, there are some laser cap manufacturers that allow complete money-back guarantees if you are not happy with the results after a certain amount of time. 

Getting Started 


To get started with LLLT for hair loss, you will need to purchase a laser cap, laser helmet, or another similar device. Once you buy the device, you will have to use it as the manufacturer recommends. Often times this is in a frequency of a few times a week for about 20 to 30 minutes per session. Once you start doing this, you should be able to know within a few months whether or not it is going to have any hair loss benefits for you. You should take a picture of your scalp before you start the treatment so that you will track your progress. If you do not know which LLLT device to use, Kiierr offers high-quality laser caps for reasonable prices.
