Here are a few of the most common questions we get:

Q: What is LLLT, and how does it work for hair growth?

A: LLLT is an acronym for Low-Level Light Therapy. It refers to a therapy that uses laser or light energy below a specific energy threshold and within a specific wavelength. Light sources used for LLLT may include laser and LED devices. Laser devices used for LLLT are also referred to as cold lasers. LLLT devices are safe. They produce no heat and cannot burn or injure the skin.

Hair is constantly growing, resting, and then shedding the old hair shaft before growing again. With pattern hair loss, the hair becomes progressively thinner and lighter in color with each growing cycle. The cycle keeps repeating until the hair follicle is atrophied. Low-level laser light therapy improves cellular respiration so that hair stays in the growth phase longer, reducing the duration of the dormant stage. This results in the hair growing back thicker and darker, with the hair loss being reversed, stopped, or slowed down. LLLT is not recommended for people with light sensitivity.

Q: Does Kiierr/LLLT work for both men and women?

A: Yes. Both men and women, ages 18 to 80, have experienced great results from LLLT. LLLT devices are not recommended for people with light sensitivities.

Yes, the Kiierr272Premier system requires no manual effort. Simply place the cap on your head, turn it on and enjoy your new hair growth. Our cap fits up to 23.5′′ in circumference. We also carry the Kiierr MD cap, which is like the top of the line. Ask us for more info.

Q: How soon until I see results, and when should I register my device for the warranty?

Results vary depending on the degree of hair loss when you begin. Hair growth starts at the cellular level. After using the Kiierr272Premier Cap as directed, the majority of users typically report visible changes in four to seven months. Hair becomes thicker, fuller, and healthier in approximately seven months in most cases. You should register your product within the first 45 days of receiving your device.
