Is the Kiierr272Premier Laser Hair Growth Cap fully automated?
Yes. The Kiierr272Premier system requires no manual effort. Simply place the cap on your head, turn it on and sit back, relax and enjoy your new hair growth.
How soon until I see results?
Results vary depending on the degree of hair loss when you begin. Hair growth starts at the cellular level. The majority of users, after using the Kiierr272Premier Cap as directed, typically report visible changes in four to five months. Hair becomes thicker, fuller and healthier in approximately six months in most cases.
Do I need to wash my hair or use a special shampoo before using my Kiierr272Premier Cap?
Please use your normal shampoo to keep your hair and scalp clean and free of excess oil.
How does Low Level Laser Light Therapy work for hair growth?
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.
Is an increase in shedding normal when first using the Kiierr272Premier Laser Cap?
Yes. That can happen. It depends on variables, such as your individual hair type. But not to worry—it’s a temporary situation.
What is LLLT?
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.
How does LLLT work?
Multiple clinical studies have shown the effectiveness of Low Level Light Therapy in promoting hair growth in men and women with androgenetic alopecia. The most recent research has found that LLLT is absorbed into the cells, triggering enhanced cellular activity. In other words, LLLT energizes aging cells and stimulates the production of hair.
Are there any medical studies (clinical trials) that support the use of LLLT for hair growth?
Yes! Please see our page on LLLT clinical studies here
Do physicians advise the use of LLLT for hair growth?
Yes. Medical doctors, including dermatologists, in the United States, Europe and Asia have been prescribing LLLT for patients suffering from androgenetic alopecia for many years.
How does wavelength affect LLLT for hair loss treatment?
It is important to use light within the recommended wavelength for laser hair growth treatment. Research and studies consistently suggest that the most effective wavelength for hair growth is between 650-670nm. This wavelength range provides the most efficient and effective rate of absorption that is essential for hair growth.
Will all laser and light devices provide equivalent results?
No. Devices differ in power and energy output and, therefore, results will differ. Many devices cover only a limited area. There are devices that require the user to manually move a comb or brush repeatedly over the scalp for 15-30 minutes at a time. This is not only a tiresome process, it does not provide the necessary consistent application of the light. The Kiierr272Premier hair growth system is hands-free, completely automated, easy to use and concealed in a standard ball cap. Each 30-minute treatment session provides the most consistent scalp coverage on the market today.
Can LLLT be used with treatments such as Rogaine or Propecia?
Yes. However, keep in mind that the use of pharmaceuticals is not required to achieve results with the Kiierr272Premier Cap. That’s what’s great about Kiierr technology!
Can Kiierr Laser Caps be used if I am using other hair treatments?
Yes. Other treatment options for hair loss work by completely different mechanisms. You can continue using them while using Kiierr. The combination may provide additional benefits. Many hair transplant surgeons recommend LLLT after surgery to improve healing. Please consult the surgeon before using Kiierr.
I’ve had hair transplant surgery. Is there a benefit to using the Kiierr272Premier?
Yes. In a hair transplant, hair follicles are taken from an area of your scalp where hair growth is thickest (usually the back of the head) and transplanted into the area with thinning hair. Initially, the thickness of the hair is greatly improved. However, the “un-transplanted” hair continues to thin and fall out, and you have thin hair again. You may need more transplant surgery. The Kiierr272Premier LLLT cap can maintain the health of your hair, thus reducing or eliminating the need for subsequent transplants.
Are there other low level laser therapy treatment options available for hair loss?
Yes. The original FDA-cleared LLLT device for hair loss was a hand-held comb with 9 laser diodes. The user must comb the device through the hair for 15 minutes 3 times a week. The second FDA-cleared device was an in-office hood with 90 bulbs. The user goes to a clinic and sits under the hood three times a week. The Kiierr272Premier Laser Hair Growth Cap uses the same laser diodes as those two devices. However, the Kiierr272Premier Laser Cap has 272 diodes, providing consistent, full coverage to the scalp. More importantly, the Kiierr272Premier Cap is much more user-friendly and time-efficient. It is the original hands-free device that allows you to continue your normal activities while receiving the treatment. No trips to an expensive clinic needed! In addition, the Kiierr272Premier Cap requires only a one-time investment.
Does Kiierr/LLLT work for both men and women?
Yes. Both men and women, ages 18 to 80, have experienced great results from LLLT.
I just noticed that my hair is thinning. Is it too soon to start LLLT sessions? If so, when should I start?
The Kiierr hair growth system is intended for use by men and women afflicted with androgenetic alopecia. LLLT hair treatment can incorporated into your weekly preventive maintenance routine to preserve and strengthen existing hair and provide a healthy environment for continued growth.
Do you ship internationally?
We can ship to most parts of the world. Applicable shipping rates will vary.
Why should I use Kiierr rather than go to a clinic?
The Kiierr system is one of the most powerful and comprehensive hair growth systems developed for at-home use and has an equivalent or better output as compared to most in-clinic lasers. There is no contest in convenience. You can use the Kiierr system at home, in the office, driving—wherever, whenever you want!
I am completely bald and want to use Kiierr. Will it work for me?
The Kiierr system is not recommended for those with severe hair loss.
How long will I need to continue LLLT sessions?
Hair loss is a progressive condition. If untreated, you can expect to lose more hair over time. After the initial LLLT treatment period (four to six months), you should continue sessions once or twice per week to maintain hair quality.
If three to four sessions a week provide good results, will more frequent sessions yield better results?
There is no evidence that increased LLLT sessions provide better results. It is important that LLLT be used as prescribed: Each session followed by a period of rest, i.e., use every other day.
How do I use the Kiierr272Premier Laser Hair Growth Cap?
Firstly, fully charge the battery pack while in the off position. Secondly, put the Kiierr272Premier Laser Cap insert into the Kiierr hat provided or any hat you desire. Lastly, connect the battery pack to the Kiierr272Premier Laser Cap Insert and turn on the power switch. Then, wear your cap per your user manual’s instructions.

Is LLLT safe to use for a pregnant or nursing woman?
Please contact your physician for individual guidance.
At what age is it safe to start LLLT?
LLLT is effective in men and women ages 18 and older. Please consult your physician if you are under the age of 18 or if you have any adverse health condition that concerns you.
What about eye safety?
