Kiierr Laser Cap Models

Kiierr offers two laser cap models: the 148 Pro and the 272 Premier Laser Cap.

The Kiierr148Pro and the Kiierr 272 Premier Laser Cap are pretty similar. They have a similar design, advanced laser technology, convenience features, flexibility, and operating modes. The two models share certain features suitable for treating mild Alopecia or new hair loss and severe hair loss.

However, the Kiierr 148 Pro (148 laser diodes) has narrower coverage than the Kiang 272 Premier (272 laser diodes); it would be more suitable for treating mild Alopecia or new hair loss. Furthermore, because there are more lasers in the 272 Premier model than its counterpart- only 148- it would be more suitable for treating severe hair loss or baldness cases. The more substantial output of this model also provides a faster treatment effect. 

To treat extreme hair loss cases, we recommend using the complete system. It includes a Hair Growth Vitamin (the cap alone doesn’t offer enough vitamin), shampoo, and conditioner to make sure each step is effective in helping you achieve better results!

Frequently Asked Questions (FAQ):

How to treat Alopecia or hair loss?

Hair loss is one of the most common problems people experience. It can happen to anyone and any time, even if they have no hereditary baldness. Many predisposing factors can cause you to lose hair, but the most common cause of baldness is genetic male and female-pattern baldness.

Other causes include using certain medications, sex hormones, surgeries, or other illnesses to trigger Alopecia.

There are three main ways to treat hair loss: using medicines, surgery, and low-level laser therapy devices like the Kiierr Laser cap. Using medicine is the most common way to treat hair loss; however, side effects are more likely with higher doses of this type of medication.

It’s also important to be aware that there is no Guaranteed Success when it comes to hair transplant surgery. The best option may not be the one you decide on!

What is Low-Level Laser Therapy for hair?

Low-level laser therapy, or LLLT (light radiation therapy), is a type of hair treatment that involves low-powered wavelength-tuned laser light. It can be done on the skin, as in sunburn, or directly to the scalp using a light cap. Low-level lasers are incredibly safe and noninvasive; the FDA clears them to treat various medical conditions.

They’re especially effective for treating androgenetic Alopecia – while the laser light has little impact on the hair itself, it has an immediate positive effect on the body’s reaction to hair growth! Laser growth caps are one way to receive LLLT for hair growth – make sure you have considered this option before!

How Kiierr LLLT Cap Works?

With Kiierr laser caps, you can safely and effectively treat scalp hair with low-level light therapy (LLLT). This type of treatment is used to penetrate through medical-grade laser diodes to provide essential nutrients and oxygen to the follicles, reducing inflammation and promoting healthy hair growth. In four to eight weeks after undergoing this procedure, you will see visible hair growth! 

The study found that almost half of those who had used a previous laser treatment or trichology treatment saw better results with the laser treatment. There is also an option for those who don’t want to wear a wig using Kiierr lasers cap.

How to use the Kiierr laser cap?

Step 1: Unpack the charger and connect the charger to the power pack. Use only the portable battery included in the kit, and do not use it directly into a wall outlet. Please fully charge in advance.

Step 2: Place the cap module on the ball cap. Place the Kiierr Laser Hair module in the included black ball cap or standard ball cap of your choice.

Step 3: Connect the USB power adapter and laser hair cap module. Make sure the USB cable is fully inserted in the cap. The USB may be upside down, so do not force it.

Step 4: Put it on your head and then put the cap on. When on, the device flashes and turns off automatically after 30 minutes. Be careful not to look directly at the laser.

Depending on the severity of hair loss, this cap should be used daily for at least 6 months.

How long does a Kiierr laser cap take to work?

Even with these laser caps, you may not get immediate results overnight or after a few days. It takes time to clean from the inside of the hair, so it cannot be done immediately.

Not all clients succeed with cap treatments but on average monthly treatments.

It may take some time to get the same result if you damage your hair, redness, white spots, or fine hair.

Treatment with the Kiierr laser cap should last 4-12 months every other day. You can then maintain your hair quality by continuing one or two sessions a week.

The Kiierr Laser Cap has been found to be reasonably priced and an excellent device for those who have too fast a hair growth cycle.

As a result, it is ideal for preventing unwanted hair growth and treating hair growth.

Is it safe or has side effects?

Kiierr uses a low-level laser beam of 560nm that does not harm the skin or scalp.

No side effects have been reported at this time, but caution should be exercised when using a laser around the eyes. Please do not turn the cap before wearing it.

“I’ve been using the Laser Cap for six months. Not sure if I see improvement in hair growth. I “think” there “may” be but can’t quite tell yet. Will continue to use a while longer to give Laser Cap a fair shot. Everyone’s hair growth is different.”

“Since it is too early to tell whether the system works, I can only address the comfort and ease of use. You only wear the cap every other day for 30 minutes, take the supplements twice a day, and use the shampoo and conditioner daily. But you have to have patience because they say you may not see results for 6 months.”
