Our Experience With Kiierr 272 Premier MD Laser Cap

A proven laser hair cap to regrow hair is the Premier MD 272 from Kiierr and it is our choice for best overall laser hair cap.

Overall, the device has amazing features such as medical-grade lasers, automatic treatment timers, and a fashionable design. 

In terms of lasers, the Kiierr laser cap comes with 272 laser diodes! That is the most of any device on the hair growth market. These lasers are fitted into a baseball cap to give you complete scalp coverage on the go.

When we compared hair regrowth results between the Kiierr and other devices with less lasers, the Kiierr laser cap was able to produce visible results relatively faster.

When it comes to design, would you rather have an obvious and nerdy device on your head or something more discreet that no one would notice. We would prefer the latter. And that is how the Kiierr is designed. You can get laser treatment on the go with the look of a regular baseball cap.

The Kiierr Premier MD is an upgrade to the Kiierr Premier laser cap. This model includes an upgraded battery and more head space in the hat.

The Hairmax PowerFlex laser cap is our choice as the best laser hair cap for power due to its cutting edge 282 medical strength lasers.

illumiflow Pro Laser Cap


  • Light enough to carry and easy to use
  • Extra safety with auto shut-off feature
  • Hat covers entire scalp
  • Helpful customer service


  • Laser cap tends to fall easily when moving around
  • Substandard design
  • 30 minute treatment session

Our Experience With illumiflow 272 Pro Laser Cap

Another excellent option for thinning hair is the illumiflow Pro 272 laser cap. This cap comes with cool laser technology and an auto shut-off timer to make treatments less painful for you.

The illumiflow hair loss treatment for hair growth is our choice for the fastest laser cap. This is because it has hundreds of medical grade lasers and produces light at an optimal 650 nm.

Overall, we think the illumiflow 272 laser cap is very easy to use. All we had to do was place the laser cap on our head and press the start button. 

However, the length of each session was a bit long. In order to get results you need to use the laser helmet three times a week for 30 minutes.

Similar to other top laser caps, the illumiflow laser cap comes in a sleek black baseball cap design. This hides your bald areas and gets rid of any stress of wearing this hat outdoors.

One bad part about the design is that the lasers and the baseball are not tied together. This makes the hat feel like it is always a bit loose.

Similar to Kiierr’s laser cap, the illumiflow laser cap also has an older model with fewer laser diodes. The older model comes with 148 lasers and is less expensive.

What To Look For When Choosing A Laser Hair Cap

FDA Approval

The bare minimum for any laser hair growth device when buying is FDA approval. Without FDA approval, there is more risk of unexpected hazards from using the product.

Taking a step back, the hair that you are trying to grow back is on top of your head. And your head is one of, if not the most, important parts of your body.

So why would you want to risk the safety of your body and health?

Buying laser hair growth caps with FDA approval ensures that the product was tested rigorously and has met high quality standards.

Hair Loss Pattern

Everyone has a different situation and buying the right laser hair growth device is different for each person.

For those dealing with hair loss, you can experience balding on your crown, you have a receding hairline, or your hair may be falling from other areas.

Depending on your hair loss pattern, you will need to choose a device that can target your specific bald spots.

In general, laser caps are great for crown baldness and hair loss originating at the vertex of your scalp. Laser caps typically have the most lasers and LED lights, so you are safe buying them for many different hair loss patterns. 

Hair Loss Severity

What stage of your hair loss journey are you at? 

Unfortunately if you have been bald for many years, then a laser hair growth device won’t help you much.

This is because your hair follicles are already dormant and laser stimulation won’t help create new hair growth.

If you fall into this bucket, then we recommend that you save your money and not invest in a laser hair growth device.

Frequently Asked Questions

Do Laser Hair Caps Work?

This is a question that many people ask, especially those who are looking for a way to stimulate hair growth. There are several devices on the market that claim to be able to do this, but do they really work?

Laser hair growth devices work by emitting low-level laser light energy onto the scalp. This energy is thought to stimulate the cells in the hair follicles, which in turn can promote hair regrowth. 

While there is some evidence to suggest that these devices may be effective, more research is needed to confirm their efficacy.

If you’re considering using a laser hair cap for hair loss, it’s important to consult with a dermatologist or other healthcare provider.

Can Thinning Hair Grow Back?

Male pattern baldness is the most common type of hair loss in men. It usually starts with a receding hairline and thinning at the temples. Over time, the bald patch may get bigger and the hair on the back and sides of the head may get thinner.

Low level laser therapy (LLLT) has been shown to be an effective treatment for male pattern baldness. LLLT helps to stimulate your hair follicles, which can help to promote new hair growth and slow down or stop hair loss.

Can I Use My Laser Cap Everyday?

Yes, you can use your laser cap every day to help regrow your hair. 

Laser caps are a type of laser hair growth treatment that uses low-level lasers to stimulate the growth of new hair. 

This treatment is usually done in a series of sessions over a period of weeks or months, but some people see results after just one session. 

There is no danger in using a laser cap every day, and in fact, it may even speed up the rate at which your hair grows back.
