It’s been long known (and clinically proven) that Low-Level Laser hair growth devices are highly effective in regrowing hair and reducing hair loss – 100% naturally.

If you want to save a ton of money (and time) on dermatologist or hair clinic treatments – laser helmets and laser combs are your two best options.


Which one is more effective for hair growth?

What’s the difference between laser caps and laser combs?

Which one is best for YOU?

In this post you’ll find all the answers:

We’ve compared all aspects of laser combs and helmets with their pros and cons:

The technology, the treatment time (the effort factor), the ease of use, the price and of course – the results.

Laser Helmets vs. Laser Combs: Full Comparison

First, here’s what you need to know:

  1. Both types of LLLT hair devices are based on the same proven technology.
  2. Science has shown that Low-Level Laser (LLLT) is safe and effective for stimulating hair follicles and regrowing new, full and healthy hair – for both men and women (with Androgenetic Alopecia and other conditions).
  3. The laser wavelength used in both laser caps and laser combs is around 650 nanometers (visible red light).
  4. Improvement (reduced hair fall and noticeable hair growth) was reported after 12 to 26 weeks of continuous use – for BOTH laser caps and laser combs.

(See this post for a full explanation of how red light therapy works for hair loss.)

So, the basics are the same. What are the differences then?

In this comparison, we’ll look at the best (through our research) laser combs (HairMax), vs. the best laser helmets (iGrow/iRestore).

iRestore VS HairMax

Here’s a summary in a comparison table, but we strongly suggest that you read the full details below:

1. Design & Effort Factor

Laser combs are designed to part your hair when you use them. This allows the laser light to have direct contact with the scalp.hairmax laser comb design

You start with the front of the hairline and wait a few seconds until the light is absorbed before you continue further down the back of your head.

Doubling back over the same area will not be effective, and may encourage hair loss instead of stimulating hair growth.

Laser helmets are designed to “sit” on your head, covering most of your scalp. No effort or action is required.irestore laser hair growth helmet

Professional Laser combs (such as the popular HairMax) include 7-12 medical-grade lasers (not LEDs).

Hair growth helmets combine both tiny laser diodes and red LED bulbs.

LED vs. Laser – what’s better?

Low-Level Laser can be emitted via both laser diodes and LEDs. Studies have found that LEDs and laser diodes are both effective.

So, what’s better for your hair?

Well, if you suffer from generally thinning hair in different areas on your scalp, and your scalp is not “blocked” by a lot of thick hair – the effortless helmet is a better choice for you.

On the other hand, if you want to treat bald spots and specific areas of thinning hair – use the comb to better expose those areas to the hair growth light.

2. Treatment Time

Laser brushes require 8-15 minutes of active (slow combing) treatment time (depending on the device) – repeated 3 times a week.

For example, The HairMax Ultima 9 should be used for 10-12 minutes, while the more expensive HairMax Ultima 12 requires only 8 minutes of treatment.

Laser caps/helmets usually require 25 minutes of passive treatment, every other day, on non-consecutive days.

So, the question you need to ask yourself is:

What’s more important for you: less treatment time or less effort?

If you do not have the patience to slowly comb your hair for 8-15 minutes 3 times a week, a helmet or cap is a better choice for you.

The hands-free design prevents hand and arm fatigue from having to slowly work a comb through your scalp.

If you’re really busy and not sure you’ll be consistent with treatment (which is critical), consider the new HairMax Laser Band.

Because this new device (with 82 medical-grade lasers (No LEDs). requires only 90-seconds treatment. However, it will not cover all your hair in one treatment and is very expensive.

3. Treatment Area Coverage

As seen in the images, laser helmets are hands-free and cover almost your entire scalp (less coverage on the bottom).

Laser combs cover the area you choose to comb.

4. Time to Visible Results

Both the HairMax brushes and the helmets were clinically tested and were proven to work after 3 months to 6 months of treatment.

5. Money Back Guarantee & Warranty

Since we’re talking about relatively expensive devices, you’d want to know if you can get your money back in case this technology doesn’t work for you, right?

Here’s how it works:

  1. The HairMax combs come with a 90-day money back guarantee, and a 2-year warranty (for the battery as well).
  2. The iRestore hair growth helmet and the iGrow come with a one-year warranty and full 6-months money back guarantee.

In 90 days you’ll be able to determine if you see new, healthy hair or reduced hair loss – so both options are just as good.

6. Price

Laser caps are generally more expensive than laser combs. However, sometimes we find great deals for both devices on Amazon.

Here’s an updated Amazon price table for today:

Bottom Line

In this post, we’ve compared laser hair caps with laser combs. The devices compared were both clinically proven to work within 3-6 months, and both types use the same red light wavelength – 650 nm.

We’ve determined that there is no one answer that fits all.

The chance of reducing hair loss and regrowing new, healthy hair depends mostly on how consistent you are with the treatment.

The conclusion is:

If you think you won’t have the patience to comb your hair slowly for 8-15 minutes three times a week – go for the laser helmet, which is passive, effortless and allows you to read, watch TV or just rest while you use it.

See the top 3 laser caps (+reviews) – HERE.

If your hair is generally thick and you mostly suffer from bald spots – we recommend the laser comb to part your hair to allow the light to reach the spots effectively.

Without hair parting teeth, thick hair can block a majority of the laser light energy from reaching the follicles.

However, this is only if you stick with treatment. With the red light brushes,  arms can get tired, people begin to slack and skip sessions

If you have generally thinning hair – go for the laser helmet, which offers better coverage and will stimulate blood flow in most of your scalp.

If your main concern is the price – laser combs are less costly. They also make a great first try to see if LLLT for hair loss works for you.

If it does – it may be worth it to invest in a laser cap.
