Using the correct wavelength is essential when using light for laser hair treatment. Studies have found a range of 650-670 nm to have the most efficient and effective absorption, making it the most effective wavelength for hair loss therapy.

Several studies have been conducted over the past five years which have demonstrated that Low Level Laser Therapy is effective in the treatment of hair loss for both women and men.

Low Level Laser Therapy and hair loss products like Rogaine and Propecia can be used together, though this is not a requirement. In fact, LaserCap, Capillus, or iGrow are excellent alternatives to these products as it is just a one-time investment that does not require monthly prescriptions or doctor visits. Furthermore, it isn’t messy or difficult to apply and has no side effects.

Not all devices are created the same. Different devices use different power and energy outputs and, as such, they will not provide the same results. Some devices cover only small areas of the scalp. Some do not produce enough energy to stimulate hair rejuvenation. Still others, like many handheld Low Level Laser Light Therapy devices use only LED light or have just a few lasers. The majority of Low Level Laser Light Therapy devices have insufficient power. Worse, the user often has to manually move a comb or brush over the scalp repeatedly for ten to twenty minute periods. These products are not only a hassle; they are often ineffective and unable to provide excellent results. The LaserCap, Capillus and iGrow have addressed these problems by creating hands-free, easy to use, automated devices large volumes of true laser diodes for complete, consistent scalp coverage during each 20-30 minute session from the comfort of your home.

Yes, Low Laser Light Therapy products like LaserCap, Capillus and iGrow are routinely endorsed and used by dermatologists and medical doctors throughout the U.S., Europe and Asia for hair rejuvenation in patients with hair loss.

Just because something is “the original” doesn’t make it the best. Newer, more advanced technology comes along every day – a great example of this would be smart phones or computers. In the case of laser light therapy, it isn’t that the technology is outdated (this particular wavelength of light has been used to treat hair loss for over 10 years now), but rather that the application of the technology has advanced much further.

The 3 best devices that we’ve found, Lasercap, Capillus, and the iGrow, all provide full scalp coverage with no need to brush or comb the hair at all. With units like these that cover the entire scalp, the worry that parts of the head will be missed or skipped over while using a laser comb or wand is eliminated, not to mention that more true lasers can be implemented in the larger units, rather than the typical 10-15 that came with the smaller, outdated combs. When you consider that you will spend $4-500 on a comb or wand that only covers a very small area (and as a result may end up not working for many patients), it only makes sense to spend a little more for something much, much better.

Researchers in the late 1960s effectively used low-level light therapies for wound healing. Hair restoration in the treated areas was a side effect of this application.

None at all. The LaserCap comes in 2 different sizes – regular and large. The regular size cap fits up to a 7 ½ hat size, or around 85-90% of our patients, and the large cap fits patients with a hat size of 7 ½ and above. The actual unit has a degree of flexibility to it so that it can fit all different shapes and sizes, and it’s very lightweight so that it’s comfortable to use.

The wavelength used for combatting hair loss is often referred to as a “cold” laser – it’s a much different wavelength than things like laser hair removal (obviously the total opposite of what you are trying to accomplish). It doesn’t really get hot, although the LaserCap can occasionally get a little warm, which is to be expected when you have 224 lights all in one place.

We have patients from California to New York and back again, and one of the main questions people have is can they wear a LaserCap, Capillus, or iGrow, while outdoors, and the answer is yes. It’s totally safe to wear your device in just about any weather. Remember, however, it only needs to be worn for about 30 minutes, 2-3 times a week, so you will have plenty of opportunities to wear it on the go no matter where you live!

Unfortunately the only thing that actually replaces lost hair is an actual hair transplant, so comparing laser light therapy to hair transplantation surgery is like comparing apples and oranges. Laser light therapy is there to help patients hold on to the rest of their original hair with an 80% success rate and zero side effects, and a transplant gives patients the opportunity to replace the hair they’ve lost.

Laser light therapy is completely safe to use after a hair transplant. Laser light therapy increases the blood flow to the scalp, which is actually one of the reasons that we encourage patients to use it immediately following a hair transplant. While it can give transplanted hair a boost and help transplants to possibly grow in a little faster, the main focus is to stop the hair loss from progressing, helping patients to hold on to the rest of their original hair while filling in the problem areas with the hair transplants.
