Hair loss is a common concern for so many people. The good news is that there are various solutions available that may help restore your hair.

One solution that’s attracted a lot of popularity recently is red light therapy for hair loss. But does it really work?

Keep reading to learn whether red light therapy devices can help with hair loss.

Does red light therapy help with hair loss?

Yes, red light therapy (RLT) has indeed shown promise in helping with hair loss. A laser hair growth device works by using low-level lasers or LED lights to penetrate the skin and stimulate hair follicles.

The theory is that red light, at specific wavelengths (usually in the range of 650 to 1200 nanometers), can increase blood flow around the scalp. This improved circulation may help deliver essential nutrients and oxygen to hair follicles, which creates a healthier environment for growth. Also, red light may boost cellular metabolism within the follicles, which may potentially lead to thicker and healthier hair strands.

A study from 2013 of 41 males aged between 18 and 48 found that laser hair treatment can promote hair growth. It led to a 39 percent increase in hair growth after using the device for a period of 16 weeks.

Another study in 2018 supported the use of red light therapy for hair growth, especially in people with androgenetic alopecia. This study showed that RLT treatments led to a significant increase in hair count and diameter.

Is it safe to use RLT for hair loss?

Yes, a laser hair growth device is generally considered safe to use for hair loss treatment. RLT is non-invasive, which means it doesn’t break the skin or require any recovery time. The light used in these devices usually uses a lower power level than most lasers, which reduces the risk of burns or skin damage.

However, as with any treatment, it’s always important to consult with a dermatologist before you start, especially if you have any underlying scalp conditions.

Types of red light therapy devices for hair loss

Red-light therapy devices are gadgets made to conduct red-light therapy, offering the convenience of red light therapy at home or for professional use. There are so many types of laser hair growth devices for hair loss available today. Some of them include.

Laser hair caps. Laser cap devices are often baseball caps. They have a rechargeable battery that powers the rows of LEDs lining in the interior of the laser cap. These devices work particularly well for individuals who want hands-free hair loss treatments. 

Helmets. Like laser hair caps, these devices fit over your head and deliver low-level laser therapy to the scalp via rows of laser diodes.

Combs or brushes. These are handheld devices that allow you to target specific areas of your scalp. The lasers are embedded within the brush or comb. They may require more effort and time, as you have to manually move the device across your scalp.

Hood-style devices. These are found in clinics and salons. They look a lot like the hood dryers used in hair salons.

How to choose the device for your needs?

When shopping for red light therapy devices, there are a few factors to consider. 

• Wavelength. Wavelength is important when it comes to choosing a laser hair growth device. The wavelength determines the strength of light as well as how effective it will be on your scalp. Typically, between 650 and 655 nanometers.
• Comfort. Of course, comfort is always key. A device that causes discomfort may limit your consistency. So, look for a device that is comfortable and easy to use.
• FDA approved. Look for an FDA-cleared device. This shows that the device passed the tests to meet standards for both safety and efficacy. 
• Affordability. While a red-light device is a one-time investment, they can be expensive. That’s why it’s important to choose a device with affordable prices.

How to use red light therapy devices for hair loss

Using a red light therapy device is pretty straightforward. Here are some simple steps to follow.

1. 1. Start with a clean scalp. Make sure your hair and scalp are clean before the treatment.
   2. Follow the manufacturer’s instructions carefully. Each and every device comes with specific guidelines for safe use.
   3. Position the device according to the instructions. Turn on the device and wear it for the recommended duration of time, usually 10 to 20 minutes.
   4. Use the device consistently, typically 2 to 3 times per week, for the best results.

Remember it’s important to manage your expectations. Some studies show promising results. But it might take weeks or even months of consistent use to see noticeable improvements. It can take up to 3 to 6 months before you see any noticeable results.

Are there any side effects?

There aren’t a ton of downsides for using red light devices for hair loss. Most patients report no issues or just mild side effects such as scalp redness or irritation if you use the device too often. If you experience any discomfort, stop using the device and consult with your doctor.

Who should avoid using RLT?

As mentioned earlier, these devices are generally safe to use. But they may not be suitable for everyone. Pregnant and breastfeeding women should avoid using red light devices for hair loss. Additionally, if you’re taking medications that increase sun sensitivity, consult a doctor before using these devices.

Should you get a red light therapy device for hair loss?

So, should you use red light therapy for hair loss? Red light therapy shows promise as an effective method of hair loss treatment. If you’re experiencing thinning hair and are looking for a safe and invasive option, these devices might be worth considering.

However, it’s important to consult with a dermatologist to determine the underlying cause of your hair loss and to discuss the best treatment options for you.
