Light therapy for hair growth: what the science says

Low-level light therapy (LLLT) has been evaluated primarily for treating pattern hair loss in male and female patients, which is the most common form of hair loss. Many clinical studies have shown LLLT to be safe and effective in improving hair density (number of hairs per scalp area) and hair caliber (thickness of the individual hair). Therefore, LLLT is currently considered a useful non-surgical and non-pharmacologic method of supporting hair loss.

Currently, the optimal light to stimulate hair growth is thought to be red light within the wavelength of 650 nm, noting beneficial results. When comparing laser versus LED light, some findings suggest that laser light is more effective than LED. However, using a combination of laser and LED lighting is effective and can reduce the overall costs of the hair growth device.

Tips for maximizing results with a laser hair growth cap

To maximize the results of a laser hair growth cap, here are some tips to follow:

  • Select a high-quality laser hair growth cap. Ensure that it produces low-level laser light therapy within the recommended wavelength.
  • Consistency. For best results, it is important to follow the recommended frequency and length of treatment sessions. Devoting specific times in your day to accomplish this will help to improve your consistency and results.
  • Talk with your doctor or dermatologist. They may recommend using additional pharmacologic products, such as minoxidil, an FDA-approved product for hair loss. Minoxidil has been shown to improve results when combined with a laser hair growth cap.
  • Shampoos, conditioners, and multivitamins. These products can help to fortify and strengthen hair, which may improve your results. Many laser light companies have these products for purchase; however, verify with your doctor that they are safe before starting any new supplement.

Common misconceptions about laser hair growth devices

The use of laser hair therapy has been cleared by the FDA and is deemed safe and effective in managing male and female pattern baldness. However, many myths regarding this relatively new technology continue to be propagated across the internet. Therefore, let us clear up some of the most common myths.

Many advocate that lasers can bring dead follicles back to life; however, this is not true. Laser light therapy stimulates dormant hair follicles to activate and produce healthy hair growth. On the other hand, once the follicle has died, there is no rejuvenating it to resume hair production.

While many wish for immediate results, it takes time to activate the dormant hair follicles and produce visible results. One misconception is laser light only affects the skin's surface. However, most devices use medical-grade diodes to produce high-powered lasers that penetrate into the hair follicle.

Other ways to improve hair growth

Hair loss affects many male and female patients, resulting in numerous products geared at improving or halting hair loss. In addition to laser hair growth caps, other options include:

  • Red-light devices. Caps or helmets are not the only way to utilize low-level laser light therapy. Combs and headbands are available as options and are often available at a cheaper price point.
  • Dietary supplements. Specific vitamins, such as biotin and niacin, may improve hair health, but currently, no concrete scientific evidence is available to back the use of these supplements.
  • Serums and shampoos. Numerous topical agents applied directly to the hair are available that may improve hair growth, but research dedicating to their effectiveness is lacking.
  • Pharmacologic agents. Two agents, minoxidil and finasteride, are FDA-approved and have been shown to be effective in treating hair loss. However, finasteride is only used in men.

Concluding recommendations for the best laser hair growth device

Hair loss can affect one's self-confidence and cause significant distress. Fortunately, there is no shortage of options to help slow hair loss and encourage growth. One of these methods is using a low-level laser light therapy device. These devices are FDA-cleared and are safe and effective for supporting hair growth.
