As we age, many of us start to see those inevitable signs of getting older – wrinkles, age spots, and yes, graying and white hair. While some embrace their natural silver locks, others long for the return of their original hair color. If you’re in the latter camp, you may be wondering -can red light therapy reverse gray/white hair and restore your natural shade?
Red light has been shown to help reactivate dormant hair follicles, which can lead to some darkening of white hairs. Let’s take a closer look at how red light therapy affects white hair, its effectiveness, and safety, and how to use it properly to get the best results.
What Causes Our Hair To Turn White?
Graying and white hair is caused by a loss of melanin, the pigment that gives hair its natural color. Melanin is produced by pigment cells called melanocytes that live in the hair follicles. As we get older, melanocytes become less active, produce less melanin, and eventually stop producing pigment altogether. This causes new hair strands to grow lighter and eventually completely white.
Genes play a major role in when and how quickly we go gray. However other factors like stress, smoking, vitamin deficiencies, and autoimmune disorders can accelerate the graying process.
Once a hair follicle stops producing melanin, that strand of hair is devoid of pigment forever. The only way to restore color is to reactivate the dormant melanocytes so they start producing melanin again. This is where red light therapy comes in.
When It Comes To Reversing Graying
Red light therapy can have different effects depending on what stage your white hairs are at:
- Partially Gray Hair: If your hair is salt-and-pepper or still has some pigment left, red light can help slow down and minimize further graying. Photobiomodulation helps stimulate melanocyte activity, allowing the melanocytes to continue producing some melanin to color those hairs.
- Fully White Hair: Hairs that are completely devoid of melanin are harder to restore to their original color. However, red light therapy has been shown to reactivate some dormant melanocytes, leading to partial darkening of white hairs. However, the effects are limited – the true reversal of bright white hairs is difficult to achieve.
- White Regrowth at Roots: Red light can stimulate melanocyte activity where the hair meets the follicle. This can lead to new growth coming in darker at the roots, minimizing the contrast between white lengths and darker regrowth.
The takeaway is that red light works best for minimizing and slowing down the graying of hair that still has some natural pigment left. It can help “stave off whiteness” and prolong your natural color. Reactivation of fully white hairs is possible but limited.
How Red Light Therapy May Impact Gray Hair?
Here are three ways red light is proposed to boost melanocyte activity and melanin production:
- Improves mitochondrial function: By improving mitochondrial function and energy supply, red light therapy may enable melanocytes to ramp up melanin synthesis again.
- Reduces oxidative stress: Red light therapy enhances antioxidant defenses to help clear out these damaging free radicals. Lowering oxidative stress protects melanocytes and creates a better cellular environment for melanin synthesis.
- Stimulates cell signaling: Red light is absorbed by specific receptors in cells, initiating signaling cascades that ultimately turn on genes involved in proliferation, migration, and melanin production.
Through these proposed mechanisms of improved mitochondrial function, reduced oxidative stress, and cellular activation, red light therapy may revive melanin synthesis in graying hair.
What Does the Research Say About Red Light Therapy for Gray Hair?
Research shows that red light therapy has the highest chance of success with early graying when melanocytes are still present. It likely won’t reverse extensive graying or completely white hair since the melanin-producing cells are gone. Individual results will vary based on the rate of melanocyte decline, genetics, and health factors.
So in summary, early clinical evidence and mechanistic studies provide some proof-of-concept that red light therapy may help treat gray hair in the early stages. However larger-scale human trials are needed to definitively determine efficacy and optimal protocols.
Red Light Therapy Procedures for Gray Hair
If you decide to try red light therapy for gray hair, here are some tips for optimal procedures and devices based on the current research:
- Wavelength: Stick to red wavelengths between 630-660nm. These deeper penetrating wavelengths are thought to work best for affecting hair follicles.
- Light source: Look for light-emitting diode (LED) devices designed for red light therapy rather than lasers. LEDs distribute light evenly for better coverage.
- Frequency: Most studies applied red light 5-7 days per week for maximum stimulation. Using it only occasionally may not produce results.
- Fluence: Optimal fluence (dose) is likely in the range of 10-40 J/cm2. Going above this doesn’t seem to boost effects.
- Time per session: To reach optimal fluence, you’ll need 10-20 minute sessions depending on your device output.
- Duration: Consistency seems to be key. Stick with an LED regimen for at least 3 months to cover the entire hair growth cycle.
- Hair parting: Part your hair to expose your scalp and get light down to the follicles. You can spot-treat thinner areas.
- Head movement: Slowly moving your head side to side helps spread light over every area of your scalp for best coverage.
Be sure to follow instructions for your specific device and adjust settings as needed. Be consistent, use it in the 10-40 J/cm2 fluence range, and give it at least 3 months before assessing results.
Are There Any Side Effects of Red Light Therapy for Hair?
Red light therapy is considered very safe with minimal risk of side effects. Here’s what you need to know:
- It’s painless and non-invasive using gentle LED light. No harsh chemicals or damage to hair like dyeing.
- FDA-cleared red light devices have been tested for safety and effectiveness. Look for 510(k) clearance.
- Use eye protection if needed. Avoid directly shining light into the eyes.
- Follow precautions if you’re photosensitive or on medication that increases sensitivity.
Overall red light therapy is very low risk especially if you follow product instructions.
Tips for Using Red Light Therapy to Treat Gray Hair
If you want to give red light therapy a try for covering grays, consider the following usage tips:
- Invest in a quality device: designed specifically for red light therapy. The RedDot LED device is a top option we’ll discuss more shortly.
- Use it consistently: 5-7 days per week is ideal for continuous stimulation.
- Session duration: should be in the 10-20 minute range depending on your device output and hair density. Thicker hair may need longer treatment times.
- Start by parting your hair: to ensure the light reaches your scalp. You can spot treat especially gray areas.
- Slowly move your head: during sessions to distribute light evenly across your entire scalp.
- Take a targeted approach: – focus the light directly on graying areas of your hairline, temples, part line, crown, etc.
- Be patient: – it can take at least 3 months to move hairs through a full cycle to see results. Give it 6 months for a better assessment.
- Consider using it before bed: so you don’t have to fit it into your morning routine.
- Use in combination with melanin-stimulating products: like copper peptides, ginseng, Fo-Ti, black tea extracts, etc to maximize results.
Regular use is the key. So try to make red light therapy part of your daily or every-other-day hair care regimen.
