Learn Thoroughly: Can Red Light Therapy Reverse Grey Hair?

It makes you wonder, doesn’t it? Your hair problems might be resolved with red light therapy. In the end, red light therapy could potentially be a viable option for the reversal of grey hair.

Even though reverse hair greying is not a quick process, you receive what you put into most things in life. But when applied appropriately and consistently, it can have a long-lasting and beneficial effect on your hair and scalp. And whether it reverses grey hairs or makes your hair grow faster, there are plenty of other health benefits to keep in mind as well.

Recent studies have found that red light therapy can prevent the aging process and make us look younger. Therefore, it should come as no surprise that red light therapy is growing in popularity among those who want to slow down the greying process and maintain the health of those natural pigments.

By encouraging the body to manufacture more melanin, red light treatment can aid in reversing this process and halting further hair graying. The red light aids in promoting blood flow and oxygen delivery to the hair follicle roots. This is crucial because it makes it possible for your body to naturally manufacture more melanin by improving the flow of nutrients and oxygen to your scalp.

The red light penetrates the cells deeply and activates certain enzymes that hasten cellular repair, reduce inflammation, and mend damaged cells. This provides the nutrition your hair follicles need to regenerate healthy strands of hair.

Through these processes, red light therapy can stop additional harm and encourage healthy hair growth in its place. Additionally, red light treatment is fantastic for minimizing dandruff and enhancing scalp health. So, it is the best way to reverse grey hair.

However, there are a few small studies that have shown promising results, but more research is needed to confirm its efficacy. Through research, patients with less than 50% grey hair had successful treatments in 79.1% of the instances (95% confidence interval: 68.8% to 86.6%) when successful hair removal was defined as more than 25% of the hair removed after 90 days. The success rate for patients with more than 50% gray hair was 66.9% (range: 51.3% to 79.5%).

So, if you’re interested in trying red light therapy to reverse grey hair, be sure to consult with a doctor or dermatologist first to see if it’s right for you. You’ll understand why when you give it a try yourself. Many celebrities even utilize this treatment on their scalps as part of their beauty routine.

The Reason Behind the Grey Hair Reversal

Simple genetics, aging, and exposure to harmful substances like the sun are just a few of the many factors that contribute to greying hair. One most people aren’t aware of is oxidative stress, where the problem comes from damage to the amino acids that are natural pigments in our bodies.

As this stress builds up over time, it discolors our hair. This can start to show as early as our 30s, but when we hit our 50s, the hair becomes even more susceptible to damage. This type of damage causes a reduction in melanin production and therefore causes grey hairs to appear. We will go over a few of the factors here:

Cause of Age: The main cause of graying hair is aging. As was previously said, as we get older, our hair follicles are less able to produce the same amounts of melanin pigments. Although grey hair typically appears on people in their midlife, some people can start noticing it as early as age 20. In a similar vein, some people never get gray hair.

Stress & Anxiety: Since our lifestyles are continuously changing, worry and general stress can also contribute to grey hair. Our hormone synthesis, hair follicle function, and organ functions are all altered by stress and anxiety-related events. The state of your hair can be affected by stressful situations such as traumatic experiences or pregnancy in women.

Genetics: People with grey hair are significantly influenced by genetics. It’s likely that you will experience grey hair at a similar age as your parents or grandparents.

Disorder: Disorders like autoimmune disorders can be significant contributors to the onset of gray hair. The most common autoimmune condition that can damage your hair is alopecia. Due to a lack of melanin, hair often regrows as a grey or white colored strand in situations of alopecia and hair loss.

Diseases: Grey hair can be a symptom of diseases like vitiligo. In the disorder known as vitiligo, the cells responsible for creating pigment are destroyed. Skin tissues and the hair that surrounds them begin to turn white as a result.

How Can You Reverse Grey Hair with RLT? How Does It Work?

The hair follicles can be strengthened and made thicker with the application of red light therapy for grey hair. Laser treatment, which can be applied with devices called laser caps, is another name for red light therapy. This treatment is a fantastic choice to consider if your hair is beginning to turn grey and feels thin and fragile.

Laser diodes in laser caps provide red light therapy to enter the scalp tissue and promote fresh, healthy growth in the hair follicles. Additionally, this treatment can assist in reducing scalp inflammation, which creates a healthy environment for the development and growth of hair follicles.

Laser caps are a hands-free, non-invasive hair growth treatment option that has received FDA clearance. Start your reverse grey hair treatment journey right away to get those strands healthy and strong. Do not wait until your hair starts to thin even more.

Devices for Red Light Therapy for Heirs at Home

Numerous new devices have recently entered the market as a result of the procedure’s rising popularity. Your task is to find the tool that will accomplish your goals with the least amount of work. The following gadgets are the most appropriate for use at home. Reminder: Only invest in appliances that have received FDA approval.

  • Heir cap: Consider for a second that you are putting on a helmet before boarding a motorcycle. This strategy is similar. Small probes on the gadget deliver the red/infrared LLLT. To completely or partially enclose the scalp, hair caps are available. Recommended when the treatment area is larger. At wavelengths between 650 and 900 nm, frequency controls for wavelengths are available.
  • Hair straighteners: Like a typical hair straightener, they operate. The regeneration of dry hair split ends, and damaged hair is its finest application. This tool does more than just aid in hair repair. Additionally, it aids in preserving healthy hair while straightening. By closing the cuticles and retaining the moisture in the hair follicles, all of this is made possible.
  • LED Laser: Treatments with LED laser light are most effective on very specific scalp regions. These gadgets are simple to use and emit laser light at frequencies that are suitable for treating hair. These tools are adaptable enough to be used with other RLT techniques. They cannot, however, be used on the eyes.
  • Hair dryer: These tools perform the same tasks as a typical handheld hair dryer or blower. The red or infrared light treatment is best for maintaining healthy hair since it encourages hair development and repairs damaged hair.
  • With low EMF: Watch out for any electromagnetic frequencies (EMF) that your red light therapy equipment emits. If exposed to a high quantity of EMF over an extended period of time, it may be dangerous.
