LED red light Therapy not only provides benefits in slowing or reversing the gray hair but also comes with some limitations. RLT is a non-invasive, chemical-free treatment that shows promising results in keeping scalp and hair healthy.
Unfortunately, red light therapy is not proven to reverse gray hair. Gray hair occurs due to a decrease in melanin production in the hair follicles. Although red light therapy increases blood flow to the hair follicles and promotes healthy hair growth, it does not affect melanin production.
It's not possible to reverse or treat gray hair. But, with advancing research, this may be an option in the future.
3. Red light therapy changes your hair colour. Red light therapy does not contain any particles which can interact with the pigment in your hair.
Johnson attributed his transformation to a multi-faceted regimen that includes nutritional support, topical applications, and light therapy. He emphasized the importance of taking proactive measures early to maintain a full head of hair.
However, reversing your grey hair is much less likely if you're older. To reverse grey hair, you need enough melanocyte stem cells (McSCs), which produce pigment cells (melanocytes) for your hair. These stem cells stop working with age, and hair greying is thought to be irreversible when they do [3].
Used over multiple months consistently, red light has been shown to regrow thinning hair. But it should also be noted, when the person stops applying red light, the effects stop." The dilation of blood vessels enables more blood and nutrients to reach the hair follicles.
It is important to note that more frequent usage doesn't necessarily mean better results; overdoing it could lead to irritation and sensitivity in the treated areas, so it's best not to exceed the recommended frequencies.
In most cases hair regrowth has been seen after 12 to 26 weeks using red light therapy, including loss of less hair each day and a noticeable improvement for hairs growing on the head. With the addition of certain hair serums, results can be obtained in only a few weeks, especially if paired with red light therapy.
Vitamin A foods
So, when looking for ways to improve melanin production in the body, including Vitamin A-rich foods is an absolute must. With enhanced cell differentiation, Vitamin A also promotes the production of melanocytes, which, in turn, triggers melanin production.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12.
That said, certain conditions may temporarily restore pigmentation. For example, if greying is caused by a vitamin deficiency, stress, or an underlying medical condition, addressing these issues may slow or even partially reverse greying. However, the complete reversal of naturally aged hair remains a challenge.
Premature graying may be reversed with vitamin B12 supplementation only if vitamin B12 deficiency is the cause. If you are graying due to other factors, such as genetics, zinc deficiency, and medications, your gray hair cannot be reversed.
Additionally, 633 nm (96 J/cm2) red light LED was reported to decrease melanin levels significantly after phototherapy of patients with acne vulgaris [62]. Similarly, 660 nm red light showed a depigmenting effect with downregulation of tyrosinase and MITF, due to increased ERK activity [63].
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
Using red light therapy for hair growth is all about balance—neither too much nor too little. The safe red light therapy duration for hair growth typically involves 2-4 sessions per week, with each session lasting 10-20 minutes. Consistency is your best friend here, as skipping or overdoing it can delay results.
The recommended frequency of use for red light therapy will vary depending on the condition being treated, but most people will see benefits with 2-3 sessions per week. However, it is important to note that seeing a healthcare professional before starting any treatment with red light therapy is recommended.
For some people, a daily session of 10-20 minutes is sufficient to achieve the desired benefits, but this may vary depending on the condition being treated and the intensity of the light. It is also important to protect the eyes and skin from exposure to light, as prolonged or intense exposure may cause harm.
It uses red light at 633 nanometers and infrared light at 830 nanometers to stimulate cell renewal for firmer and tighter skin.” The anti-aging device has been clinically proven to reduce the appearance of wrinkles in just four weeks.
Safe, science-backed, and gentle on the skin, red light therapy helps reduce puffiness and dark shadows under your eyes by stimulating collagen and easing inflammation.
Results vary from person to person, making it hard to definitively say how long it will take to lose weight from red light therapy, if you lose it at all. However, research has found that people have lost weight from these treatments in as little as two weeks when they do several sessions a week.
The LED Hair Growth Helmet is powered by a spectrum of red light (620-660nm). These clinically proven wavelengths energise hair follicles, reduce inflammation, lower dihydrotestosterone (DHT) levels (a hormone known to cause hair thinning and loss) and improve scalp blood flow.
