Studies suggest that red light therapy can increase hair growth by 35% to 51% compared with placebo when used over 16 weeks [1-3].
Conclusion: Both red and green LED therapies effectively enhanced hair growth, increasing density and thickness over 6 months.
Red light reduces inflammation and increases energy in our skin and hair cells. Blue light, on the other hand, is said to induce low-level hair growth through a different mechanism. In a recent study, blue light increased hair density and shaft diameter by 90% after ten weeks of use.
Several light therapy devices for hair growth have hit the market this year. Skin-tech leader Currentbody has launched a slightly frightening-looking but thoroughly thought-out LED helmet, which has been clinically proven to accelerate hair growth and improve the appearance of thickness.
The best technologies to regrow hair at home include red light therapy, low-level laser therapy (also referred to as cold laser therapy), and microneedling, says Dr. Ziering.
In general, blue light spectrums encourage vegetative and structural growth and red light promotes flowering, fruit, leaf growth, and stem elongation.
Blue Light is an excellent help to those who suffer from inflammatory scalp conditions and who may be afraid of harsher treatments and medications. Used in conjunction with targeted scalp treatment Blue light therapy is an effective treatment for healing the scalp which can lead to hair loss.
Previous studies have indicated that 650-nm red light is the most effective and practical way for stimulating hair growth via LLLT treatment.
LEDs cannot be tuned into specific wavelengths because they produce multiple at the same time. This makes it almost impossible for them to reach the hair follicle. Due to these disadvantages, LEDs aren't as effective as lasers when it comes to reaching and stimulating hair follicles.
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.
Ziering also says there is evidence to suggest that too much blue light exposure can accelerate genetic hair loss in both men and women. UK-based trichologist Kate Holden, on the other hand, suggests that some blue light exposure to hair is harmless, and it's more about the time of day that you're exposed to it.
How does an LED hair growth helmet work? “It works by boosting cellular regeneration and stimulating follicle strength to improve overall scalp health,” says Dr. Engelman. “It can also prolong the anagen (growth) phase of the hair cycle, encouraging thicker, fuller hair,” she adds.
Blue: This is the most important light for plant growth. It is easy for chlorophyll to absorb and convert into energy. Red: As the second most important wavelength, red light is incredibly potent for plants when combined with blue light. Orange: Similar to red light, but less effective.

Natural White. If you prefer a balanced ambiance that's not too warm or too stark, natural white is the way to go. With a color temperature of 4000K, this neutral tone is ideal for general office lighting.
The precision red 633nm and near-infrared 830nm LED wavelengths used in our salons and devices increase the blood flow in your scalp. This stimulates your hair follicles and improves their metabolism, encouraging re-growth and minimising hair loss.
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.
Studies suggest that red light therapy can increase hair growth by 35% to 51% compared with placebo when used over 16 weeks [1-3]. LLLT has been around for decades as a treatment for wound and tissue repair, as well as pain relief.
Blue Light Treatments for Severe Acne
The purpose of using blue LED light is to control bacteria. So, to treat severe acne, you can use your Clinical device several times a day, as long as there is no irritation resulting in redness or rashes.
Green light has calming properties that can help reduce inflammation. It also helps address hyperpigmentation to reveal an even and brighter skin tone. Green LED light therapy is used for treating circles under the eye, sun spots, and dilated skin capillaries.
Eat protein-rich foods
Protein is important because each strand of your hair is made of keratin, a tough protein that's also used to create fingernails and skin. If you don't consume enough protein, your body will divert its protein sources to more critical areas, and your hair may suffer.
Effective treatments for promoting growth include FDA-approved options like minoxidil and finasteride, as well as home remedies like biotin supplements, scalp massage, microneedling, natural oils, and gentle hair care routines.
Typically, hair grows an average of about half an inch each month. 1 This means hair grows about 1/8 of an inch each week, and you can expect your hair to grow one-and-a-half inches in three months.
