red light therapy for hair growth dose

Researchers tested low level light therapy to see if it would reduce scalp inflammation that interferes with hair re-growth. They tested the L’Oréal LLLT/GentleWaves® device’s effect on hair growth. 64 men with androgenetic alopecia received 590 nm for 70 seconds (pulsed) 1x/day for 3 days. Their scalps were DNA squenced. Then they tested the device as well as Minoxidil on 135 men and women with alopecia. The 590 nm treatment correlated with downregulation of sclap inflammatory biomarkers in half the treated subjects. The second study showed increase Minoxidil hair growth. Those receiving 2% Minoxidil responded as if they had received 5% Minoxidil.

Researchers tested 785 nm (infrared) light on balding patients aged 17 to 45 years old.

The treated group received 5% minoxidil solution and infrared light therapy two times per day.

The control group received 5% minoxidil and a sham LED treatment device.

Researchers tested hair patient satisfaction,  hair density and hair growth.

At 12 months, the patients getting both minoxidil and LED ligh therapy were singificantly happier with their hair growth than the sham group.

Researchers applied 660 nm LED light to balding men and women over a 24 week study.

The light therapy significantly increased the hair’s coverage area.

More of the subject’s heads had hair at 24 weeks than at the beginning of the study.

The sham group saw no hair gains.

Researchers also used 650 nm red laser light, and got the same results.

Researchers treated balding men and women aged 19 to 65 years old with 655 nm red light therapy (LLLT: low level light therapy).

They fitted helmets with 2.36 mW LED 655 nm output to administer the treatment.

They tested hair growth at 0, 8 and 16 weeks.

At the end of 16 weeks, particpants in the treatment group had more hairs and they were thicker as well.

The control group did not experience an increase in hair quanity or thickness.

There were no adverse side effects.

Hair Regrowth and Lichen Planopilaris Symptom Reduction

Researchers treated patients to low level light therapy (LLLT) using red light with a  630 nm wavelength.

All treated patients had lichen planopilaris.

Symptoms included redness (erythema), corkscrew hairs indicating too much keratin production (perifollicular hyperkeratosis), and hair loss.

After 3 and 6 months, the patients had more and thicker hair.

After 3 months, the erythema and perifollicular hyperkeratosis settled down, but after 6 months it had returned.
