The benefits of red and infrared light:

Red light therapy: This form of phototherapy harnesses the positive effects of red light, including the stimulation of hair follicles and the increase in the number of hairs.
Infrared light: In addition to red light, infrared light contributes to scalp health by stimulating collagen production and reducing oxidative stress.
LED Light Therapy: LED therapy combines different light spectrums, including red and infrared, to promote hair and scalp health.

Backed by science
Studies conducted by renowned research institutes, such as Harvard Medical School, have demonstrated the effectiveness of red light phototherapy in the treatment of hair loss. This form of phototherapy not only offers hope to people with hair problems but also improves the overall condition of the scalp. PubMed has several online studies on the effect of red light therapy on the scalp.

Studies on Baldness in Men
In 2019, researchers conducted a 6-month study on men with patterns of hair loss and changes in protein expression in their dermal papilla cells, which are responsible for hair growth. Participants received 25 minutes of red light therapy on alternate days for 6 months. By examining which proteins were upregulated, the researchers concluded that red light therapy promoted hair growth and reversed the miniaturization process of hair loss by improving the function of dermal papilla cells.

In 2014, another study was conducted to determine the safety and physiological effects of red light phototherapy in men with baldness. 44 men participated, and part of the scalp was trimmed to a height of 3 mm. The area was tattooed and photographed. One group received red light treatment on alternate days for 16 weeks, while the second group received a simulated treatment. At the end of the study, the researchers observed the following:

A significant increase in the number of hairs after treatment in the group treated with red light. A 35% increase in hair growth in the group treated with red light. No side effects or adverse effects were reported.
