About the Brand

The manufacturer of the Aseir Red Light Brush is Aseir Custom, founded in 2019 by world-renowned optimization health experts and biochemical engineers Nick Andrews and Jay Campbell. This highly reputable company located in Reno, Nevada offers a line of high-quality skin and hair care products and devices for men and women.

Expert Opinion

Board-certified dermatologist and professor Dr. Joshua Zeichner explains how red light therapy works to promote hair growth and health:

There is emerging data on the use of red light therapy for thinning hair. The thought is that red light enhances the delivery of oxygen and nutrients to the scalp to encourage optimal functioning of the hair follicles [1].

A 16-week study of men with androgenic alopecia published in Lasers in Surgery and Medicine by Raymond J Lanzafame, et al concluded that LED and red light laser treatments improved hair growth by 35% [2].

How Does it Work and What Are the Health Benefits?

The Aseir Red Light Brush employs blue and red light wavelengths to send photons of light into the cells to stimulate the mitochondria. As we explained in our review of HairMax, this increases the synthesis of ATP to power all of the body’s cells.

This helps reduce scalp inflammation, speed up healing, and stimulate the follicles to regenerate cells to promote growth and thickness. In addition, it increases hemoglobin levels to improve circulation. The added blood flow brings needed oxygen and nutrients to the scalp and follicles.

A review of the literature published in Skin Appendage Disorders by Andjela Egger, et al determined that low -evel light therapy is effective at treating pattern hair loss in men and women [3].

The red light wavelengths run from 630-680nm. As we said in our review of Hooga Health, the light delves just under the surface of the skin to the follicles for healing and growth benefits.

A systematic study of mice published in Nano Research by Shuang-Qiao Sun, et al showed the benefits of red LED light in promoting hair growth [4].

The Aseir Red Light Brush has blue wavelengths from 420-460nm, which penetrate slightly less deeply than red light, offering hair regrowth and benefits to the scalp like reduced swelling and tension and repair of damage.

A 10-week study published in Lasers in Medical Science by G Lodi, et al concluded that treatment with blue LED light improved hair density and width in 80% of androgenetic alopecia patients [5].

Side Effects and Risks

Research indicates that red and blue LED light therapy is safe and has no serious risks or side effects as long as you follow the directions as to use, treatment time, and frequency.

However, individuals with serious scalp conditions, tumors in the area, or open wounds should avoid using the product. If you are uncertain, check with a physician and get medical approval prior to use.
