LED Light Therapy: Everything You Need to Know About LED Benefits in Haircare

LED therapy takes advantage of these light-induced benefits to address a myriad of beauty concerns from acne to sun damage to skin aging. But what makes LEDs, light-emitting diodes, so special?

NASA initially developed LEDs for their space plant growth experiments, but studies soon found evidence that LED light had amazing healing properties and could accelerate tissue growth. In fact, Navy SEALS actively use LED therapy to help heal wounds and treat sore muscles. As it turns out, these studies have shown a promising benefit of longterm LED therapy not only for your health, but also for your beauty routine.

How does LED therapy work?

Scientists have shown that light can penetrate your skin to activate the skin’s (and your scalp’s) natural healing processes. Different wavelengths (read: colors) of light serve different purposes and penetrate your skin to different depths. LED therapy has been found effective at combatting everything from acne to aging concerns, scarring, inflammation, sun damage, and more.

The best part is that LED treatments are completely non-invasive and do not contain UV rays! That means that LED therapy is suitable for long-term use and is safe for all skin tones. In fact, regular use is encouraged to achieve long-lasting results.

Invest in an at-home LED device to save money and time on weekly appointments. Both the RÉDUIT One and the RÉDUIT One Gold are compatible with the new LED Hairpods™, which activate LED light of different wavelengths to treat haircare concerns and boost the performance of our unique formulations.

LED Therapy in Haircare

Odds are you’ve seen a number of LED devices that have been designed to supplement your skincare routine, but LED therapy is thought to be equally as beneficial for your hair. Below are a few LED colors that RÉDUIT’s technicians have determined will transform your hair from the inside out.

Blue Light

Blue LED therapy has a calming effect on the skin and scalp, specifically by reducing inflammation. Blue light also targets acne-causing bacteria, reduces the activity of oil-producing glands, and has a positive skin-tightening effect to make your hair more manageable from within.

RÉDUIT’s new Precision Conditioner LED Hairpods™ apply Blue LED therapy to treat your scalp and support healthier hair growth.

Green Light

Green LED therapy helps to normalize the activity of sebaceous glands and control oil production. Sebaceous glands are oil-producing glands located beneath your hair follicles that lubricate your scalp and hair and prevent them from drying out. However, these glands can become overactive, causing your skin and hair to become oily. Green LED therapy helps bring overactive sebaceous glands under control and restore a healthy oil vs. moisture balance to your scalp, while giving your hair a beautiful shine.

Red Light

Red LED light stimulates collagen production to reduce the appearance of scarring and slow the signs of aging. Red LED therapy also improves circulation in the scalp to reduce inflammation and promote hair growth and health. It has also shown to be an effective treatment for rosacea and some other skin conditions, which can affect the scalp or the skin near your hairline.

Cyan Light

Cyan LED light has an anti-inflammatory effect that effectively treats and soothes sun damage and restores the health of the scalp and hair after sun exposure. Cyan LED therapy reduces swollen capillaries and helps release cellular stress to enhance the hair and scalp cell energy.

Purple Light

Purple LED therapy gives you the combined benefits of red and blue light simultaneously.  Purple light increases cell rejuvenation and renewal, bringing longterm benefits to scalp health and hair. It also slows hair and skin aging, produces a calming effect for your scalp, and works to promote strong hair growth.
