The power of red and blue light for hair health and beauty

Introduction: When science meets beauty

Hair care is no longer just about shampoos and masks. In recent years, a technology derived from aesthetic medicine has entered the world of beauty: LED photobiomodulation .
Already used in dermatological clinics to stimulate skin regeneration, this technique is now accessible at home thanks to innovative devices such as the Helia Hair™ LED brush .

The goal? To awaken the natural potential of hair thanks to two specific wavelengths: red and blue . These two colors, far from being chosen at random, exert complementary effects on the scalp and hair follicles.

🔴 Red light (≈650 nm): activates growth at the root

Red light is a real source of energy for hair cells .

1. Stimulation of microcirculation
   By penetrating beneath the epidermis, red light activates blood circulation in the scalp. The result: an increased supply of oxygen and nutrients to the hair follicles.
2. Production of ATP (cellular energy)
   Cells absorb light and produce more ATP, the “biological fuel” essential for regeneration. This mechanism explains the direct stimulation of hair growth.
3. Slowing the fall
   Red light helps prolong the growth phase (anagen) of the hair, thus limiting premature loss.

Concretely, red light acts as a natural fertilizer , reactivating dormant follicles and strengthening existing roots.

🔵 Blue light (≈470 nm): purifies and balances the scalp

If red acts deep down, blue works on the surface to create a healthy and balanced environment .

1. Antibacterial and purifying action
   Blue light eliminates bacteria responsible for irritation and inflammation.
2. Sebum regulation
   By acting on the sebaceous glands, it reduces excess sebum which can suffocate the follicles.
3. Soothing irritations
   Thanks to its calming effect, blue light relieves itching and redness, promoting a healthy and soothed scalp.

Simply put, blue light acts as an invisible cleanser , preparing the ground for optimal growth.

A unique synergy: red + blue

Maximum efficiency is achieved when these two technologies are used together .

• Red energizes and nourishes the follicles.
• Blue cleanses and balances the scalp.

This combination creates a virtuous circle: a purified and stimulated scalp allows hair to grow faster, stronger and shinier.

What the research says

Scientific publications confirm the benefits of photobiomodulation:

• 19% average hair density after 6 months of regular use.
• Significant reduction in hair loss in people with mild to moderate alopecia.
• Visible improvement in scalp quality.

👉 These clinical results reinforce the legitimacy of Helia Hair™ as a premium solution in hair care.

Conclusion: an avant-garde beauty ritual

Red and blue light are not just colors: they represent a new approach to hair care, based on science and technology.

With Helia Hair™ , every use becomes a ritual combining pleasure, efficiency and innovation . Give your hair more than a treatment: a rebirth.
