The effectiveness of professional hair phototherapy using LED technology has been confirmed by several scientific studies conducted in renowned research centers. LED technology originated from advanced studies carried out in the United States, particularly by NASA, to better understand the influence of light on cell regeneration. It has even received the approval of a major organization like the Food and Drug Administration (FDA). The light produced by LEDs stimulates oxygen supply. By promoting cell regeneration, LED diodes ensure good hair regrowth. This "cold" light is painless.

Professional Hair Phototherapy — The science behind the technology

Professional hair phototherapy is one of the most fascinating advances in professional cosmetics in recent years. The Photon Therapy Lizze Extreme is the device that has democratized this technology in professional straightening salons: unique in the world in its 2-in-1 design, it combines two LED light wavelengths — blue and red — for two distinct and complementary uses. A tool that literally transforms the results of Brazilian straightening, Hair Botox, and coloring, while caring for the scalp and actively stimulating hair growth.

The effectiveness of this professional hair phototherapy has been confirmed by several scientific studies carried out in renowned research centers. LED technology originated from advanced research conducted notably by NASA to better understand the influence of light on cell regeneration. Validated by the FDA (U.S. Food and Drug Administration), it is based on a simple yet powerful principle: LED light stimulates oxygen supply at the cellular level, promotes cell regeneration, and allows active ingredients in hair products to penetrate much deeper into the hair fiber. This "cold" light is completely painless and has no thermal effect on the hair.

A unique 2-in-1 device: blue + red professional hair phototherapy

The Photon Lizze Extreme is the only device in the world to combine two different wavelengths of professional hair phototherapy in a single tool, each with a targeted and complementary action:

🔵 Blue LED Light — 450 nanometers Usage: during hair treatments (straightening, Hair Botox, coloring)

Blue light is the activator of treatments. Its 450-nanometer waves come into direct contact with the hair cuticle and initiate chemical reactions between the compounds of the product already distributed in the hair. These reactions enhance the effect of the product and prolong its durability by facilitating the penetration and fixation of active ingredients in the hair fibers.

Concrete result: by applying this blue LED professional hair phototherapy during the setting time of straightening, Hair Botox, or coloring, a visibly superior result is obtained — smoother, shinier, more durable — without changing the usual protocol.

Blue light applications:

• Brazilian, Indian, or tannin straightening: smoother, shinier result, prolonged hold
• Hair Botox: amplified active ingredient penetration, more nourishing and durable result
• Coloring: color penetrates deeper into the fiber — ideal for difficult-to-fix colors like red or brown
• All chemical hair treatments: enhances the result of any process

🔴 Red LED Light — 600 nanometers Usage: for the scalp — growth stimulation and strengthening

The red light of this professional hair phototherapy is specifically designed to treat the scalp. Its 600-nanometer waves penetrate deeper to activate blood microcirculation at the hair bulbs, stimulate and reactivate hair follicles, and strengthen the hair fiber at the root.

Red light actions:

• ✅ Stimulates hair growth by activating blood circulation
• ✅ Reactivates the hair bulb to limit hair loss
• ✅ Strengthens the hair fiber from the root
• ✅ Rebalances scalp pH for a healthier environment
• ✅ Treats oily root problems
• ✅ Promotes scalp cell regeneration
• ✅ Helps restore beautiful hair and optimal hair density

Red light application method: only on the roots, about 3 cm from them. Pass the red beam 3 times over each section of the scalp, separating the hair with a finger or clips.

What this professional hair phototherapy will change in your practice

For straightening professionals, the Photon represents an investment that directly translates into superior results for their clients:

• Straightening lasts longer — clients return less often, but with a higher satisfaction rate
• Colors hold better — especially red and brown tones which are notoriously difficult
• Clients observe visibly denser and stronger hair after several red professional hair phototherapy sessions
• A strong differentiating argument to offer a high-end service in the salon

Technical characteristics

• Brand: Lizze (Brazil)
• Technology: Dual wavelength LED (blue + red)
• Blue light: 450 nanometers — activation during hair treatments
• Red light: 600 nanometers — scalp stimulation
• LED class: Class 2
• Certification: Scientifically validated and FDA-approved technology
• Comes with: carrying bag, 2 pairs of protective glasses, instructions in French

⚠️ Safety — Glasses mandatory

The use of this professional hair phototherapy requires mandatory wearing of the protective glasses supplied with the device, for both people present:

• The professional operating the device
• The client receiving the treatment

Indeed, if the rays are directed at the client's back, they can be reflected by a mirror into the eyes. Protective glasses are included in the delivery (2 pairs).

How to integrate this professional hair phototherapy into your protocol

To enhance straightening, Hair Botox, or coloring (blue light):

1. Apply the straightening product, Hair Botox, or color to the hair according to the usual protocol
2. During the setting time, pass the blue LED professional hair phototherapy strand by strand over the lengths
3. Then let the product act normally and proceed with rinsing and straightening as usual

To stimulate growth and treat the scalp (red light):

1. On clean, dry hair, separate the hair into sections
2. Pass the red LED professional hair phototherapy about 3 cm from the roots
3. Perform 3 passes over each section of the scalp

❓ FAQ — Frequently asked questions about professional hair phototherapy

What is professional hair phototherapy and is it scientifically proven? Professional hair phototherapy uses LED light waves to act on the hair fiber and scalp. Its effectiveness has been confirmed by several scientific studies, notably from NASA research on cell regeneration through light. LED technology has also received FDA approval.

Can the Photon be used alone, without a straightening product? Yes, red light can be used alone to treat the scalp, stimulate growth, and rebalance pH without any other product. Blue light, on the other hand, is designed to be used in conjunction with a hair treatment (straightening, Hair Botox, coloring) to enhance its effects.

Is the Photon painful or dangerous? No, this professional hair phototherapy uses "cold" light that is completely painless and has no thermal effect on the hair or scalp. It is safe when used with the protective glasses provided.

How long is the Photon used on the hair during straightening? The blue light professional hair phototherapy is passed strand by strand during the setting time of the straightening product or Hair Botox. The duration varies depending on the length and thickness of the hair. For the scalp with red light, 3 passes are made per section.

Is the Photon compatible with all straighteners available on Paris Liss? Yes, this professional hair phototherapy is compatible with all straighteners and treatments available on Paris Liss: Brazilian, Indian, tannin, Tahitian straightening, Hair Botox. It enhances the result of any professional hair treatment.

Can the Photon help with hair loss? The red light of this professional hair phototherapy is specifically designed to stimulate blood circulation at the hair bulbs and reactivate hair follicles. It can help reduce hair loss and stimulate growth with regular use.

To be used during chemical processes

• Coloring/bleaching: better coverage on white and difficult hair. Better retention of fragile pigments like vibrant colors (red, copper, etc.)
• Straightening: guarantees a result even on difficult hair. Allows for reduced product processing time (time saving)
• Hair Botox: the treatment will act deeply and guarantee a lasting result
• Neutralizer: the neutralizer will act deeply and faster
• Perm: better hold and reduced processing time

It is a stimulant to maximize results and save time. The effectiveness of this professional hair phototherapy is proven (video available upon request).
