Clients arrive at the salon asking for "the Plex treatment I saw on social media" or "that bleach that doesn't damage hair", and they talk about hair epigenetics and plant stem cells as if they were public domain concepts. The reality is that few professionals know the science behind these latest-generation technologies.
In a market saturated with commercial promises, distinguishing genuine innovation from empty marketing is a necessity. And that's where working with manufacturers who develop their own formulas in the lab makes the difference compared to brands that only label generic products.
Main Conclusions
The essentials about the three technologies and about who should develop them, summarized in five keys:
What is Plex Technology Really and How Does It Work?
Plex technology has transformed professional bleaching and coloring processes. Beyond the commercial term, it is a chemical system that rebuilds the disulfide bridges broken during aggressive technical treatments.
Hair is made of keratin proteins joined by these bridges. Every chemical intervention —coloring, bleaching, straightening— breaks those structural bonds and leaves the fiber weakened and prone to breakage.
Plex treatments act as bond multipliers that restore these unions at a molecular level. Unlike surface treatments that only hydrate, Plex products penetrate the cortex to repair the internal structure.
Plex treatments look for hydrogen and sulfur bonds and rejoin them to create stable disulfide bonds inside the hair fiber.
Clinical studies indicate that Plex technology can reduce hair breakage by up to 95% during intensive bleaching processes, according to data published by specialized manufacturers in professional bleaching. This protection is directly integrated into solutions such as bleaching powder with Plex, designed for high-performance lightening.
Professional Plex systems are usually applied in three phases, each with a specific function in protecting and repairing the fiber.
- Step 1 (Protector)
- added to the dye or bleach mixture and protects in real time
- Step 2 (Repairer)
- applied after rinsing, with 10-15 min exposure time
- Step 3 (Maintenance)
- product for home use between salon visits
This structure allows the professional to control the level of protection according to the intensity of the service, from a soft coloring to a 9-tone bleaching.
💡 Technical tip: adjust the Step 1 dose to the volume of oxidant and the planned level of lightening; the more aggressive the process, the greater the need for protection in the mixture.
Hair Epigenetics: Marketing or Real Science?
The term "epigenetics" sounds like science fiction, but it is a legitimate biomedical research field with real application in professional cosmetics. Epigenetics studies changes in gene expression that do not alter the DNA sequence.
In practical terms, we are talking about active ingredients capable of "turning on" or "turning off" specific genes without permanently modifying the genetic code. Applied to hair, certain active principles can influence genes related to hair loss, follicle growth, and scalp aging.
Epigenetics applied in cosmetics seeks to activate cellular regeneration mechanisms and normalize the synthesis of proteins responsible for providing elasticity to the skin that are lost with age.
Hair epigenetic treatments incorporate complexes such as microRNAs, which act as molecular switches. Clinical studies demonstrate their ability to stimulate the proliferation of dermal papilla cells, fundamental for hair growth.
These treatments do not regenerate destroyed follicles —that would be medicine, not cosmetics— but rather optimize the function of existing follicles. According to studies under dermatological supervision published by HD Cosmetic Efficiency, protocols applied for 84 days showed significant increases in hair area and density.
The clinically documented benefits are summarized as follows:
| Benefit | Documented data |
|---|---|
| Thickness increase (normal hair) | up to 19.30% |
| Thickness increase (very fine hair) | up to 47% |
| Improvement in fibroblast synthesis and vitality | 70% |
| Hair loss | visible reduction due to follicle reinforcement |
| Mitochondrial DNA | protection against oxidative stress |
These data contrast with generic white label products that use the term "epigenetics" without clinical studies to back their claims.
Plant Stem Cells: Beyond Green Marketing
Plant stem cells are another biotechnological advance with real application in hair cosmetics. But it is fundamental to understand what they are and what they are not.
Plant stem cells used in cosmetics are not living cells. They are concentrated extracts derived from stem cells of specific plants, obtained through laboratory cultivation, containing bioactive molecules capable of stimulating natural defense and repair mechanisms of the fiber.
The most used species is the Swiss apple Uttwiler Spätlauber, whose high concentration of stem cells allows it to stay fresh months after harvesting. Grape, argan, edelweiss, and ginseng extracts are also used.
According to information published in Revista Coiffure, 2024 scientific studies published in Nature indicate that treatments based on these extracts can increase the number of hairs by between 15% and 30% compared to conventional approaches.
The extracts provide three main benefits, documented in cosmetic efficacy studies from independent laboratories.
- Deep regeneration
- they penetrate the cortex and renew the fiber from the core
- Antioxidant protection
- phytochemicals that stop free radicals, UV, and pollution
- Anti-aging effect
- they maintain the fiber's protein chains
Plant stem cells are not magic, but they are a powerful tool to stimulate the natural regeneration of skin and hair.
It is advisable to manage expectations: these active ingredients improve the quality of the existing fiber, they do not regenerate destroyed follicles or reverse advanced alopecia. They are high-level cosmetic tools, present in treatments such as the anti-aging with stem cells and collagen, not substitutes for medical treatments.
Manufacturer or Labeler: Why It Matters Who Develops the Formula
In the professional market, two radically different models coexist: manufacturers with their own R&D and brands that label generic products.
A real manufacturer has its own research laboratories, certified production plants, and total control of the process, from raw material to packaging. It develops its own technologies, patents them, and improves them continuously.
A labeling brand buys already formulated products from third parties (white label or private label model), adds its logo, and markets them. It does not invest in R&D or control quality beyond what the external manufacturer guarantees.
According to information published by MS Lab Cosmetics, the global white label cosmetics market reached $1.01 billion in 2024.
The difference for the salon is decisive: a manufacturer can adjust formulas, incorporate technologies quickly, and guarantee full traceability. A labeler depends on third parties and offers the same base product as dozens of competitors. There are clear signs to distinguish them:
| Sign | Real manufacturer | Labeler |
|---|---|---|
| Certifications (ISO 9001, 22716) | in their own name | absent or from third parties |
| Production facilities | identifiable | no information |
| Own clinical studies | with methodology and data | unsupported terms |
| Customization and development | custom-made | generic formulas |
| Product continuity | stable | supplier changes |
Working with a real manufacturer means access to genuine technical knowledge, not just products. Training from a manufacturer with its own laboratory has a different value than that of a mere marketer.
The Economic Impact of Choosing a Manufacturer Over Intermediaries
Beyond technical quality, the choice has direct economic implications for the salon. Direct manufacturers eliminate distribution layers, which translates into a better quality-price ratio.
According to sector analysis published in Trylab, private label products can reach margins of 50-70% compared to 30-50% for generic white label products. For the salon, this translates into offering cutting-edge technical services at competitive prices, improving profitability without compromising results.
In addition, manufacturers with their own R&D react quickly to trends. When a new demand arises —the curly method boom or vegan treatments— a real manufacturer develops and launches a product in months; a labeler must wait for their external supplier to offer it.
💡 Buying tip: before incorporating a brand, ask for its certifications in its own name and the clinical studies of its star active ingredients; their availability separates the manufacturer from the simple labeler.
Yanguas Professional: When Technology is Born in the Own Laboratory
Yanguas Professional exemplifies the integrated manufacturer model with its own R&D. With more than three decades of experience and ISO 9001 and ISO 22716 certified plants in Tudela (Navarra), it develops technologies such as its Plex system in high-performance bleaches, anti-hair loss epigenetic treatments, and formulations with plant stem cells.
The difference between a manufacturer and a labeler is evidenced in the ability to explain how each active ingredient works, what concentration is used, and what studies back it up. When a salon works with a direct manufacturer, it doesn't just buy a product: it accesses genuine technical knowledge that it can pass on to its clientele with confidence.
In a market saturated with empty promises, Plex technologies, epigenetics, and plant stem cells represent legitimate scientific advances, but only when they come from manufacturers with real R&D capacity and their own production.
Frequently Asked Questions
What exactly does Plex technology do during bleaching?
It rebuilds the disulfide bridges that bleaching breaks in the hair's keratin. It is applied in phases —protection in the mixture, repair after rinsing, and home maintenance— and can reduce breakage by up to 95% in intensive processes.
Does hair epigenetics change my genes permanently?
No. Epigenetics acts on gene expression —"turns on" or "turns off" genes— without altering the DNA sequence. Applied to the hair, it optimizes the function of existing follicles, but does not regenerate already destroyed follicles.
Are plant stem cells living cells?
No. They are concentrated extracts obtained by laboratory cultivation from stem cells of plants such as the Uttwiler Spätlauber apple. They contain bioactive molecules that stimulate the repair and protection of the fiber, not living organisms.
Can these treatments reverse alopecia?
No. They improve the quality of the existing fiber and reinforce active follicles, but they do not reverse advanced alopecia processes or replace medical treatments. They are high-level cosmetic tools, not medicine.
How do I know if a brand manufactures or only labels the product?
A real manufacturer presents ISO certifications in its own name, identifiable facilities, clinical studies with methodology, and custom development capacity. A labeler lacks information about its production and uses generic formulas without documented scientific backing.
