Growcel Gran Pro: When hair care takes on the logic of a serum
Share
Why hair care is still a step behind skincare
In skincare today, no one doubts that hydration alone is not enough. We know that the key lies in active ingredients that reach the correct depth, communicate with cells, and address the cause, not just the superficial symptom. Serum essences, peptides, stem cells, hyaluronic acid, and growth factors are commonplace in the world of facial care.
In the world of hair cosmetics, this logic has long been missing. Shampoo was shampoo. Conditioner was conditioner. Products were mainly judged by how hair smelled, how much lather they produced, and how hair felt after rinsing.
Growcel Gran Pro by Esthe Pro Labo rejects this approach.
What serum logic applied to hair means
The serum logic of hair care rests on two axes that most products on the market either separate or do not consider at all.
The first axis is the scalp. Hair does not grow in a vacuum. It grows from a follicle rooted in the skin, which has its pH, its microflora, its circulation, and its ability to deliver nutrients to the follicle. If the scalp is imbalanced, irritated, dehydrated, or has a compromised barrier, it directly affects hair quality: its strength, growth rate, breakage, and overall treatment results.
The second axis is the hair fiber itself, its cuticle, cortex, and CMC structure—the intercellular cement substance that holds hair cells together and determines whether hair looks healthy or not.
Growcel Gran Pro works with both axes simultaneously. This is the factual content of the concept of double serum hair care: one axis cares for the environment from which the hair grows, the other axis cares for the hair fiber that emerges from this environment.
Shared technological platform of the entire range
Before we move on to individual products, it's important to understand what all four have in common. Growcel Gran Pro is not a collection of randomly assembled products under one brand. It is a system built on shared active complexes.
Plant stem cells from three sources permeate the entire range. Edelweiss stem cells provide antioxidant protection and resilience typical of this extremely adaptable mountain flower. Gardenia stem cells support regeneration and cellular renewal. Mung bean stem cells stimulate follicles and strengthen the natural hair growth cycle. Together, these three cellular sources aim to regenerate follicles and revitalize the scalp at a level that conventional hair cosmetics do not reach.
The complex of 16 amino acids includes hydroxyproline, arginine, taurine, lysine, glutamic acid, glycine, leucine, histidine, serine, valine, sodium aspartate, threonine, alanine, isoleucine, proline, phenylalanine, and tyrosine. In the context of hair care, amino acids are not a superficial ingredient. Hair is primarily made of keratin, a protein composed of amino acid chains. Providing amino acids to the hair fiber from the outside means giving it the building blocks it needs to repair damaged structures.
Herbal extracts are repeated in various combinations throughout the range: extracts of skullcap (Scutellaria baicalensis), licorice, rosemary, Gotu Kola, allantoin, and others. Their role is anti-inflammatory, antioxidant, and soothing, which is exactly what the scalp needs as a foundation for a healthy hair follicle environment.
Fast Pro Water and KEISO Nano Premium are technological components that support deep penetration of active ingredients. Fast Pro Water stimulates aquaporin channels in cell membranes, thereby increasing the skin's permeability to active ingredients. KEISO Nano Premium, specially processed silica, contributes to the luminous effect and smoothness of the hair fiber.
Growcel Shampoo Gran Pro: cleansing as the first step in serum care
The classic approach to shampoo is functional: wash hair, remove oil and dirt, lather. Growcel Shampoo Gran Pro embraces and transcends this approach.
The cleansing base is built on amino acid surfactants, specifically glutamic acid and cocoyl glutamate derivatives, which clean more gently than sulfates while respecting the scalp's natural pH. This choice is not accidental: the scalp has a naturally slightly acidic pH of around 5, and any shampoo that disrupts it towards alkalinity compromises the natural barrier and microflora of the scalp.
In addition to the shared complex of stem cells, amino acids, and herbal extracts, the shampoo contains hydrolyzed cashmere keratin, which restores the hair cuticle and increases its shine and resistance. Soluble collagen provides surface hydration, and glucosyl hesperidin adds an antioxidant and blood circulation-boosting effect to the scalp. Proteoglycan in the composition helps retain moisture at the skin tissue level.
The result is a shampoo that itself provides a conditioning and nourishing effect, not just paving the way for subsequent care, but initiating it.
Growcel Treatment Gran Pro: regenerating conditioner with deep nourishment
Growcel Treatment Gran Pro is a regenerating hair fiber treatment, built on an emulsion base of natural fatty alcohols and esters, free of sulfates and silicones.
The silicone-free formulation is a conscious choice with a direct impact on the result. Silicones create a film on the hair that provides an immediate feeling of smoothness but also prevents active ingredients from penetrating the hair fiber and gradually accumulates on it. Growcel Treatment opts for deep nourishment instead of a superficial effect.
The central ingredients are two types of keratin: cashmere keratin and wool keratin. They differ in molecular structure and complement each other's effects on different layers of the hair fiber. Cashmere keratin, with finer molecules, penetrates deeper into the cortex, while wool keratin works with the cuticle and the hair's surface structure. Hydrolyzed silk adds shine and slipperiness, which facilitates detangling and reduces mechanical hair damage.
Collagen in the composition supports the renewal of the hair's CMC structure, the intercellular substance whose loss is responsible for brittleness, split ends, and overall dullness of the hair. Sodium metasilicate adds a radiant effect that is visible immediately after the first use.
Plant extracts of green tea, rosemary, Gotu Kola, and chamomile, combined with allantoin, form a soothing and antioxidant care layer that prepares the scalp for optimal follicle function.
The treatment is applied to wet hair and left on for ten to fifteen minutes. This time is not just a recommendation. It is a technical necessity: deep diffusion of active ingredients into the hair fiber requires time and warmth from the hair follicle.
Growcel Hair Oil Gran Pro: final care without silicones, with nine plant oils
Growcel Hair Oil Gran Pro concludes the hair ritual as a leave-in treatment that is not rinsed out. Its philosophy is simple: after washing and conditioning, hair needs protection from mechanical and heat damage, UV radiation, and moisture loss. And this protection should be provided by a natural, not synthetic, base.
The formulation is based on nine plant oils: olive oil as a base with oleic acid, rice oil rich in gamma-oryzanol, argan oil for dense nourishment, macadamia ethyl ester for lightness and non-greasiness, squalane for exceptional compatibility with hair fiber lipids, and others. Each oil brings a different molecular size and a different fatty acid profile, so together they cover hair fiber nourishment on multiple layers.
Isostearoyl hydrolyzed collagen is esterified collagen, a form of collagen with a high affinity for the hair fiber. Unlike unmodified hydrolyzed collagen, which remains on the surface, this form penetrates the cuticle and supports the renewal of the CMC layer. Laminaria extract (golden algae) adds marine minerals, polysaccharides, and iodine, which hydrate and strengthen the hair fiber at a cellular level.
Tocopherol, natural vitamin E, protects all plant oils and the hair itself from oxidation and UV damage. Essential oils of bergamot, orange peel, ylang-ylang, chamomile, and geranium provide a sensory experience during application and also add a soothing effect to the scalp when massaged.
The product is free of silicones, parabens, synthetic fragrances, alcohol, and mineral oils. It is applied to wet or dry hair and does not require rinsing.
Growcel Body Soap Gran Pro: serum logic for the whole body
Growcel Gran Pro is not just a hair line. Body Soap Gran Pro extends the same philosophy to body skin care: gentle cleansing with an immediate nourishing effect, based on amino acid surfactants and active ingredients with full-fledged care.
The cleansing base combines potassium cocoyl glutamate and sodium cocoyl glutamate, which are natural amino-acid surfactants that maintain the skin's natural pH and minimize transepidermal water loss after each shower. Betaine, as a natural humectant, retains moisture in the skin even after rinsing.
The shared complex of stem cells from edelweiss, gardenia, and mung bean, the complex of 16 amino acids, and herbal extracts from skullcap, Gotu Kola, licorice, and rosemary work in the shower formula just as they do in the hair line: they provide active care, not just a cleansing effect.
Additionally, it contains soluble proteoglycan, a hygroscopic macromolecule naturally present in the dermis, which contributes to water retention in tissues and skin elasticity. Rosa roxburghii, or Roxburgh rose hips, one of the most concentrated natural sources of vitamin C, adds antioxidant protection and supports natural collagen synthesis. Artichoke leaf extract and Polygonum cuspidatum provide resveratrol and anti-inflammatory flavonoids.
The result is a shower gel that leaves the skin truly nourished, not just clean.
How the Growcel routine works as a system
The four Growcel Gran Pro products are not four independent choices. They are layered so that each step builds on the previous one and prepares the conditions for the next.
The shampoo with amino acid surfactants gently opens the cuticle, cleanses the scalp without disrupting its pH, and delivers the first layer of active care through stem cells and keratin. The Treatment with cashmere and wool keratin, silk, and collagen fills damaged hair fiber structures and, during its fifteen-minute action, restores the CMC layers. The Hair Oil closes the cuticle, protects the treatment's results, and provides nourishment that does not wash away the first two steps but protects their effect. The Body Soap extends the same logic to the entire body and completes the shower ritual with a feeling of care, not just cleanliness.
Who is Growcel Gran Pro for
Growcel Gran Pro is a choice for anyone looking for hair care that takes hair and scalp as seriously as skincare takes facial skin. It will particularly appeal to those who struggle with hair breakage, dryness, or loss of vitality, who have colored or chemically treated hair with compromised cuticle structure, who experience scalp irritation or imbalance, or who simply want hair care without compromise in ingredient purity.
The range is suitable for sensitive scalps and does not require a transition: each product works independently, and the system as a whole delivers a synergistic result.
Internal nutrition as a foundation: why external care alone is not enough
Growcel Gran Pro works on the scalp and hair fiber from the outside. But hair grows from within. And the quality of what emerges from the follicle depends on what the body receives in diet and supplements.
Hair is approximately 90 percent keratin, a structural protein. Nails have a very similar composition. The body synthesizes keratin from amino acids it receives through food. If protein intake is insufficient or if the body cannot synthesize enough building material from the proteins it receives, it directly affects the quality of the hair fiber: its strength, elasticity, density, and growth rate. The same applies to nails, which become brittle, grow poorly, or lose their natural shine.
External care can restore the hair surface and prepare the scalp as an optimal environment for the follicle. But if the body has no keratin to build from, the results of external care will hit their ceiling.
Protein Natura Gran Pro: internal nutrition for hair, nails, and overall vitality
Protein Natura Gran Pro by Esthe Pro Labo is a functional plant protein that systematically addresses this internal layer of nutrition. It combines three complementary sources of plant proteins: soy protein, pea protein, and sprouted brown rice protein. Each brings a different spectrum of amino acids, and their combination ensures that the body receives the complete amino acid profile needed for the synthesis of keratin and other structural proteins.
Soy protein contains all essential amino acids. Pea protein excels in arginine and leucine content, amino acids crucial for cellular proliferation and muscle metabolism. Sprouted brown rice protein is easily digestible and hypoallergenic, making it suitable even for sensitive digestive systems.
However, the formula goes beyond mere protein. It contains oat powder with beta-glucans to support digestion and metabolism, chia seeds and black sesame rich in omega fatty acids and minerals, fermented koji extract for enzymatic support of nutrient absorption, and a complex of green superfoods: kale, moringa, and broccoli, rich in B, C, and E vitamins and trace elements like iron and zinc, which play a direct role in the natural synthesis of keratin and in the metabolism of hair follicles.
Dolomite and natural calcium in the composition supplement the mineral base, which is also essential for nail strength and hair fiber quality. Fermented Euglena gracilis, a microalga with a complete amino acid profile and chlorophyll, adds antioxidant protection at the cellular level.
Protein Natura Gran Pro is not a classic sports protein. It is a functional inner beauty supplement that provides the body with building blocks for keratin formation, enzymatic support for its synthesis, and micronutrients needed for a healthy hair cycle and nail strength.
One sachet daily dissolved in 150 to 200 ml of water or soy milk complements the Growcel routine with an internal layer of nutrition, without which even the best external care only works with what the follicle offers.
How external and internal care work together
The synergy of Growcel Gran Pro and Protein Natura Gran Pro is based on a simple principle that byFEMME applies across its entire portfolio: external care optimizes the environment and structure, while internal care provides material and energy. Separately, they work on different layers. Combined, they enhance each other.
