Damaged hair almost never has just one problem. It usually has three at once: a lack of internal strength, a lack of lipids, and a lack of water. Understanding what's happening at each of these levels helps in choosing the right active ingredients and stops the search for a single miracle solution, when synergy is what's needed.
What really damages hair
Before talking about active ingredients, let's take a quick look at the most common aggressions:
- Chemical: coloring, bleaching, straightening, perming: alter the internal bonds of keratin.
- Thermal: straighteners, hairdryers, curling irons: weaken the cuticle, dehydrate by evaporation.
- Mechanical: brushing, friction, repeated styling: lift the cuticle scales.
- Environmental: UV, pollution, hard water: accelerate oxidation and lipid depletion.
These aggressions have one thing in common: they deplete the hair fiber of three specific elements: proteins, lipids, water. These three pillars should guide the choice of a repairing treatment.
In short: the 3 pillars of repaired hair
- Proteins: restore strength and hold to the fiber
- Lipids: restore suppleness, cohesion, and shine
- Hydration: provides suppleness and comfort, for hair less prone to breakage
Pillar 1: Proteins, to restore strength to the fiber
Hair is composed of more than 90% keratin, a fibrous protein. When the internal bonds of this keratin are broken by repeated aggressions, hair loses strength and elasticity.
Plant-based amino acids and peptides lodge in the weakened areas of the fiber. Well-dosed and combined with other active ingredients, they help reinforce its appearance and facilitate styling, without ever weighing it down.
In BLOWN formulas: this role is carried by TRI-AMINO, a synergy of wheat, corn, and soy proteins present in the Shampoo. Plant-based amino acids and peptides help reinforce the fiber's appearance and facilitate styling.
Pillar 2: Lipids, to restore suppleness and shine
Proteins restore strength, but they are not enough: without lipids, protein-rich hair can become coarse and dull. Lipids play a dual role: they maintain the cohesion of the cuticle scales and rebuild the surface film that protects and makes the fiber shine.
In BLOWN formulas: two complexes are involved in this pillar.
- KERA-LIPID (Mask): plant-based amino acids and peptides, hydrolyzed collagen, and five oils (shea, coconut, castor, avocado, jojoba). It nourishes and helps repair the fiber, for smoother hair.
- HYDRO-SEAL & REPAIR (Leave-In Detangler): amino acids, plant-based peptides, and plant-derived squalene. It helps repair the appearance of split ends and reduce styling-related breakage, without weighing hair down.
Pillar 3: Hydration, the often-forgotten pillar
Proteins and lipids usually take center stage in discussions about hair repair. Hydration, however, is less often highlighted, wrongly so. Dry hair loses suppleness, becomes more prone to breakage during styling, and tangles more easily.
Hyaluronic acid and plant polysaccharides help retain water within the fiber, for a silky feel without a heavy effect.
In BLOWN formulas: this is the role of HYDRA-SILK (Ultimate Repairing Mask). Hyaluronic acid and plant polysaccharide help hydrate the fiber, for a silky feel without weighing hair down.
Why combine the three pillars rather than isolating a single active ingredient
This is the most common mistake in hair routines: multiplying protein treatments without lipid intake, or vice versa, without ever addressing hydration.
Damaged hair needs all three inputs simultaneously, in proportions adapted to the extent of the damage. This logic of synergy, rather than the addition of isolated active ingredients, structures the architecture of the eight BLOWN complexes, from Shampoo to the Magic Mist.
BLOWN clinical results
BLOWN complexes underwent a clinical evaluation in 2025, based on a 28-day self-assessment by 20 volunteers, under dermatological supervision. The results, expressed as a percentage of volunteers satisfied by criterion:
| Product | Key Results |
|---|---|
| Mask | 100% on all evaluated efficacy criteria · 90% purchase intent and recommendation |
| Detangler | 100% on ease of detangling and all comfort criteria · 95% on perceived reduction in breakage |
| Shampoo | 90% on softness, shine, perceived hydration, and perceived reduction in breakage |
| Mist | 100% on thermal protection and perceived hydration · 95% on perceived reduction in breakage |
These data reflect the perception of volunteers within the framework of this supervised self-assessment; they do not replace an individual hair diagnosis.
FAQ: Repairing Active Ingredients, The Essentials
What are the best active ingredients to repair damaged hair?
Three families of active ingredients work complementarily: proteins and amino acids (internal strength of the fiber), lipids such as vegetable oils and squalene (cuticle cohesion, suppleness), and moisturizing agents such as hyaluronic acid (water retention in the fiber).
