PEH Balance stands for the balance of Proteins, Emollients and Hydration in the hair — three essential elements that keep hair strong, smooth and well hydrated.
PROTEINS
A multi-molecular protein complex reinforces the hair fibre across different levels:
Low-molecular-weight fractions penetrate the cortex, improving resistance to stretching;
High-molecular-weight fractions form a flexible surface network that helps protect the cuticle from mechanical stress.
EMOLLIENTS
Lipopeptide chia forms a lightweight, flexible biofilm that mimics the natural cuticle.
It smooths the surface, reduces friction, enhances softness and shine with a protective, weightless feel.
HYDRATION
A biomimetic amino acid complex inspired by amino acids naturally present in the hair attracts and retains moisture within the fibre.
It supports elasticity, flexibility and long-lasting hydration, even under heat stress.

“I use heat on my hair pretty often, so this has become a must for me. My hair feels softer and smoother after styling and the ends don't feel as dry. It's really lightweight, doesn't weigh my hair down and leaves it looking healthy and shiny.”

THE ACTIVES BEHIND THE FORMULA
Amino Acid Complex
Amino acids are a key part of the Cell Membrane Complex (CMC), the structure that connects hair cells and keeps the fibre cohesive. Within the CMC, they work synergistically with lipids to create an optimal environment for hair: retaining moisture, supporting cell cohesion and maintaining structural stability.
Built on this biological principle, the blend mirrors the naturally occurring amino acid composition of the CMC.
Supports the H component of the PEH Balance system by maintaining optimal moisture levels while preserving flexibility and resilience. Keeps the hair hydrated, supple and balanced. Improves elasticity, enhances softness and reduces brittleness.
PCA (Pyrrolidone Carboxylic Acid)
Naturally present in the hair, PCA plays a central role in fibre hydration. It attracts and binds water within the fibre, maintaining stable and consistent hydration levels.
Supports the H component of the PEH Balance system by improving moisture retention under daily stress. Maintains flexibility and softness while reducing dryness and stiffness. Improves suppleness, enhances manageability and supports long-lasting hydration.
Chia Lipopeptide
A next-generation biomimetic molecule designed to support PEH balance. Forms a structured biofilm on the hair surface that mimics cuticle function.
The lipid fraction acts as a source of emollients, improving smoothness and surface integrity. The peptide fraction supports protein balance and hydration, maintaining flexibility and elasticity.
Supports the full PEH Balance system, helping maintain the right balance between proteins, emollients and hydration. Maintains balance without weighing the hair down and supports the hair structure where it is most needed.
Multi-Molecular Protein Complex
Reinforces hair strength against different types of mechanical stress. Acts on three key parameters of hair resistance: tensile strength, bending resilience and cuticle integrity. As a multi-molecular system, the complex works across different levels of the hair fibre.
Low-molecular fractions penetrate the cortex, strengthening the internal structure and improving resistance to stretching. High-molecular fractions form a flexible surface network, reducing friction and protecting the cuticle from mechanical wear.
Supports the P component of the PEH Balance system by reinforcing protein structure while maintaining flexibility and preventing stiffness. Improves elasticity, reduces breakage and enhances resistance to daily stress from brushing, styling and environmental exposure.
VOEY EXPERT TIP
Apply to dry hair between washes to smooth the surface, restore softness and maintain a hydrated, polished feel without weighing the hair down.
It forms a lightweight protective layer around the hair fibre, helping reduce heat damage at temperatures of up to 230°C. It also supports hydration, smoothness and manageability during styling.
Can I apply it to dry hair?
Yes. It can be applied to dry hair before using hot styling tools or whenever the hair needs additional hydration and smoothness. Allow the product to dry completely before using straighteners or curling irons.
Can I use it without heat styling?
Yes. You can apply it at any time to help hydrate the hair, reduce frizz and improve softness and manageability, even when no heat tools are used.
Will it weigh down my hair?
No. The lightweight formula is designed to protect and condition without leaving the hair feeling heavy or greasy. For fine hair, apply a small amount mainly to the mid-lengths and ends.
Will it cause build-up on my hair?
The formula uses advanced film-forming and conditioning ingredients designed to create a lightweight protective layer without leaving heavy residue or causing build-up. Hair remains soft, light and easy to manage.
Is it suitable for all hair types?
Yes. It is suitable for all hair types, including fine, curly, coloured, bleached and chemically treated hair. Adjust the amount according to your hair’s length, thickness and condition.
How often can I use it?
You can use it every time you wash or heat-style your hair. It can also be reapplied between washes when the hair needs additional hydration or protection.
Is the formula vegan?
Yes. The formula is vegan and contains no animal-derived ingredients.
What does PEH Thermal Shield smell like?
It has a refined, elegant fragrance inspired by fine perfumery. The scent leaves the hair delicately fragranced without feeling overpowering.
What does PEH stand for?
PEH stands for Proteins, Emollients and Hydration. Proteins help reinforce weakened areas of the hair, emollients smooth the cuticle and improve softness, while hydration helps maintain moisture and flexibility.
My hair is much easier to detangle and it is not greasy or heavy.
Il hydrate tout en protégeant super bien de la chaleur ! je l'adore excellent produit
Spray ultra léger, on ne le sent pas du tout sur les cheveux.
Really impressed with this spray. My hair is much easier to detangle and it is not greasy or heavy. The only downside is the bottle is a bit small. I wish it came in bigger volume.

Sans doute, c’est le meilleur soin thermoprotecteur que j’ai utilisé ces dernières années 🔥
J’ai testé de nombreuses marques différentes, mais c’est celui-ci que j’ai préféré.
Tout d’abord, sa texture est très légère. Il n’alourdit absolument pas les cheveux et ne les laisse pas collés entre eux. Après l’utilisation, les cheveux sont incroyablement doux et soyeux au toucher.
J’ai vraiment adoré ce produit et je le rachèterai sans hésiter 😍
