Bain Hydra-Glaze from Kérastase is a hydra-illuminating shampoo for long hair prone to frizz. The formula with hyaluronic acid, glycolic acid and wild rose oil cleanses the scalp, smooths the hair fibre and leaves hair glossy and soft.
Bain Hydra-Glaze is developed for long hair that easily becomes frizzy and needs more shine. The shampoo combines cleansing and care in a formula intended to provide a cleaner scalp and a smoother hair fibre. The goal is hair that feels fresh, soft and more manageable after washing.
The formula contains hyaluronic acid, glycolic acid and wild rose oil. Together they work to moisturise, smooth and give the hair a more polished surface. The gel-like texture foams easily and spreads through wet hair, where it cleans both the scalp and the hair surface.
The result is described as a long-lasting clean feeling, anti-frizz for up to 4 days and shine for up to 4 days after application. The shampoo is particularly suitable when you want to combine everyday cleansing with a more cared-for, glossy appearance.
The foaming, gel-like formula cleanses the scalp and the hair fibre surface without focusing solely on washing. It is designed to give a clean feeling while providing nurturing support to the hair. This makes the shampoo suitable when you want a product that both cleans and improves the hair surface.
Hyaluronic acid contributes moisturising properties, while glycolic acid and wild rose oil are included in a combination intended to help the hair feel softer and more controlled. When the cuticle seals better the surface becomes smoother, which can reduce the appearance of frizz and give a glossier finish.
Bain Hydra-Glaze focuses on the balance often required for glossy hair. Cleanliness, care and the hair fibre structure work together to create a smoother result. This makes the shampoo especially relevant for long hair that easily loses shape or becomes dry at the surface.
According to the product information the shampoo provides anti-frizz for 4 days and shine for 4 days after application. This is a clear advantage if you want your hair to look freshly washed and better cared for for longer between washes. For extra shine it is recommended to use it together with other products from the Gloss Absolu range, such as Insta Glaze.
The scent is described as an unexpected haute couture blend with citrus notes and a luxurious floral bouquet. It gives the washing moment a more sensory feel without overpowering the product's main function, which is to cleanse and care for the hair.
Use the shampoo on wet hair and rinse thoroughly. The formula is gentle enough for daily use on fine or normal hair. This makes the product easy to incorporate into a regular hair care routine, especially if you want a shampoo that combines practical cleansing with a focus on shine and a smoother hair feel.
