Strengthening Conditioning Spray

La Biosthetique Strengthening Conditioning Spray is a premium, professional leave-in spray conditioner specifically formulated to revitalize fine, weak, and limp hair.

It bridges the gap between high-performance haircare and weightless styling, delivering intensive structural reinforcement, hydration, and thermal protection while creating maximum airy volume and flexible hold, all without weighing down delicate strands.

Best for:

• Fine, weak, and limp hair;
• Those looking to revitalize fine hair with weightless care and flexible hold;
• Anyone seeking a pre-styling priming spray that protects against heat damage.

Key Product Pros:

• Rapidly detangles and moisturizes fine hair with zero residue or heavy buildup;
• Plant proteins actively mend structural deficiencies and seal cuticles to reduce split ends and breakage;
• Guards delicate hair fibers against high temperatures and styling heat;
• Visibly pumps up individual strands from the root for a fuller, denser appearance;
• Leaves the hair feeling incredibly soft, bouncy, and elastic with natural, non-stiff hold;
• Completely vegan, silicone-free, and certified cruelty-free.

Active Ingredients:

• Tahitian Microalgae Extract noticeably thickens the hair shaft, strengthens internal bonds, and revitalizes lifeless strands;
• Rice and Soybean Proteins work to balance structural damage and gaps within the hair cortex, enhancing the hair's overall resilience, density, and thickness;
• Carrageenan Moss and Sugar Kelp Extracts form a protective barrier over the cuticle layer to maximize heat protection from dryers and styling tools;
• Provitamin B5 (Panthenol) and Pentylene Glycol bind intensive moisture to the core of the hair fiber, imparting vibrant shine and restoring natural elasticity;
• Polysaccharide Complex (Pullulan, Sorbitol, Trehalose, and Acacia Senegal Gum) wraps the hair to deliver luxurious softness along with a pliable, touchable, and long-lasting light hold.

About Volume Line:

• The line is specifically engineered to target fine hair, which naturally averages a thinner diameter compared to normal hair.
• Because fine hair lacks structural bulk and is highly prone to split ends, breakage, and flat styling, the Volume line leverages clean biotechnology and plant proteins to expand the hair's diameter organically.

Wash your hair, ideally with La Biosthetique Strengthening Shampoo, and gently squeeze out excess water with a towel.

Shake the bottle well and spray evenly into towel-dried hair from roots to ends.

Comb through the hair to ensure seamless distribution across all sections.

Leave the product in and do not rinse out, then blow-dry or style your hair as usual to fully activate the thermal protectants and volumizing microalgae.
