About Select One
Prohall Select One is a keratin collagen treatment built for damaged, bleached, fragile, and chemically treated hair. Unlike aggressive straighteners, it focuses on reconstruction-based smoothing: rebuilding strength from within while preserving natural movement. The collagen-rich formula and Lumini System work together to repair the effects of chemical services, heat, and environmental stress, leaving strands smoother, softer, and more disciplined without sacrificing the hair’s healthy, natural finish.
At the core, hydrolyzed collagen restores elasticity and resilience to weakened fibres, while lactic acid penetrates the cuticle to drive hydration and luminosity. Coconut oil seals the surface, taming unruly strands and locking in moisture. Together they form a medium-to-strong protective film with a moderate smoothing effect, giving hair a silky, polished feel and a healthy, controlled finish.

How to use
Wash the hair one to two times with a clarifying shampoo to remove buildup and prepare it for treatment.
Blow-dry thoroughly until the hair is almost completely dry.
Apply Select One evenly, ensuring full coverage of each strand while avoiding the roots.
Let the product process for 1 to 2 hours so it can penetrate the hair structure; timing depends on porosity and texture.
Rinse thoroughly to remove all product.
Apply heat protection to shield the hair during the sealing process.
Blow-dry the hair 100% until fully dry.
Seal the treatment with a flat iron at the appropriate temperature, adjusted to the hair’s level of damage.
