Prohall Select One – Keratin Collagen Treatment – 1L

For clients whose hair is weakened by bleach, colour and heat, smoothing has to start with repair. Prohall Select One is a 1 L professional keratin collagen treatment that rebuilds strength from within and calms frizz, while the hair keeps its natural movement — reconstruction-based smoothing instead of an aggressive straightener.

How Select One Works

Hydrolyzed collagen brings back elasticity and resilience to weakened fibres. Lactic acid works through the cuticle to drive hydration and luminosity, and coconut oil seals the surface, settling unruly strands and locking moisture in. Together with the Lumini System, they form a medium-to-strong protective film with a moderate smoothing effect: silky, polished hair that still looks natural.

Results Your Clients Will See

• Restored elasticity — weakened, over-processed fibres become more resilient
• Frizz control with movement — flyaways settle, the hair still moves naturally
• Sealed cuticle — moisture and shine last longer
• Repair — helps undo damage from chemical services, heat styling and environmental stress
• Protective film — smoother, more manageable strands
• Softness — a polished, healthy-looking finish

Who It Is For

Suitable for all hair types and especially effective on damaged, bleached, fragile or chemically treated hair. A good fit for a reconstruction routine when the hair needs both repair and controlled smoothing. For licensed salon professionals only.

Frequently Asked Questions

What does Prohall Select One do?
It reconstructs and smooths in one service: strength comes back to damaged or chemically treated hair, frizz is controlled, and natural movement is kept — no stiff, fully straight result.

How long does it last?
Around 5 to 6 months.

How is it different from Select Blond?
Select One is for all hair types; Select Blond adds a purple pigment to neutralize yellow tones on blonde hair.
