Prohall Cosmetic Brazilian Keratin Treatment 4.05 oz — Formaldehyde-Free Smoothing & Shine

Prohall Select One is a professional-grade, formaldehyde-free Brazilian keratin treatment in a 4.05 oz formula that reduces frizz and volume to deliver smoother, shinier, more manageable hair.

Hailing from Brazil, Prohall Select One combines keratin, collagen, coconut oil and modern nanoplastia/Lumini system technology in a compact at-home treatment. It’s formulated to straighten, nourish and strengthen hair fibers without formaldehyde, offering salon-style results with fewer harsh chemicals. The 4.05 oz size is ideal for single-use or trialing the product before committing to larger kits.

How does Prohall Select One change frizzy or unruly hair?

The formula works by coating and temporarily realigning hair fibers with keratin and restorative agents, which smooth cuticles and reduce static. Over repeated use the hair looks sleeker and behaves more predictably in humid or dry conditions.

• Keratin + collagen rebuild surface strength and elasticity.
• Coconut oil adds moisture and luminous shine.
• Nanoplastia/Lumini system helps seal the cuticle for longer-lasting smoothness.
• Formaldehyde-free composition reduces exposure to harsh fumes during application.

What results can I expect and how long do they last?

Expect visibly reduced frizz, lowered volume, and a silkier texture after a single application. Results vary by hair type and aftercare, but many users report smoother, more manageable hair for up to several months under proper maintenance.

• Immediate smoothing effect once the hair is processed and flat-ironed.
• Enhanced shine and reduced breakage from strengthened fibers.
• Longevity depends on washing frequency, shampoos used, and heat styling routine.
• Ideal maintenance: sulfate-free shampoos and limiting clarifying treatments.

How do I apply this at home safely and effectively?

Follow the included instructions and perform a patch/strand test before full application. Work in a well-ventilated area, section hair for even coverage, process for the recommended time, then rinse, dry, and flat-iron to lock the treatment in.

• Section hair into thin layers for consistent product distribution.
• Process times vary by hair porosity—consult product directions for guidance.
• Use a ceramic flat iron at the advised temperature to seal the keratin layer.
• Rinse and avoid harsh sulfates for best longevity.

Will this treatment work on all hair types, including color-treated hair?

Prohall Select One is formulated to be compatible with a wide range of hair textures, from fine to coarse, and can be used on color-treated hair. Because every head of hair is different, consider a strand test if hair has extensive chemical history or is highly porous.

• Safe for color-treated hair when following manufacturer recommendations.
• Gentle formula suitable for fine, medium and thick textures.
• Strand test advised for bleached or chemically sensitized hair.
• Adjust processing time for very porous or very damaged hair.
