Prohall Cosmetic Brazilian Keratin Treatment Select One 4.05 oz — Formaldehyde-Free Smoothing, Long-Lasting Shine

Prohall Select One is a professional-grade, formaldehyde-free Brazilian keratin hair treatment that smooths frizz, reduces volume, and restores shine for up to six months.

Made in Brazil and formulated for at-home or salon use, this 4.05 oz Select One keratin complex blends collagen, coconut oil, lactic acid and advanced nanoplastia (Lumini System) technology to nourish and realign hair fibers without harsh formaldehyde. It’s designed to deliver straighter, more manageable hair while repairing and hydrating strands, suitable for all hair types from wavy to very curly.

How quickly will I see smoother, less frizzy hair?

Visible smoothing begins immediately after application and rinsing; final sleekness appears after blow-drying and flat-ironing. Results depend on hair porosity and texture, but many users notice reduced frizz and easier styling after the first use.

• Initial smoothing visible post-rinse and blow-dry
• Optimal straightening achieved after flat-iron step
• Improvement in manageability and shine from first application
• Durability up to six months with proper aftercare

Is this keratin treatment safe for colored or chemically treated hair?

Yes—Select One is formulated without formaldehyde, making it gentler than many traditional smoothing systems. The collagen and lactic acid components help mend and hydrate processed hair, while coconut oil restores softness and sheen.

• Formaldehyde-free formula safer for color-treated strands
• Collagen and lactic acid support fiber repair and elasticity
• Coconut oil reduces dryness and adds shine
• Suitable for multiple hair textures and chemical histories

What is the application process and how long does it last?

Application follows a standard keratin blowout routine: wash, apply the Select One cream mask, process per instructions, rinse, blow-dry, and seal with a flat iron. When used correctly and maintained with sulfate-free care, results can remain for several months.

• Stepwise routine: cleanse → apply → process → rinse → blow-dry → flat-iron
• Processing times vary by hair type—follow included directions
• Use sulfate-free shampoos to extend treatment life
• Touch-ups possible for new growth as hair grows out

Which hair types get the best results with Select One?

Select One was developed to perform across a wide range of hair textures—from fine waves to tight curls—offering frizz control, volume reduction, and enhanced shine. It’s particularly useful for anyone seeking long-lasting manageability without harsh chemicals.

• Effective on straight, wavy, curly, and coily hair
• Helps thick, voluminous hair become smoother and lighter
• Assists dry or damaged strands with reparative ingredients
