Prohall Cosmetic Brazilian Keratin Hair Treatment 4.05 oz — Formaldehyde-Free, Frizz-Reducing, Collagen & Coconut Oil

Prohall Cosmetic Select One Brazilian Keratin Blowout is a formaldehyde-free at-home keratin treatment that reduces frizz, smooths hair, and delivers salon-style shine and manageability.

This concentrated 4.05 oz keratin complex was formulated to bring professional-grade straightening and deep nourishment into your home routine without harsh formaldehyde. Infused with collagen, coconut oil, lactic acid and the Lumini system, the Select One formula targets frizz and volume while improving hair strength and surface smoothness. It works across textures and densities, offering long-lasting results when applied according to the instructions.

How does this keratin treatment improve frizz and manageability?

The Select One formula smooths the hair cuticle and deposits keratin proteins to reduce flyaways and bulk. By combining humectants and lipids it restores surface softness so strands lie flatter and feel silkier to the touch.

• Keratin proteins fill gaps in the hair fiber to minimize frizz.
• Coconut oil adds slip and shine for easier combing.
• Lactic acid helps align cuticles for a smoother surface.
• Results can last weeks to months with proper aftercare.

Is this safe for all hair types and color-treated hair?

This product is designed to be gentle enough for most hair types, from fine to coarse, and compatible with colored or chemically treated hair when applied correctly. It avoids formaldehyde, making it a milder option compared with traditional straightening systems, though patch and strand tests remain recommended.

• Formaldehyde-free formulation to reduce harsh chemical exposure.
• Suitable for natural, colored, highlighted, or relaxed hair.
• Use a strand test to confirm results and processing time for your hair.
• Follow temperature and timing guidance for best safety and effect.

What results and longevity can I expect from a single application?

Expect visibly reduced frizz, enhanced shine, and smoother texture after one treatment. Longevity depends on hair porosity, washing frequency, and post-treatment care; many users notice improvement lasting several weeks to a few months.

• Immediate smoothing and improved combability after treatment.
• Shine and softness increase from collagen and oils.
• Duration varies—up to several months with low-sulfate aftercare.
• Periodic touch-ups recommended to maintain the effect.

How do I use Select One at home for the safest, best outcome?

Preparation and precise timing are key: start with clean, residue-free hair, apply an even amount of product, and follow the recommended heat and rinse steps. When in doubt, follow included instructions or consult a professional for first-time application.

• Shampoo with a clarifying or residue-free cleanser first.
• Apply evenly, comb through, and leave for the suggested processing time.
• Blow-dry smooth, then flat-iron in small sections as directed.
• Use sulfate-free maintenance products to prolong results.

Who is this for? Prohall Cosmetic Select One Brazilian Keratin Blowout is aimed at anyone seeking a formaldehyde-free alternative to salon straightening—people with naturally frizzy, voluminous, or textured hair who want smoother, more manageable strands without permanent chemical restructuring. It’s also appropriate for those who color or treat their hair but prefer a gentler smoothing system. If you’re new to keratin treatments, consider a professional consultation for first-time application and always perform a patch test to ensure compatibility.
