Kareol Brazilian Keratin Straightening Kit - Extra Repairing, Formaldehyde-Free Vegan Formula, Up to 12 Weeks Smoothness

Kareol Extra Repairing Brazilian Keratin Straightening Kit is a formaldehyde-free, vegan at-home keratin system that smooths, repairs and helps straighten hair for salon-style results up to 12 weeks.

This kit combines vegetable-derived keratin with targeted repairing actives to rebuild weakened strands while reducing frizz and improving manageability. Formulated without sulfates, salts, parabens or animal ingredients, the treatment is designed for people with dry, damaged or chemically processed hair who want long-lasting smoothness from home. A flat iron is required to seal the formula and optimize wear time.

How does this keratin kit improve damaged hair?

The formula replenishes structural proteins and adds conditioning actives to reinforce elasticity and reduce breakage. It works by coating and smoothing the hair fiber, which helps hair appear shinier and more uniform in texture without weighing it down.

• Vegetable keratin strengthens cuticle and inner fiber support.
• Repairing actives restore flexibility and reduce snap-off.
• Lightweight conditioning maintains bounce and movement.
• Free from salts and sulfates to protect treated hair.

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

When applied following the included instructions and sealed with a flat iron, most people see smoother, glossier hair that is easier to style and less prone to frizz. Results vary with hair type and prior damage, but the formula is engineered for durable smoothing that can last up to 12 weeks with proper aftercare.

• Soft, shiny finish that improves manageability.
• Reduced styling time due to straighter, sleeker hair.
• Duration up to about 12 weeks depending on maintenance.
• Best longevity when using sulfate-free shampoos afterwards.

How simple is the at-home application and what tools are needed?

The treatment follows five clear steps designed for home use; attention to detail in each step ensures the best outcome. A professional-style flat iron is required to lock in the keratin for lasting smoothness, and heat protection and sectioning tools help achieve even coverage.

• Five-step process with a detailed guide included in the kit.
• Flat iron (high heat) required to seal the treatment.
• Sectioning clips and a fine-tooth comb recommended for precision.
• Use only recommended post-treatment products for maintenance.

Is this safe for color-treated or chemically processed hair?

The vegan, formaldehyde-free formula is formulated to be compatible with color-treated and relaxed hair, offering reparative benefits without harsh salts or sulfates. For best results, perform a strand or patch test and follow the kit instructions carefully, especially on previously processed areas.

• Suitable for color-treated and chemically processed hair when instructions followed.
• Patch test recommended to confirm compatibility.
• Gentle surfactant profile helps protect color vibrancy.
• Avoid mixing with other chemical services during the same appointment.
