Perfect Treatment Smoothing Duo


Perfect Treatment Smoothing Duo

What it is: The ultimate at-home, style-perfecting treatment that makes hair shinier, smoother, and more manageable for up to 30 days.What it does: The Duo Pack contains everything you need for two full smoothing treatments: full sizes of PerfectPrep Pre-Treatment Clarifying Shampoo and ThePerfector 30-Day Hair Smoothing Treatment. The 30-Day Brazilian Hair Smoothing System is an ultra-smoothing and nourishing treatment that makes blow-drying and styling easier by adding incredible smoothness, shine, and volume. The exclusive KeratinPerfect ReBonding Technology works to transform rough, damaged texture, and repair weak keratin bonds, completely redesigning hair's texture and appearance. This targeted delivery system binds keratin to the cuticle and fills in the rough, dry crevices that can make all hair types appear frizzy, dull, and lifeless. The protective seal locks in moisture while repelling humidity, UV rays, and pollution for up to 30 days. The KeratinPerfect system is not a straightening treatment that breaks the hair's bonds and causes damage. In fact, the benefits of this system are cumulative: Your hair will only continue to improve with each treatment. It's the ultimate antiager for all hair types!This set contains:- 2.5 oz PerfectPrep Pre-Treatment Clarifying Shampoo- 5 oz ThePerfector 30-Day Hair Smoothing TreatmentWhat else you need to know: Keratin, a natural protein found in healthy hair, is constantly depleted due to heat styling and environmental damage. This can cause frizz, breakage, and dullness. KeratinPerfect's exclusive ReBonding Technology fills in rough spots and replenishes lost keratin, replacing frizzy, uneven texture with a protective shield around the hair shaft that radiates shine and health. The KeratinPerfect all-inclusive hair system is a smoothing treatment and care regimen that transforms the hair's overall texture and appearance. The KeratinPerfect regimen reverses damage and nourishes dehydrated strands with natural keratin and silk collagen proteins to reveal your hair's ultimate smoothness, softness, and shine. Whether your hair is coarse, damaged, thirsty, or just needs a smoothing boost, our specialized formulas make it healthier and stronger.KeratinPerfect does not include formaldehyde as a formulating ingredient. Rigorous tests were conducted by the company to ensure that the KeratinPerfect products meet and/or exceed cosmetic formulating guidelines.

Yes. However, I would recommend that the flatiron you use be of good qualtiy and that it has actual temperature settings because the directions have specific heat temperatures listed based on your hair type.

They recommend coloring your hair first and then doing this process right after. It's supposed to seal the color in better.

answer 2
I normally have very curly/frizzy hair. My curls are still there, but definitely not the same and don't form as well. It's been easier to just straighten it than to try and make it look good curly. But this is the reason I wanted to do it in the first place anyway.

You can go on youtube and watch peopel actually do their hair with it step by step. I am not convinced that this stuff is magic and I havent tried it yet, but I want to. Its just Ive been waisting money on hair products containing keratin for years.

According to the directions for use, a flatiron is required. It's the finishing step that seals the treatment. The directions even have specific heat levels listed for your flatiron based on your hair type.
