KeratinPerfect 30-Day Brazilian Hair Smoothing System Essentials Collection

What it is: A complete solution for achieving perfectly smooth, healthy, frizz-free hair at home.What it does:The Essentials Collection contains everything you need for two full smoothing treatments, along with aftercare, including PerfectCleanse Keratin Enhanced Shampoo, PerfectSilk Keratin Enhanced Conditioner, and PerfectRenew Daily Keratin Replenishing Spray. 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. 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 Treatment- 3.4 oz PerfectCleanse Keratin Enhanced Shampoo- 3.4 oz PerfectSilk Keratin Enhanced Conditioner- 3.4 oz PerfectRenew Daily Keratin Replenishing SprayWhat 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 features exclusive ReBonding Technology, which 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. These products contain 40% natural keratin and silk collagen proteins.The KeratinPerfect system is a long-lasting, salon-quality smoothing system, and 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 and will be smooth, shiny, manageable, and frizz-free without a lot of time and effort.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.

Questions & Answers for KeratinPerfect 30-Day Brazilian Hair Smoothing System Essentials Collection

Question
Can I use my own ceramic iron with the treatment?
I have a ceramic iron (CHI) so I'm wondering if it's ok to use this instead of the titanium flat iron.
I don't need two irons and my ceramic one works quite well up to now.

answer 2
I have a CHI ceramic, too. If yours gets up to the right temp, it should be fine, mine didn't. The sales associate at the Sephora I went to suggested a titanium iron to retain heat better. It was only a suggestion she wasn't forcing me to do it but she did emphasize the temperature was very important.

If you look at the KeratinPerfect instructions insert it doesn't specify the type of flat-iron, only that it MUST be at a certain temperature to bond i.e. 380 to 410 degrees for damaged hair, 410-430 for processed hair, 430 to 450 for coarse or "virgin" hair. I had to look up my model number on the internet, but found out my CHI did not get up to the temp it needed to be for my hair, so I bought a cheap-o ceramic one that did. Worked out fine! I think a lot of bad reviews out there is that people are not getting the right temp (too cool won't bond and you'll waste your time and money, too hot and it will damage your hair) Follow the directions, you'll be fine.

Yes - you can use your own flat iron as long as it reaches the correct temperature for your hair type. My Chi goes to 410 degrees and worked fine.

Shampoo and conditioner is included in this kit. You are also provided with 2.5 oz of PerfectPrep Pre-treatment clarifying shampoo. I recommend that you use only the shampoo provided in the kit, especially the clarifying shampoo because it is designed the really clean your hair, which is necessary for the product to work properly.

It needs to be sulfate free. I know some people use bed head superstar & organix. The shampoo and conditioner that comes with works great though!

answer 5
The package insert suggests you use their brand, but that if you want to use your own, make sure it doesn't have Sodium Chloride or Sulfates in it that will strip the keratin off. I did get the kit with samples of their shampoo and conditioner and their stuff works great, but I do like to freedom of using my own favorites as well. I've used my home shampoo a few times (I use Phyto and Ojon most days). Hair looks great, and I'm going on week 3. You can always go into a Sephora and ask for samples of the Karatinperfect shampoo and conditioner line to see if you like it, otherwise read your own brand's ingredients list.

This product (for me at least) only lasted about two weeks. It did not straighten, soften, or de-frizz my hair to any noticeable degree. Definitely not worth the price or time.

answer 2
Not nearly as long as a brazilian, it lasts about two weeks real good and then it starts to fade a bit. Its about 3-weeks at the longest - but it does give you enough for more than one treatment. You should have enough for two or three months depending on your hair type & how much you wash your hair.

I would think so. It makes your hair really healthy, and just provides it with keratin not like relaxer chemicals or anything. It will also protect it from getting any further damaged. It deff. makes your hair softy & shiney too, so you will probably find your hair to look a lot nicer.

AROUND 2 POSSIBLY FOR SHORT HAIR 3

answer 4
Short, ear-length hair will need 1 to 1.5 ounces.
Shoulder-length hair will need 1.5 to 2 ounces.
Very long or coarse hair (hair that goes below bra length) will need 2 to 2.5 ounces.

These amounts are directly from the treatment instructions. This means that, since the smoothing treatment bottle contains 5 ounces, you should atleast get 2 treatments worth if you have very long or course hair and more for shorter hair as long as you don't run out of the shampoo.

"KeratinPerfect works with your hair’s natural texture to produce a smooth, healthy result. Ultracurly hair will become smoother, while naturally straight hair will appear healthier and shinier. Extremely coarse hair types will not become completely straight, but will see a reduction in frizz and curl. All hair types will be more manageable and easier to style after treatment."

They suggest doing any color treatments before the keratin treatment because it will help to lock in the color and actually protect it.

safe after Brazilian Zero blowout and highlights
One month ago I got the new Brazilian Zero Blowout that doesn't have formaldyde, but my hair is still frizzy. Now I got highlights and it's really frizzy. If I use this product now is it too much keratin? Will it cause my hair to break if I do it now or will it make it less frizzy and healthier looking?
