1. Permanence.
Japanese Thermal reconditioning (e.g., Yuko) is permanent. In other words, the hair stays straight until it grows out. Most people, depending on the length of their hair, will repeat the procedure between 9-12 months.
The Brazilian blowout is a temporary treatment that lasts between 8-12 weeks.
2. Toxicity
Yuko uses FDA approved chemicals which are non-toxic and not carcinogenic. For example, Yuko incorporates the same chemicals as used in permanent waves.
Keratin treatments (such as the Brazilian Blowout) use chemicals such as aldehydes (which used to include Formaldehyde but now includes other aldehyde chemicals), which can cause eye irritation and burning of the throat and nasal cavity. In fact, manufacturer recommendations include ventilation systems within the salon, plus safety masks worn by stylists. The Environmental Protection Agency (EPA) has determined that formaldehyde is likely a human carcinogen based on limited evidence in humans and sufficient evidence in laboratory animals.
3. Patented Process
The Yuko Hair Straightening System obtained patent approval in the United States in 2000. It was approved as a "Hair Repair, Styling and Straightening Process" and is also a recognized technique of restoring health to the hair. The world-renowned researchers of Phi-ten first developed the breakthrough technology of water-soluble gold, "Aqua Gold." This special water undergoes what Phi-ten call the "Phild Process" and is made electrically stable, which in turn allows for active ingredients in hair solutions to permeate the hair swiftly, minimizing damage from chemicals while producing the desired effect. All YUKO products use soluble gold to bring to your hair the perfect harmony between exquisite beauty and vibrant health.
4. Wait Time
After the permanent straightening process you must wait 72 hours before getting your hair wet.
With the temporary straightening you can wash your hair immediately if desired.
5. Cost
Pricing can vary from $200-$400 for each temporary (keratin) treatment and from $400-$600 for the permanent straightening.
6. Additional (Hidden) Costs
With Japanese thermal reconditioning, no specific product (shampoo and conditioner) is required. Providers of the Brazilian blowout will not guarantee results without the use of their specific products (shampoo and conditioner).
7. Processing Time
Treatment time varies between 2-3 hours for the temporary (keratin) treatment to around 4 hours for the permanent system.
Another factor that may affect which process you choose is related to whether or not there are salons in your area that offer these types of treatments. Check your local listings online to find a reputable salon in your area, and be sure to make an educated decision based on factors such as length of experience, stylist qualifications, and satisfaction guarantee (as opposed to merely choosing a salon based on price).
