The brand I bought was One & Only Ionic Thermal Hair Straightner for Highlighted Hair/Color Treated Hair. It's actually made by Jehrri Redding. It is sold to professionals only, but I found it on EBay. I spent $50 total including the kit and supplies for 2 people. We had enough product for three people in one kit.

My sister and I did each other's hair, mine took 3 1/2 hours, chin length. Her's took me only 3 hours, and is shoulder length.
Both of our hair types are very fine, with some highlights, the only difference is mine is curlier than hers.

You cannot shampoo, wet, ponty-tail, or clip, etc. for 48 hours, and are to avoid crimping as well during this time period.

After doing using this process our hair was left smoother and shinier than ever. My hair went from curly to wavy, it is easier to straighten, takes about half the time, but I still have to blow-dry and touch up with a ceramic iron.
I will experiment further in about a month or so, and will update this.

I think I may need a hotter iron, about 230 degrees to obtain pin-straight hair. Or I may need to let the first chemical step process longer. The directions are very good, but not specific on the time limit for processing this step. The package said 7-30 mins processing depending on hair type and knot test, but did not give an absolute max time. I think it's because it's sold for pro use only. I had left the first step in for 35 minutes, no damage.

You will need:

A good quality CERAMIC higher quality straightening iron, they say one that heats to at least 215 - 260 degrees. You need one that maintains constant heat. (I would recommend the higher range for curlier hair.) I have seen tale that irons up to 300 some degrees have been used in this thermal reconditioning process in salons! The steam created from my 215 degree max iron melted one of our combs! Please be careful!

A hightlighting brush.

A shampoo cape

Saran Wrap

A few medium and finer tooth combs.

A shampoo comb.


Flexibility to do a back-bend into the sink, or a shampoo basin. (You want to keep the chemicals off your skin.)

Read the instructions CAREFULLY and follow them.
