I just tried this about... 3 hours ago!
I recently switched to shampoos and conditioners that are sulfate free, and I noticed a dramatic improvement in the way my hair felt after shampooing...when previously it would be a disaster and a half every time I tried to detangle on wash days.
I'll describe the process and I'll share my thoughts on it:
1) You first wash your hair with the "de-frizz shampoo". You do not use conditioner. The shampoo smells pretty good.
2) You towel dry your hair (gently, of course) and then apply the formula. (I allowed it to air dry a little bit before applying.) You are supposed to separate your hair into sections and saturate it with the formula... it comes in a spray bottle and there is more than enough. I am almost at MBL and I didn't even use all the formula.
3) The hard part - you must comb the formula through the hair. This took me about an hour...
but I've never been able to detangle my hair any faster, so I'm not surprised. I honestly had a really rough time and almost gave up at this point because it was hard to get a comb or brush through my hair. I found that if you comb your hair as you saturate it with the formula, it's much easier. Finally, I combed it through all the way.
4) Let sit for a half hour... easy!
5) Blow dry the hair straight. I am terrible at this, so I did my best. You are supposed to blow dry until it is 100% dry. I did this.
6) Flat iron all of your hair on a high temperature setting. I used my brush to straighten my hair further... at this point it started to smell bad though. There were no "fumes", just a lame smell from the product.
My hair is very straight right now; you are supposed to go 48 hours without washing, but I plan on leaving it for 3 or 4 days. I'll update everyone when I wash to see if the results are worth the price. So far, so good though! My hair definitely feels nicer.
