Love It!
I have color treated hair (permanent hair color) that has to be "touched up" about every four weeks. My haircolor of choice is Copper Red, and my normal haircolor would now be dark brown and gray, or salt and pepper (heavy on the salt). I've had thermal straightening done twice before at a salon, and the fumes were outrageous. I had my friend (who is a hairdresser) put this on my hair, and it turned out really fabulous. This is not something you can do by yourself. You will need assistance, even if your hair is not long like mine. I didn't like the salon straightening treatments because it literally made my hair look like someone had poured oil on it, just too straight. This treatment is not quite so severe which is perfect for my type of hair. I would recommend this product to anyone with fuzzy hair.

NOT formaldehyde free as shown
I was so excited to see this product was formaldehyde free, but when I received it, the box did not say formaldehyde free as shown in the picture. I wasted my time and did not get to do my hair in time for my vacation. Did not have time to order from somewhere else. Contacted sleekhair and they do not have the formaldehyde free version so they couldn't do anything but allow me to return the product (they did provide a pre paid label). Therefore, did not get my hair done in time for my vacation and now I have to waste my time to package and ship it back which I HATE to do.

I did this on my moms hair about a week ago and so far so good, she really likes it! She had sgraight and curly hair and this helped straighten the curly kinky hair. I did not leave it on anywhere close to the max processing times and you do get a lot of product with this so no need to buy more than one box unless you're doing like a whole family with really long hair or something lol. This has the same ingredient as a perm and sure smells like it.

Color Treated Formula - Quantum Thermal Straightner Permanent Hair Straightening
This product6 works great, if you go to a salon that does this it will cost between three and four hundred dollars, I ordered the product and took it to my hair dresser and she applied for me. I ended up with cost of product and putting it on at only $90, the process is time consuming about three and a half hours, but it works so great and when you straighten your hair it looks like it grew a couple of inches over night. I am loving it, so easy to care for just be sure you don't wash for 48 hours and no outside work that will make you sweat. It is an amazing product, but I can't imagine doing it by ytour self. Highly Recommended!

Exactly what I wanted!
I just did my second treatment of the Quantum Thermal Straightener after a year. I've done it by myself both times, which I would not recommend doing because applying step one can take awhile to finish and mess with your processing time. I timed myself as I went and ended up rinsing section by section, minutes apart to make sure everything was processed. Both gave me amazing results, and my hair feels healthier than before. Anyone saying it doesn't work maybe didn't read the directions fully and skipped the flat iron step or didn't saturate the hair enough. And those with breakage probably left step 1 in much too long. Great product, and I would recommend to anyone who wants pin straight hair
Prosno breakage, makes hair feel softer, gets rid of nearly all frizz, very low cost compared to having done at a salon, completely straightens tight curls

Best Hair Week Ever!
I am mixed race (I have fine, thick,medium length, previously curly, colored hair), and have tried many methods to manage or straighten my hair. Although apprehensive, I tried this product based on other reviews, and after 2 weeks I am still in love! My hair has never been this smooth, soft or manageable, and for the first time in my life, I can wash and blowdry my hair in under 20 mins (it used to take me an hour and my hair would still be damp). If you love your curls and don't want to lose them, this isn't the product for you, but if you want straight hair, I would recommend this in a heartbeat over traditional lye and no-lye perms. It took me about 3½ hours from start to finish with someone helping me apply it evenly, but I am absolutely thrilled, and it's so worth the wait. I only used about a third of the package, which is great as I won't have to re-order for touch ups. I recommend the color treated for fine hair, even if you don't have colour treated hair.

Can i dye my hair while this product is already in my hair?
You should wait at least 2 weeks before you color your hair, you could seriously damage your hair if you double process it.

My question is in regards to step 2. My current hair dresser uses a special flat iron to de ionize my hair, after that she applies another solution to lock/neutralize the straightness. Does this product come with the straightener? or how does step 2 compare to my hair dressers straightener? I am fairly confident my hair dresser is using the same brand of product, so if she is I am switching! I just wanted to confirm the straightener part though.

is this for african american hairi
African American Hair has a coarse texture, and the hair fibers are more tight. This product would be better for someone that has a finer texture of hair.

from two and a half to three months, it is an absolutely wonderful product. My daughter has been doing it for years at a salon and paying four hundred dollars, I bought this on line and get my hair dresser to do it for sixty. Such a great deal and a great product, I have colored my hair for years and was amazed at how solf and silky my hair was when it was completed, I was expecting it to be very dry and brittle but it wasn't wonderful product
