Unruly hair
February 21, 2011
I read all these reviews & i'm shocked that people's hair fell out! I've had this done to my hair a few times by a few different professionals & NEVER had any problems like that. I'm wondering if they had previously done some kind of other chemicals or bleach on their hair or they didn't do it right; leaving it on too long, not completely rinsing? My hair is very stubborn & hard to fix & everyone that has ever done anything to my hair has told me it's some of the most difficult hair. I'm 27 & caucasian. I have very frizzy small curls in the front and very wavy thick hair in the back that will not go straight. This doesn't straighten my hair completely, just calms it down alot. It definitely helps though. I can usually get it straight easily with my chi flat iron. The only time I have every had extra straight hair is when i had the chi straightening system done, about 4-6 months later had my roots touched up & it resulted in a permanent wave, so then a week later my hair stylist straightened it again with the maintamer. that was the first time I had had it done. I loved it. However, the maintamer alone will not have the same effect. Still after all that permanent straightening within a short period of time, I had no problems at all with loss of hair or "fried" or damaged hair. If it wasn't so bad for your hair, I'd have the chi & maintamer done together all the time. ;) I was wanting to try this myself with the help of my sister until I read all these reviews, but now i'm not so sure.

Awesome, but for professionals ONLY!!

This is a great product, but for anyone that somehow purchased it on their own and had bad results, it's probably because you aren't a hairdresser and you aren't supposed to be doing it yourself. We are educated on chemicals like this. If you did purchase this, it was probably expired first of all. Someone obtained it and are making money off of you, the company does not sell directly to the consumer. The amount of education it takes to master Relaxers/straighteners is far too extensive for someone with zero training to be able to master just by reading the directions. That goes for haircolor as well. If you want your hair done right, find a reputable hairdresser with training and keep your hair healthy by using professional products. There is a reason we go to school for this.
versatile: can be done bone straight or still keep wave. No damage on healthy hair. beautiful results

My hair is chemically straightened, my hair dresser applied this ISO Maintamer to my hair, 10 days later I colored it with permanent hair color. My hair is falling out by the handfuls. I would not recommend this to anyone with chemically treated hair....DO NOT USE!!!
Chemically treated hair do not use this product. Your hair should be virgin.

I attend a cosmetology school n on student service day I had to use an ISO straightener on my hair and the day I got it my hair was so beautiful that my mom went and got it done on her hair. The next day and I mean the very next day after I comb down my wrap I had piles of hair on my floor and sink. The back of my hair was completely broke off and i can't touch it without it breaking off. I went to school and my instructor, who did the treatment, had no idea what went wrong. She was at a lost when she seen my hair. I tried to contact ISO to see if they can tell me what's going on n I haven't got an response back yet. My mother called me and was screaming and yelling that her hair was falling out in humps and I know that her treatment was done correctly because our campus manager did it because it was the first time someone came in and ask for one. Can anyone help us. My hair was down to he middle of my back and now it barely touch my shoulders and my mom hair is now up to her ears because of the treatment..

Does what it claims but use caution
July 28, 2013
I have used the product a total of 4 times now over the course of 2 years and each time I have lost some hair. Although following instructions to the letter, and rinsing 10 minutes as required after step 1 and 5 after step 2, each time I have lost quite a bit of hair and my hair-colour which is natural not dyed has changed, my hair is lighter, which is not necessarily bad but leaves a regrowth which I don't like. After a few weeks when you touch my hair roots you can feel a regrowth like a toothbrush where the broken hairs are growing back, which means I have 4 different lengths of hair now and lots of flyaways in my very long hair. I am currently researching other options to tame my waves in future as I would like to avoid the hair loss.
Does straighten hair as intended. Treatment lasts several weeks on me and hair has been a lot easier to style, in fact I hardly straighten it now, just allow my hair to dry naturally with a bit of a wave. Hair is silkier after application.

pretty good
July 24, 2013
okay...I was totally freaking out when I read the bad reviews here. I almost chickened out. My stylist talked me into it and so far so good! My hair is naturally curly and very processed. 90% of it is highlighted...so I was really nervous. I had no hair loss...fairly dry but otherwise it was a lot more manageable. It's still a little wavy but way less time straightening. This is something I will probably only do for the summer months when it is humid.
A lot quicker than the other straightening systems

I tried this on my waist length virgin crazy frizzy and newly coarse curly dryyyyy hair. I did a strand test 24 hrs before because of the negative reviews I read. I really love it. The only thing I can say is because I was so scared to surpass the 30min process time only the first side of my hair that I applied the step 1 too. But I really loved the process sides results. No breakage so far. No tangles. Silky. Calmed curls, easy to dry. I blow dried and flat iron Afterwards with a keratin spray . My hair is so thick that it usually looks like I have a poof at the roots. Now this time. I can't wait to wash it and see. I'll right a new review then. Great product. Use a timer n get some1 to do one side while you do the other so you can get equal results. Loved this. I Already ordered another for my 3 month touchup.

Used to Love it --- Use with EXTREME caution!
September 10, 2012
I'd had the Iso Manetamer done to my hair professionally several times with great results. I was able to grow my hair to a length of over 30" to donate to Locks of Love. Last year, after cutting my hair to my shoulders, I had the same professional do my Iso straightening and it FRIED my hair, mostly in the back ... this was strange, no other chemicals were in my hair other than permanent hair color I've used for several years. I had to grow out my hair for a year to cut off all the damage. Yesterday, I decided to give Manetamer another try and applied it at home, following all the directions EXACTLY and used a timer. I even rinsed my hair standing in the shower to insure all chemicals were fully rinsed. RESULTS ARE DISATEROUS! I now have VERY frizzy/puffy hair that is far worse than when I started with relatively straight hair with some random coarseness to it. My hair just tears apart and won’t dry since all the hair bonds have been destroyed. I will be cutting my shoulder length hair into a Pixie tomorrow night ... oh well. The only thing I can think is that the color I use (Satin Hair Color by DeveloPlus) has some ingredient that reacts to the Iso Manetamer. My color used to be done professionally with Paul Mitchell color and I had no problems using the Iso strengthener then. BE CAREFUL using this product IF YOU HAVE ANY OTHER CHEMICALS in your hair, applied by you or a professional. Just trying to save you the heartache of potentially ruining your hair. SKIP ALL THE CHEMICAL STRAIGHTENERS and embody your hair's texture, or use a flat iron.
It used to work GREAT, but has now fried my hair twice.
Should have more warnings on product to professionals and individuals, that have anything but virgin hair, to caution them about potential interactions.

I really don't understand the bad reviews. I am a stylist and we use this in our salon with excellent results. Haven't had anyone complaining of their hair falling out. Clients love it. It makes me wonder what other processes were previously done to their hair to make it fall out. I've done it on myself twice now, and I love it. My hair never frizzes or poofs out anymore. If anything, I notice LESS hair in my shower drain. However, I do recommend having this done by a professional AND to inform the stylist of other things that you have done to your hair previously. Overprocessed hair and then having this treatment put on top of it may be the problem.
Beautiful results.

I had a perm with kinky curls and I waited for three weeks and I decided to color my hair then I go my product in the mail and I waited three days to use ISO and I Knew I was taking a chance in damaging my hair but I did it anyways, very little hair broke off and the color got a little lighter but my hair got straight again. I was so happy about this product and I have recommened alot of my clients to use this product.

Worked the First Time, Ruined my hair the second time
March 10, 2012
I got this done in a salon and absolutely loved it! I have curly hair that easily frizzes up and I was so afraid that this product would make my hair pin straight and lifeless. I was so happy with the results. It was my own hair, but with no frizz. I would wear my hair in a pony tail without worrying about the side curls popping out. As soon as I noticed this starting to wear off (I starting noticing some frizz at the roots), I made an appointment to get it done again, and the second time ruined my hair. The ends of my hair are so dry and damaged. I had the second treatment done in September, and have had countless cuts since then (about an inch every 4 weeks), and my ends are still so dead and dry looking. And, it did something strange to my hair at the roots. Instead of lying down, the shorter hairs around my face kind of just stuck out to the side, and I have to use a straightening iron to get them to lay down. I am totally not happy at all. It is now March and the effects are still with me. I am eager to try something else with summer coming, but I will not be trying this product again.

Wonderful relaxer.
February 10, 2012
I first experienced Maintamer when my hairdresser suggested it to straighten my intensely curly hair for a short bob. I loved it right away. It straightened my hair and looked natural and didn't leave too much damage, even after touch-ups. Unfortunately, my hairdresser moved and I couldn't find another who used this product. Desperate for the same results I looked online and decided to try it myself. I'm not a professional so I did leave it on too long in some spots leading to damage. However not enough to discontinue using the product. I'm not a professional and I've used it on myself at least four times with great results and will continue to. If you are going to use this product on yourself, make sure to follow the directions exactly. Do not start application right at the scalp, and keep a timer on hand. Its better to leave it less straightened than desired and go back for light touch-ups with left over product, than to over process your hair. I've done light touch-ups with leftover from the same application with great results. Now I get it right the first time and I love this product and what it does for my hair.

Effective Straightener
January 6, 2012
I have used this product for over three years and have had great results each time. My hair is course, thick and frizzy. My first few times I straightened my hair using this product was in a salon, but decided to save the extra money and I now do it at home with help from my husband (he's gotten quite good at it). Just make sure to wait at least two weeks after straightening to have any other process done, or you will damage your hair.

I get this done in a salon every 3 months, it is really expensive where i get it done so I was thinking of just buying it and saving $80. It smells a lot like a perm but it straightens and smoothes hair. It doesn't dry out your hair or make it fall out like people have said. I like it because it smoothes and straightens without damaging your hair and its not that hard to do. I'm not sure why people have said their hair falls out but the might be putting it on their scalp because you're supposed to keep it about 2-3 inches away from your scalp so yeah, but I think it works amazing!

I have had this done in a salon twice and both times it was a dream come true. Silky straight hair with no frizz. I have very, very thick, course hair and this leaves my hair shiny and frizz free. You still have to blow your hair dry as with any straightener, but it cuts the time in half. This time, I did it myself and it cost me $19!!!! It came out great! For some reason, it didn't change the color of my hair too much this time. Sometimes it lightens your hair. Anyhoo, I LOVE this product and will be applying it myself from now on. It was a cinch. I see here it's $12????? BINGO!!!

Does anybody have the ingredients for this? I just purchased this and can somebody go into more detail and provide any extra tips on using this? I want to get it right the first time!
By Tinamarie from Florida on December 14, 2011

The first time I used this product was from a hairdresser. She charged me 80.00 to do my hair. When I found out how much the product cost, you can only imagine how mad I was that she charged me so much. Since then I have purchased it on my own and have used this product when my hair starts to grow out. I don't know what is in the product, but it does not burn and it does not hurt the hair and it works. Make sure you wash your hair first, leave it wet without a conditioner in it. I usually put it in a small bowl so it is easier to put the comb in the product and work through the hair. Use different clips to separate your hair and comb through each section. You must leave it in for 15 min. But make sure if you have a part that you part it the same way because it will straighten your hair the way you put it on your head. After 15 min. rinse the product and make sure you get it all out. Again don't use conditioner. The tube marked number 2 is the conditioner and a neutralizer. Again put it throughout your hair like you did the first time and leave in for 15 min. Rinse it out and feel how silky your hair is. Great product and I use it all the time for regrowth of new hair. It is a great product, never had any breakage nor does it burn your hair. I love this product because it not only straightens, but it still leaves my hair with some body. Good luck and follow the directions for use and you won't go wrong. My hair is very curly and I don't get anymore frizz in the humid weather here in Florida nor does it frizz in the rain. I will be ordering it again very soon from Sleekhair.com.

I use this product about a week prior to getting a Brazilian blowout. It seems to make the blowout last longer.

One word of advice though....do watch your timing and don't leave it in your hair for a minute longer than what is recommended.

My daughter and I have used the main tamer we both have done it 3 times total , she just had it done last weekend at Capri beauty school/ she had done the first 2 times at one location and this most resent one at another location. my question is that the 2nd location did the process totally different from the 1st. they put the tamer on her dry hair didn't use a clarifing shampoo/ didn't comb it thru 1/4 off her scalp but rubbed it on to her scalp which burned she the tech said it's just like a perm it 's going to burn. They didnt flat iron like the first they only used the blow dryer on a cool setting. and the very next day her started breaking off pretty bad. So which way is correct and what can she do to stopp the breakage or at least minimize it

First shampoo your hair with iso clarifier shampoo twice.....no conditioner just clarifier shampoo...towel dry yor hair......apply step 1........ 2 inch away from scalp thru the ends use wide tooth comb.....keep 20 to 25 min make sure it doesnt touch your scalp ......after 25 min rinse....really well at least for 10 min........towel dry your hair again...and apply step 2.......step 2 is faster just keep that for 5 min. ......rinse that at least for 5 min..
Dont shampoo your hair........just a little bit of iso conditioner......towel dry your hair and apply ISO foam and blow dry your hair.......it works great.....this treatment is good for virgin hair.....or hair that never use a higher developer ......
