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.

Use this if you WANT to have extra fragile damaged doll hair
May 13, 2017
I am a licensed cosmetologist. I have worked in a salon for many years. I figured that I would give this product a shot after it was recommended to me at a local beauty supply store. I thought this would be similar to the Brazilian blow out and wished to apply it on myself as a money saver/time saver. I had followed the instructions to the "t". Sectioned hair, started applying on small partings. Well as I combed the product thru the back two sections to distribute the product, I noticed my hair lacked elasticity and some actually had broken off. This product had only been on maybe 2-4 minutes tops. I RAN AND SHAMPOO-ED MY HAIR. The damage was already done. My hair one week later after using a "hair perfecter" that starts with "o" and a porosity controller, my hair is "nappy" damaged beyond repair, and mushy when wet. Do not use this product unless your hair is Virgin or possibly colored with only demi permanent color! You will be sorry! This item makes your hair smell like an old ladies perm despite rinsing it for 10 minutes. It will melt your hair. Thank you, to the lovely fancy lady at that beauty supply store. May karma get you and your hair breaks off at the scalp. I may have to get a pixie to cut off my damage. To maintamer makers, you are marketing a horrible product to professional hairdressers. I am so angry and disappointed. I will be sure to share my experience with everyone I know!

My aplogies to the manufacturer of the product but the 2nd time I used it, it sizzled my hair so I've lost a significant deal of length. It's been several months since this happen and my hair is not growing in the back where it sizzled, as quickly as I would like it to. If the manufacturer could kindly reply with some kind of explanation or solution to this affect, it would be appreciated ? Thanks

directions must be followed to a T for good results
March 11, 2016
I have used Maintamer 6x over the last 4 years and only once was there breakage and it was completely my fault. The rinsing for 10 minutes after step 1 is a must, but just then our hot water tank broke and water was ice cold so I stopped after 7 minutes. There must be no residue of step1 on the hair when step 2 is applied. Felt a burning sensation the next day, Lost tons of hair. Completely acknowledge my fault. Never a problem again after. Hair grew back and all is well. Do this twice a year, before southern winter vacation and hot muggy summer.
Hair sleeker than I had even hoped for, easy to style and no more frizz

i use this product on my hair two weeks after using permanent dye. . I read all the reviews about people hair being fried and falling out so that made me kind of worried about using it. Because I have had problems with hair loss in the past by using other chemicals in my hair I did not leave the product on for the recommended time because I was afraid of damaging my hair. With that being said my hair turned out great.

July 23, 2015
I am a stylist and have used this product on thick wavy hair and super thick super kinky hair with amazing results. I've read through these reviews and am amazed. I'd definetly recommend going to a distinguished salon AND stylist to have any service done but especially any chemical service. I read on one bad review that the product smells very strong and while I'll agree that it has an odor it shouldn't be so overwhelming or strong. Not only is past services a variable but you also want to make sure any chemicals you put on your hair aren't expired or counterfeit i.e. buy it from a reputable PROFESSIONAL beauty supply

I did not purchase this product myself however I had a stylist a salon use it on me.Its been 3 weeks and my hair has been breaking off and coming out in chucks ever since. The nape of my neck looks like someone took a buzzer to it. Its horrifying. Ive been advised the way to save my hair is to get an Olaplex treatment, use sulfate free shampoo and conditioner and use protien rich products. This service cost me enough to start with. Not only am I losing my hair because of it, im losing all my money trying to fix it. Ugh.
Nope. Nope. Nope.

Awesome, but for professionals ONLY!!
April 8, 2014
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

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.

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 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
Bad smell and a little damaging to hair

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

I use this product about a week prior to getting a Brazilian blowout. It seems to make the blowout last longer. I have also used this product after getting the Keratin straightening treatment at the salon. One word of advice 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
