Frizz-Free Living: The Top Hair Straightening Methods Ranked

Look Good / Beauty

Kiss your curls goodbye.


With the intense heat of summer looming upon us, our hair is getting frizzier and our willpower to fight it on a daily basis is dwindling. But before you go spend an arm and a leg on a snazzy new set of locks, check out our hair straightening treatment rankings for the best investment possible for your luscious locks.


5. Flat Iron

Okay, so this isn’t really a straightening treatment, but for beginners, a flat iron is the easiest way to tame frizzy hair until your next shampoo. When straightening your hair, make sure it’s completely dry before using a flat iron to avoid further damage to your hair. As straightening hair can make hair dry and brittle, be sure to always use a heat-protecting spray and try to go heat-free on days when you don’t need a straightener.

4. Hair Rebonding

Rebonding is a chemical hair treatment that makes hair straight, shiny and sleek. Hair rebonding involves using a cream or relaxant softener to break the natural hair structure followed by a neutralizer to re-bond the structure again. Rebonding is ideal for those who have problems taming their wavy or thick hair, however once hair starts to grow in, the treatment can be easily detected. As popular as rebonding is, it can only be done every once in a while as it can make hair very fragile and weak. It also requires a lot of hair care maintenance – so choose this one wisely!

3. Chemical Straightening (Hair Relaxing)

Chemical straightening, or hair relaxing, is the process of breaking protein bonds in the hair. When a certain number of bonds are broken in curly or wavy hair, it then becomes straight. However, as simple as that sounds, the execution of it by a professional is crucial for its success. For example, if too many bonds are broken your hair will go limp and if not enough are broken then the hair doesn’t straighten out. This hair care procedure is no joke. However, for those willing to fish out the money for a quality treatment at a quality hair salon, the results are well worth the money…just make sure to do your research first!

2. Japanese Straightening (Thermal Reconditioning)

Using both chemicals and heat, Japanese straightening is a smoothing and conditioning treatment that promotes a permanently altered structure of hair. During a Japanese straightening treatment, protein bonds in the hair are loosened and then reshaped by hair cells. For those of you who can’t sit still, be forewarned this is a lengthy process that involves numerous steps… six to eight hours to be exact. After a few days, you will also need to return to the salon for an hour or so for the final step. On the plus side, this treatment lasts about six to seven months. As amazing and long-lasting as this treatment sounds, it can be very damaging to hair in the long run, so make sure to think long and hard about this one.

1. Keratin Treatment (Brazilian Straightening)

Keratin treatments have become increasingly popular over the past few years, and with good reason. They are one of the safer hair straightening techniques out there. Keratin is a natural protein that is already found in our hair, however as protein content decreases with age and a poor diet, so do keratin levels. The keratin treatment adds a coating of keratin onto the hair shaft giving it nutrients that leave hair silky, smooth and straight.

After a salon professional applies keratin solution to hair, a 450 degree flat iron is used to seal in the formula to hair strands (protect your ears from the heat, ladies), creating a moisture barrier that reduces frizz and gives hair a shiny finish.

The best part about a keratin treatment is that hair grows back into its original structure gradually and the treatment can be done repeatedly without worrying about damaging hair. In fact, keratin treatments actually give better results on repeated usage. While it’s not the cheapest treatment, it will last about six months, especially if you follow the treatment with keratin-infused sulfate free shampoos and conditioners! Tempting, right?


We know that everyone’s hair is different, therefore while our rankings are based on how safe and effective the treatments will be, each person may have completely different results. For best results, be sure to talk to a hair care professional before embarking on a permanent straightening adventure!

    I find the best way to straighten your hair is using natural methods.

  2. Great information. Thanks for the wonderful article, it may be very helpful for everyone who is conscious about.

  3. Nicola says:

    I have just had the L’Oréal straightening treatment , overall I am pretty happy. The strongest wave/curl at the back of my head has slightly returned after three weeks but my hair is still incredibly easy to manage to what it was. I will have it again.

  4. Hi this is an interesting article.. It has some valuable information. I have been straightening hair for over 15 years … I do the Japanese Hair Straightening. I believe that it is the same thing as re bonding… I also don’t think it needs to be super complicated but it is time consuming! I do not require my clients to return to the salon unless they wish to.. There is also a Japzillian hybrid that gives the best of both worlds!

  5. Thank you for making my choice easier. Keratin it is. For those of us who don’t want their hair Damaged, it seems the obvious Choice.

  6. Cindie Hahn says:

    Have been doing Japanese for about 5yrs now. Great results about 4hrs 350″$. However now want to go back to curly so guess I have to cut my hair really short to get back my curls..bummer..haven’t decided yet but sick of the expense!!

  7. Rebounding is actually the same as Japanese Straightening. With Japanese Straightening you do not have to return to the salon several days later. Also, I’ve performed straightenings in as little as 3 hours ( rare) and as much as 7 hours ( also rare). I’ve been performing Japanese Straightenings ( Thermal Reconditioning) since 2005. Not trying to be argumentative but there are some erroneous facts here. Other than that, good article.

    If you have an allergy in hair dye? Do can you go in hair rebonding?

    I’ve been doing keratin for over ten years. It’s amazing. Your hair doesn’t frizz in humid weather, and over time the product has gotten cheaper, faster, and safer. I will probably keep doing it every six months for the rest of my life.

  10. Lei says:

    In Japan you don’t have to return to the salon. It only took me around 3 hours for med/long ish thick hair, and results lasted almost a year before needing retouching. No noticeable damage for me either!

  11. Alia says:

    I have been wanting to get keratin but I have been scared, I heard people lost hair is it true?

      We always recommend going to a good hairdresser to discuss these options 🙂

    I have been getting japanese thermal reconditioning for many years and it is the only way i have smooth hair but the problem is finding the right person to do it. Many will rush through the process and the results will not be good. You have to find someone with experience and patience.

    • carly says:

      Patience is a virtue Kara and it seems to have paid off for you. Thank you for the tip 🙂

  16. Jill says:

    I have been getting my hair Japanese straightened for over 13 years now. My hair is now waist length..i have it touched up about every 18 months. I don’t have curly hair, but it’s thick and bushy. Took her 5 hours today. It never in all the years I have been doing it has damaged my hair. The flat iron used to damage it. Now my hair can air dry which means less heat. Never had to go back the next day..

    My grandaughter is 1/2 black and 1/2 white and wants her straight . It takes hours just to dry it and straighten it. And only last a couple days . Her hair is very thick with tight curls. Would the keratin treatment work on mix hair

    • carly says:

      Hi Tammy thank you for your post! As your granddaughter is mixed race we would recommend a hairstylist who specialises in afro hair and they can recommend the best treatment or relaxant to help achieve the results that she wants. I hope this helps 🙂
