Keratin hair straightening treatment + special promotion

by Sylvia

Keratin straightening treatment - brazilian blowout

I have rather frizzy hair, which is made worse by the very humid weather here in Singapore. So I regularly go for a keratin straightening treatment to rid my hair of the frizz. Style by Louis was kind enough to provide me with a complimentary treatment this time. so I could document it for this blog and tell you a little bit more about it.

What is a keratin straightening treatment or Brazilian Blowout as it is popularly known?

Keratin straighening is a special treatment that removes the frizz from your hair and makes it a lot straighter and softer. The straightening treatment is based on the hairs’ natural protein Keratin, and is not a permanent treatment. It will last for about 3-5 months.

I have found the keratin straightening treatment to be very effective for my frizzy and unmanageable hair. I hardly ever have to use an iron straightener now and can just blowdry my hair and go.

Although this treatment is commonly referred to as the brazilian blowout, this is actually a brand name. Not every hair salon uses the Brazilian Blowout products, (even though they may advertise it as Brazilian Bloowout™) but use other keratin products that achieve the same effect. The keratin treatment I received today was Kerastraight.

How does it work?

The process is quite straight forward.

1. Hair is washed with a special shampoo

2. Hair is then dried

3. Treatment is applied to the hair with a comb

4. The treatment is blowdryed into the hair

5. The treatment is then locked into the hair with a straightening iron

6. Some salons seem to wash the hair afterwards, but I was advised to keep it in for a couple of days

Here is a short video of the keratin treatment I received


  • This seems to be a safe treatment for the hair as no harsh chemicals are used. I have found my hair to be softer and in an overall better condition afterwards.
  • You will get straight, smooth and healthy looking hair in a short amount of time
  • As opposed to the Japanese Straightening Perm the brazilian blowoutdoes not need to kill any hair and instead of growing out, the Brazilian method ensures that the hair fades out and this encourages fresh growth of hair.
  • Feel like a star! It is claimed that celebrities like Halle Berry, Lindsay Lohan and Nicole Ritchie are all using it.


  • It is not cheap. Expect to pay well over $300 (depending on the length of your hair)
  • There have been some reports (by Oregon) that the treatment can be toxic if it contains formaldehyde. Some people have reported some irritation to eyes, nose or throat. Brazilian Blowoutand Keratraight report on their website that their products are now formaldehyde free and tests have concluded that the products are safe to use. Other products may still contain formaldehyde so it is advisable to check with your salon if the keratin products they use are free of formaldehyde.
  • If you are advised to leave in the product, it will take a few days before you can wash your hair.

Length of treatment and after care products

The Brazilian blowout and Kerastraight anti-frizz hair straightening treatment takes about two and a half hours to complete.

It is recommended that you use aftercare shampoo and conditioner products at home to prolong the effect of the treatment. You can find the full range of the original Brazilian Blowout products by clicking on the products at the bottom of this article.

Hi Sylvia,

It was really nice of you to share the voucher. i hope you can extend it also to me.. thinking of getting this treatment anytime soon as my hair is already getting unruly.

Thank you in advance and all the best to you! By the way you look fab in your hair.




Hi Irene, Just follow the instructions as listed above and you will have the voucher in no time.


Hi Sylvia,

Thank you for the post! I have naturally curly hair and while I do want my hair to look less frizzy, I would still like it to retain it’s original texture. Do you have any idea if I will lose my curls upon getting the treatment, or will they just become more manageable?

Thank you,


The treatment is not as strong as it once was, so I would think that you will not lose your curls and they will become more manageable. However, since I’m not a curly girl myself, I’m no expert with this. Best to talk to the salon directly and ask them for their opinion.


Hi, interested in doing the Brazilian Blowout. Are you extending vouchers? If yes, would love to have one. Many thanks. Anne


Hi Anne, Just follow the instructions as outlined above and you will get the voucher through email.

A colleague has recommended the Keratin hair straightening treatment so I am very interested in the special promotion! I am 40+ and have the same issues with frizziness that your model above does. Oh for that to be a thing of the past!
Can’t wait for details on how to try it!
Chris :)


Good luck Chris. The treatment is not as strong as it used to be so completely getting rid of the frizz may be hard, but it certainly helps. Just try it out and see if it works for you!

I need sleek and easy to manage hair!
*Thanks of the discount voucher* Your photo looks good~
I am lazy and not so good with smoothening my hair out with the hairdryer every morning. Although I love my curls (more wavy than very curly though), my curls stopped being cute when I started getting a little older (and the curls/waves just seemed to grow too wild).
My hair is frizzy so I always end up tying my hair in a boring ponytail. I recently colored my hair and I know that rebonding (even soft rebonding) seem to dry my hair out quite badly!
Brazilian Blowout please~


Hi Alda, Just subscribe as per instructions in article to get your voucher. Good luck!


can i also have a voucher i like the sound of this treatment..?!


Hi Freda, Just follow the instructions as outlined in the article and you will receive the link to the voucher.

carole kwang

please send a voucher for Louis. Thanks!


Hi Carole. Just follow the instructions from the article please


Hi, i would like to leave the treatment on for as long as possible. Is there a time frame for washing it out i.e 1 week max


I’m not sure Michele. The longest I have left it was 3 days, but after that you really want to wash it out. You should check with the salon what’s possible.


Hi Sylvia,
I just received a voucher. However, is the promotion still valid?


Yes, it is!


I went to have my treatment done about 1 month ago at Style by louis with the stylist Yoko. It’s been nearly 1 month and I can already tell the treatment is fading out.

This will not give you stick straight results (which isn’t what I wanted) but it will get rid of frizz and make your hair look healthier. There WILL be fumes as well, but it didn’t smell terrible. I just wish it would last a little longer because if it did cost $400 it would be CRAZY for it to only last 1 month.

I’m a little suspicious as to whether or not they used the actual product, since I never saw the bottle. He kept going to the room to get more product. I also noticed that on the Kerastraight website they are not listed as an OFFICIAL salon.

Overall the staff were ok. Not very talkative and didn’t really seem interested in bringing in new clients. They talked among themselves but not in English so I couldn’t understand. Maybe they treat you differently if you go in with a coupon :(

How long did your treatment actually last?


The treatments are not as strong as they once were and I also find them less effective now. Can’t really remember how long exactly the whole treatment lasts. Perhaps 2 hours?


I’m thinking of making an appointment to get this done. Were you almost 100 percent frizz free after the treatment?


It’s not as strong as it used to be so 100% frizz free only lasts a short time.


GAH you’re so cute omg. why are u so pretty *sobs miserably*
I’m only 15 and you look so beautiful oh god whyyyy…
haha any who, i had a question that I actually wanted to ask:
I want to get the treatment done, my hair is a little bit longer than shoulder length and it is quite wavy and incredibly frizzy (except a few mercifully good days haha).
did you experience any sort of hair fall with the treatment? like I had my hair rebonded two years ago (no regrets) and I adored my hair in all it’s pin-straight perfection but I had a horrible time with the hair fall… :(( Was hoping if this could get me the hair without making me half a head of hair lighter 😛 :) 😀
your blog is awesome <3


I have never had an issue with hair falling out. However, the treatment is not so strong anymore that you will get very straight hair, although this differs for every person. You may want to give it a try and see how it goes.


Is it possible to still get the voucher? I would like to add that this keratin treatment service offered by louis and co is not the Brazilian Blowout. The Brazilian blowout is a specific brand of keratin treatment.


I am keen to try this treatment? Is the voucher still valid?


yes it is.

Helen Nolan
