This article tries to answer as many of the most common questions about Brazilian Keratin Treatment as possible. The links below will take you to the most relevant section to your quesiton. But first, the most common issue:
What Shampoo should I use?
A Good Shampoo for Brazillian Keratin Users
The best shampoo to use must be a sodium chloride (salt) free shampoo and, ideally, suplhate free. Most of the shampoos in the market contain sodium chloride. Eluence produce a shampoo at £20.
It is the Sodium Chloride which is bad for the BKT treatment as it washes it out quicker, which is why swimming in the sea a lot of sweating too much can also be a problem for BKT users. Swimming in a pool is problematic if there is a high chlorine content.

What is Brazilian Keratin Treatment?
o Brazilian Keratin Treatment has numerous names including:
• Keratin straightening
• Brazilian blow out
• BKT
• BKST
• Brazilian Keratin hair straightening
• Escova progressiva (the Brazilian name)
• “the permanent blow dry”.
It is a treatment that is designed to give hair that “just out of the salon, blow dried look”.
In brief it works by applying a product, Keratin to the hair and then sealing that product to the hair. The net result is that hair is normally straighter (as if it had been blow dried straight).
For more details see here and a video here.
• If a person has the BKT treatment the net result is that they will generally have straighter, more shiny, more “healthy looking” hair.

What happens during a Brazilian Hair Straightening Treatment?
* During a treatment the hair is first washed, with a clarifying shampoo, to open up the cuticles. Then the treatment is applied, which contains the Keratin. Then heat is applied through straightening irons. The heat seals the Keratin into the hair and so removes the frizz.
Back to top
How long does BKT last?
o Between two to four months. BKT is not permanent and is eventually washed out.
The more the hair is washed, the quicker the keratin will be washed out.
o If hair is washed one a week it may last 4 months, if its washed 3 or 4 times a week then it may last two months. For this reason three months is the most common average for the length of a keratin treatment.
What does hair look like after is has been treated?
o BKT normally makes the hair look shiny and more healthy. Surprisingly the hair can also feel softer. Keratin provides a lot of nutrients for the hair, hence it looks so good afterwards.
Back to top
How much does BKT Cost?
o Its not a cheap treatment and costs vary, depending on the salon, from £200 to £500 per treatment.
Can you use Brazilian Keratin Treatment at home?
o No. The procedure involves a very long and detailed hair straightening process using irons and driers. It takes over 2 hours, and this is not something somebody can “have ago at”.
DIY is not a good thing!

I have very curly hair will Keratin Treatment give me straight hair?
o Possibly not, it will depend on the exact hair type. If its incredibly tightly curled hair then you may end up with soft curls
Back to top
What is X-Tenso and Yuko?
o These are both Japanese hair straightening products. They work by applying a chemical to the hair that stays on the hair for the rest of its life. The hair is permanently straight and will only return to its natural method as the hair grows.
Back to top
Which is best BKT or Yuko/ X-Tenso?
o They are very different treatments and it depends what you want. The former allows for flexibility and a more natural look, the latter is a longer lasting treatment.
Back to top
Does it matter if I get my hair wet after keratin treatment?
o Yes, initially. BKT is not permanent and comes out in the wash; the less the hair is washed the longer it lasts.
o For the first 3 to 4 days after Brazilian Keratin Treatment the hair should not be washed, and then it should only be washed with a sodium chloride free shampoo and conditioner
Back to top
Will sea water damage my hair after BKT?
o No, but it should be avoided. Sea water, which is salt water (and salt is Sodium Chloride), washes the keratin out of the hair quicker than normal water.
For this reason swimming in sea water reduces the life span of a BKT treatment.
Back to top
Can I go swimming after BKT?
• Brazilian Keratin Treatment is washed out more rapidly by sodium chloride and chlorine. Sodium chloride (salt) is in sea water and chlorine is in most swimming pools and spas. So if your going to swim, and want to keep the BKT effect for as long as possible try and cover your hair.
Back to top
How soon should I wash my hair after BKT?
o About three to four days after the first treatment
Back to top
Do I have to wait 3 days before wetting my hair after keratin treatment?
• Yes, a minimum of three days, possibly four, depending on your hair type.
What shampoo should I use after Brazilian keratin treatment?
It must be a sodium chloride free shampoo. Most of the shampoos in the market contain sodium chloride; Eluence produce one at £20.
However, the same product can be purchased for just £7 from this site. Even though the postage and packaging is expensive its still very cheap. If you can buy several you will get a very good bargain.

What conditioner should I use after Brazilian keratin treatment?
o The conditioner, like the shampoo, this needs to be sodium chloride free. As the sodium chloride washes out the keratin faster.
The conditioner can also be bought cheaply from this site.

Is Brazilian Keratin Dangerous?
o No. There are two types of BKT. BKT with formaldehyde (commonly referred to as just BKT without an reference to the formaldehyde ) and BKT without formaldehyde, commonly referred to as BKT formaldehyde free. Some people do not like the formaldehyde product, due to the nature formaldehyde – it is a potent chemical.
Back to top
What Chemicals are in BKT?
o BKT contains ether, Keratin, and more often than not formaldehyde. Unless its specifically states its “formaldehyde free” then it will almost certain contain that.
Back to top
Are there problems with Keratin getting into your eyes?
* During the treatment it is a possible that you could get the product in your eyes, much like there is with any bleach, shampoo, or conditioner. During the treatment its possible the fumes given off could go in to your eyes.
This is not problematic, any more than getting shampoo in your eye – merely wash it out.
Back to top
Brazilian Keratin Treatment and Sodium Chloride, what is the issue?
o Sodium Chloride, which is salt, is found in both sea water and most shampoos. In its self it is harmless and will not damage the hair, however it does wash keratin off quicker than normal water, reducing the life span of a BKT treatment, therefore is should be avoided.
There are shampoos available that do not contain sodium chloride.

Keratin Treatment and formaldehyde, what is the all the debate about?
• BKT has been available in the UK for the past few years, famously used by Girls Aloud; it has been in the US for much longer.
The primary chemical in BKT is Keratin – which holds the hair. However, most BKT treatments also have formaldehyde in it.
• Formaldehyde is not a nice chemical, and has been linked to cancer. There are no known cases of death or even illness from its use in BKT, and the concentrations are so low, and the exposure so minimal it is unlikely to have an effect for the customer. The stylist, on the other hand, has regular exposure to the chemical, on a daily basis and for this reason some hair dressers simply will not work with it.
Back to top
Does your hair fall out after BKT?
o No, not all
Back to top
Are there any problems associated with using Keratin?
o No, none, other than you have to wait for several days before washing it. The hair actually looks and feels better after the treatment.
Back to top
How many times can you use Brazilian Keratin Treatment?
o As many times as you want, as it is not harmful for the hair
Can keratin treatment be done again before it washes out
* Yes, can easily be done every month (funds permitting), as BKT does not harm the hair.
Back to top
Can I get my curls back after having my hair straightened?
o Yes. If you’re using BKT once it’s been washed out the hair will return to normal.
