GirlyGirl24: so this is a really good example of someone who did not know what to expect from the keratin treatment. Your stylist clearly did a bad job of explaining what keratin actually does to the hair, so let me explain the steps of the treatment, and then what the treatment actually does.
first hair is clarified to remove any build up or oil from the surface of the hair and scalp it also helps to open up the cuticle and prepare hair for treatment this is an essential step and ensures proper absorption of the keratin.
next, hair is blown completely dry and the keratin treatment is applied, once it is applied it is then also dried.
The last step is the most important step in the keratin treatment. Hair is carefully sectioned off by stylist and then small sections are taken and gone over with a flat iron 8 to 10 times to ensure hair is completely 100% straight. This flat ironing process is not the result of the keratin treatment it is only to seal the keratin into the hair. This should not be expected as the every day result of the treatment but it is just part of the treatment itself. You must then wait 72 hours to wash your hair.
now let me explain what keratin is and what it does to help improve hair. Keratin is the protein in that hair is made out of. This treatment coats unruly locks with this natural protein which helps to create a barrier between hair and water in the air. This means that hair is no longer susceptible to humidity and can then withstand weather changes and natural causes of frizziness. This extra layer of protein also helps to create a more even surface on each strand, therefore hair is shinier, smoother, and straighter than it was previously. However, nobody should expect that the flat iron result on the first day of their keratin treatment should be the result that they should expect every single day, this is not the case. What you should expect from your keratin treatment is hair that dries 50% faster than it did before and when it is dry it should be much smoother and much more manageable. Most of my clients find they no longer have to use a flat iron to smooth their hair but those with more unruly textures will find that they may need to flat iron occasionally. A brush and a blow dryer is usually sufficient to smooth hair, as their hair is much easier to style.
again, I cannot stress enough that the flat iron results that you see at the end of your treatment is not what you should expect every single day. This is merely a part of the treatment process. However, your hair will be much easier to style and you will not have to deal with flyaways and frizz.
as for the comment that keratin makes hair flat, what I can say to this is that keratin does reduce volume in the hair, but this is mostly because it is reducing texture and frizz. Most of my clients find that after shampooing their hair a few times after the treatment much of their volume is restored. But I will not lie it definitely reduces some volume. For most people I find that not having to deal with unruly hair is much preferred over having a lot of volume. And most of the time volume can be styled into the hair using the right styling products and techniques.
I like to describe this product as a permanent styling product, or a long-lasting conditioning treatment, rather than a straightener or relaxer.
I hope this helps clear up some confusion on what to expect from your treatment. I honestly feel like you will be very happy with it. Most of my clients say that this treatment changes their life. I know that is an extreme statement but for people who have had to deal with unruly hair their whole lives without any answers or help it truly makes a difference.
