If you experience even a little bit of frizz, you’ve probably been told by your stylist to try a keratin treatment.

But like most hair products, keratin smoothing treatments are not created equal, nor are they meant for all hair types or textures.  Navigating the wide variety of (and often conflicting) information on salon websites and blogger websites can be completely overwhelming.

So to give you as much information as possible before you commit, here is as much information we can give you without seeing you in person.

1. Know What You’re Asking For

Hair salons, product companies and bloggers use different names for different treatments interchangeably, which is poor practice and totally confusing!

You either have a

  1. Permanent straightening treatment, which straightens out your hair texture by changing the internal structure of the hair strand or
  2. You have a keratin smoothing treatment like Goldwell Kerasilk which helps de-frizz hair, add smoothness and shine, reduces styling times without changing the internal structure of the hair.

If you choose one, you cannot change your mind and have the other as they work against each other.  They are like Kryptonite to Superman: the ingredients in a keratin smoothing treatment will react badly with hair that is permanently straightened and cause it to become weak and brittle.  See our FAQs below for more information.

Within the category of Keratin Smoothing Treatments, there are generally two groups of  treatments:

  1. Those that do not contain harmful chemicals, like Kerasilk from Goldwell, our current preferred keratin treatment.
  2. Those that do. These treatments report a clean ingredient list but in testing, they fail the safe test. There is not enough ongoing testing and monitoring in Australia to keep product companies honest.

If you’re happy with your hair like movement and a bit of body but would love to cut down on frizz, go for a keratin smoothing treatment.

If you want your hair to look pin straight, go for a permanent straightening.

2. You Have to be Okay with Some Sacrifices

There is some downtime and “must-do’s” involved regardless of which treatment you go for.  Please read all of our FAQ’s below.

It is not uncommon to have some change to the colour of your hair whether it be coloured or natural: some clients experience fading, lightening or a change of tone after the treatment. There are a couple of reasons for this:

  1. A clarifying shampoo is used prior to the keratin process to ensure your hair is squeaky clean but this may also remove some colour;
  2. Heat: heat is used to bond the keratin to the hair.  Your stylist will test this first in an inconspicuous part of the hair to assess and then will adjust the temperature and number of passes (ie lower the temperature and increase the number of passes).  If this extends the time of your treatment it may affect the price of your service (because it takes longer).

3. Accept That Results May Vary

In reality, there’s no way to guarantee the results of a keratin treatment on your hair, regardless of the product promises of the keratin supplier.  It doesn’t matter what the “theory is”, people’s hair structure is different and will react differently to the process.

It can depend on

  • how strong the treatment is – generally the stronger the treatment the harsher the chemicals used.  We choose Kerasilk by Goldwell for it’s superior performance, ability to create a bespoke formulation for your hair type and hair smoothing goals (not everyone wants super straight!) and ingredient list that is the better than most.
  • How it is applied;
  • The temperature of the flat-iron;
  • How porous your hair is; and
  • About a gazillion other factors that you or us really can’t control.

But don’t let that scare you!

Just read our FAQs below, do more research, book a complimentary consultation today and  talk openly with our stylists about what your hair smoothing goals are.

What are the advantages of getting a keratin treatment

  • Smoother, Shinier Hair: One of the main benefits of getting a keratin treatment is that it can make your hair smoother, shinier, and more manageable. The keratin protein helps to fill in and smooth out the hair cuticle, which can reduce frizz and fly-aways and leave your hair looking silky and shiny.
  • Reduced Styling Time: Since keratin treatments can make your hair more manageable, you may find that it takes less time to style your hair after getting the treatment. This can be especially helpful for people with thick or curly hair, which can be difficult to style and manage. Remember to get the full benefit of a keratin treatment you must use a blow dryer or iron.
  • Long-Lasting Results: Keratin treatments generally last for months, depending on the type of treatment and how well you care for your hair afterwards. Improved Hair Health: Keratin treatments can also help to improve the overall health of your hair. The keratin protein that becomes bonded to your hair can strengthen and protect the hair strands, which can help to prevent breakage and damage.
  • Versatility: Keratin treatments can be customized to meet the specific needs of your hair and how you like to wear it. Whether you have straight, or wavy hair with some curl, a keratin treatment can help to improve its appearance and manageability. Hair that has tight curls can receive the treatment, but it won’t become pin straight,
  • Safe for Most Hair Types: Keratin treatments are generally safe for most hair types, including colour-treated treated hair, but NOT hair that has been permanently straightened within 2 yeras. So, it is always important to consult with a stylist and share your hair history before getting a keratin treatment to ensure that it’s the right choice for your hair.

Does keratin treatment damage hair?

While keratin treatments have many benefits for hair, there is some concern that they can also cause damage if not done correctly or if the wrong products are used. Here are some things to consider when it comes to the potential for keratin treatments to cause damage to hair:

  • Formaldehyde: Some keratin treatments in Australia used to contain formaldehyde, which can be harmful if inhaled or if it meets the skin or eyes. Formaldehyde can also cause damage to the hair, as it can weaken the hair shaft and cause breakage. It’s important to choose a keratin treatment that is formaldehyde-free. All the keratin treatments Lily Jackson Hairdressing uses are formaldehyde free.
  • Heat: Keratin treatments require heat to activate the keratin protein. However, excessive heat can cause damage to the hair, especially if the hair is already weakened or damaged. It’s important that the flat iron’s being used are professional quality with multiple heat settings and are only used for keratin treatments.
  • Incompatible Products: Using incompatible hair products after a keratin treatment can also cause damage. For example, using shampoos or conditioners that contain sulphates can strip the hair of the keratin treatment and cause dryness and damage. It’s important to use products that are specifically formulated for keratin-treated hair. As noted above, hair that has been permanently straightened within 2 years is not suitable for keratin treatments.
  • Hair Type: Certain hair types may be more prone to damage from keratin treatments. For example, if the hair is already chemically treated or damaged, it may not be able to withstand the processing involved in a keratin treatment. If you suspect this to be the case, we will perform some strand tests with your hair.

In summary, keratin treatments are best performed in a reputable salon like Lily Jackson Hairdressing, where you can be guaranteed of the technical skill and knowledge to provide you the correct advice and create the hair that you love.

Can you get a keratin treatment on colour treated hair?

Yes, it is generally safe to get a keratin treatment on colour-treated hair. In fact, many people with colour-treated hair choose to get a keratin treatment to help improve the condition and appearance of their hair. However, there are some important things to keep in mind:

  • Wait before colouring: It’s important to wait at least two weeks after getting a keratin treatment before colouring your hair. This will give the keratin treatment time to fully bond to the hair and ensure that the colour will be even and long-lasting.
  • Choose a colour-safe treatment: When getting a keratin treatment on colour-treated hair, it’s important to choose a treatment that is specifically formulated for colour-treated hair. This will help to ensure that the colour is not stripped from the hair during the treatment and that the treatment does not interfere with the colour.
  • Use sulfate-free products: After getting a keratin treatment on colour-treated hair, it’s important to use sulfate-free shampoos and conditioners. Sulfates can strip the colour from the hair and cause damage, so it’s important to choose products that are gentle and designed for colour-treated hair.
  • Consider your colour: If you have a lighter hair colour, such as blonde or highlights, sometimes a combination between heat and the keratin formulation can cause the hair to take on a yellow hue or become brassy. This is unavoidable in some cases but can be corrected by having a toner applied two weeks after. It is not a failing of the product or application if this happens as this is a known possibility.

Is it possible to DIE hair after a keratin hair smoothing treatment?

While it is possible to have hair breakage after a keratin hair smoothing treatment, it is not very common. The breakage can occur if the hair is over-processed during the treatment or if the treatment is done incorrectly. Here are some factors that can contribute to hair breakage after a keratin hair smoothing treatment:

  • Over-Processing: Over-processing the hair during the treatment can cause damage and breakage. This can happen if the product is left on for too long, if too much product is applied, or if the heat is set too high during the treatment. It’s important to follow the manufacturer’s instructions carefully and not to leave the product on for longer than recommended.
  • Incompatible Products: Using hair products that are not compatible with the keratin hair smoothing treatment can also cause breakage. For example, using products that contain sulfates or sodium chloride can strip the hair of the keratin treatment and cause dryness and breakage. It’s important to use products that are specifically formulated for keratin-treated hair.
  • Excessive Heat: Excessive heat from styling tools such as flat irons or blow dryers can also cause breakage after a keratin hair smoothing treatment. It’s important to use lower heat settings and to avoid using heat-styling tools too frequently.
  • Hair Type: Some hair types may be more prone to breakage after a keratin hair smoothing treatment. For example, if the hair is already weakened or damaged, it may not be able to withstand the processing involved in the treatment. It’s important to consult with a stylist to determine whether a keratin hair smoothing treatment is a good choice for your hair type and condition.

In summary, while it is possible to experience hair breakage after a keratin hair smoothing treatment, it is not very common if the treatment is done correctly and with proper care. It’s important to follow the manufacturer’s instructions carefully, use compatible products, avoid excessive heat, and consider your hair type and condition before getting a keratin hair smoothing treatment. If you do experience hair breakage after a keratin hair smoothing treatment, it’s important to consult with a stylist or hair care professional for advice on how to repair the damage and restore the health of your hair.

Can I use hair products shortly after a keratin hair treatment?

You should wait at least 72 hours (3 days) before washing your hair or using any hair products, to give the keratin treatment time to fully set and bond to the hair. However, some products can be used shortly after the treatment, while others should be avoided for a longer period. Here’s what you need to know:

  • Shampoo and Conditioner: You should wait at least 72 hours before washing your hair with shampoo or conditioner. This is because the treatment needs time to fully bond to the hair and washing it too soon can cause the treatment to be less effective. After 72 hours, you can use a sulfate-free shampoo and conditioner that is safe for use on keratin-treated hair.
  • Styling Products: You can use some styling products shortly after a keratin hair treatment, but it’s important to choose products that are safe for use on keratin-treated hair. Avoid using products that contain sulfates, sodium chloride, or alcohol, as these can strip the keratin treatment from the hair and cause dryness and damage. It’s also a good idea to use products that are designed specifically for use on keratin-treated hair, as they will be formulated to maintain the effects of the treatment.
  • Heat Styling Tools: It’s best to avoid using heat styling tools, such as flat irons or curling irons, for at least 72 hours after a keratin hair treatment. This is because the treatment needs time to fully bond to the hair, and using heat styling tools too soon can cause damage and reduce the effectiveness of the treatment. After 72 hours, you can use heat styling tools, but it’s important to use a lower heat setting

A: It depends on the hair type, length of hair, amount of hair and overall health of the hair.

  • Short hair (above the ear) takes 90 minutes

  • Hair below the jaw takes 3 hours or more.

The general process of Keratin Smoothing Treatment is outlined on this page.

A: The first treatment will last 3-5 months but is affected by the following factors:

  • If you use the recommended shampoo, conditioner and treatment products that prolong the life of the Keratin Smoothing Treatment.
  • How frequently you wash your hair.
  • How frequently you colour your hair and they type of colour you have.

Clients who have had more than one Keratin Treatment will generally get 5 months life out of their second and subsequent treatments (with proper care).


What to avoid after a keratin smoothing treatment

It’s vital that you treat your hair in the following manner in the first 48 hours of receiving a Keratin Smoothing Treatment.

  1. Do not wash your hair for 48 hours. 
  2. Avoid creating any creases or dents on the hair like tying your hair up with an elastic or ribbon, or pushing hair off the face with sunglasses.
  3. Avoid tucking your hair in back of your ear and do not wear hats.
  4. It is recommended to avoid going to the gym as this can affect your hair.

Hair colouring

It’s best to colour the hair two weeks after a keratin smoothing treatment. This should be performed in-salon by a professional stylist who is familiar with permanent hair straightening. Bleached hair requires greater precautions since the solutions can react differently depending on the different peroxides on the hair, causing uneven results. Always consult with a professional hair stylist for best results.

Ongoing care and styling

Use the professional keratin safe products recommended to you.  A keratin smoothing treatment is a heat activated treatment not wash and air-dry.  To maintain the smoothness, you must use a hairdryer or irons which take much less time (than if you did not have the keratin treatment).

A: Yes. The solutions do not contain any chemicals that produce formaldehyde or any other cancer-causing substances. Nor do any of the solutions come into contact with your skin.  There is a certain amount of steam generated by the keratin being bonded to the hair but we ventilate our salon to minimise this.

Goldwell Kerasilk uses glyoxylic acid (or a derivative of it) to lock the hair into a straighter position.

The good news: It is 100 percent formaldehyde-free.

Despite toxic ingredients containing formaldehyde causing substances being illegal in Australia, formulations are not closely monitored.  Fortunately Kerasilk from Goldwell has been tested extensively and the company issues a formaldehyde free statement.

A: No.

While many manufacturers says “Yes”, our experience is that there are a significant number of factors that affect outcomes and some may not be within our or your control.

African American hair types are not suitable as the inner structure of their curly hair strands are very strong, too strong for this type of treatment.  Similarly with some of the mediterranean hair types that are coarse and curly, smoothing may be achieved but will still require smoothing with blowdrying and tongs.

Hair that has been bleached (including highlights) will benefit from a Keratin Smoothing Treatment but there may be some change to the colour of the hair which can be addressed two weeks after the treatment.

A: No.

If you colour your hair at a salon, our preference is that it be done at least 2 weeks after the keratin treatment. Applying both chemical treatments simultaneously will result in hair damage, so do them separately to avoid undesirable results.

The manufacturer says you can also get your colour done 2 weeks prior, but that isn’t the best idea since the clarifying shampoo, the keratin complex and application of heat to your hair MAY cause your colour to fade or change.  Why risk it?

Waiting two weeks will ensure the keratin is well and truly sealed into your hair and colour application takes place afterwards with little or no impact to the keratin (maybe with the exception of colour services using bleach).

A: Depends

If the previous service was a true keratin smoothing treatment and not a permanent straightening, then YES, it is fine.

But many clients visit us and really don’t know what type of treatment they had.

To complicate matters, there are some brands of permanent straightening that use Keratin in their product names.

The tell tale sign is how smooth your hair is 5 months after the service: if the entire hair strand from roots to ends starts to kink or frizz then it is likely you had a keratin smoothing treatment.

If however there is definite regrowth of curly or frizzy hair and the rest of the strand is still straight then we recommend you coming in for a strand test with us for a small fee.
