  • Keratin Smoothing Treatment is a gentle de-frizzing and smoothing treatment

    Keratin Smoothing Treatment can de-frizz and smooth straight hair or curly hair — without using harsh chemicals.

    The results depend on the frizziness of your hair: curls can become smoother and softer with much less frizz, and the worse the condition of your hair, the more remarkably it can be invigorated. The effects last from one month up to three months and slowly wash out over time.

    Treated hair slowly returns to its natural condition. It is safe to repeat the treatment after about six weeks to get smooth, silky hair again should you wish.

    But YOU MUST USE A SALT-FREE SHAMPOO AND HAIR CONDITIONER: You MUST use a shampoo which is FREE FROM sodium chloride (commonly known as salt — INCLUDING 'dead sea salt' which you often find in some 'organic' shampoos).

  • What does Keratin Smoothing Treatment actually do?

    Keratin Smoothing Treatment for frizz-free, shiny hair

    Basically, Keratin Smoothing Treatment produces shinier hair. It can even be used on tinted hair. So, if you want a gentler way to calm your curls or fight off frizz, then Keratin Smoothing Treatment could be for you!

    What does a Keratin Smoothing Treatment actually do?

    Keratin Smoothing Treatment is a method of temporarily sealing liquid keratin into the hair with hair irons or heated hair straighteners. The benefits of Keratin Smoothing Treatment are:

    • Keratin Smoothing can smooth
    • Keratin Smoothing can soften
    • Keratin Smoothing is instantly manageable
    • Keratin Smoothing can shine
    • Keratin Smoothing can eliminate frizz
    • Keratin Smoothing can take just 90 minutes!

    After the treatment, your hair very slowly returns to its natural condition over many weeks. The good news is: it is safe to repeat the treatment after about six weeks to maintain smooth, silky hair, should you wish.

  • How long does Keratin Smoothing take?

    How long does Keratin Smoothing take?

    Keratin Smoothing Treatment can be done as quickly as in one and a half hours, or it might take as long as three hours. It all depends on the length and texture of your hair.

    We at denny hairdressing think that an average time would be about 90 minutes — why not consult us for a more precise estimate?

    What about bleached and blonde highlighted hair?

    Our product is especially manufactured for dark blonde to black hair and is not for use on light blonde hair, where discolouration may occur because the natural colour of Keratin may cause a yellow-brown cast on blonde hair.

    Will a Keratin Smoothing damage my hair?

    Our Keratin Smoothing Treatment does not damage your hair — it can actually enhance your hair.

    This is because keratin (which is a natural protein already in the hair shaft) is vital in helping to smooth out curls and frizz.

    Keratin fills gaps between the cuticle and the inner hair shaft and is sealed with a heated straightening iron. This treatment can smooth out curls.

    The keratin also gently bonds with your hair and helps to restore any damage that may have happened due to harm or environmental stresses.

    The results can be dramatic — and can last up to four months!

  • What is Keratin Smoothing Treatment procedure at the denny hairdressing salon?

    We start with our pre-Keratin Smoothing hair clarification or cleansing

    At denny hairdressing, we think it is essential that we carry out the following processes fully in order to open your hair cuticle:

    For normal or chemically treated hair — we give your hair two thorough shampoos using salon professional clarifying shampoo and then comb your hair through

    We blast dry and section your hair

    Next we quickly blast dry your hair with just a hairdryer and our hands

    Using section clips, we carefully divide your hair into four sections (from ear to ear and from front to nape). we then gently apply our the Keratin Smoothing Treatment from a bowl to your hair with a firm brush.

    We apply our Keratin Smoothing Treatment

    Starting from your nape we take 5mm (quarter inch or less), comb it straight and apply the treatment with our applicator brush. we carefully dip the brush into the lotion, remove any excess so that we can apply our keratin smoothing solution to each parting, starting just below root area and keeping the product off the scalp

    We then work it into your hair through to the mid-lengths and ends. we finger press it into your hair and finally gently comb your hair through from root to tip to ensure an even saturation over the section. of course we repeat the process with the other sections.

    We dry your hair carefully, thoroughly and just "snap & slide"!

    Using a paddle brush, we completely blow dry your hair starting at your last applied section ensuring the hair is dried thoroughly. we then divide your hair into four sections with clips.

    Now it's time to seal and infuse the treatment, using very hot straightening irons, set at 220 or 230 degrees centigrade.

    If your hair had been highly processed before, or was badly damaged or delicate, we would start the infusion process with irons set on a lower temperature of around 150 to 175 degrees centigrade. We will only increase the temperature if and when the condition and gloss improves until the hair is fully infused

    We start from the nape area with a fine tooth comb, part the hair into 5 mm (quarter inch or less) sections, comb clean like a board and flat iron the root section first. this is known as the "snap & slide" and we may need to repeat it as many times as necessary and then s–l–o–w–l–y pass the iron down the completed length of the section.

    We then "snap & slide" down the mid-lengths and ends of the section until your hair is fully infused with the keratin solution. we usually make more than 12 snap & slides per section, and it can sometimes take even more strokes until we are happy that all the Keratin Smoothing Treatment is infused into your hair. at each stroke it is possible to see your hair condition appear to improve with increased shine, strength and smoothness.

  • What do I have to do to care for my Keratin Smoothing Treatment?

    We suggest you follow our three Keratin Smoothing Treatment 72-hour rules

    Not everyone will tell you this, but you really have to take special care of your new hair — especially for the first 72 hours after it has been treated.

    Your hair is now like a new born baby, it can't look after itself at all and needs particular care and attention.

    You are the only person who can look after it properly — but don't worry, it's only for for 72 hours after treatment.

    We recommend that you occasionally run heated hair straighteners through your hair to help fix your keratin into your hair.

    1 — Avoid swimming or getting your hair wet!

    if you avoid getting your hair wet during the 72 hours after your treatment has been done you will find that its effects last much longer because you are letting your hair settle down naturally and are therefore giving the treatment the time it needs to take complete effect.

    please note that getting your hair wet in swimming pools or the ocean is much worse than plain water, and should be avoided completely!

    If you do actually get your hair wet during the first 72 hours after treatment it will become quite soft and will then be prone to being accidentally mis-shaped, so do your best to avoid getting it wet. should you get your hair wet the best thing to do is to blow dry your hair immediately and, if you can, use ceramic straighteners to restore its shape if necessary.

    2 — Avoid shampoo, hair spray, gel, mousse and hair products for 72 hours after treatment

    If you want your hair to look good for as long as possible — avoid all these chemicals for just 72 hours after treatment. of course you can shampoo your hair after the treatment, use hair spray, gel, mousse or any other hair products

    But if you avoid all these chemical treatments for your hair for a few days after your Keratin Smoothing Treatment, you will find that its effects can last so much longer because you are letting your hair settle down naturally and are therefore giving the treatment the time it needs to take complete effect.

    After these 72 hours, you must shampoo your hair using a sodium chloride free product. Sodium chloride (better known as common salt) is the only ingredient you must avoid in order to prolong the benefits of the keratin treatment because salt dries out and weakens the keratin links in your hair. Sulphates are OK in the shampoo — but make sure you avoid shampoos with ‘Dead Sea Salt' (which is still sodium chloride). Anything else with sodium in it is fine, so long as it is not sodium chloride (SALT).

    3 — Avoid wearing clips your hair, tying your hair in a ponytail, plaiting or braiding your hair, twisting it, or using ties in your hair for the first 72 hours

    You could wear a ponytail, clip, braid, plait, twist or tie your hair in the first 72 hours — but you will run the risk of introducing kinks or ridges into your hair. It's best to keep it simple and natural for such a short time.

  • What is in our Keratin Smoothing Treatment?

    We thought you'd never ask.

  • How does our Keratin Smoothing Treatment work?

    Most chemical products break down your hair and restructure it. However, the Keratin Smoothing Treatment is a safe infusion procedure with practically no threat of hair damage or breakage and the results are gentle and can last months. it can be used successfully on most kinds of hair, be it ethnic hair, virgin hair, dark blonde to black coloured hair, unprocessed hair, processed hair, dry hair, greasy hair or frizzy hair.

How to care for your Keratin Smoothing Hair Treatment

72 hours after your Keratin Smoothing Hair Treatment, you may shampoo and condition your hair — but you must make sure that both your shampoo and conditioner are FREE FROM sodium chloride — which is commonly known as salt. This includes 'dead sea salt', which is often found in some 'organic' shampoos.

ALSO NOTE: 'SLS FREE' does NOT mean that a shampoo or conditioner is 'salt-free', because 'SLS' is not salt, it is actually a cleansing agent.

So, always check the contents of your shampoo and conditioner very carefully.
