    A review of the Kerastraight KS Ultimate smoothing keratin treatment for all hair types. By Simply Cantara - a healthy lifestyle blog


    A month ago I had the chance to have a keratin straightening treatment on my naturally curly Afro hair with the KeraStraight KS Ultimate treatment. I had actually been searching for straightening treatments and blowouts but I didn’t like the fact that a lot of these treatments meant you couldn’t wear your hair curly for a few months. So it was as if the hair fairies (they’re a thing, right?) had seen my Google searches and sent the lovely KeraStraight team to my inbox! They offered to do the KS Ultimate treatment on my hair live on stage at the Salon International exhibition at the London Excel Centre. I figured if they were confident enough to do my hair in front of hundreds, if not thousands of people then I must be in for a good result!

    Before I get into the treatment and my Kerastraight review, let me tell you a bit about my hair…

    My hair history

    For 10 years I chemically relaxed my hair to make it permanently straight. Relaxer is strong stuff, let me tell you. I’ve had hairdressers leave the relaxer on my hair too long because they’ve gone off to wash someone else’s hair, leaving my scalp burnt in places. I’ve also had a terrible relaxer where clumps of my hair were falling out as the relaxer was washed out – it was horrific! It got to a point where my hair wouldn’t grow past my shoulders because the ends of my hair were so damaged they would just break off. Relaxer works well for a lot of people, don’t get me wrong, but it didn’t work for me anymore.

    2-3 years ago I stopped relaxing my hair and left my hair to grow out, trimming off my relaxed ends. I wasn’t ready to deal with my curly hair as for the past 10 years I had only had straight hair. Thick, curly, afro hair was foreign to me, so I started wearing clip in extensions, straightening my hair to blend, then I switched to weaves. The weaves meant my hair was left in peace, away from relaxer and heat and my hair grew! My hair is in much better condition and is back to being thick again, although I have heat damage in the front. I still enjoy wearing my hair straight, but it gets so frizzy and difficult to maintain straight styles. Enter, the KS Ultimate

    My Experience with the KS Ultimate

    I was a hair model for KeraStraight at the Salon International event at the Excel centre, which meant I had my hair done on stage in front of hundreds, if not thousands of people. On arrival I had my before pictures taken and was introduced on stage, I told the crowd what my hopes were for my hair (frizz control, manageability and to be able to wear my hair both curly and straight) then I was taken behind the stage to have my hair washed and a pre-treatment cleanse applied. As my hair is thick it was left on a little longer to open up my cuticles ready for the Keratin treatment.

    I was seated on stage and my hairdresser Matthew Roskell detangled my hair and sectioned it. Taking a small section at a time he applied the KS Ultimate treatment and combed it through with a fine tooth comb. There are no harsh chemicals in the KS Ultimate so Matthew did not have to wear gloves when applying it and there was no strong, awful smell. I was sceptical that they would find my hair difficult to manage as I have had several bad experiences with hairdressers, but I needn’t have worried, not once did I feel my hair being yanked or pulled. Once the treatment was on my hair, Matthew covered it with a plastic cap and left it for 45 minutes, checking it regularly. My hair seemed to draw in a crowd as they were intrigued to see what the KS Ultimate would do to my hair – as was I!

    45 minutes later the keratin treatment was washed off and the Kerastraight Moisture Enhance Conditioner applied and rinsed off. That’s something I really liked about the KS Ultimate over other keratin treatments – you do not need to blow dry and straighten the treatment into your hair on a high heat to seal it in, you only have heat on your hair to style it at the end. Seeing as I have heat damaged hair already, I did not want a lot of heat on my hair so the KS Ultimate was perfect for that. Matthew then seated me back on stage and began to blow dry my hair. Already my hair was feeling softer and less frizzy than it does when I blow dry it. He then straightened my hair using the Kerastraight EasyComb and the Titanium Iron 1.5. I couldn’t believe the results! My hair was glossy, soft and silky, it felt like European hair. I couldn’t stop beaming and the crowd were equally impressed. People who had seen me earlier in the day couldn’t believe I was the same person. I was on cloud nine!

    One Month On

    When I left the Excel Centre it was raining; normally my straight hair would start to frizz instantly but I managed the long walk to my car with no frizz whatsoever. My Mum was stunned at the results, knowing full well what my hair is normally like. I was nervous to wash my hair as I didn’t want to undo anything. I had been given the KeraStraight Moisture Enhance Shampoo and Conditioner so I washed my hair with those and popped on the KeraStraight Ultimate Oil.

    Normally I would divide my hair into 4 sections and detangle it with a wide tooth comb, starting at the ends and gently working my way up to the roots. Detangling would take anywhere between 20-40 minutes. This time I was able to just brush my hair and detangle it in less than 10 minutes! I always air-dry my hair when I’m going to straighten it to minimise the amount of heat I use. My hair dried quicker than normal. I applied heat protectant then straightened my hair with my own straighteners and the KeraStraight EasyComb that my Mum had bought me (thanks Mum!). My hair went back to being lovely and straight, only it wasn’t quite as shiny (I can never recreate that ‘just left the salon’ look at home!). Going from freshly washed hair to straightened was so much easier and quicker – I was so happy!

    Again, my hair handled frizz easily, even when I went clubbing for my friend’s birthday. The club was a sweat box, incredibly humid and normally my hair would have frizzed up to the point where I’d have to tie my hair up to go home. Not this time! My hair frizzed a minimal amount, not enough to ruin my straight hairstyle or to warrant me having to tie it up.

    The next time I washed my hair I decided to leave it curly to see how it would be. I finger detangled my hair with conditioner on it so as not to disturb my curls too much. I washed out the conditioner and left my hair to air-dry. My hair was still really curly, but my curls were slightly looser. Instead of shrinking to above my shoulders when it had dried, my hair was still past my shoulders and soooo soft! Now I can wash and go, apply some leave-in, curl definer and leave my hair to air-dry. After having the treatment, I thought I’d wear my hair straight all the time, but I’ve been enjoying having curly hair that is easy to manage so much that I’ve only straightened it twice in a month!

    The picture below shows a before and after comparison of my hair freshly washed and air-dried with zero product on it. Before the treatment, my hair would shrink above my shoulders, now it dries about 2-3 inches longer. All I need is a bit of leave-in and a curl defining cream and I’m good to go!

    I wanted to leave it for a whole month before posting this as I wanted to thoroughly test it. The results I got from the KS Ultimate seemed too be good to be true so I was sure something would go wrong. One month on and I am still so in love with it. I can honestly say it lived up to its promise – it has cut the time I spend on my hair in half, from washing to drying to straightening. My hair is softer and my curls are looser but still super curly. I don’t have to fear the rain or a sweaty gym session now and my hair is so much easier to manage. When I was on stage there were ladies with all hair types getting their hair done, so I wholeheartedly recommend KeraStraight treatments to everyone.
