KERATASTIC Review: How Good Is This Premium Keratin Hair Treatment?

Permanently straight hair without frizz is the dream for many women and men. Keratin treatments promise these results. While you can go to the hairdresser for it, keratin smoothing can now also be done with ease at home. 

However, there are hundreds of keratin products, many of which are unfortunately not recommended because they damage the hair. Therefore, care should be taken when choosing your treatment. In this test report, we take a closer look at the premium keratin smoothing from KERATASTIC.

How good are KERATASTIC products really? Can they live up to what they promise? Here, you will get all the information at a glance.

What Does KERATASTIC Keratin Treatment Do?

KERATASTIC keratin treatment was developed to smooth curly, frizzy hair over the long term and leave it looking sleek. It ensures long-lasting results of up to 3 months.

Without frizz or fuss, it makes hair so much easier to care for. You can save tons of time on blow-drying, straightening, and styling your hair. In addition to the smoothing effect, your hair also becomes velvety soft, healthy, and shiny.

What distinguishes KERATASTIC Treatment from other products?

In contrast to other products, KERATASTIC products are of very high quality. Other products often contain formaldehyde and other chemicals that damage and break down the composition of hair. KERATASTIC relies on high-quality active ingredients that are good for the health of the hair. They repair and care for damaged hair from the inside out.

In addition to the high product quality, the keratin smoothing from KERATASTIC also delivers better results than other keratin products. Hair is smoother, softer, and healthier. Plus, these effects last much longer. Some customers report that the effects lasted up to 6 months for them. However, it must be noted here that this depends very much on the personal hair type and the initial position of the hair before applying the treatment.

We also noticed that the KERATASTIC product smells wonderful. After other keratin smoothing, hair smells with a foul odour for weeks. With KERATASTIC, the opposite is the true.

KERATASTIC products are sometimes even used by professional hairdressers, who charge their customers around £250 or more for keratin smoothing.

So, with KERATASTIC, you get the same result for a fraction of the cost and with a simple application you can easily do at home. If you are thinking about going to the salon for a keratin smoothing treatment, we recommend that you try it yourself with KERATASTIC at home first. You can save a lot of money and have beautiful, sleek, smooth, and healthy hair to show for it.

The Advantages of KERATASTIC

These are the reasons why KERATASTIC is so loved by many people and is also the first choice of some hairdressers.

  • Provides longer-lasting results
  • Nourishes your hair from within to give it a healthy look
  • Has no nasty chemicals in the formula

  • And on top of all that, it’s the top choice for many salons and stylists everywhere when it comes to keratin treatments.

    How to Make KERATASTIC Results Last Even Longer

    After keratin straightening with KERATASTIC, you should definitely not use shampoo and styling products that contain salts or sulphates because these allow the results to be washed out faster.

    In order to be able to fully enjoy the effects of KERATSATIC, you should definitely get the After Care Set, which ensures perfect hair care after straightening.

    On the official website, there is an all-in-one bundle that contains all the important products with the Clarifying Shampoo, the Keratin Treatment, a Smoothing Shampoo and a Smoothing Conditioner to permanently smooth the hair and maintain the result for as long as possible.

    KERATASTIC Keratin Hair Treatment Price 

    The keratin smoothing treatment from KERATASTIC currently costs £69. This includes the Clarifying Shampoo and the Keratin Treatment. A bottle contains 100 ml, which can provide approximately 2 applications for long hair. For those with shorter hair, you can get more applications from it. 

    Although the price is higher than other products, it is justified by the high product quality. If you compare the costs with a professional keratin treatment at the salon, the price-performance ratio is actually quite good.

    The smoothing shampoo and the smoothing conditioner for after care each cost £25.00 You can get them together in a set for £39. The bottles contain 285 ml and last for about 1 – 2 months, depending on how often you wash your hair.

    We recommend investing a little more money in a high-quality product than destroying your hair with cheap products that contain harmful chemicals.
