    Frequently Asqued Questions

    What does Smooth Therapy™ treatment do?

    Smooth Therapy™ treatment offers professional-grade results with long-lasting smoothing, frizz reduction, and hair straightening. Powered by plant-based amino acids, it enhances smoothness, shine, and manageability.

    Our customisable treatment and comprehensive quick guide empower you to achieve your desired outcome, whether it’s defined curls, frizz control, or straightened hair.

    Experience the transformative effects of this single application for up to 5 months.

    Can Smooth Therapy™ straighten my hair?

    This customisable treatment offers the versatility to define curls, smooth frizz, or straighten hair for up to 5 months. If you desire straight hair, Smooth Therapy™ treatment can help you achieve that result.

    By using a hair straightener with titanium plates and following the instructions in our Quick Guide.

    The straightening effect achieved with Smooth Therapy™ treatment looks more natural, allowing your hair to gradually return to its natural state over time.

    Moreover, you will have the freedom to create waves with curling irons or style your hair in any desired way.

    How many application is one bottle enough for?

    The 100 ml spray bottle of Lotion is designed for 1-2 applications, depending on your hair’s length and thickness. It’s important to apply a generous amount of the solution to ensure complete saturation. Here are the recommended amounts based on hair length: Short (15-30 cm): 40 ml / Medium (30-45 cm): 60 ml / Long (45-60 cm): 80 ml / Extra-long (+60 cm): 100 ml. Try Me Kit also includes our home care shampoo and mask, which are specifically formulated for aftercare of the treatment.

    These products complement and enhance the results, ensuring your hair stays healthy and beautiful.

    Is it suitable for all hair types?

    Smooth Therapy is suitable for all hair types, including colored and bleached hair. However, when using a hair straightener on colored hair, there is a possibility of color fading. To ensure the best results, it is recommended to wait at least one week after the treatment before applying any hair color. For bleached, porous, or damaged hair, control the temperature by starting with a lower setting (170°C-190°C) and gradually increasing it while monitoring for color fading. Adjust the temperature if fading occurs. These steps help protect your hair and minimise damage or color fading during the straightening process.

    Is it free from harmful chemicals?

    Don´t worry, our treatment is formulated with a vegan and cruelty-free formula that is free from harmful chemicals like formaldehyde, carbocysteine, or glyoxylic acid. None of the active ingredients in the composition transform or release formaldehyde during application or the straightening process.

    Furthermore, you can expect a gentle and pleasant application experience. The treatment is ironed without any product on the hair, ensuring a smoke-free experience and eliminating unpleasant odors.

    What are the treatment after-care instructions?

    • Extend and enhance the effects of the treatment by using our Smooth Liss Home Care products, including Shampoo, Mask, and 14-in-1 Leave-In. (Home care shampoo & mask included in the kit).
    • Activate the smoothing effects by blow-drying your hair with hot air after each wash.
    • Maintain luscious and vibrant locks by repeating the treatment every 2-3 months.
    • Enjoy the freedom to style or wash your hair immediately after the treatment without any waiting time.

    What tools do you need to perform Smooth Therapy™ treatment?

    You will need the following tools: a hair straightener, hair dryer, hair clip, comb and towel.

    A high-quality hair straightener is essential for achieving successful results with the treatment, and we highly recommend using one equipped with titanium plates. When choosing a straightening iron, look for adjustable temperature settings within the range of 180°C to 230°C to ensure optimal performance. Moreover, our Lizze Extreme Straightener Flat Iron, trusted by professionals worldwide for keratin treatments, is available for purchase.

    Enjoy an automatic 20% discount applied at checkout when you purchase it with your Try Me Kit.

    • I've been having my hair straightened for over 10 years, I have very fine & frizzy hair, this was so easy to use, and very happy with the result. I can always tell I like the result when I wake up in the morning and don't need to wash/wet or redo my hair. Means less hair washing during the week which is better for my hair. Thankyou

    • Despite a delivery hiccup, I reached out to customer service and they swiftly resolved the issue. I couldn't be happier with the results! My hair looks amazing. Highly recommend!

    • I've been using this treatment in my salon for one year, and we absolutely love it. Not only do we appreciate it, but our clients also adore it, especially the btx treatment. It's quick, and the results are simply insane and long-lasting.

    • Very easy to use & the results are stunning! My hair is so shiny & smooth. I've had so many comments that my hair looks great, I'm thrilled!

    • Ive had the keratin treatment done in hair salons, I just wanted to be able to do this from home because it is cheaper. I absolutely love this product to straighten my afro hair. I left the treatment on for 60 minutes. Only took a little under 3 hours total for me. Im hoping this will last me 6-9 weeks. 10/10 recommend!

    • Trabajé en un salón en España donde utilizábamos esta marca de alisado. Sin duda los resultados son muy buenos, se puede adaptar el tratamiento para hacer alisado o simplemente nutrición. Cuando me mudé a Londres, no dudé en recomendar este tratamiento en el salón donde trabajo actualmente y lo estamos ofreciendo ahora a nuestras clientas. Otra cosa buena es que ni hace humos, ni malos olores, lo recomiendo 100%!

    • I have to say, this is a great product! It's incredibly easy to use, and the results are absolutely fantastic. My hair looks amazing, and I couldn't be happier with it.

      Stephanie K.
    • As a professional hair stylist, I do keratin treatments regularly. I must say this is the best product out there. If you are following manufacturers instructions you should not smell the product, your client should not be experiencing any burning or itching or irritation whatsoever.

      Toni M.
    • I'll never stop using this product. it's really good for curly and fizzy hair. Be careful to follow the process for optimal quality results. Very good.
