  • 1x Humidity-Blocking Frizz Shield Spray
  • 1x Heat Protectant & Styling Mist
  • 1x Glass Hair Shine Serum
  1. Shield (Damp Hair): After washing, apply the Humidity-Blocking Frizz Shield Spray generously to damp hair and comb through from roots to ends. This seals out moisture at the very first step—blocking humidity before your curls have a chance to frizz back up.
  2. Blow Dry: Blow dry in sections using a round brush, pulling hair taut and working downward to smooth the cuticle. Take your time here—this step sets the foundation for a sleek finish.
  3. Protect (Before Hot Tools): Before reaching for your flat iron or curling wand, lightly spritz the Heat Protectant & Styling Mist onto dry hair from mid-lengths to ends. Comb through to distribute evenly, then allow to dry completely before applying heat.
  4. Style: Use your flat iron or preferred hot tool to smooth, straighten, or shape into waves. The Heat Protectant & Styling Mist shields strands from heat up to 450°F while Fision® EcoSil builds shine with every pass.
  5. Finish: Pump a pea-sized amount of Glass Hair Shine Serum into your palm and rake through hair from mid-lengths to ends. This last step delivers an ultra-smooth, glass-like finish and keeps flyaways in check. For fine or oily hair, start with less and build as needed.

    My hair never looks this good straight

    Because my hair has been so thin, dry, and damaged for years i rarely use heat on my hair. When i was selected to test the kitsch heat protectant spray i almost declined because my hair always looks terrible straight. I figured why not give it a try because if it works in my hair it will work for anyone! I was amazed by the outcome. My hair was beautiful straight, it laid flat no flyaways, and my very dry ends even looked smooth and nice. The pictures below show how curly my hair normally is and how frizzy dry my ends can look, and how wonderful the heat protectant worked to give my hair shine when I straightened it! I still don’t use heat on my hair very much but i plan to keep a bottle of this heat protectant on hand for the few occasions i will.

    Love this product!

    I love adding the heat protectant spray to my daily routine. I spray it on my hair before curling and it keeps it from getting brittle. I have fine thin hair and this keeps it looking healthy when using heat on it. Love the smell also.

    Love this stuff!

    This spray is so nice! Not heavy and detangles too. Makes my hair soft and I felt it did a good job protecting my hair from the blow dryer. My hair is thin, fine and straight. This product did not weigh it down or make it greasy.

    WOW !!!!!

    Talk about a smooth clean look and feel!!!! Smells amazing ! For the first time in months I used a hair dryer and my hair dried so smooth and no frizzies!!!! I feel like my hair dried faster too ( or maybe it’s just I forgot since it had been so long ). My hair is long and fine so protecting it from heat is a priority. When I started Kitsch products I quit using heat in order to get the maximum benefit and quit causing damage while I was trying so hard to grow longer healthier hair. Yes, there are other brands I could have tried but I built a trust with Kitsch and am so glad to see this product now available ! Thank you Kitsch !!

    Incredible!

    This heat protectant is incredible! I have thin frizzy hair and when I used this, I could have left it in without even using heat! It tamed my frizz so well and my hair was still soft. The added bonus when using it with heat is the amazing shine my hair got afterwards! My hair is usually a dull dirty blonde and it was so shiny and smooth when I straightened it. Which is not the norm with other heat protectants I’ve used in the past. 100% love this!

    Light, very shiny, and nearly frizz free

    I've been looking for something like this for a long time. I put a pea sized amount in my very thick hair and it came out shiny and very nearly frizz free, as in there were only 2 strands of hair frizz sticking out. (My hair does what it wants.) It really brought out the shine in my hair. It looked like it was made of light.

    effective

    This is a lightweight serum that kept my flyaway prone hair smooth and in control. I didn't notice any additional shine, but the smoothing was effective. Kept my hair smooth for 2 days between washings. Light and didn't weigh my hair down. Minimal scent so it doesn't clash with perfumes worn. I did use more than the recommended amount on one occasion and my hair looked greasy, so use sparingly.

    Best Hair Serum!

    This is the best hair serum I’ve ever tried! I have fine, chemically processed (lifted) hair and can never seem to get my hair feeling as great as the day you go to the salon, but thanks to this serum, I can get that feeling in between salon visits. A pea sized amount works perfectly for fine hair. If you have a thicker, more coiled hair structure, then a nickel sized amount may be more suitable. This is a product I definitely recommend.
