  • Holds with amazing effectiveness
Shine, bounce, and softness in a hold? This is that miracle stuff that when you use it, it’s a bit of a sweet surprise to see how crazy great it works. It doesn’t seem to matter what the weather is outside, or how long my hair has been tucked into a surgical cap, my hair bounces right back to the style I wanted and love. How many products are out there that can really get rid of bad hair days? This was a first for me. ... show more

  • Forget Post Style! This is the best blow dry crème I’ve ever used!
Believe it or not, I bought both the pre and post Dyson products, and I accidentally used this as the pre-style crème. What a happy accident!! My hair had bounce, volume, and when I used it I had people ask me if I had just had my hair professionally done. When I didn’t use it, or used another product, my hair just looked normal. I have thin, fine hair; but I have a lot of it and it can sometimes run on the frizzy side - but no more! I used the entire container, and I repurchased the post style product again for use when blow drying my towel-dryer hair. I haven’t used it as a post style crème, because I don’t need anything on my hair after I style it. It’s amazing and worth every penny. Don’t bother with the pre style product. This one is all you need. ... show more

  • Too expensive but works great.
I love this stuff, and it works great as my hair will tend to get static and dry from the air straight. However, it is so expensive it’s almost prohibitive.

  • Made my hair shiny
I had a small sample from Dyson directly and then ordered the full size. Really like this product. It makes my dull, dry, coarse (“over a certain age”) hair look shiny. Doesn’t make my hair look oily. Only a small amount needed, so a great value for money.

  • Smells like a spa day in a bottle
The scent is spa - like. Feels so good in your hair. Not heavy or sticky. The bottle is reusable, and it dispenses small amounts that you can customize. I have thin, shoulder length hair, and use two pumps. My hair moves and shines, with a hold that's more subtle than hairspray.

  • Pre and post serum
I used the pre serum and post serum and didn't notice any difference than when I used the pre serum only
