Is this product suitable for daily use? Yes, but it’s best for occasional or statement styles due to its strong hold.
Can I use it on wet hair? It’s designed for dry hair application for optimal hold and styling control.
Does it leave flakes or residue? No, it’s non-flaky and washes out easily with shampoo.
Is it safe for color-treated hair? Yes, it’s safe and won’t strip or fade color.
Will it weigh down fine hair? Use sparingly—its lightweight texture won’t weigh hair down when applied correctly.
Does it offer heat protection? No, it’s a styling glue, not a heat protectant. Use a separate product before heat styling.
Can I restyle my hair after it sets? It’s best for fixed styles, but you can reshape slightly before it fully dries.
What’s the finish—matte or shiny? It offers a natural shine with a non-greasy feel.
Is it suitable for long hair? It works best on short to medium hair for sculpted or spiked styles.
Is this the full-size product? Yes, this is the 150ml retail size. Travel sizes may vary.
I’m so impressed with the level of service and the great work he did on my hair! It took less than 3 hours and he was done, and my hair colour, texture, everything was so perfect. For context, I have curly, black hair.. Can’t thank him enough for this… I LOVE IT! So many compliments too :)
I love it
This leave in spray is fantastic, it definitely got rid of any brassiness. Looked like I just left the salon. Love it!!!
Highly recommend this set. Each scent is amazing. Perfect for every day use. Delivery was fast and packaging excellent. No regrets with my purchase
Everything you need for application is included. Comes with plenty of product and good instructions. I would absolutely buy this kit again
I have very fine hair but often find hair moisture masks heavy leaving the hair almost oily looking but this is perfect every time and can use daily without issues, alway leaves my hair feeling soft and healthy looking, love it .
Amazing hair mask makes it smooth and frizz free
The pump delivers a good measure of product. Makes things easier to apply
Fabulous hair oil for curly hair. Fast delivery helps too
(Used after bleaching hair first, with bleach kit also from KESS) The Danger Jones color is an excellent professional product. It takes well to the hair without damaging at all. The colour is vibrant and really lasts even after many washes. Will absolutely be ordering this brand again
Great product, used it for years
I switched to Pureology after advice from one amazing hairdresser in Ireland few years ago and I never went back to other brands. I have psoriasis and super dry scalp and thick and abundant hair but extremely dry and Pureology is the only one company, which works amazing for both my skin and hair. I highly recommend this brand and I can guarantee that it’s worth to spend little more in exchange for visible effects. Plus you don’t need to use more of it (even if you have heaps of long, thick hair) - it’s foaming very well. After dying my hair I’m using red series for coloured, and damaged hair and it’s also great! Hair are smooth and shiny, frizz is calmed down and curls looks healthy after using both red and pink series. Thank you Pureology!
Great product and delivered quickly
Great hold for my fine curly hair
Fantastic product, I would recommend to anyone, particularly if dry skin is a problem using other soaps.
