I ended up purchasing this after my last hair colour appointment which was over a year ago and I still have some left so it lasts for ages.
The treatment comes in a spray. It's the standard purple colour and design of the colour shampoo and conditioner. It's made of 100% vegan ingredients. The spray states it has 21 essential benefits but there are too many to list but I mainly purchased it to help with detangling knots, protecting my hair colour from fading and to reduce frizz.
I apply by spraying onto my clean damp hair and combing through prior to drying. It does an excellent job at protecting my hair from the heat of the dryer and reduces drying time. It also works well on dry hair inbetween washes to detangle knots. I just spray a few times on my ends and brush through. I always notice a big difference in my hairs condition when I don't use this spray as my hair doesn't seem as soft and smooth and is harder to brush. I like that it doesn't leave my hair feeling weighed down but still adds enough hydration.
It is fairly pricey at $42 but it does last forever.
Basically a wonder spray. Smells good, sprays a fine mist, does what it says. I have very bleached hair, that can go frizzy and unmanageable at times. This spray really helps to tame and soften my destroyed hair strands. Makes my hair straighten or curl much easier too! Bonus - it smells delicious too! So many people tell me my hair smells good when I have used it. Also does not weigh the hair down at all!
Tips: Use on damp hair before brushing or drying. Only need about 4-6 sprays.
