Great to use before No.3 treatment
I apply it for 10mins before No.3, my hair loves it. I use both products together, never tried them separately, repeat purchase for me

Frizz Fighting for Fine Hair
This is the third time I’ve bought this product and I’ll continue to do so as it really helps my fine frizzy curly wavy hair behave itself better. I use it along with the olaplex 3 as an intense bond treatment and my frizz is hugely reduced after I have used it. The only small downside is the spray comes out as a line of squirt as opposed to a misty spray so you do have to be careful with the application! But the results are great. I also use the olaplex 8 deep conditioner

Not sure what it does but great!
I can’t say for sure that adding this into the no. 3 routine how much better it makes it but I know my bleached hair is super shiny and thriving!

Highly recommend!
I only use this when I want to add an extra step to my hair routine and treat myself. I let it sit and then pair it with No. 3 and my hair always thanks me later. My only issue is the nozzle needs to be reworked as it does not distribute as a fine mist.

Great product - let down hugely by spray nozzle
This is a great product which I use with No.3. I do feel that the nozzle lets the product down significantly though, hence why I have only given this 3 stars. In order to thoroughly dampen the hair, it would be much better to deliver the product via a mist to allow greater control of where the product goes. The jet wets one area whilst leaving other areas dry meaning you have to use far more of the product than you need and you have less control over where the product goes. A mist would be far easier to control and distribute through the hair and far less expensive (better value = better customer experience) and a better user experience overall. At this price, you shouldn't have to decant the product into another bottle with a mister to be able to use it effectively or use twice as much (or more) to get all your hair damp enough.

Really love it with No. 3
Wasn't sure what to expect but have been trying different products to strengthen my hair after a bad dying experience - I used this with the No.3 hair perfector treatment and was so so happy with the results, this combination works well for my fine highlighted hair to smooth and calm the frizz from breakage!!
