Effective
Great product, quick in its effectiveness. However, the bottle is a bit too harsh to use. Overall, good experience and would recommend to use it with other Olaplex products.

Always in my stash
I use this with number 3 every 6 weeks or so and before I get highlights. Definitely makes a difference to my fine colour damaged hair.

Great primer - use on great lengths hair extension
I use this primer with olaplex 3,4 & 5 on my bleached blonde hair and great lengths keratin bond hair extensions- really repairs my hair ! I transfer it to a proper spray bottle to get good coverage as the actual bottle it comes in just spurts out quick and you end up loosing a lot of it to the air and floor !!!

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!
