I really see the difference with using Olaplex 3 with 0 and without. My hairdressers recommended both together, rather than separately

For me, this is a miracle worker that boosts Olaplex nr 3 considerably. Also, it makes it easier to use nr 3 - I don't wash my hair before as I use nr 0 as a primer on dry hair that cuts through some little styling products in my hair, keep it for 10-20 min and add nr 3. Have dehydrated bleached highlighted hair and have used this combo for 5 years once a week.. makes my hair much stronger, less prone to breakage. I see the difference every time, when i go without for a month.

There is no product can do what no.0 do! It’s really irreplaceable product during any hair treatment journey!

I got the builder spray treatment with the mask and oil, out of them all, I find this one the least effective. The spray nozzle is like a spray gun.. so even distribution is impossible.. but I mean you can take out your enemies with how strong it is  😂 .. also it smells more chemical than I could tolerate.. am still going to use it but I dont see my self repurchasing this .. even if it works , there are other alternatives that I would rather use with the same if not better results 

Of course you can use only Olaplex N3, but I believe that complete treatment you get with these two combined. I feel the difference and will repurchase for sure.
