Can anyone tell me which olaplex product is best to buy for an at home treatment?
It's quite confusing, I am looking at No 3 and No 6 but not sure which is best or do I need both?
Should I buy No 4 and 5 too or is that not really necessary?
I have never had the salon treatment done (No 1 and 2) so am I wasting my money anyway?
I've got colour on my hair and it's in fairly good condition but it could do with a bit of nourishing.
