Makes my hair so soft
Been using this once a week for the last year or so with number 3. It makes my hair look and feel so soft and healthy. Much easier to use now that it has a spray top on the bottle

It’s alright
If you have the extra money to spare it does make a great combination with olaplex no3 but it runs out super quickly and isn’t fully needed.

Not sure yet
I've used this twice now along with the No 3 and easing with No 4 and conditioning with 5. Haven't noticed any difference on my highlighted hair yet apart from that it doesn't look as dry.

Olaplex
Yet another firm favourite from Olaplex. Use it before No.3 to really nourish your hair, and help resurface the texture. Much welcomed hair therapy!
