Love this brand, love the smell, the results and the feel. I use the no 9 in combination with the leave-in no 6. I have curly hair and use this as a first step when I brush my damp hair. It helps with untangling and forming my curls. I follow with the no. 6 to style. Sometimes I finish with Olaplex oil at the ends too. Not sure if that last step adds anything that's a must. The No. 3 I use before shampoo once a week. Have only had in in my hair a couple of minutes and not the 15 advised. Still I think my hair looked better after.

My hair has so many split ends and heat damage. Using these makes my hair so soft and shiny!

This is a very powerful duo! By buying this you give your hair the reconstruction and protection it needs against colouring and heat! I have repurchased number 3 several times and I haven’t regretted it once! This is the first number 9 I bought and it’s also high quality and does what it promises. 

This is Olaplex quality for all hair strands, especially those which have gone through a color change. Highly recommend these, saved my hair a couple of times!

my hair is so dry, due to having dyed my hair blonde over the years. but these two together have strengthen my hair and leaves my hair feeling silky smooth after wash day. since using these two together, I have noticed a significant decrease in split ends and longer times between wash days, only having to wash my hair one/two days a week.
