I have now purchased all of the Olaplex range. This particular item you use by applying to dry hair so that it is saturated. I had to use ¾ of a bottle to wet my hair which is very thick and curly. I left it on 10 minuted or so and then applied no.3 on top of it for a further 10 minutes, then washed it out using the shampoo and conditioner in this range. I did notice my hair was easier to comb through after I had applied no3. So once I've used this particular product and I have a few bottles now with the different kits I've bought. I wouldn't be purchasing it again! The spray top which was my reason for buying this is absolutely rubbish, I had to buy spray bottles from Amazon to decant it into.
