Exactly! I use 0 and 3 because they contain the most of the active ingredient that bonds, which works to re-bond the 2 broken, former, singular, disulphide molecule. Yes, that's right. It's only active when it's wet. Thus, I use the No. 0 to wet my ends and let it sink into my hair for 10 minutes. Then I re- spritz again to rewet my hair with the No. 0 right before dabbing on No. 3, as the No. 3 needs the No. 0 to penetrate.
I rinse my ends every day. My leave-ins dissipate over the course of the day. Silicones are in conditioners and leave-ins are quite substantive. Therefore, contrary to what is stated, these silicones rarely come out with a single day wash and condition.
Therefore, unless the average person using silicone based conditioners and leave-ins is truly stripping these products from the substrate, which is the hair, then their hair is about as clean or dirty as mine upon their 'normal' use of the Olaplex products.Thus, I believe that the daily rinsing I do on my ends is good enough to allow the No. 0 and No. 3 product to penetrate sufficiently, adequately and effectively into my [non-washed] hair.
It is also important to remember that these Olaplex products were absolutely NOT formulated with afro-textured hair in mind. These products were specifically developed to combat the oxidative damage that is incurred when using peroxide to strip the hair of melanin, or bleaching, in order to color hair hair very blonde. That hair is usually overwhelming hair of Caucasian women in terms of the largest number of clients. After that it might be hair of Asian women, then followed by perhaps an even lesser number women of African descent with relaxed or natural afro-textured hair.
As a consequence, the way an afro-textured, natural haired person uses these products is likely to be quite different than the way the aforementioned intended client with blonde hair as the end goal might use them. My ends are fragile and vulnerable. I don't need this product on my roots. Conversely, blonde hair would absolutely need this product from root to tip as they dyed their entire hair strand which tends to be extremely damaged by the dyeing process, where the severity of the damage increases incrementally with the amount of time the bleach is left on the hair.
Thus, I think - I'm good!
