10 NA is a basic, bright baby blonde and perfect for summer. I'm looking forward to testing Ion 9NA mixed with the 10NA. Probably a 3:1 ratio. I hope it works for you! I was surprised as I wasn't expecting that hint of shine. It's not massive, but it was nice.
It's not that I'm not an Olaplex fan. I'm not simply into it as much as everyone else. I don't feel every client has massively broken disulfide bonds. I work with two camps of clients: those that fry the living daylights out of their hair on a weekly basis and that that don't and only wash their hair once a week. Those that are breaking down the bonds with a flat iron and hair dryer several days a week, Olaplaex is great for them. I've found those that do not wash their hair often and never use heat, Olaplex has a slightly drying effect so I don't use it on them. And I have the less is more mantra. Especially for on scalp, if I even use it, I only use a few drops and don't up the developer. They have amazing customer service and I love the passion behind the product. At the end of the day, not every client has massively butchered bonds and not all of them need this treatment.
My Tom Cruise jumping on Oprah's couch moment will be when someone comes up with a product that keeps lightener from drying out before 50 minutes.
