Smooth and Frizz Free

My hair looked and felt so glossy and shiny after my first use of this old Plex nine. I had a trial size and I was addicted to it immediately. So I had to go buy a big bottle of it. Sometimes you can get it on sale when it's $18, so grab it when it's that price!

Not what I expected

Low expectations-unexpected results - Used as final product after Olaplex No. 0 and No. 3 treatments combined for 25 minutes followed by using Olaplex shampoo and conditioner. I applied the serum tip to root as suggested. I have very thick shoulder-length hair, so I'm certain I used a bit more than the directions say. I let it air dry, which is never a good idea. I have virgin hair, but at 52, the texture of my brown hair has begun to change, and I have probably 10% gray, which is mostly on the crown of my head. I have always had hair that isn't sure what it wants to be - wavy? eh, it thinks so. straight? I wish. curly? a few scattered loose ones. Halo of frizz? Absolutely. My hair isn't damaged by chemicals. It's just what I've got. I only blow dry about once a month. Flat iron 1 or 2 times. My scalp is not oily, and during the fall and winter months with low humidity, my styling stays for a long time. Spring and summer? Gloom and doom frizz from humidity, so daily ponytail or baseball cap. When my hair was very long, it was a long braid. A bit of hairspray to tame the halo. Anyhow, if you have read up to here, do yourself a favor and invest in the serum and all the rest of the Olaplex products mentioned. If I scrunched my hair gently, I would have had a presentable, almost no effort hairstyle. I'm definitely going to be using it more often. Im curious how it will work with a blowout. I'm confident I will be happy. The real test is what happens when the humidity kicks in.
