This is great advice. Unfortunately, I tried to ease my hair into transitioning into what had become a lot of gray growth I could no longer keep at bay and I had several silvery washes and one round of bleaching to try and get rid of the part I'd been coloring for years. It was always going brassy and I just wanted to go gray already but with style. It was the bleaching that did a real number on my hair, turning it brittle and causing it to break off in a very alarming way. I didn't want to cut it all off so I'm letting it grow out and with what I already did to it, it's transitioning ok now but I can't undo the damage that was done by bleaching it that one time.
Here is a pic of the treatment that led to breakage, and here's what it looks like 6 months later. The gray is growing in naturally but the bottom has reverted to the yellowish color I was trying to get rid of. I'm told I have to just leave it or cut it off so I'm leaving it for now. The bottom pic is today after washing my hair with the Olaplex and letting it air dry; not a great look but pretty amazing compared to how it used to look if I let it air dry.
