"The No.3 Plus by Olaplex is a new product that came out this year, 30% off, the first sale [...] I've seen since it launched. It's a three minute treatment, [...] you wet your hair, apply it root to end, wait 3 minutes and rinse off. I am very impressed with this so far, the strengthening and less hair breakage and damage. It's not cheap, but it's an awesome one."

"This is a treatment you're supposed to apply to your hair before cleansing. Leave it on for 3 minutes and then rinse it off and then cleanse. And it's supposed to help repair and heal damaged hair bonds. So, the bonds that are in your hair that with damage or coloring or heat treatment, they kind of can break and damage is supposed to repair it. And Olaplex is a great brand. For hair care, I'm basically Olaplex and Moroccan Oil and then K18 treatment occasionally."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
