Olaplex No.4 Bond Maintenance Shampoo

Cleansers USA Approx. $33

The wash-day step of the patent that started the bond category. The No.7 oil already lives on this shelf; this is the maintenance shampoo built on the same molecule, which makes it the rare shampoo that belongs to the repair half of this edit rather than the cosmetic half.
