Our take on the Olaplex No.4 Bond Maintenance Shampoo, 8.5 Fl Oz

Olaplex No.4 is a concentrated sulfate-free shampoo built around the brand's patented bond-building chemistry, the same technology behind its salon treatments. It cleans gently while targeting broken bonds from bleaching, coloring and heat, and it is marketed for all hair types. Reviewers with damaged or color-treated hair tend to praise the softness and shine; some with fine or oily hair find it heavy, and a few report it left their scalp dry or their hair limp. It sits above drugstore repair shampoos on bond technology but below salon-only bond systems in strength.

Best forColor-treated or bleached hairHeat- and chemical-damaged hairFrequent washers who want a gentler cleanserPeople already using Olaplex No.3
Pros
  • Patented bond-building technology rather than plain moisturizing
  • Sulfate-free and gentle enough for daily washing
  • Highly concentrated, so a small amount lathers well
  • Leaves hair softer and shinier for many users
  • Pairs with No.3 treatment for a full repair routine
Cons
  • Can weigh down fine or thin hair
  • Some users find it drying on the scalp
  • Lather is thinner than sulfate shampoos, which some dislike
  • Bond repair claims are hard to verify at home

Questions and answers

Is Olaplex No.4 worth it over a regular repair shampoo?
If your hair is bleached, colored or heat-damaged, the bond-building formula offers more than a standard moisturizing shampoo. On healthy hair the difference is smaller and harder to notice.
Does it work for fine or oily hair?
It is marketed for all hair types, but fine and oily hair types most often report it feels heavy or goes limp. Use a small amount and rinse well.
Can I use it every day?
Yes. It is sulfate-free and gentle enough for frequent washing, though some users with sensitive scalps prefer alternating with a milder shampoo.
Should I use it with Olaplex No.3?
Olaplex recommends pairing it with No.3 Hair Perfector. No.3 is a pre-wash treatment applied before shampooing, and the two are designed to work together.
Is it color-safe?
Yes. The sulfate-free formula is intended for color-treated hair and is widely used by people with bleached or dyed hair.
What size is this bottle?
This is the 8.5 fl oz bottle, the standard retail size. A little goes a long way because the formula is concentrated.

At Walmart, for $21.99, 33% under what the other stores charge, as of our latest check.
