My color-safe shampoo lasts a year, cleans deeply, and keeps hair vibrant without damage.
This shampoo's tiny amount creates rich lather, preserves color vibrancy for a year, and restores my damaged hair to silky health effortlessly.
This is a review from Amazon.com about product:
Olaplex No. 4 Bond Maintenance Shampoo, Repairs, Strengthens, & Nourishes All Hair Types, Adds Shine & Leaves Hair Feeling Soft, 8.5 fl oz

A little goes a long way. I forgot that and used the amount I use with other shampoos...Whoops! So many suds.
This has been my go to shampoo especially when I have color. My bottle has lasted for an entire year and I still have a bit left. I found some shampoo I needed to use up, so I didn't use this for a couple months and forgot how well it works. Cleans well, my hair looks healthy and I highly recommend this if you color or damage your hair.
Shampoo Basics & Tips
Why "A Little Goes a Long Way" Matters
Shampoos with concentrated formulas require smaller quantities to create lather. Sulfate-free surfactants (like coco-glucoside) generate suds without stripping color or natural oils, explaining the user's initial "whoops" moment when overpouring.
Color-Safe Formula Science
Color-safe shampoos use gentle cleansers and UV filters to prevent dye molecules from escaping hair cuticles. They often contain proteins (keratin) to seal frayed ends, aligning with the reviewer's "healthy look" observation.
Longevity Secret: pH Balance
A pH between 4.5-5.5 (matching hair's natural acidity) reduces frizz and breakage. This extends bottle lifespan by minimizing excessive use, as described in the "year-long usage" experience.
Suds vs. Effectiveness
Contrary to belief, abundant bubbles don't equal cleaner hair. The reviewer's "so many suds" note highlights the formula's efficient lathering agents, not harsh detergents that fade color.
Repair Mechanisms for Damaged Hair
Ingredients like panthenol (pro-vitamin B5) penetrate strands to improve elasticity, while ceramides rebuild the hair's lipid layer – explaining the "healthy" results post-color damage.
I adore this shampoo for adding shine, a fresh clean feel, and enhancing my hair's natural highlights beautifully.
This shampoo consistently gives my hair a glossy luster, a deeply clean sensation, and makes my highlights stand out vibrantly, leaving me thrilled with my hair's overall health and appearance.
I love buying shampoo in gallons for endless supply, refilling bottles with its sweet bubblegum scent that kids adore.
I appreciate purchasing shampoo in gallon quantities for a reliable long-term supply, allowing me to refill existing bottles at home. The bubblegum fragrance is delightfully clean and particularly appealing for children's use.
I found this shampoo effective, but its high price compared to Walmart's deal makes me question its value.
In my use, this shampoo provided decent cleansing and lather, yet I'm unsure why it's priced higher than Walmart's $1.14 version. It left my hair feeling clean, but the value seems lacking for everyday needs.
I find this panthenol shampoo cleanses well with coconut fragrance, however greasy.
I selected this shampoo for its panthenol and shea butter ingredients. The coconut aroma is pleasant, and it washes my hair thoroughly, but I notice a greasy residue afterwards.
I found this shampoo excellent for enhancing my red highlights, it's affordable, and doesn't stain my hair.
I highly recommend this shampoo because it effectively maintains my red color, is cost-effective, doesn't cause running or staining, and smells great, even if it slightly dries my hair ends.
I use shampoo as body wash for its fresh smell and soft skin benefits.
I have used shampoo as a body wash for years because it smells amazing, keeps skin hydrated with built-in conditioner, and lasts long with rich foam.
