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.
