My rosemary shampoo lathers richly with minimal product, lasting months effortlessly.
This rosemary shampoo surprises me daily – tiny drops transform into voluminous, scalp-nourishing lather that keeps my hair fresh for months per bottle.
This is a review from Amazon.com about product:
Avalon Organics Shampoo Rosemary, 11 oz

Really like the hint of rosemary in this stuff. A bottle lasts a long time, takes just a small amount for a full head of lather.
Shampoo Basics & Tips
The Science Behind Rosemary in Hair Care
Rosemary contains camphor and rosmarinic acid that stimulate blood circulation when applied to the scalp. This increased blood flow can promote hair thickness and potentially slow premature graying.
Why Concentrated Formulas Last Longer
High-quality shampoos use sulfosuccinate surfactants that create foam with 30% less product compared to standard SLS formulas. This concentration explains the extended usage period per bottle.
Lather Mechanics in Modern Shampoos
Foam formation depends on surfactant molecules aligning at water-air interfaces. Advanced formulations like this use coconut-derived coco-glucoside to build stable bubbles that effectively lift dirt without stripping natural oils.
Economic Impact of Durable Products
A 12oz bottle lasting 6+ months (vs average 2-month usage) saves 66% annual cost. This efficiency reduces plastic waste by 3 bottles yearly per user, combining personal savings with environmental benefits.
