This is a review from Amazon.com about product:
Jack Black - Double-Header Shampoo + Conditioner - PureScience Formula, Coconut Oil and Kelp Extract, Sulfate-Free, Removes Oil and Product Buildup, Lightly Conditions and Soothes, 16 Oz

This product does exactly what it says it does. My hair feels clean and very soft as the conditioner and mixed with the shampoo is a perfect blend. The smell is nice as well, but I am most happy with the way that it leaves my hair looking and feeling. After using this product, I don’t have to wash my hair for a couple days and it still looks and feels nice instead of extremely oily and dirty, like it did before I used this product
Shampoo Basics & Tips
The Science Behind Effective Shampoo Formulas
Modern shampoo formulations like this product combine surfactants and conditioners in a process called coacervation. This technology allows cleansing agents (typically sulfates or sulfate-free alternatives) to coexist with moisturizing components, creating the "perfect blend" mentioned in the review. The balanced pH level (5.5-6.5) helps maintain hair's natural moisture barrier.
Understanding Oil Control Mechanisms
The 2-day oil control effect stems from cationic polymers in the formula. These positively charged molecules bind to negatively charged hair strands, creating an anti-static shield that slows sebum distribution from scalp to hair ends. This explains the "not extremely oily" experience compared to conventional shampoos.
Fragrance Retention Technology
The lasting pleasant scent results from micro-encapsulated fragrance molecules. These time-release capsules break through friction during hair movement, providing continuous freshness. This technology differentiates premium shampoos from basic formulations where scents fade quickly.
Hair Wash Frequency Considerations
Reducing wash frequency (as mentioned "couple days") benefits scalp health by preserving natural oils. Over-washing strips sebum, triggering compensatory oil production. This formula's mild surfactants clean without over-drying, maintaining the scalp's microbiome balance - crucial for long-term hair health.
