My Shampoo Review: Thinned Texture & Chemical Smell Issues


The last 2 shipments I received shampoo that was thinned out and had a weird chemical smell to them. Either they are very old batches that have been sitting on a shelf for a while or they have been tampered with.


Shampoo Basics & Tips


Understanding Shampoo Consistency and Odor Changes


Thinned Formulation: Shampoo viscosity changes could indicate ingredient separation due to prolonged storage. Most formulas contain stabilizers that degrade over 2-3 years, potentially altering texture.


Chemical Smell Development


Shelf Life Factors: Preservatives like parabens break down over time, releasing volatile compounds. Temperature fluctuations during storage accelerate this process, creating unusual odors.


Batch Age Indicators


Production Codes: Manufacturers use Julian date coding (e.g., 22435 = 2022 day 435). Older batches exceeding 36 months may show quality degradation.


Tampering Evidence


Packaging Integrity: Legitimate shrinkage occurs naturally, but sudden viscosity changes combined with broken seals suggest possible dilution or contamination during handling.


Quality Preservation


Storage Conditions: Ideal shampoo preservation requires stable temperatures (15-25°C) and humidity below 60%. Improper storage accelerates ingredient breakdown.
