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.

I loved the hand soap but the refill lacks richness and lather, though scent is good.

I expected the refill to match the bottles' quality. It's less rich, lathers poorly, but scent is good. Overall, mediocre.

I used this shampoo and it fixed my hair breakage, allowing healthy growth in just one month.

My hair used to break after half an inch, but this shampoo stopped that and promoted growth. Despite family history of thinning hair, it now grows well, but I dislike the inconsistent packaging sometimes.
