Love this shampoo's rich lather and scent, though it lasts 28 washes, not 40 as claimed.
This shampoo's luxurious lather and refreshing scent wowed me, though it lasted 28 washes instead of 40—still a great value for the quality!
This is a review from Amazon.com about product:
Nexxus Color Assure Replenishing Nutrient Shampoo - 13.5 oz
Don’t get me wrong I love the shampoo lathers up great!!
Smell great!!
But unfortunately, it does not last for 40 shampoos as advertised I say about 28.
Shampoo Basics & Tips
Understanding Shampoo Performance Factors
Lather Quality: The reviewer praises the shampoo's rich lathering. Lather forms when surfactants trap air in water. While more foam doesn't mean better cleaning, it enhances sensory satisfaction and helps distribute product evenly.
Scent Longevity in Hair Care
Fragrance Retention: The shampoo's pleasant scent is highlighted. Fragrance longevity depends on oil-soluble aroma molecules and hair porosity. Products with cationic conditioners often retain scents longer by bonding to hair strands.
Shampoo Quantity vs. Advertised Washes
Usage Calculations: The discrepancy between advertised 40 washes and actual 28 stems from varying hair lengths and application habits. Manufacturers calculate based on 5ml per wash for shoulder-length hair. Thicker/longer hair may require 10ml, halving total uses.
Shampoo Preservation Tips
Shelf Life Optimization: Store shampoos in cool, dry areas to maintain efficacy. Exposure to humidity degrades surfactants and fragrances. Pump bottles preserve formula integrity better than open-mouth containers.
Common Shampoo Selection Criteria
Hair Type Matching: Always choose sulfate-free formulas for color-treated hair, clarifying options for oily scalps, and moisturizing shampoos with panthenol for dry hair. pH-balanced products (4.5-5.5) help maintain scalp health.
