After 5 years, I trust this shampoo for gentle color retention, lasting softness, and revitalizing fragrance.
This shampoo delivers softness, subtle color retention, and lasting fragrance after years of use, though improved lid sealing during shipping is necessary to avoid messy leaks.
This is a review from Amazon.com about product:
John Frieda Radiant Red, Color Boosting Shampoo, Enhances, Protects, & Hydrates with Pomegranate Extract and Vitamin E for Natural or Color-Treated Hair, 8.3 Oz
Been using this product for 5 years. They tweaked it and the overall feeling of the shampoo is different as it comes out of the bottle. Leaves hair smelling good, and soft. Leaves a tint of color for sure. Does not attach to roots, but it does to older hair. COMPANY SHIPPED IT loos TOP, it leaked all over the box and onto other products (sunscreen tube) inside the box. COMPANY should seal or tape the lids for shipping.
Shampoo Basics & Tips
Shampoo Formula Tweaks
Shampoo formulas may change over time due to ingredient updates, regulatory requirements, or sustainability goals. Minor adjustments can alter texture, lather, or effectiveness, as noted by the reviewer.
Color Retention in Hair
Some shampoos deposit trace pigments to enhance or maintain dyed hair. This "tint" effect targets older, more porous strands rather than roots, which have tighter cuticles.
Hair Porosity Differences
Older hair tends to be more porous due to damage, allowing products like color-depositing shampoos to adhere better compared to healthier roots.
Shipping Leak Prevention
Liquid products require tamper-proof seals and pressure-resistant lids during transit. Leaks risk product loss, cross-contamination (e.g., sunscreen), and customer dissatisfaction.
Sulfate-Free Preservation
Gentle shampoos often omit harsh sulfates, necessitating alternative preservatives. Formula changes might affect viscosity or stability, impacting user experience.
After trying many shampoos, I found this one adds excellent volume and curl ideally for my hair.
I have used countless shampoos over time, and this is the first that actually adds good volume and curl as desired. While it's not high-end, it works effectively for my daily hair routine.
I used this shampoo for months with no allergic reactions, and it cleans my hair thoroughly, satisfying me completely.
As someone allergic to many shampoos, I tested this for several months and experienced no allergic reactions; it cleans my hair well and has made me very satisfied with its hypoallergenic performance.
I used Zenagen for thinning hair, and now it's full and thick, lasting seven months per bottle.
Over 15 months, Zenagen Shampoo transformed my thinning hair into full, thick locks. Its long-lasting nature means each bottle lasts about 7 months with bi-weekly washing, and I'm on my third purchase, utterly satisfied.
This shampoo makes my thick hair super smooth and shiny, with fantastic lather and a wonderful fragrance.
I love how this shampoo makes my thick hair smooth and shiny, with its rich lather and amazing scent, but I was surprised that it takes a lot of product to cover my shoulder-length hair, so the bottle doesn't last long.
I found keratin shampoo keeps my scalp soft and hair healthy after switching from baby shampoo.
As I aged, my scalp became dry, so I used baby shampoo, but it dried my hair. Now with keratin shampoo, my scalp and hair stay soft and healthy after months of use.
I overcame stubborn flakes by using this shampoo consistently after my scalp adapted to it effectively.
I defeated my flakes by persistently using this shampoo, with sit times adjusting from 20 minutes to shorter periods as my scalp adapted, proving highly effective for long-term relief.
