This shampoo cleanses my colored hair well, leaving it fresh, but results fell short for $40 price.
My colored hair stays fresh and clean with this shampoo, yet after a month, visible improvements are lacking. For $40, I expected better results and value.
This is a review from Amazon.com about product:
Keratin Perfect Keratin Color Smoothing Shampoo - 32oz

This shampoo works ok. Good for colored hair.
After washed, I can feel my hair is fresh and clean, however, I don't think this worth $40.
I have used one month, still cannot really see the result as what I expected.
Overall, I think there have more better options than this shampoo with same price.
Shampoo Basics & Tips
Colored Hair Shampoo Essentials
Shampoos for colored hair contain sulfate-free formulas to prevent dye stripping. They often include UV filters and proteins like keratin to shield hair from environmental damage. Freshness comes from mild cleansers that remove buildup without drying.
Evaluating Shampoo Results
Hair improvements typically take 4-6 weeks. Factors like hair porosity and routine consistency affect outcomes. Manage expectations: some shampoos maintain color but don't repair damage.
Shampoo Pricing Factors
$40 shampoos may include specialty ingredients like argan oil or bond-building complexes. Compare value by checking concentration levels and salon-grade certifications. Budget-friendly options with similar benefits exist.
Choosing Alternatives
When switching shampoos, prioritize pH-balanced formulas (4.5-5.5) for colored hair. Look for ceramides to strengthen cuticles and humectants like glycerin for moisture retention.
Daily Hair Care Tips
Wash colored hair 2-3 times weekly with lukewarm water. Always follow with conditioner focusing on ends. Use clarifying shampoos monthly to prevent residue buildup affecting freshness.
