This shampoo's perm-like odor made me sick and lingered until I washed again.

The shampoo's unbearable smell resembles harsh perm chemicals, causing nausea that forces me to rewash with another product immediately after use.

This is a review from Amazon.com about product:

Celeb Luxury Viral Duo Color Depositing Colorwash Shampoo & Conditioner Set + Bondfix Bond Rebuilder, Semi Permanent Hair Color, Vegan Hair Dye, Extreme Red

I dont hate the color. actually what I really hate is the smell. to me, this stuff smells worse then a perm and makes me nauseaus and then the smell is in your hair until you was it with a different shampoo. if they would work on that then I would love it. but had to take off a star for the smell.

Shampoo Basics & Tips

Why Shampoo Fragrance Matters

Shampoo scents directly impact user experience. Strong chemical odors, like perm solutions referenced in the review, often contain ammonia or thioglycolates—known irritants that cause nausea or headaches. Fragrances linger due to bonding with hair keratin, especially in porous or damaged strands.

Causes of Unpleasant Shampoo Smells

Off-putting scents typically stem from: 1) Low-quality synthetic fragrances masking harsh ingredients (e.g., sulfates), 2) Oxidation of natural oils, or 3) Preservatives like formaldehyde-releasers. "Perm-like" smells specifically suggest alkaline compounds or sulfur derivatives.

Managing Scent Sensitivity

For sensitive users: Choose fragrance-free shampoos with NSF/ECOCERT certifications. Patch-test products before full use. Neutralize odors by rinsing with diluted apple cider vinegar (1:3 ratio) or using charcoal-based clarifying shampoos monthly.

Shampoo Selection Tips

Prioritize labels with "phthalate-free" or "essential oil-only" scents. Hydrating formulas (hyaluronic acid, glycerin) reduce scent retention versus drying shampoos. For colored hair, opt for sulfate-free options to prevent fragrance buildup.

Common Shampoo Concerns

Q: Why does shampoo smell linger? A: Hair's porosity traps fragrance molecules. Q: Can scents cause nausea? A: Yes—volatile organic compounds (VOCs) trigger olfactory-induced migraines in 30% of adults. Q: Solutions for residual odor? A: Cold-water rinses seal cuticles, locking out smells.
