Top Toxic Haircare Ingredients to avoid. From a Non Toxic, Jacksonville Salon.
When it comes to healthy hair, what you leave out of your routine is just as important as what you put in. Many mainstream shampoos, conditioners, and styling products contain harsh or misleading ingredients that can damage your hair, irritate your scalp, and impact long-term health. At Phi Eco Salon in Jacksonville and Jacksonville Beach, we believe in transparency, sustainability, and using only non-toxic, eco-friendly hair care products.
Here’s a guide to the most common ingredients to avoid in your hair care — and why.
1. Sulfates (SLS & SLES) Found in most Drugstore Products
Harsh detergents used in household cleaners that create foam but strip your scalp’s natural oils.
Why avoid: Dryness, irritation, faded color, frizz.
Better option: Sulfate-free cleansers with aloe or plant-based surfactants.
2. Parabens
Chemical preservatives that disrupt hormones.
Why avoid: Endocrine disruption, eco-toxicity.
Better option: Natural preservatives like vitamin E.
3. Formaldehyde & Formaldehyde-Releasers
Found in some keratin treatments.
Why avoid: Carcinogenic, scalp/respiratory irritation.
Better option: Organic smoothing treatments.
4. Phthalates Hides uner the Ingredient “Fragrance”
Common in synthetic fragrances.
Why avoid: Hormone disruption, reproductive risks, environmental harm.
Better option: Products scented with essential oils.
5. Silicones (Non-Water Soluble)
Coat hair to feel smooth, but cause buildup and dryness. Prolonged use can lead to hair loss
Why avoid: Blocks moisture, dulls curls, requires harsh shampoos to remove.
Better option: Lightweight natural oils like argan or jojoba.
6. Synthetic Fragrance & Dyes
Hidden chemicals that cause irritation.
Why avoid: Scalp sensitivity, headaches, allergies.
Better option: Fragrance-free or essential oil–based products.
7. Coconut Oil (Overused or Misapplied)
While often marketed as a miracle ingredient, coconut oil doesn’t work!
Why limit/avoid: Can coat hair and block moisture, cause buildup, and leave curls dry or brittle in humid Florida weather.
Better option: Lighter oils like argan or grapeseed, which penetrate hair more effectively.
8. Glycerin (in Humid Climates)
Glycerin can be helpful in moderation, but in Florida’s extreme humidity, it often works against curls.
Why limit/avoid: Pulls too much water from the air, causing frizz and puffiness. In dry weather, it can pull moisture out of your hair, leaving it brittle.
Better option: Humectants balanced with proteins and oils, such as aloe vera or honey-based products.
9. Sodium Hydroxide (Lye) Found in all Redken, Biolage, and many other Professional Products
Sodium hydroxide, also known as lye, is a strong alkaline chemical used in hair relaxers and straightening treatments.
Why avoid:
Extremely harsh on the scalp and hair
Can cause burns, breakage, and long-term thinning
Alters natural curl structure permanently
Better option: Non-toxic, organic smoothing treatments or embracing your natural texture with hydrating curl care.
