What Is Actually in Your Products?

Not all hair products are created equal, and some contain ingredients that actively work against your colour and extension investment. Knowing what to avoid helps you protect your hair and get more value from your salon services. Here is what our team at Fluff in Denver recommends steering clear of.

Sulfates

Sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are the most common harsh detergents in shampoo. They create a satisfying lather but strip colour molecules from your hair with each wash. For colour-treated hair, sulfate-free shampoo is essential — not optional. For extensions, sulfates dry out the hair and shorten its lifespan significantly.

Alcohol (Drying Types)

Short-chain alcohols like isopropyl alcohol, ethanol, and SD alcohol evaporate quickly and take moisture with them. They are common in hairsprays and styling products. Long-chain fatty alcohols like cetearyl alcohol and cetyl alcohol are actually beneficial — they are conditioning agents. Check labels and avoid products where drying alcohols are listed in the first five ingredients.

Avobenzone

This common sunscreen ingredient is found in many products that claim UV protection. Avobenzone breaks down when exposed to minerals in water and can cause a chemical reaction that turns blonde or light-coloured hair orange or pink. If you use spray sunscreen, be extremely careful to keep it away from your hair — or switch to a mineral-based sunscreen.

Silicone Buildup

Silicones like dimethicone are not inherently bad — they smooth the cuticle and add shine. However, non-water-soluble silicones build up over time if you are using sulfate-free shampoo that cannot remove them. This buildup makes hair feel heavy and look dull. Use water-soluble silicones or clarify periodically.

Salt in Styling Products

Sea salt sprays are popular for beachy texture, but regular use dehydrates hair and accelerates colour fade. Use them sparingly and always follow with conditioner. For extensions, salt-based products should be used minimally — they dry out extension hair faster than natural hair.
