Hair & scalp science
Most everyday hair problems are about what sits on the hair shaft: buildup, oils, silicones and hard-water minerals. These guides explain the chemistry, what published research shows and which fixes to try first.
Are silicones bad for low porosity hair?
Not as a group: volatile and water-soluble silicones rarely build up, while non-volatile dimethicone in leave-ins can weigh down intact hair. Our guide decodes the INCI names and how to remove build-up.

Buildup, soap scum, hard-water minerals or rinsing. Match your symptom to a fix and learn when to clarify versus chelate.

Friction charges the strands and dry air keeps the charge on them; quat conditioners, humidity and gentler heat styling are the fixes with the most lab support.

Partly: lab studies show coconut oil penetrates hair and reduces protein loss, while mineral and sunflower oil mainly coat it. Our guide covers timing, overnight use, low porosity hair and scalp considerations.

Not when used one or two days between washes; the real risks are buildup, flammable aerosol propellants and the 2021-2022 benzene recalls. See the powder vs aerosol table and how-often schedule in the guide.
