Dry Shampoo With Oat & Ceramide Dark Hair

A water or bran extract of rice containing ferulic acid, small peptides and starches. It is a traditional East Asian skincare staple with some supporting antioxidant and mild-brightening data, but most of that evidence comes from cell or animal studies rather than large human trials, so the "brightening" claims on finished products go further than the direct evidence.

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

Natural corn starch used to absorb excess oil and add body to cosmetic formulas. It is very well-tolerated and has a long history of safe use in personal care.

Finely milled oat that the FDA recognizes as an over-the-counter skin protectant for temporary relief of minor itching and dryness. Well tolerated, including on eczema-prone skin, with rare contact allergy in people with pre-existing oat or cereal sensitivity.

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

A refined cellulose derivative processed from plant sources, used as a thickener and texturizing agent in cosmetics. It is an inert polysaccharide with no known sensitization or irritation potential and is widely used in personal care and pharmaceutical formulations.

A cyclic oligosaccharide derived from corn starch that acts as a solubilizer and delivery vehicle for other ingredients. It is chemically inert, well tolerated, and has extensive use in pharmaceuticals and cosmetics.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

A synthetic ester used to thin out heavy formulas and help other ingredients absorb faster. It is considered safe as used by CIR, but it has a reputation among acne-prone users for feeling occlusive on skin, so people who clog easily may prefer to patch test or choose lighter alternatives.

The base most products are built on. It carries the other ingredients and has no safety concern.
