Fix My Hair Intensive Repair Conditioning Masque

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

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.

A fatty alcohol used to soften skin and stabilize creams. Despite the name, it does not dry the skin.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A rich, solid-at-room-temperature oil that deeply softens dry skin and hair. It is well tolerated overall, but its high lauric acid content is considered comedogenic by many dermatologists, so it can trigger breakouts in people who are acne-prone.

A rich botanical oil from avocado fruit, used to nourish and soften the skin. It is generally well tolerated across skin types and provides conditioning benefits.

A rich plant butter from mango seed kernels, valued for its emollient and protective properties. It is generally well tolerated, though very rare allergic reactions have been reported; those with tree nut allergies may want to patch test first.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

Cold-pressed oil from olive fruit, valued as a carrier and emollient in skincare formulas. Well tolerated across skin types and delivers fatty acids that support skin barrier integrity.

A cationic conditioning agent used in rinse-off products like shampoos and conditioners to provide softness and detangling. Generally well tolerated but can cause irritation at high concentrations in some individuals.

A positively charged conditioning polymer used in shampoos and conditioners to reduce frizz and improve manageability. It is well tolerated and has been safely used in cosmetics for decades.

A long-chain quaternary ammonium compound used in rinse-off conditioners and leave-on styling products for conditioning and static control. It is well documented in cosmetic use with a strong safety record.

A silicone-based polymer with amino groups that deposits on hair to provide conditioning and smoothing benefits. It is extensively used in hair care products with a long track record of safe use in rinse-off formulations.

A fatty-acid and tocopherol-rich plant oil used as a hair and skin emollient; CIR's review of plant-derived fatty acid oils found no evidence of irritation or sensitization and a long history of safe use in food and cosmetics.

A protein fragment derived from animal keratin that helps hair retain moisture and improves strength and shine. It is well tolerated across hair types and does not carry the allergen risk of plant-derived hydrolyzed proteins.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

A widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

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 floral fragrance component and one of the EU-labelled fragrance allergens. Usually fine, worth watching if you react to scented products.

A jasmine-like fragrance compound frequently used in soaps and lotions. It is one of the 26 EU-designated fragrance allergens, though studies suggest its sensitization potency is comparatively low relative to other listed allergens.

Alpha-isomethyl ionone is a violet-scented fragrance material and one of the EU-listed allergens requiring label disclosure. Documented sensitization is more common with this ingredient than with many other listed fragrance allergens.

A sweet, hay-like fragrance ingredient naturally found in tonka bean and lavender. It is one of the 26 EU-designated fragrance allergens and is also subject to an EU maximum concentration limit in finished cosmetic products.

A rose-scented fragrance ingredient found naturally in geranium and rose oil. It is one of the 26 fragrance allergens the EU requires to be labeled by name because a minority of people develop skin sensitization to it, though most users tolerate it without issue.

An ester component found in lavender and other botanical fragrances. It is one of the EU's named fragrance allergens due to documented contact sensitization in dermatitis patients, particularly after oxidation and degradation of the parent materials over time.
