Natural Hair Care, Essential Oils, and Scalp Peeling Contraindications

Flashcards covering the benefits of natural hair care, standard vs. organic cosmetic criteria, plant origins and safety precautions for essential oils, and contraindications for scalp peeling.

Natural hair and scalp care (Benefits)

A hair care approach that provides less irritation and fewer allergies compared to synthetic surfactants (PAS), maintains the natural balance of the scalp over the long term (does not damage cuticles or remove the skin's protective barrier), and supports ecological and sustainable practices.

Natural cosmetics

Cosmetic products that are required to contain 95% ingredients of natural origin, in contrast to conventional cosmetics which carry no such restriction.

Conventional cosmetics

Cosmetic formulations that have no minimum requirement for natural origin ingredients, meaning 100% of the ingredients may be synthetic.

Organic (ecological) cosmetics

Cosmetics that must contain 95% ingredients originating from certified organic production, distinguished from standard natural cosmetics which consist of 95% natural ingredients and up to 5% synthetic ingredients.

Plant sources of essential oils (EO)

Volatile substances found across different botanical parts: flowers (rose, neroli, ylang-ylang), leaves (mint, eucalyptus), roots (ginger, vetiver), fruits (lemon, orange, anise, caraway), bark (cinnamon), wood (sandalwood, cedar), and resin (boswellia).

Phototoxic and neurotoxic essential oils

Potentially hazardous volatile oils, exemplified specifically by citrus essential oils, that require strict caution during application.

Hypersensitivity test (EO)

A mandatory precautionary test performed prior to essential oil use to prevent skin irritation and hypersensitivity reactions.

Lavender and tea tree essential oils

The only two exceptions to the strict rule that essential oils must never be applied undiluted directly to the skin.

Peeling contraindications

Specific skin and scalp conditions where peeling must not be applied: seborrheic dermatitis, acne, eczema, active infection (lichen/ringworm), wounds or minor lesions, and lice.
