DESCRIPTION

What It Does: Provides lawsone keratin-reactive orange-red colour for permanent natural hair colouring.

Why It's Used: The only natural permanent hair colorant – lawsone's covalent bonding to keratin provides permanent colouration unavailable from any other natural botanical.

How It Works: Lawsone (2-oh-1,4-naphthoquinone) undergoes michael addition to cysteine thiols in keratin providing covalent bond and permanent colour. ph affects reaction rate (alkaline accelerates). colour range: orange to deep auburn depending on starting hair colour and processing.

SOURCING & ETHICS

Vegan Status: Yes – from lawsonia inermis leaves

Halal Status: Yes

Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Well-tolerated by most skin types.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Good safety profile at recommended concentrations. ewg score: 1–2.

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Lawsone's covalent bonding mechanism (michael addition to keratin cysteine thiols) is fundamentally different from synthetic oxidative hair dyes (which form new chromophores by oxidative coupling inside the hair shaft). lawsone reacts with exposed thiol groups primarily at the hair surface and cuticle, providing surface-level colour that is permanent (covalent bond) but can be stripped by bleaching or thiol-reducing treatments.

DESCRIPTION

What It Does: Provides violet-red colour contribution as an oxidative coupler in permanent hair colour systems.

Why It's Used: Violet coupler for cool, red-violet, and purple-tinged hair colour compositions.

How It Works: M-aminophenol's amino and hydroxyl groups in meta-positions provide specific coupling to oxidised primary intermediates forming violet chromophores. combines with primaries to produce purple-red shades.

Typically Found In: Permanent hair colours

TECHNICAL DETAILS

Primary Category: Hair colourant – coupler

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Sensitivity Concerns: Well-tolerated by most skin types.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Eu annex iii restricted. warning label required.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

M-aminophenol's colour contribution (violet) vs p-aminophenol's colour (blue-violet) demonstrates how amino/hydroxyl positional isomerism on the benzene ring determines coupling chromophore geometry and therefore colour. the meta position provides coupling at different ring positions, creating different resonance structures in the indophenol product that absorb at shorter wavelengths (violet) than para isomer products (blue).

DESCRIPTION

What It Does: Provides the primary oxidative hair colouring intermediate for permanent hair colour systems.

Why It's Used: The standard oxidative hair dye primary – ppd is the most reactive and widely used primary intermediate providing the broadest colour range in permanent hair colouring.

How It Works: Ppd is oxidised by h2o2 to form a diamine quinonediimine that couples with secondary intermediates (couplers) to form large, permanently coloured indophenol, indoaniline, or bandrowski's base molecules. oxidised coupling products are too large to diffuse out through the swollen hair cuticle, providing permanence.

Typically Found In: Permanent hair colours

TECHNICAL DETAILS

Primary Category: Hair colourant – primary oxidative dye

Secondary Functions: Skin conditioning

Application Areas:

Facial Skincare

Body Care

Hair Care

Beard Care

Color Cosmetics (Makeup)

Dietary/Oral Supplements

Typical Concentration Range: 0.1%–3%

SOURCING & ETHICS

Vegan Status: Yes – synthetic

Halal Status: Yes

Source Notes: Commercially produced for cosmetic use. verify vegan/halal status with supplier.

SKIN COMPATIBILITY

Irritancy Rating: 1/5 – very low

Comedogenicity Rating: 0/5 – non-comedogenic

Sensitivity Concerns: Well-tolerated by most skin types.

Safe for Sensitive Skin: Yes

SAFETY & COMPATIBILITY

Safety Profile: Eu annex iii restricted: max 2% after mixing in ready-to-use product. requires mandatory consumer allergy warning. ppd is the most common cause of allergic contact dermatitis from hair colouring. patch test 48 hours before use.

Works Well With: Standard skincare actives

Avoid Combining With: No known significant incompatibilities

SCIENTIFIC NOTE

Ppd's oxidative coupling mechanism makes it both effective and allergenic: the quinonediimine intermediate that couples with dye couplers also forms hapten conjugates with skin proteins when it penetrates the scalp. these protein conjugates trigger type iv (delayed-type) hypersensitivity in 1-13% of hair colour users, making ppd allergy one of the most common occupational dermatoses in hairdressers.
