Andreia

Andreia Professional Permanent Colour is a vegan professional permanent hair colour range offering up to 100% grey coverage, long-lasting colour and high shine, intended for professional salon use only.

Andreia Professional 0% Ammonia is a gentler permanent colour option within the same range, created for clients with sensitivities or salons wanting a low-odour, comfort-led colour service. It still delivers permanent results and grey coverage while offering a milder experience on the scalp.

Andreia Professional Power Blonde is a vegan ultra-lightening permanent colour designed for controlled blonding and up to 5 levels of lift. It provides a clean, even blonde result while helping maintain the hair’s condition during processing.

As a professional permanent colour, results are designed to last up to 6–8 weeks, depending on hair type, shade choice, home care, and washing frequency. For best longevity, pair colour services with professional aftercare and colour-safe retail products.

Yes. The range includes intense natural and natural shades formulated to provide reliable grey coverage, including resistant grey hair. Correct shade selection, mixing ratio and processing time are key to optimum results.

All oxidative colour involves a chemical process, but Andreia is formulated with carefully selected ingredients like quinoa protein, prickly pear extract and avocado oil to help protect and condition the hair during colouring. The 0% Ammonia line is specifically developed to minimise scalp discomfort and odour. Always follow instructions, perform allergy tests and conduct a thorough consultation.

Yes. As with all professional oxidative hair colour, a patch test/skin sensitivity test is essential before application, following the manufacturer’s instructions and your salon’s safety protocol.

Apply a small amount of the prepared colour mixture (without washing it off immediately) to a discreet area of the skin, such as behind the ear or the inner arm, according to the instructions in the professional leaflet. Leave for the recommended time and monitor for any redness, itching or irritation. If a reaction occurs, do not proceed with the colour service.

Yes. Andreia is suitable for most hair types when the correct shade, developer and processing time are chosen. For very compromised or highly sensitised hair, a careful consultation and strand test are recommended before full application.

Andreia shades are designed to work within their specified systems. Always follow the manufacturer’s guidelines and mixing rules supplied with the product and use the recommended developers. For any advanced mixing (for example, combining ranges or using specific correctors), salons should follow professional technical advice or education from their distributor.
