How to Use Andreia Hair Colour Products: Mixing Ratios, Timing & Handy Tips

Getting vibrant, salon-quality hair is all about using the right products correctly. Andreiaʼs hair colour range is designed for ease and great results, but knowing the best way to apply each product makes a difference. Below, weʼve broken down how to use some of their key products, including mixing ratios, timing, and a few insider tips to help you nail the look.

For lasting, rich colour that covers greys and lifts natural hair, the permanent cream is your go-to.

• Mixing Ratio: 1:1.5, use a non-metallic mixing bowl.
• Timing: Usually 30-40 minutes, depending on how much lift or coverage you want.
• Top Tips: 
• Do a patch test at least 48 hours before colouring - better safe than sorry! 
• Apply to dry, unwashed hair for better colour absorption.
• Start at the roots since they tend to process faster, then work through to the ends.
• Mix thoroughly so the colour develops evenly.
• Apply the co-wash post coverage for best results.

Want to go lighter and brighter? This oneʼs tailored for lifting your natural shade or existing colour.

• Mixing ratio: 1:2, use a non-metallic mixing bowl.
• Timing: 30-45 minutes, depending on your desired level of lift.
• Top Tips:
• Use with 9% or 12% developer for stronger lift.
• Keep an eye on your hair during processing to avoid over-lightening.
• Rinse with cool water after to seal the cuticle and lock in tone.
• Use co-wash after for the best results.

Sensitive scalp? Looking for a gentler option? This ammonia-free formula is your friend.
