Hair Dyes & Colour Treatments: 3 things to consider before buying

When selecting hair dyes & colour treatments, it's crucial to consider how the shade complements your skin tone. Warm skin tones often pair well with rich, warm colours like golden blondes or auburns, while cool skin tones can be enhanced by ash blondes or cool browns. If you're uncertain about your undertone, an easy trick is to check the veins on your wrist: greenish veins suggest a warm undertone, while bluish veins indicate a cool one.

Different hair dyes & colour treatments require varying levels of upkeep. Permanent dyes offer long-lasting results but may need regular touch-ups as roots grow out. Semi-permanent options are great for low-maintenance styles and tend to fade naturally over time without harsh lines. Think about how much time and effort you're willing to invest in maintaining your new look before making a choice.

Your hair's health should be a top priority when choosing hair dyes & colour treatments. Look for products enriched with nourishing ingredients like argan oil or keratin that help protect and strengthen your hair during the colouring process. Avoid harsh chemicals such as ammonia if you have a sensitive scalp or damaged hair, as these can cause irritation or further damage.

HAIR DYES & COLOUR TREATMENTS

FAQ

Hair dyes & colour treatments are products used to change hair colour. They include permanent, semi-permanent, and temporary options. Permanent dyes offer long-lasting results, while semi-permanent ones fade over time. Temporary treatments wash out after a few shampoos, allowing you to experiment with different shades.

Choosing the right hair dye depends on your hair type and desired outcome. Consider your natural hair colour, texture, and condition. For damaged or dry hair, opt for ammonia-free or nourishing formulas. Always perform a patch test to avoid allergic reactions.

Permanent hair dyes last the longest as they penetrate deep into the hair shaft. They provide vibrant and enduring colour but require root touch-ups as your hair grows. Semi-permanent dyes are less durable but fade gradually without leaving harsh lines.

You can use hair dye on grey hair to cover or blend it with your natural shade. Permanent dyes are most effective for complete coverage, while semi-permanent options can enhance and blend greys for a more natural look.

Using hair dyes during pregnancy is generally considered safe, but it's best to consult your healthcare provider. Opt for ammonia-free or low-chemical options and ensure good ventilation during application to minimise exposure to fumes.

Hair dye fades quickly due to factors like frequent washing, sun exposure, or using harsh shampoos. To prolong colour, use sulphate-free shampoos, limit sun exposure, and apply leave-in conditioners or UV protectants regularly.
