What is a colour correction service?<\/b>\u00a0<\/span><\/h3>\n

A colour correction helps with three things; when the shade of your hair is either too light or too dark, there are unwanted tones or the colour is patchy. \u201cThis could be a small tweak, a drastic change or when a box dye has gone wrong,\u201d Natalie explains, \u201cthere are usually a few different steps involved, compared to a normal colour service\u201d.\u00a0<\/span><\/p>\n

How long does a colour correction take?\u00a0<\/b><\/h3>\n

According to Natalie, \u201cit could be anywhere between a few hours and a few months\u201d depending on the desired look, the colour that\u2019s been done in the past and the condition of the hair. \u201cColour corrections usually take longer than a regular colour service because they require more steps, more development time and more TLC – in other words, if you\u2019re going for a colour correction, bring lunch\u201d.\u00a0<\/span><\/p>\n

Going from light to dark\u00a0<\/b><\/h3>\n

Going darker is easier than going lighter, but it\u2019s not a case of simply putting a dark colour over the top. \u201cPart of the colour correction will likely involve applying a base pigment to the hair before going in with the desired colour,\u201d Natalie explains \u201cthis is due to the way colours work together and neutralise each other”. Basically, if you put a dark brown colour over light blonde hair without a pre-pigment, it could go green. No thanks.<\/span><\/p>\n

<\/p>\n

Going from dark to light<\/b><\/h3>\n

Chances are, this will involve bleach so your stylist will need to assess how healthy the hair is. \u201cYour stylist will then be able to recommend the treatment – or a treatment plan – that will work best\u201d Natalie explains, \u201cHighlights have a low damage level but take longer to achieve a drastic colour change, balayage and full head colour treatments can be much more damaging\u201d. If the hair is in really bad condition, the plan may involve allowing the colour to fade and having regular protein treatments to strengthen prior to colouring.<\/span><\/p>\n

Correcting poorly-applied colour<\/b><\/h3>\n

This one\u2019s a bit trickier. Natalie says, \u201cIn some cases, bleach can be used but this depends on the condition of the hair, otherwise, your stylist will use techniques to mask the colour\u201d – highlights and lowlights, root drags, balayage. The key here is to be realistic about what is achievable and in what time frame, \u201cI\u2019d rather have a client come back several times but maintain the hair\u2019s integrity than try to push the hair in one sitting and damage it permanently\u201d.\u00a0<\/span><\/p>\n

Do you have any expert tips?\u00a0\u00a0<\/b><\/h3>\n

\u201cRemember to listen to your stylist – put your trust in them – if getting to the desired colour in one go will damage the hair permanently, your stylist won\u2019t do it,\u201d Natalie explains, \u201cbut that\u2019s not to say you won\u2019t get there eventually\u201d. It\u2019s also a good idea to treat the damage that colour corrections – and colouring in general – can cause. \u201cIt\u2019s worth adding an in-salon treatment (like Olaplex) and doing weekly at-home treatments to nourish and strengthen\u201d.\u00a0<\/span><\/p>\n

What is a colour correction service and when should you book one?<\/h3>\n

A colour correction service helps fix hair that is too light, too dark, has patchy colour or unwanted tones. You might need this after a box dye mishap or if you want a drastic hair colour change. The process involves several steps beyond a standard colour service to achieve a balanced, even result.<\/div>\n

\n

How long does a hair colour correction usually take?<\/h3>\n

A colour correction can take anywhere from a few hours to several months depending on your desired result, previous colour history and hair health. It usually requires more steps and more time than a regular colouring appointment. Be prepared for a longer process and consider bringing lunch to your appointment.<\/div>\n

\n

What happens if you want to go from dark hair to light hair?<\/h3>\n

Going from dark to light typically involves the use of bleach, and your stylist will first assess the condition of your hair. Treatments like highlights take longer but are less damaging, while balayage or full head colour can cause more damage. If your hair is weak, you may need to let it recover with regular protein treatments before achieving your final colour.<\/div>\n

\n

Can you fix poorly-applied or patchy hair colour with correction services?<\/h3>\n

Yes, colour correction can address poorly-applied or patchy colour, but the process can be complex. Bleach may be used if your hair is healthy enough, or your stylist might use techniques like highlights, lowlights or root drags to mask imperfections. The key is to have realistic expectations about what can be achieved safely in each session.<\/div>\n

\n

How do you care for your hair after a colour correction?<\/h3>\n

To keep hair strong after a colour correction, add in-salon treatments like Olaplex and do weekly at-home treatments. Regular nourishment and strengthening masks help reduce the damage that colouring can cause. Listening to your stylist’s advice is essential for healthy, beautiful hair in the long run.<\/div>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
