Colourists use the term hot roots to describe the effect where your hair’s roots are visibly warmer than the rest of your hair colour.
Hot roots generally look lighter than the colour result in your lengths, and they may have a warm, orange tone.
Why does this happen?
Hot roots occur because the heat from your scalp causes the colour at the roots to develop faster than the colour on the mid-lengths or ends. This can lead to a lighter colour result at your roots than the rest of the hair.
Hot roots can also occur if you lighten your colour. The lightening process exposes naturally occuring warmth in your hair, which contributes a lighter, brassy tone to your colour result.
Know your limitations when going lighter. Blend your colour with our 27 vol developer, which can lift 2-3 colour levels if you want to go two colour levels lighter. The 27 vol developer has a bit more strength and it can lift out more pigments while depositing colour. Brassy coloured pigments have the largest colour molecules and are the last to be lifted out of the hair. The 27 vol will remove more brassy pigments, giving a clearer, more balanced colour result when lightening.
How to avoid hot roots:
Careful colour and developer selection is critical to avoiding hot roots. Our 27 vol developer has a bit more lifting power than our 20 vol developer, and it will give you a better colour result, without brassiness, if you are colouring with a colour which is 2-3 levels lighter than your natural colour.
It is best to avoid significant colour changes, especially when lightening your hair to help avoid the hot root effect. Adding cool tones can be helpful if you are lightening, as the cool tones will mute natural warmth revealed during the lightening process, leaving a tonally balanced result.
If you have some greys and you want to colour with a warm colour (such as a golden or copper based colour), it is best to blend your warm colour with a neutral colour. The neutral colour will fill pigments which are missing from any greys at your roots.
Colours with brighter or warm tones will look lighter and brighter over greys. Blend your warm or bright colour with a neutral. The neutral pigments will anchor and fill the missing pigments in greys, leaving you with an even, consistent colour finish.
We offer Duo Colour Kits which include everything you need to blend two colours together.
We recommend that you get in touch with our colourists for personalised colour advice to help you avoid lighter, brighter colour results over your roots.
I’ve been having my heir coloured professionally for ever and decided to try to do it myself to save myself some time and money……. what could possibly go wrong?! As it turns out – nothing! It’s a simple process and the results have been excellent. It even lasts longer than my salon colour! Would highly recommend The Shade.J. Nairn
I adore my colour from The Shade. They colour matched my previous brand but The Shade is much better quality. It’s better for my hair, simple to use and I live the results. I’m definitely a repeat customer.S. Carter
OBSESSED! Honestly wish I discovered The Shade sooner. My hair feels amazing afterwards and unlike normal box dye when I dye my roots they don’t turn a horrible orange/yellow. 100% recommend!S. Harlow
