Colourists use the term hot roots to describe the effect where your hairs roots are visibly warmer, than the rest of your hair colour. Hot roots may appear lighter with an orange effect. It’s not a great look and is one that is best avoided.
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, so the colour at the roots has a lighter colour than the rest of the hair.
This can happen when you are trying to lighten your hair colour all over, or when you are colouring previously-coloured hair a lighter colour.
How to avoid hot roots?
Careful Colour Selection: We recommend colour changes which are no more than 2 levels lighter or darker than your current colour. Moderate colour changes, especially when lightening your hair help to avoid the hot root effect. Our online Colour Consultation will only select colours which are within 2 levels of your current colour, meet your hair goals and compliment your natural colour undertones. If your hair is already coloured lighter than your natural hair colour, choose a colour which matches your existing colour, do not attempt to go lighter at home.
