Wondering why your client's hair turns green or red when you dye it several shades darker? In this episode, we answer that question.  You need to fill your client's hair if you are going 2 or more levels darker. That is a colour principle that you need to memorise. Any brand. Any salon. Let me break it down for you: If you are only going one shade darker - no filling is required.  If you are going 3-4 levels darker - you need to fill 2-3 shades darker. This is a double-process colour service. If you’re changing a client more than 4 levels darker,  you will probably need to do a few layers of colour, including a filler, then a colour, and a final glaze or toner. There are 3 methods that you can use for filling hair: You can fill the hair with a semi-permanent colour or toning shampoo if it’s highly sensitised or damaged. You can apply a tint or oxidate colour onto the hair and then comb it off and paint your 2nd layer over it. You can also fill hair before dying it darker with semi or demi-permanent colours. This is the most predictable, but not always the best solution for every hair type. In this episode of the Colour Kristina Talks Podcast for Hairdressers, we're talking about filling with a demi-permanent for ashy cool, warm and natural results. So if you always end up with an unwanted red tinge to your client's hair or a drab murky green, this is for you! ------------------ Want to learn more?
