Things you need to consider for a big change.
Decide how much time you have available to invest in maintaining your new look. Some intense or warm shades will need more upkeep.
Skin tone, eye colour and lifestyle play a big factor in what shades you should consider. Try out a similar shade from a semi-permanent collection first before taking the plunge.
Call into the salon for a friendly, no obligation consultation where you can take time to talk through your ideas with your stylist before making a decision. Gather as much information and photographs as you can to take along with you.
