Tip 1
Wait 72hrs before washing it again. You need to allow time for the colour to fully soak into the hair and for the cuticle to close and keep it trapped. Waiting 3 days with give it a better chance of lasting.
Tip 2
Use a sulfate free shampoo and conditioner. Sulfates are deep cleansing ingredient found in shampoos which causes it to lather up. However, they can be harsh on the hair and strip the hairs natural oils and colour. Try changing to a sulfate free shampoo for longer lasting colour.
Tip 3
Keep it cool. Hot water opens up the cuticle, allowing the shampoo to wash away your colour. Use warm water to shampoo and cold water to close the cuticle after conditioning.
Tip 4
Heat protection!!!! Just like hot water, hot styling tools open up the cuticle which can cause damage and allow your colour to fade. Try and keep blow-drying and hot tool styling to a minimum and always use heat protectionwhen doing so.
Tip 5
Reduce how often you wash your hair. Try to keep washing your hair to 1-2 times a week. The more you wash it, the more you are washing out your colour.
