✨When should you book your next appointment? ✨ This is a frequently asked question... The answer is when ever you feel your ready. Some people are not to bothered about a years worth of growth as the colour we have created previously has allowed a natural re growth. I always advise to leave at least 6weeks between bleaching appointments to avoid over processing. GREYS- These can be covered with a tint as frequently as you like. Some peoples hair grows at a faster rate than others the average is 4-8weeks for a root tint top up.
