I came to Michelle with long black packet dye hair wanting to go blonde. Michelle explained the process to me and and after one session had my hair a dark blonde! Olaplex was used and my hair is still healthy and I have had no breakage. I have been back three times (I live over an hour away) and my hair is nice and blonde and still so healthy!! Michelle and Biance are lovely and very welcoming. Highly recxommend!!
