However it is very important to have realistic expectations when coming in for a chemical process or service.
The following information is important to know if you are a client receiving one or more chemical services:

Color history and the use of medications must be discussed when consulting with your stylist. If you are currently under the care of an MD, it is (your) responsibility to research if color services are compatible with any prescription medication or cancer treatment which you are currently being treated with, or have used prior to your color appointment. 

BELOW is a list of items to address with your colorist prior to your appointment - as these items may cause negative chemical reactions to the hair when mixed with salon chemicals services.

• Previously over-processed hair* by repeatedly layering dyes over porous pre-lightened hair.
• Taking prescription medication* that inadvertently alters the bonds of the hair (methotrexate, sulfa based medications).
• Thermal damage* by over-use of hot tools.
• Use of metallic dyes, salts, or minerals* (box dye) or use of "over mineralized well water" chemicals may cause negative reaction to enlightenment services.
• Use of henna or vegetable dyes* chemicals may cause negative reaction to enlightenment services.
• Permed or relaxed hair* chemicals may cause negative reaction to enlightenment services.

IT IS OUR PRIORITY TO CONDUCT THOROUGH CONSULTATIONS FOR ALL SERVICES PROVIDED THROUGH THE SALON, HOWEVER IT IS EACH CLIENT'S PERSONAL RESPONSIBILITY TO BE UPFRONT AND HONEST ABOUT THEIR HAIR HISTORY AND TO RESEARCH THE ITEMS LISTED ABOVE*
ANY DAMAGE CAUSED TO THE HAIR AS A RESULT OF UNDIVULGED INFORMATION DURING THE CONSULTATIONIS NOT THE RESPONSIBILITY OF THE  SALON OR STYLIST.
