Short answer: The soundest approach is to choose the treatment based on your personal needs and the current condition of your hair or skin, then follow the before and after instructions consistently.
Clarify your goal
Describe the look you like, the details you want to avoid and your daily care habits.
Share your treatment history
Don't leave out hair dye, chemical treatments, skin procedures, medication or sensitivities.
Bring a reference image
Images make the goal easier to communicate, but they are not a guarantee of an identical result given differences in hair and skin.
Allow enough time
Arrive on time, allowing for consultation, preparation and the treatment itself.
When is a professional assessment needed?
If there is an active infection, an open wound, marked sensitivity, a history of allergy, medication use or an unexpected reaction, consult a healthcare professional before any cosmetic treatment. This content is for general information and does not replace medical diagnosis or treatment.
