Longevity depends on formula, hair porosity and aftercare. Semi-permanent may last 4–6 weeks, demi 6–8 weeks, and permanent until visible regrowth. Use color-safe products and limit heat styling; schedule touch-ups every 4–8 weeks for optimal vibrancy.

Our stylists assess hair condition and choose the most suitable formula to minimize harm. Bonding treatments, proper processing times and conditioning are used to reduce damage risk. Consistent aftercare and occasional deep-conditioning maintain strength and elasticity.

A single process can effectively darken or deposit tone, but significant lightening usually requires bleach or multiple sessions. Your stylist will evaluate hair history and goals to determine if the desired change is safe in one appointment or needs a phased plan.

Arrive with dry, unwashed hair if possible and bring reference photos. Share recent chemical treatments and any allergies. Avoid heavy styling products before your visit to ensure accurate consultation and efficient application for the best result.

Semi is gentler and fades quicker, demi offers longer wear with natural blending, and permanent provides lasting coverage and lift. Choice depends on desired longevity, gray coverage, and hair condition—your stylist will recommend the ideal formula.

Plan for about 60 to 90 minutes including consultation, application, processing, rinse and styling. Time varies by hair length, thickness, chosen formula and any add-on treatments; your stylist will give a more accurate estimate when booking.
