Stessia hair can be considered for reuse after professional assessment. There is no single lifespan that applies to every fitting or routine.
What affects condition
Fitting, daily handling, care, styling and any chemical treatment can affect how the hair wears. Ask your professional which routine is suitable for your hair and extensions.
Check before each refit
Your professional assesses the condition of the hair, weft and attachment components before deciding what can be reused.
No fixed lifetime promise
Do not plan around a guaranteed number of months or refits. Review the actual condition at each appointment. Explore care and reuse.
