question answered in previous posts threads,try searching! the forums,

you can get away with up to 3 weeks, most attach weekly, fortnightly, depends really on your individual body chemistry, how quickly the heat, sweat, oils, release and breakdown the glue,
this could depend on your activity, job, hobbies, weight, time of year,

nope you don’t need a Total debond, when you experience lift,you only know it’s there,
(your choice)but a touch up is prefferable,anbd saves time,

the beauty of a front hairline touch up is the hair is already bonded 75% behind so is lined up so there’s no new hairline position to find,

the hair will lift when subject to excess water, depending on the adhesive used.
thee wonderful thing to bear in mind is there are adhesives that are water based or non-water based the non-water based adhesives are very resistant to water, as alot of wearers swim, ect with hair systems.
