Tresiba is a once-daily basal insulin with a duration of action beyond 42 hours, allowing for flexibility in day-to-day dosing time when needed, without compromising efficacy or risk of hypoglycaemia.
Most dreads will lock in about three to six months, but it really depends on the softness of the hair. If the hair is very soft or was previously relaxed, it can take approximately a year or so to lock.
You should probably let your new dreads go for at LEAST a week before you wash them for the first time, two weeks if you can stand it. When you first put your dreads in, they will be only made up of loose hair stuck together in locks with the wax, until about 3-6 weeks later when they actually start to mat and dread.
