After a certain point, hair cannot be forced to lock quickly. Starting and maintenance methods can only do so much. The only way hair can completely mature is if it is given time to do so. As long as you are washing your hair regularly, there is not much that can be done to make it lock up quicker. Only time and continued friction between individual hairs can do this.
There are maintenance methods that can accelerate locks along the maturation process, but even though they tighten the lock, only time itself can complete the full maturation process.
